Alison was the 'It Girl' and Queen Bee of Rosewood's teenage social circle, who was best friends with Hanna, Aria, Spencer, and Emily prior to her disappearance the night of September 1, 2009. Out of the girls, she is considered pretty, manipulative, secretive, devilish and vindictive. Despite her sometimes malicious behavior toward others, she can make them feel very special, and is known by her close friends to have a sweet and caring side. The daughter Alison's parents knew, though fiercely independent and recklessly obstinate when challenged, was never the girl hated and feared by many. She never had a close relationship with her brother, Jason DiLaurentis, and they often fought. Although Alison seemed to have the perfect life, she was being harassed by a mysterious text-messenger named "A", shortly before her death.
One year after her disappearance, Alison's body was found buried in the backyard of her old house, now inhabited by Maya St. Germain. The autopsy states that she suffered a blow to the head and subsequently suffocated to death, with dirt being found in her lungs. The item that was used to knock her out was discovered to be a large rock. A flashback is shown in ,"This Is A Dark Ride", of her hand coming out of the ground in her backyard, confirming she was buried alive. We later learn in A DAngerous GAme that someone grabbed her hand, trying to help her out.
In the same episode, we learn that Alison may be alive and secretly be Red Coat, the mysterious blonde who appears to be stalking her former friends. Her potential existence ultimately raises a number of questions, especially concerning the body that was discovered in the pilot episode and where Ali has been.
In "Now You See Me, Now You Don't", it is confirmed that Alison is alive. Carla Grunwald revealed that she had pulled Alison from the shallow grave. She said Alison was afraid of "A" and would call her for help because she is psychic. In Grave New World, the liars finally catch Alison in her red coat, used as a disguise from "A". She says that she cannot come back because someone is after her. She escapes when the liars have their backs turned.
In "A is for Answers", the liars find Alison again and she explains what happened the night she went missing, confirming all the people she met that night throughout the way who she thought was "A" (including Garrett, Jenna, Ian, Ezra, Toby, Byron etc). She then reveals that she was hit over the head by a rock and not a shovel by an unknown person.. Her mother witnessed this and subsequently buried her alive, not realizing she wasn't dead and in order to cover the person who did it. She confirms that Mrs. Grunwald rescued her but then she ran away from her. She then reveals that Mona Vanderwaal found her and took her to the Lost Woods Resort and gave her the idea to fake her death from "A". It's later revealed Mona was Alison's "A", but she was NOT the one who hit Alison with the rock. The next morning, Alison dressed as Vivian Darkbloom, leaves town much to Mona's delight.
Alison returns to Rosewood in Whirly Girlie, shocking everyone of her "coming back from the dead". Throughout the next episodes, Alison and the liars try to find out who the ruthless "A" is, when the liars and Mona begin to suspect Alison of being "A", as part of her "biggest game yet".
In "Through a Glass, Darkly", Alison was arrested for the murders of Mona Vanderwaal, and Bethany Young.
Although Alison seemed to have it all, she was easily threatened by people who intimidate her. Her jealousy and need for power often got the best of her and caused her to act cruel and selfish; likewise her fearless nature had helped her to get revenge on her enemies numerous times. Alison was vindictive and cunning, she often used other people as tools in her manipulations - she was the snake behind an angel's face.
Nobody told a lie better than Alison DiLaurentis. She had a way of using people's secrets against them She had kept lots of information about her life from her friends, while managing to acquire all of their secrets. Alison often held private knowledge of her friends over them to stay in control. She spun a web of lies so tangled that her friends were left to deal with the resentful "A" when she was on the run.
Since season 5b and onwards, Alison's personality has changed significantly. She has become a better person. She is now more reserved, and wants nothing more than to be happy. Though, if someone or something threatens her or her friends, she has no problem letting her "bitchy" side shine through.
Though Alison has become less threatening, she is NOT a pushover. She has been through so much, yet she is still so strong.
Alison is a very attractive young girl. She has golden blonde hair; which is mostly in curls, blue eyes, and a heart-shaped face. She is slender and graceful, and wears fashionable and feminine attire. Alison's bold personality is reflected in her confident stance.
The series begins with footage of the night Alison DiLaurentis disappeared. Alison, Aria Montgomery, Spencer Hastings, Hanna Marin and Emily Fields were having a sleepover party in Spencer's barn. Alison scared them by sneaking up on them in the barn doorway, causing them all to laugh. Aria, Hanna and Emily later wake up from their sleep and realize Spencer and Ali are both missing. Spencer then returns to tell the other girls that she looked for Ali everywhere and thinks she heard her scream. She later seen in flashbacks such as when her and Aria catch Aria's, Byron Montgomery, having an affair or when she blackmailed Spencer to confess to flirting with Ian Thomas to Melissa Hastings or she would. Later, Spencer looks out the window and sees into the window of Alison's house across from hers, a wavy blonde figure moving about inside. Spencer gasps, "Alison." Her body is supposedly discovered in her backyard.
Alison reveals to the girls that she believes Toby Cavanaugh is spying on them while they were trying on clothes in Emily's room, and has been for some time. Alison immediately hatches a plan to drop a stink bomb in his garage as revenge. Emily and Aria try to back out, while Hanna and Spencer also share their reservations, but Ali is adamant that Toby must be taught a lesson. Alison then orders Spencer to pass the match and ignites the firecracker, opening the door of the garage, and tossing it inside. But the prank went terribly wrong when the garage catches on fire, and Alison sees too late that someone, Jenna Marshall, was inside. As a result, Jenna was blinded from the accident, and Alison made sure that Toby falsely took the blame for it. Alison had blackmailed him with a piece of information that Spencer could not overhear.
Hanna remembers of the time in her chubby days when she asked Sean out to a party. She had asked him with a nervous, quavering voice, and Alison had stepping in, pointing out that everyone was going. She made eyes at him, and he accepted, perhaps because he really found Hanna charming or perhaps because Alison had been hard to resist. At Noel Kahn's cabin party, Spencer suddenly recalls the night of "The Jenna Thing," when the girls had to deal with the aftermath. Alison had been standing in front of the Cavanaugh house, blackmailing Toby with something to get him to take the hit for the fire in the garage. Spencer had walked over to listen, and Alison angrily pushed her back, angry that she violated her order to stay away. She follows Spencer to where the other girls are standing and tells her friends that she would have not set off the bomb in the garage if she had known someone was in there, even though it seems that she did see Toby and Jenna in there. Hanna expresses her desire to come clean to the police and explain it was an accident, but Alison rails on Hanna, basically calling her a fat loser until Aria scolds her, forcing her to apologize. But Alison makes sure she gets her way and makes the girls flee the scene, letting Toby take the fall. Spencer remembers seeing Toby as he was taken away in the cop car to the police station.
Aria watches her mother preparing dinner in the kitchen. She suddenly recalls the incident she witnessed, involving her father and Meredith kissing in his car. This time, she additionally remembers how Alison had tried to convince her to tell her mother what she saw. When Byron had tried to call Aria, Alison had warned her not to pick up, correctly suspecting that he would try to talk Aria out of revealing what she saw. Alison had warned Aria that she could risk losing both parents if she didn't tell.
It is later revealed that Alison was threatening Toby to take responsibility for the fire, but he had told her that he will make sure she takes responsibility. In turn, she had threatened that if he tells, she would tell everyone Jenna and Toby had a sexual relationship. Spencer had come to see what was going on and Alison angrily yells at her to let her take care of it. The girls talk as the firetrucks show up, and are freaking out. Hanna begins to doubt Ali, and Alison starts to insult Hanna, basically calling her a fat loser. Aria scolds her and Alison apologizes, and that she's just freaked out.
Preparations for Alison's memorial sparks memories of a summer day that the girls had spent lounging by the lakeshore. Ironically, the girls had spoken about immortality and the fantasy of living in this moment forever. Alison had said that one could only attain immortality by dying young and leaving behind a beautiful corpse. Alison had also romanticized how fabulous it would be to die in a mysterious way. The days goes on with Alison annoyed that Jenna was there, asking Aria if she needed help getting Noel Kahn to herself, bullying Lucas Gottesman until Hanna tries to stand up to her, and asking Emily who she would like to take to The Kissing Rock.
Emily is directed by "A" to the school library's copy of "Great Expectations," the same book Alison had been reading one day alone in the library. Emily hears Alison's laugh and sees a blonde sitting on the floor, a book on the shelf covering her face. She pulls it off and it is revealed to be Alison. A moment later, she is gone. She has a flashback of that day. Emily had joined her on the floor, and Alison had stroked Emily's hair affectionately. Emily revealed her dream that Jenna could see again, and Alison said something about Emily's positive, perhaps naïve, attitude, to the effect of "that's why I love you, Emily." She then read her the passage of Pip's account of his ardent love for Estella: he loved her against reason and despite the fact that she basically played hard-to-get and gave him little hope for a future, in spite of her teasing. Quite fittingly, Emily then leaned in to kiss Alison, expressing her own love of the same nature. Alison actually smiled in return. However Emily flashes to a locker where after trying to be flirtatious, Alison coldly tells her that their kiss was practice for the real thing.
Spencer tries to convince Melissa to reunite with Ian. Afterwards, she flashes back to the previous summer when she had been practicing her field hockey swing on the front lawn. Ian had walked by, and, under the pretense of correcting her technique, put his arms around her waist and leaned in to kiss her neck. Surprised, Spencer had turned around to face him, and this, too, ended in a series of mouth kisses. After Ian walked away, Alison called out from where she was standing a few meters away to let Spencer know that she saw her kissing her sister's boyfriend. She called it disgusting and basically called Spencer a skank to boot, implying Alison's jealousy.
Alison donned in a candy striper outfit visiting her in her hospital room. She smiles at Hanna and asks if she misses her. Weak, Hanna tries to ask her what happened that fateful night, but all Alison will say is that the four of them combined already know the truth. Additionally, she tells Hanna that "A" annoys her, and that she should really do something about that bitch. She reveals that it is dangerous for her to have come, but she did because she had to see if Hanna was ok. When she leaves, a berry-colored lipstick stain - the same shade that Alison is wearing - is seen on the rim of a Styrofoam cup near Hanna's bed.
Hanna is in her wheelchair at the party Mona has thrown for her, when Noel walks in. Just the sight of Noel prompts Hanna to have a flashback about him at a different party, when Alison had manipulated a girl to dump Noel, who gave him a nasty look in return. Alison had claimed that they were all responsible, when it is obvious that the girls had been oblivious to how Alison had even managed to break them up in the first place. She claims that she did it for Aria, so she could have him instead, and that she only kills when they need food. Later, Spencer sees a "Hilton Head" resort tag on Ian's luggage and flashes back to Alison returning from an alleged weekend visit with her grandma in Georgia with the same tag hanging from her luggage. When Spencer tried to question Alison about the club's location being in South Carolina and her grandmother being in Georgia, Alison deflected the questions derisively, then expressed how eager she was to share her vacation stories with the other Liars. This is the day that Alison disappeared.
When Hanna is forced to eat a half dozen cupcakes by "A," she flashes back to one day when she had eaten an entire pie in her kitchen at home. Alison had walked in on her and Hanna quickly tried to clear the evidence by throwing it in the garbage; however, Alison had seen it anyway. Hanna broke down into tears, and Alison comforted her friend, hugging her and murmuring, "I understand." She then wiped away Hanna's tears and told her that she didn't have to feel that way, and she could show her how to get rid of it. Presumably, Alison had shown Hanna how to purge the calories she had just binged.
The girls reexamine of Alison talking to Ian and think of the possibility that he killed her.
Spencer guiltily recalls how the night she disappeared, Alison had pressured Spencer to tell her sister about kissing Ian, something that would've left Ian all for Alison. Spencer refused, but Alison warned that Melissa would find out the next day, whether Spencer told her or not. Alison arrogantly claimed that Spencer and the other Liars were her puppets. Spencer furiously countered that she was sick of her games, that she would tell Melissa, but Alison was dead to her already. Alison appeared distraught, then left angrily, and after a moment's pause, Spencer marched outside after her.
The girls flashback to a college party Alison had taken them to, probably in an effort to spy on Ian. Ian had been flirting with a particular tipsy girl and had gone off with her to one of the rooms upstairs. Later, that girl took a nasty tumble down the stairs. The girls all exchanged looks after her fall, and in hindsight, they are left to question whether Ian, or Ali, had pushed that girl. Later that evening, the Liars stood on the lawn, discussing the incident, as a stretcher passed by. When Alison showed up, she had seemed either oblivious to the girl's accident or indifferent. At the same time, the girls were afraid of being caught being underage at a drinking party, which was very likely with the police swarming about. Alison had taken charge of the situation, brazenly asking a police officer for a ride home in his cop car, claiming to be too tipsy to get behind the wheel, when in reality she didn't want to take the bus and was too young to even drive. She wisely explained, "the bolder the move, the less anyone questions it." The girls got into the car as Alison exchanged a look with Ian on the porch.
Emily makes a discovery after the Rosewood Founder's Festival. Emily reverts to the last time she saw Alison before the sleepover; she had visited Emily in her bedroom to give her a snow globe as a souvenir gift from her vacation. As she had not bought any gifts for the others, she asked Emily to keep it a secret from them. She mysteriously alluded to the fact that it was more special than one would realize at first. This flashback prompts Emily to examine the toy, and at the bottom, she finds a key with numbers printed on it. Thanks to the clue, Emily, Aria and Hanna track down the matching location and uncover a flash drive contained in a lunch box, housed in a storage unit that Alison had rented! The flash drive contains secret videos, mostly of the girls in private moments such as getting dressed in their bedrooms; Alison had somehow known that they were being spied on while she was alive. There is footage of Jenna on these videos as well, meaning that the Liars hadn't been the only girls to be spied on.
The girls corner Jenna to confront her about the incriminating video they found of her and Toby. Jenna discloses that Ali had visited her in the hospital on the day that she disappeared. She played the video footage of Jenna seducing her brother, and Jenna fumingly asked Alison were she got it. Alison replied that the guy she liked to make videos, perhaps vaguely referring to Ian. She threatened Jenna that if she ever told anyone about the Liars setting the fire, she would release the damaging videos. Jenna could only sit exasperated before Ali took the computer and moved to leave. Alison then turned to warn Jenna that if she ever returned to Rosewood, she would bury her. The Liars believe Jenna's account, given how it explains her seemingly strange speech at Alison's memorial dedication.
After Jason DiLaurentis returns to his former home, Spencer drops by to give him cookies in hopes of finding out information from him. It turns out Jason wants information from her, but when she is not specific enough about whether Ian actually confessed to killing Alison, he returns inside. While still standing on the stoop, Spencer flashes back to one summer when Ali and the Liars' were lounging in the DiLaurentis' front yard. Jason had stormed out of the house, accusing Alison of messing with his stuff. She had retorted back sharply, mocking him and his friends for being stoners. When Jason went back into the house, they questioned Alison whether she had stolen what he claimed she had. She admitted it gleefully. She mischievously replied that he would never find it, because when she wants something to stay hidden, it stays hid. Alison says she has hiding places everywhere, including the yard. She says that's why their secrets are so safe with her. Just then, a smashing sound was heard from inside the house, though Alison seemed unfazed.
Spencer has a flashback of a time Emily was sleeping over at her house. Alison knocks on the backdoor, and appears to be enraged. Her brother is having a noisy party, and implies his friends, or "animals", as she call them, are harassing her. Spencer tells Alison she is welcomed to stay, to which Alison replies "Thanks". She grabs an apple and goes to wash it. She looks at her reflection in the window, and looks like she is about to cry. Spencer asks if she's okay, and Ali returns to her normal self. She says she was just thinking about her grandma. She eats the apple and wrinkles her nose in disgust. "Your family has the worst apples", she says.
Hanna tells Dr. Sullivan her true feelings about Alison, in hopes of letting go. Her role playing makes it seem that Alison is really there, taunting Hanna about her feelings. Hanna calls Alison the best friend she ever had, but also her worst enemy. Alison is condescending, but Hanna doesn't allow the mental torture to continue, not caring whether Alison approves of her anymore. In her head, Alison calls Hanna's friends things that Alison has given her and insinuates that Hanna can't live without her. But, mentally, Hanna lets the ghost know that she is over her, that she won't let her into her life anymore, and that she is ready to move on.
A leads the girls to the cemetery, where Alison's grave is. Suddenly, a projector plays the video of Alison and Ian at the Kissing Rock. The video plays the footage the girls already have seen before. Alison falls to the ground, her hand going limp. This time, however, Alison gets up, laughing. She kisses Ian and thanks Ian for meeting her, revealing Ian did not kill Alison.
The Liars lunch with Ali's mother, Jessica DiLaurentis, as per her request. There, she presents the girls with presents, four high-fashion dress. However, the girls are uneasy, as they remember Alison having picked them out and trying them on one afternoon. She said to Emily "Don't I look hot, Em?" as she was aware of Emily's crush on her. Emily says the feathers on the dress look really pretty. Hanna spots another dress, and says "This stretch size is to die! Can I try it on?" to which Ali rudely replies "There's not that much stretch," making fun of Hanna's weight. She then compares the dresses to her friends: Unique and belonging to her.
After Toby shares news of the hockey stick discovery with Spencer, she flashes back to when Alison had asked Spencer to teach her how to play field hockey. Spencer had been happy to lend Ali her old hockey stick with the Rosewood Field Hockey team colors on it - blue and white. Aria had questioned Ali's motives at the time, knowing that Alison wasn't the biggest field hockey fan. She guessed that it was about a guy, which was probably correct. Spencer said that guys don't play field hockey, not putting it together that Alison was either interested in or already dating Ian, the field hockey coach. Aria's flashback of Jason the day that Spencer had been showing Ali how to hold the hockey stick incriminates him. He had come looking for her on their mother's orders, unhappy to have to waste time looking for Ali. When he caught sight of the stick, he grabbed it from her and then threatened to hit her and Spencer let out a warning cry. When Jason turned around, Ali tried to whack her brother with the stick, but Jason moved quickly, and mockingly warned Ali that she wouldn't get a second chance.
Spencer flashes back to the summer before Alison had disappeared. The girls had been standing in Hanna's kitchen, and Hanna's grandmother Regina Marin had been over as well. She was talking about her two sons, Tom and Patrick, and Alison suddenly asked what it would take to cut one of them from her will. Regina was taken aback by the question, but Alison had pressed on, asking hypothetically, if one of her sons sold an expensive family heirloom to buy drugs, would that warrant dismissal from the family tree? Regina ultimately said yes. In retrospect, Spencer believes Alison to have been referring to her own family situation and thinks that Alison had gone to Georgia in order to try and get her grandmother to cut Jason out of the will.
Emily is trapped in a barn by "A." Someone drags her unconscious body out, and wakes up on someone's lap in a sunny field. The person bends over, and it is Alison. She tells her it's okay, and that she's with her now. She says that she misses her the most, and that Emily was always her favorite. Emily asks if she's dying, but Alison ignores the question, and says "that bitch thinks this is what you really want. To be completely free of "A." Emily tells her to say who "A" is, but Alison says no because "Two can only keep a secret, if one of them is dead." She then gives Emily a choice: to come with her, or stay here. Emily closes her eyes and Alison says "Sweet Emily." She then kisses Emily and Emily wakes up in front of the barn. The other liars find her and Emily tells them Alison is alive. Since Emily was outside of the barn, this means clearly someone dragged her out. It's revealed in Season 4, that Alison is alive, meaning this had actually happened. Alison really did drag Emily out.
In October of 2008, Alison and the girls walk to school debating Halloween costumes when Noel drives up in a convertible with his jock friends to greet the Liars and invite them to his party. Before the party, she meets Jenna, flirts with Ian, bullies Mona and Lucas, and receives her first "A" messages, one of which is a voodoo doll with a note saying "It's my turn to torture." At the party, as Lady Gaga, Alison confront Jenna who is wearing a similar costume. She offer her a spot in her clique, but Jenna turns her down. Later, she stages a test to see how loyal her friends are. She conspired with Noel to lure to the girls to a local abandoned house where she had them believe she was in danger. Her friends are annoyed and betrayed by Alison's crying wolf, but are silent. Back at the party, there seems to be mostly college kids now. Alison approaches Ian and flirtatiously strikes up a conversation with him. But, Melissa cuts her off by spinning Ian around and planting a kiss on his lips. Disgruntled, Ali walks back to her friends. Noel apologizes for missing the prank. It turns out that someone else tried to actually hurt her. Alison gets a text: "Dying to know who I am? You’ll find out. –A."
After the Liars find a note inside Alison's baby doll (Next time it'll be your face, not this pumpkin), they all have a flashback to Halloween 2008. Alison and the Liars were taking a shortcut to her house and when they arrived, they found some smashed jack-o-lanterns on the porch and a note left under a knife. Aria reached out to take the knife, but Ali suddenly grabbed it. When the girls asked if the note says anything about who caused the destruction, Ali said it was Jason's "beer buddies," then, scared, she invited the girls to sleep over. They made excuses but Alison apologized about what happened, saying she had gone too far and the girls likely stayed over. Back in real time, the Liars discover that the note was signed by "A," meaning Alison was a victim of "A" as well.
Spencer goes at Hanna's to apologize about working with Caleb Rivers behind her back. Hanna forgives her and says that she had actually seen Ali with dark hair once before. She flashes back to a day when she was at a hair salon and heard a familiar voice talking to the stylist. The man referred to the dark-haired girl as Vivian Darkbloom. After he left, Hanna realized that "Vivian" was actually Alison. Alison asked her what she was doing there, and she said that her mom made her an appointment. Hanna told Alison she liked her new hair. Alison told her that she was pretending to be someone else because she was getting bored of always being herself and suggested Hanna should try it sometime too. Alison asked Hanna to keep it a secret, then she took off her wig, smiling. When Spencer Google's the name Vivian Darkbloom, she and Hanna find out that the name was an alter-ego of Vladimir Nobokov, the man who wrote "Lolita," which apparently Hanna had seen Alison read.
When Spencer tries to understand what is it that links Jason to her family, she flashes back to a night when Alison and Spencer were in Spencer's bedroom. Alison was reading a magazine and Spencer studying for a test. They heard Spencer's parents arguing downstairs and Alison asked what it was all about. Spencer told her that her father saw Melissa and Jason making out the other night and he's upset because of that. Alison wanted to open the door to hear what going on exactly and then said that Melissa and Jason would be "a match frowned upon by the gods." Spencer didn't catch her drift until over a year later.
Spencer wakes up in the middle of the night in her living room to find Alison rummaging through the bag Jason gave her. Alison asks Spencer not to scream, claiming she only needs something from the bag. Alison asks Spencer if she is mad at her for never telling her about Jason being her brother too. Alison says that by sharing a brother, it practically makes them sisters and that Spencer deserves a more decent sister. If she had told Spencer the truth about Jason, it would have changed everything. Alison sees a bottle of pain killers on the table, and asks to take a couple "for the road." She also says that it is now helpful the girls have the bag. She gives her a hint by telling her to look at the big picture instead of scrutinizing the individual pieces. Spencer asks what is in the bag that is so important, but Ali says she can't say. She states she misses Spencer and that everything the girls are dealing with is "some seriously messed up stuff." Ali informs Spencer, "here's the good news, you're getting warmer." Suddenly, Spencer and Alison hear a noise coming from upstairs, so Spencer stuffs the bag underneath the couch and falls back asleep.
Mona tells Spencer, that when she was in a clothing store, she saw Alison (who was dressed as Vivian) and that she was spying on someone. Mona, who was then a hopeless nerd, begs Ali to tell her what she is doing. Alison finally tells her she is spying on someone, and Alison asks her what it is going to take for Mona to leave and forget what happened, and Mona responds "to be popular." Alison gives Mona a phone number, written on a torn post card for the "Lost Woods Resort. It is unknown if this actually happened or not due to Mona revealing herself as "A".
Hanna visits Mona in Radley Sanitarium thinking that her visits are helping. Mona turns and smiles, and Hanna thinks she's smiling at her, but she realizes Mona is actually smiling at the chair behind her. Mona hallucinates Alison sitting there in a red coat, with her natural blonde hair color, reading "Lolita." Mona and the audience can see her, but Hanna can't. Alison's body is also stolen from her grave by "A."
Aria finds an earring in her locker, a "gift" from "A," and she has a flashback of a night when she and Alison snuck into Byron's office to find out if he was still cheating with Meredith. Alison finds one earring in the couch cushions and Aria freaks out. Upset and angry, she lets Alison talk her into trashing the office and letting him believe Meredith did it. Before Alison "finds" the earring, you can see it sparkling in her hand, meaning she had actually planted the earring there. Meredith also states the earring is not hers, further proving Alison planted it.
Spencer finds Alison's beloved anklet in an antique shop, reminding her of a night Alison had come over for a sleepover. Spencer notices Ali's charm anklet and Ali says it was from a friend, not a boyfriend, and that Spencer doesn't know "her." Ali had come over to watch movies with Spencer, but then ditches her to go to a party in order to get the girls fake IDs so they can get into frat parties and have a great summer. Spencer is upset, but as usual Ali gets her way. Her friend is waiting to pick her up downstairs, and we can assume that this friend was CeCe Drake, Jason's girlfriend.

The girls find out there are two Red Coats, one of them being CeCe. They believe the other is Alison, who appears to be helping her old friends; she saved Emily's life from the sawmill, and she led the girls to A's main lair.

When she arrived there, Alison's hand was coming out of the ground. Carla pulled Alison out of the ground, confirming Alison is indeed alive. Alison was crying and seemed very confused. She drove Alison to a hospital, and Carla ran in to get help. When she returned, Alison was gone. Carla says that Alison does not want to be found, not just yet. Carla also says they need to leave Ravenswood, because "he" is watching them, hoping that they will lead "him" to Alison. "He" is revealed to be Ezra Fitz. The Liars find out Alison will be at a celebration Ravenswood is having, and must race to find her before "He" does.
The girls dressed in their old-fashioned costumes, go to the celebration at the Ravenswood Cemetery in search of Alison. They later see Red Coat running into a crypt. The girls follow her, but she disappears before they could catch her. When Ezra takes the girls back to Rosewood, The girls spot Red Coat and follows her to Spencer's barn. They watch her from behind as she slowly takes off her hood and turns around. It is Alison. She asks them if they missed her, and then tells them that it still isn't safe yet. Emily asks Alison not to leave again, and she reveals that she wants to come home, but she needs their help. Then she tells Hanna to remember what she told her in the hospital (Moments Later). A light comes up behind the liars and she motions for them to be quiet. They turn around to see Ezra. He claims that Aria left her phone is his car and hands it to her, looking behind them. They all turn around. Alison is gone.
Emily is sleeping with her window wide open. Alison walks through the window, waking Emily up. Alison tells Emily how much she missed her, but Emily doesn't want to hear it. Emily says that she has been here the whole time, Ali is the one who was gone. Emily tells Alison she destroyed her because she thought she was dead. Alison picks up her journal on Emily's bed. Alison says she thought she was being smart, writing everything down in a journal. Alison tells Emily she wants her help because she always saw the good in her. Emily says she doesn't see that anymore. Ali notices the Jenna-Thing string bracelet on her wrist, and is shocked to see she still wears it. Emily wakes up from her dream. The Liars realize Ali used fake names in her journal. They read one story titled "The Cradle Robber". Hanna admits she is the Cradle Robber, and has a flashback to a time the girls were having a sleepover at Aria's. Alison had caught Hanna and Mike together, and tells her how wrong and gross it is. Hanna says "He was nice to me"!, to which Alison replies "Oh, please. He just wanted to feel your boobs. And you let him." Hanna says she isn't pretty or perfect like the rest of them. Alison says "That doesn't mean you have to settle for being a Cradle Robber". Hanna begs Alison not tell Aria, and Alison agrees not to. Alison tells Hanna she will find someone who will love her exactly for who she is. It may just take her longer than the rest of them, that's all.
Emily finds out Shana has been helping Alison, because they were childhood friends. Emily asks for proof, and Shana tells her things only Alison would know. For example, Shana recited the exact conversation Emily and Ali had when Ali pulled her out of the barn, revealing Alison really did save Emily. Shana tells Emily that Alison wants to meet Emily. Tonight. That night, Shana drives Ali to an abandoned warehouse. Emily turns around, and Alison is there. They hug, and Emily begs Alison to come back. Alison says she doesn't know who she can trust. Emily asks who she is hiding from, and Alison replies, "I thought I knew...but I was wrong". Ali says she trusts Emily, but is not so sure about the others. They hear a noise, and a scared Ali takes off to the elevators. Emily sees that it's Spencer. Emily runs after Ali, but it's too late. Alison is gone.
Spencer is reading a story in Ali's journal, titled "The Hart and the Huntsman". Spencer visualizes the story in her head, and we see Alison on a date. We do not see who she is talking to. Spencer is playing "The Huntsman". Alison says to the man "So...what do you think about my story?". Spencer reads the mans dialogue. "You have a strong voice" The man says. Alison asks what is wrong with it. The man says her story is only going to get more distinctive as she grows up. "Grow up?" Alison curiously replies. "You know what I mean. Mature". The man says. "Oh, so you don't think I'm mature enough?" The man says that literature boils down to two things: Love and death. Alison then comments on what he ordered: Boysenberry Pie with beer. Alison says she might write a story about this very moment. She leans in and kisses the man. Later, Spencer goes to the bar Alison and Board Shorts went to. She sees Ezra and he is eating none other than Board Shorts Ale and Boysenberry pie. Spencer has the same flashback of Alison's date, but realizes the man she was with was Ezra.
We see Alison in a phone booth. She is talking to Shana. Alison asks Shana if she "can get it". Later, Shana asks Emily if she can get something for Ali. There is something behind the French Twins poster in Alison's bedroom that Ali needs. Emily retrieves it, and it is a lot of money. Shana asks Emily to meet her later so Emily can give the money to Shana. Shana never shows, because "A" attacks Shana and she wakes up in her car. Ali calls Shana and asks if she got the money. Shana looks and sees the Rosewood Sign that reads "You are now leaving Rosewood. Please come back again". However, "A" crossed out "please" with red paint and wrote "Don't". Shana gasps and hangs up before taking off. Alison tried to look through her wallet for some money, only having a couple of dollars. She stares at a picture of herself with the other liars. Alison gets on a bus, and cries.
Thanks to Spencer's drug use, she has a dream that transports her and everyone to a black-and-white noir film world. In this dream, Spencer, dressed in her black and white attire, turns around and sees Alison. Alison is staring a painting of herself that is unusually hanging on Spencer's wall. Ali is wearing the same dress and pose as the painting has. Spencer gets mad at Ali and demands when she will get answers. Alison laughs in her face about how pathetic Spencer's drug use is. Alison says to Spencer "Maybe you're the one I should be afraid of". Alison vanishes. Later, the girls find Ali working at a nightclub. Ali is being her bitchy self. Alison says Spencer is bossy, and claims Spencer tried to kill her once. Spencer says "lets see how long you last out here without us". Spencer claims Alison is setting them up for something. Ali asks Aria if Spencer told her. Aria looks confused, when a gunshot is heard. They all run and hear Ezra's voice. However, it's actually Toby who says he hit Ezra with his car. Ali is gone.
Spencer steals papers from Ezra's apartment. She reads one that says CeCe witnessed a fight between Spencer and Ali the night Ali went missing. Spencer has a flashback, which is continuing the flashback from If At First You Don't Succeed, Lie, Lie Again. After their argument inside Spencer's house, Ali storms out. Spencer follows, angrily yelling at Ali to stop. Alison says that they are over. Spencer grabs a shovel and Ali yells "You are way out of your league, Spencer"! Spencer lifts the shovel, and says "Am I? You sure about that?". Alison looks a bit scared and says "Why don't you put that thing down before you hurt yourself". Spencer doesn't remember what happened next, but the paper says Mrs. DiLaurentis also witnessed the fight and paid CeCe not to tell. Spencer fears she could have been the one who tried to kill Alison.
In a flashback, Jason was on the couch, when Alison and Jessica walk through the door. They are talking about "A". Ali, who appears to be scared, says the notes are anonymous and Jessica tells Ali she thinks it's Spencer. She tells Alison to defend herself and to smoke Spencer out. Jason reveals himself and Jessica asks how long he was there. Jason smirks in response. Veronica has a flashback of a time when Spencer was using drugs for the first time. Spencer and Melissa had gotten into a huge argument and trashed each others things. Alison walks up to Veronica who is outside cleaning up the huge mess. She is visibly upset. Alison asks to help, but Veronica tells her to leave. Veronica says she doesn't understand what's happening to her family. Alison says she wishes she knew too. Alison turns to leave, when she sees a sick-looking Spencer staring at her. Emily and Hanna sneak into Alison's room and manage to log into an email she was using. They message Ali, and Alison calls them, asking how they found her. She tells them to meet her, giving an address. The liars go to that address, and try to find Ali.
She sits down with them and tells them everything that happened the night she went missing. From Hilton with Ian to blackmailing Jenna in Philadelphia. After she gets a death threat from "A," Alison decides to find out who "A" was that night. Ezra confronts her about lying t him about her age when they dated and asks not tot find him again. When the Liars are ruled out, she confronts Ian about his videos where he tells her that revealing will "bring everybody down." After the argument with Spencer, she waits at the barn for another text but nothing happened. She went home thinking it was finally over, but someone hits her from behind with a rock and her mother buries her thinking that she's dead. Alison confirms that Carla Grunwald pulled her from the ground. Alison ran from her because she was scared. Alison is walking aimlessly, until Mona picked her up. Mona gives her the idea to disappear and in return, she gave Mona tips on changing her look. Back to the present, someone id shooting at the Liars and they are chased up the rooftop. Ezra appears and begins to fight "A", claiming he knows who it is. Hanna grabs the gun and they all yell for shim to take off the mask. "A" reaches for the mask, but jumps off the ledge. "A" pulls themselves to safety and runs away. The girls see in horror that Ezra has been shot.
Afraid of being seen in the public eye, Alison watches Ezra being loaded into an ambulance from a balcony above. With height giving her an advantage, Alison notices 'A' lying flat on the top of the ambulance as it drives away. Alison leads ‘A’ out of the hospital and on the streets of New York, eventually running into a playground and hiding behind some equipment. It isn’t long before the four girls are surrounded by multiple people claiming they are A. As the police drive past and break the flash mob up, Alison tells the other girls A was one step ahead of them. Eventually, she meets up with CeCe and Noel. She gives CeCe her passport and her plane ticket. In the dressing room of the Fitzgerald Theatre, Alison tells Emily that Ezra was paying CeCe for information and that’s why CeCe was in Ravenswood. Alison goes on to say CeCe was never really Red Coat, Alison had just asked her to wear it, hoping that she’d distract A long enough so Alison could turn off the saw. As the girls run out onto the stage, the lights in the Theater go out and Shana walks onto the stage with a gun. Shana tells them they she thought she had them all locked in the lodge, but Alison was late to the party. Alison doesn’t understand why she would turn on her. Shana tells Alison and the girls that what she is doing is justice, and when Spencer asks for who, Alison realises who, “for Jenna. You fell in love with her”. Alison tells her that Jenna doesn’t love her, “she’s playing you. That’s what she does”. After Aria knocks Shana of the stage, killing her, Hanna embraces an upset Alison.
Arriving back in Rosewood, Alison hesitates as she gets off the bus, but Emily manages to convince her to take the final few steps. Entering the Police Department, Alison and the other girls are greeted by Gabriel Holbrook and she tells him that she didn’t disappear, she was kidnapped and held hostage for two years. She goes on t say that she escaped her captor in Ravenswood and the girls hid her in the woods, in a shed that they all used to hang out in. Before Holbrook can press any further questions, Mr. DiLaurentis arrives, reuniting Alison with her father. At home, she gets a text message, "the truth will bury you in a New York minute." Kenneth tells her she can sleep downstairs if she prefers, but Alison tells him she’s been dreaming of sleeping in her own bed again. As he’s leaving her room, Kenneth tells Alison that he and her mother are getting a divorce, something she already knows, “I know. Emily told me”. Later, Alison sneaks at the Mausoleum saying goodbye to the girl who was buried in her grave, when Mona comes up behind her. Alison tells Mona that she can't be the person in hiding anymore and offer her hand in friendship. Mona then tells Alison that she was the one who sent the text message and threatens to make her life horrible. As Jessica's body is lifted from the shallow grave and zipped into a body bag, a hooded Alison silently weeps by herself.
Alison is lying numbly on her bed in the days following the discovery of Jessica’s body. She ignores everything and everyone around her until the day of the funeral. At funeral home, Alison relates a story to Hanna on how Jessica would drag her along to all her relatives' funerals. She tells Aria about Mona's threat and fears the outcome if she returns to Rosewood High. She reads Ezra's manuscript and she asks Ezra if he left and he confirms it. She also thanks him for helping her and girls in New York. Having left Ezra’s apartment, Alison is walking down the street. Peter Hastings notices her walking alone and calls out to her and offers her a ride home.
Kenneth drops by Ali’s bedroom and tells her the police need her to go in for a medical exam, and they can’t keep putting it off. Alison calls Hanna, who is the only one of her friends to answer, and tells her that she’s going in for a medical exam tomorrow and she doesn’t want to go alone, “can you please come with me?” Hanna agrees to go with her and asks what time she should pick Alison up. Alison is having her medical exam, where the doctor tells her she has quite powerful lungs, before asking her to tilt her head so he can take a lot at the place where she was injured. The doctor tells Alison he’d like her to come in for an x-ray as the scar tissue on her head may have trapped particles from whatever caused the wound. The doctor notices a scar on her thigh. She claims it happened when she escaped though the doctor does not quite believe her. She gives the girls a tape recorder of statements the girls had to memorize for when the police start asking more questions. When her and Spencer talk, Alison tells her that somebody messed with Jessica’s pills. Jessica has low blood pressure and the pills in her system were the wrong ones and they stopped her heart.
Alison is giving herself a little pep talk as she’s getting ready for her first day back at Rosewood High, "you've been through a lot worse. You can do this". At school, she walks in with the girls with her head held against any odds. After school, she is at Emily's house where she confesses to Emily that not all of her kisses to her were just practice leaving Emily confused. At the church, Mona confronts her with the New York incident and tells her to leave again. Alison is not deterred claiming if Mona had proof, she would've done something by now. So goes on to tell her she's afraid because it long until her army is won over. “I made you Loser Mona once, and you know I can do it again”. Angry and upset, Mona slaps Alison. Recovering from Mona's hit, Alison slaps her back, cutting her face and demands Mona to leave her alone before she turns and walks from the Church. She tells the Liars what happened leaving out much of the argument. The next day, Mona shows people a fabricated video of Alison hitting her intentionally. She pleads with the other girls that Mona has found a lot of ways to make them believe things were real when they're not. Emily tells Alison that maybe Mona deserved the slap, but Alison went out of her way to lie to them, again. After discovering who died in her place, she and the girls get a new message from "A" after Toby's house explodes.
The Liars' cell phones are beeping and ringing with an incoming text message, and Alison says that it is from A, and when Ezra asks what it says, Aria reads it out loud, "Did you miss me, bitches. -A". A second explosion inside the Cavanaugh house occurs leaving Alison and the others ducking for cover. In Emily's bedroom, Alison wonders if the text message they received means they were wrong about Shana, and Aria comments that 'A' is alive and knows that she killed Shana. In the school cafeteria, Alison, Hanna and Emily meet up with Spencer and Aria, and seeing Emily looking uneasy, Aria asks if she's okay, only for Alison to say that Emily practically jumped out of her skin when somebody dropped their lunch tray. Getting a text message, Alison is shocked, and shows the girls the snapchat video she received of Jessica being buried in the Hastings backyard, along with a message - "I buried your mom the same way I watched her bury you. -A", before the content automatically deletes after a few short seconds. Alison begins to consider running away again. Later, she is attacked in her home by "A" but manages to be rescued by Emily. In Emily's bedroom, she gets a text from "A" informing her that she's not safe where ever she goes.
She invited to a dinner with Emily and her mom and forces herself to go. When she talks to Caleb, he is not easily won over by he because of her past, comparing her to a tornado. She tells Hanna that boys like Caleb can be trouble even when they don't mean to be. At the dining table, Pam mentions a deal on the replacement windows, and explains to Alison that is the second set of windows they have brought this year, so they received a bad luck discount. Alison says that she could use one of those, and Emily says they all could. When Hanna says she thinks people make their own luck, Alison tells her that maybe she’s right, “maybe we do set ourselves up for bad things”. She said that she's ashamed of what happened to her, but Pam tell her not to be. She has some very special friends, and Alison states her she knows, before reaching out for Emily’s hand. When Hanna tells Alison that she’s the special one, and there’s nobody else like her, Alison just looks at her, not saying a word. Standing up from the table, Alison looks from Emily to Hanna, before grabbing Emily’s plate and walking from the dining room. Later, Alison is seen on Spencer’s security camera footage in the Hastings’ backyard, but it is unclear as to where she was going, or what she was doing.
At Rosewood High, Alison is being interviewed by Linda Tanner where she asks Alison to clarify that she hadn’t spoken to Shana since before her abduction, and Alison tells her that she hadn’t spoken to anyone and did she ever try to contact her. She denies trying to contact her. Meanwhile, she asks to stay with Hanna while her dad is away to which the latter agrees. She claims that some was watching her last night. Later, someone tries to break into Hanna's house and the police are called. Ashley stand up for her when it seems that Tanner is treating her like a criminal. As she is packing, she confesses to Emily and Spencer that the pertrator as Noel Kahn in order to get Hanna's mom to stop questioning her about what happened to her. When Spencer asks why she would do that, Alison poses, “well it worked, didn’t it?”
Alison is putting some clothes away in Hanna’s wardrobe when Emily asks her why Noel would help her break into the Marin house, before Spencer asks how he would have explained himself if he was caught. Turning around, Alison tells Spencer’s she “a little loud”, to which Spencer comments that Alison is a little crazy. When she tries to talk to Hanna about last night, Hanna claims she doesn't need Alison's help and that her stupid stunts affect a lot of people. When talking to Jenna, she asks how did turn Shana against her. Jenna tells her that Alison did it herself. Later, Ashley takes Alison to the police station where the cops claim to have her kidnapper and need Alison to identify him. Walking into an observation room, Alison watches as Lieutenant Tanner questions the man they have in custody. As Alison and Ashley listen to the man confess to kidnapping Alison.
In an office at the Rosewood Police Department, Alison is looking at Cyrus Petrillo’s mug shot when Kenneth walks in. As Kenneth asks Alison if that’s the man who hurt her, Alison says that she doesn’t know. Kenneth asks Alison if that’s him, if that’s the man who hurt her, and turning to face her father, Alison tells him she doesn’t know. However, the girls realize that the man is hired by Alison to be a pawn so they could follow him to "A." She knows Cyrus as she was a former lover of hers while she was on the run. He gave her the scar on her thigh. She finds him stealing her bag and she attacks him, but he pulls out a knife and stabs her. When Tanner takes her and Kenneth to a basement where she breaks down when she recalls her attack. After Cyrus leaves the station, Alison meets up with him as Vivian Darkbloom. Reaching into her jacket pocket, she give him a plane ticket telling him that this is his one chance to start over. Cyrus turns back to her and questions the way she’s used her chance. Alison watches as he gets into his car and drives away.
In an interrogation room at the Rosewood Police Department, Alison is getting hooked up to a polygraph test. The man conducting the test tells her that he’s going to ask her a series of questions that they know are true, then he’ll ask her questions that they don’t know. The interviewer asks Alison who else was in the barn that night, and Alison says, “Aria Montgomery, Hanna Marin, and Emily Fields”. When asked if they were all still asleep when Alison left the barn, Alison answers, “yes”. The then conductor asks where Alison last saw Spencer Hastings. When Spencer's loyalty to her is brought up, the interviewer asks what would Spencer be willing to do to prove loyalty, hinting at Bethany Young's murder. Emily and her talk and she eventually discovers the girls belief that she is "A." Betrayed she leaves Emily's house and gets into a Volkswagen Beetle with Cindy and Mindy and drives off. Later, she watches the cops at Mona's house when they announce Mona was murdered. With a coy smile, Alison turns and leaves the scene.
At the Masquerade Ice Ball, she uses Cindy and Mindy to throw the Liars off while she meets with CeCe. During this time, she is visited by the ghosts of her mother and Mona where they show her how she came to the person she was. Mona, as a ghost, eventually shows up and shows her a past where she, as child, first learns how to lie. Little Alison finds two yellow dresses and Jessica helps rehearse a lie to tell her father out of fear that he would leave them. Mona comments that that’s when the monster was born. When Mona returns, the ghost tells her that ignoring her won't make her go away but make her mad. She then shows Alison a funeral where she herself is the one in the casket and no one is there to mourn her. Jessica. as The Black Widow tell her that they would be coming for her soon. As spirits start to fly around the Church, Alison asks if she’s going to hell. Jessica turns back with a tear running down her face, and backing away, Alison runs towards the Church doors, unable to get out, “No! Please! Let me out! Mona!” Alison is now in her room where Mona tells her it's Christmas and promises that she doesn’t want to miss it. As Mona disappears, Alison looks around her bedroom. That night, Alison watches The Lairs, Paige, Ezra, and Toby enjoy Christmas dinner. Disillusioned, Alison turns and starts to walk away.
Outside of the Rosewood Church, Alison walks up to Leona Vanderwaal, who is watching Mona’s coffin in the back of a hearse. Alison tells Leona that she came to pay her respects, but Leona slaps her and screams at her asking her where Mona's body is, before Hanna walks up to Leona and guides her away. Holding her cheek, Alison looks around the stunned crowd. Everyone including Jason begins to suspect that she killed Mona. When Jason questions her on her whereabouts Thanksgiving Day, Alison claims that she's being framed. While walking down the street, she exchanges words with Carla Grunwald who tells Alison that she's in her prayers before leaving. Alison hurries into the DiLaurentis living room with a bag on her back. As police lights and sirens start to flash. Attempting to run, Alison is shoved backwards by the Liars. She claims "A" set her up so that she couldn't protect them, claiming that they will be next. Lt. Tanner shows and has her arrested. Her final words to the girls are “don’t say I didn’t warn you”. In a women’s correctional centre, Alison lies awake, tossing and turning.
Alison, having been transferred to Chester County Women’s Correctional Facility, is led to a holding bench and chained in place. Looking up when Toby stops by her, Alison tells him that they, as in the girls, need to see her. They can’t keep ignoring me”. Toby is unsympathetic and as he leaves, Alison questions if he’s forgotten what it feels like to “be in a cage for something you didn’t do”. Alison asks if he remembers how that felt, and Toby tells her he does, but he also remembers whose words put him in that cage. In her cell, Alison is visited by Hanna. Alison mentions that she could have thrown all the girls under the bus, “but I didn’t. I kept her mouth shut”. Just as Hanna leaves, she reveals that she was meeting Cyrus that day only discover that "A" set her up when Mona went missing and she had no alibi. Later, Alison gets up when she is delivered a new jumpsuit. Taking the jumpsuit, Alison waits until the inmate moves on, before pulling out a note from the top pocket, “Your friends will see you soon”.
Being led into a visitation room, Alison stares in at Emily, Spencer and Aria through a glass window. Alison listens as Emily says that Mike was scared to say anything as he still thought Mona was alive and didn’t want to put her in danger. She is told of Mona's plan to catch and that it backfired. A guard enters the room, telling them all that their visiting time is over. When Aria walks back over to her, Alison tells Aria that she’s going to have to tell her lawyers about Mike, and Aria pleads with her not to do that. When Alison comments that Mike’s testimony may be the only thing to save her, Aria asks if she can hold off, and wait to see if she can find Cyrus as he may be able to lead her to ‘A’. Alison is led in to the visitation room, and on seeing Veronica, Alison asks what she is doing here. Veronica says that she wants to know why her daughter and her friends are visiting Alison all of a sudden. Alison says that that’s why she wants to take the stand, “I want to tell my side of the story”, but her lawyers won’t let her. Veronica comments she could say the wrong thing and wind up incriminating herself. As Alison says that she can’t just sit here quietly while someone gets up there and makes her look like a murderer, Veronica reminds her that she’s told so many lies, people know that now. Alison asks her to be her coach for the trial. Pushing a clothes bin into the laundry room, Alison notices the words ‘told everything’ under where she’d previously written ‘Mona’ in the dust on the table. In her cell, Alison finds a soda can, and taking off the lid, she finds a small blonde doll and a note, “You’re already over a barrel, wanna be in one, too? –A”. When Hanna comes to visit her, Alison expresses regret over how she treated the girls. When when they stopped listening to her, she found new people who would. Alison adds that being in jail, “no one listens to me”. She never realized how bad that felt to be on the other side of that, Alison fights back tears, “so I’m sorry”.
Sitting in the visitation room, Alison listens as Rebecca, her lawyer, explains that Veronica Hastings reviewed Alison’s case and she agrees that it’s not a good idea for Alison to take the stand. Alison questions how not telling the truth is a good idea, and when Rebecca tells her that she doesn’t have anyone to back up her story, Alison says that Cyrus Petrillo asked her to meet him at the time of the murder, “he set me up”. Rebecca points out that Alison also told the police that Cyrus kidnapped her, and if she admits that lie, no jury will believe anything else she says. Alison comments that there’s someone else who could testify to her being set up. She also learns that Hanna is suspected as being her accomplice. Walking through Chester Country Women’s Correctional, Alison finds her cell ransacked. Pulling her overturn mattress down from the wall, Alison finds a message scribed on the wall, “TAKE THE PLEA”. In the laundry room, Alison is ironing a jumpsuit and is attacked by an unknown person. At the phones, Alison calls Rebecca. Alison wonders that if she agrees to what Rebecca mentioned earlier, could she promise that the D.A will move her somewhere safer than this. When Veronica visits her, she encourages her to continue her fight for if she takes the plea, Hanna is behind bars for something she didn't do. When Rebecca present her the plea deal, Alison decides to not take it. Later, she sees Hanna walk in a jumpsuit being led to her cell.
In a visitation room, Alison watches Rebecca point out where they and the prosecution will be sitting when the trial begins. As Rebecca tells Alison to not be afraid to look at the jury, they don’t want them to think Alison has anything to hide, Kenneth says he doesn’t like the idea of twelve strangers off the street deciding what happens to his daughter, to which Rebecca tells him that it’s the American way. She calls Emily to see if she will be at the trial which the latter says yes. In the courtroom, the prosecutor, Douglas Sirk, goes through his opening statement, asking the jury to remember high school and how people like Alison make that experience a fight for survival. Sirk says her tale of escape is a lie and that Mona Vanderwaal knew the truth which led to her death. In the laundry room, Alison pushes a trolley of jumpsuits over to the dryers and receives now dries ones from inside. Hanna walks in, the two girls lock eyes. She tells her of how Mona was sending her mock tributes that stopped when Mona was killed. Later, Alison sits across from Jason in a visitation room. Jason comments that they’re quite the pair, Alison mentions that lying is a one way street, “it’s kind of like those signs in parking lots, ‘backing up causes severe tyre damage’”. Jason wonders what Alison’s lawyer thinks, and Alison tells him that Rebecca remains confident. When Jason asks if there’s anything he can do, Alison tells him that he had the right idea a long time ago, “get out”. Alison tells Jason to just leave and do it now, and after a short pause, Jason mentions that he believes her. Jason adds that he’s believed her since that night at the house when she tried to get away, he saw it in her face, she didn’t kill anyone. Alison then admits that while she didn’t kill anyone, she did let a lot of things happen that she shouldn’t of.
After court, Emily, Spencer, and Aria have a conference call with Alison and Hanna. Hanna is on one phone while Alison is on another. The girls fill Alison in about Leslie. Aria thinks that Leslie may be another one of A’s traps, but Hanna believes that Leslie cared about Mona. The girls tell Alison about the cryptic note they found in Mona’s room. The girls are worried as they are running out of time and have no clue on how to proceed as Alison has no alibi. Alison states that according to her lawyer, going after a possible witness is a waste of time. She tells the girls that while she was waiting for Cyrus on the playground, she heard someone there and saw their jacket. She thought it was ‘A’ and panicked and ran away. Hanna and Alison’s calls get cut off as their time is up. Meanwhile, Alison and Hanna are in the laundry room. She and Alison try to talk about Kendra but the guards won’t give them a second alone. So, Hanna slams her hand in the dryer and Alison burns herself with an iron so that they can go to the infirmary together. Rebecca visits Alison in the infirmary. Alison tells her that what happened to her was an accident. Hanna comes out of the infirmary. Alison passes Hanna a note and Rebecca sees this. She lectures them they are on trial for murder, not in homeroom detention. In court, the prosecution unravels any defense the defense has making it impossible to not convict Alison. After deliberation, the jury returns and pronounces Alison guilty of murder in the first degree. Alison is handcuffed and taken into custody.
Chained, Alison is led into the visitation room where Peter and Veronica Hastings wait for her. When she learns that the Liars have been kidnapped, she finally reveals to them that it was "A." She explains to them that Mona started the game again at Radley but someone else took control of the game from Mona and mostly likely killed her mother and Mona. Peter asks why didn't they go to the police and says that "A" erases or leaves no proof for anyone to use against them. She swear that she's telling the truth this time. Alison listens as Peter questions why she’s being honest now, before telling him that she’s going to spend the rest of her life in jail, “I don’t have anything else to lose. But you do”.
Alison is released from prison when it's revealed the Liars are kidnapped and that they were all framed. She conspires with Toby, Ezra, and Caleb to escape her police guard in order to formulate their plan to rescue the girls. It is revealed that Alison’s statement at the press conference was actually a message telling 'A' to meet her at the Kissing Rock. Alison and the guys plan to use Alison as bait to find the girls. They will follow Alison to wherever 'A' takes her, leading them to the girls. Caleb hands Alison a pair of shoes with a GPS tracker to help them follow her. At the Kissing Rock, a car has been left for her in the woods. Alison climbs into the car and the GPS begins giving out directions to her destination. She starts driving down the highway while Ezra and Caleb follow her from a safe distance. The GPS in the car leads Alison to Tyler State Park. On reaching her destination, the car conveniently runs out of gas and her phone doesn’t have any reception either. Stuck in the middle of nowhere, Alison presses the road-side assistance button, to be greeted by a male voice that tells her to open the trunk of the car. Dressed in the same outfit the night she disappeared she wonders through the woods until Caleb and Ezra find her. They find the dollhouse and rescue the girls, Mona, and Sara Harvey.
Alison talks to Spencer and tells her that her father said there is no Charles DiLaurentis. Alison asks Spencer if she wants to go to the police with her Charles theory but Spencer tells her that she doesn't want to walk into the police station with any more theories and that the cops should figure it out. Toby introduces Lorenzo Calderon to. At church, Alison spots Lorenzo. After the service is over, Alison rushes out and Lorenzo chases after her. The two have a chat about how they used to go to church when they were young, but then stopped. Alison then tells him that she has to go and runs off. Before she leaves, Lorenzo assures her that he won't tell anyone that he saw her at church. Alison asks why he thinks she doesn't want people to know she goes to church. He replies that he doesn't know why, but he does know that she doesn't want anyone knowing.
Alison runs in to Lorenzo, who is coaching a soccer youth group for boys. Lorenzo invites Alison to be the leader for the girls youth group, but Alison declines, saying that, “There are mothers in this town who wouldn't appreciate me supervising their daughters.” The girls pay Alison a visit and tell her all about Jason’s “imaginary friend” Charlie and try to convince her that her father lied to her. Alison is upset, and reminisces about how Jason always thought something was missing from the family. They decide to look through the house and try to find proof that Charlie existed. While going through the house, Alison points out to Spencer that Toby is probably back to hating Alison now that the girls are safe. Alison then talks about how nice Lorenzo is, and how Toby must’ve told him all about the not-so-nice things she’s done. It’s obvious that Alison actually likes Lorenzo, and seeing this, Spencer encourages her, telling her that she’s got a second chance at life and she shouldn’t waste it. Deep inside a jar, at the bottom, she finds a folded up picture of two little boys with Jessica. After telling Jason, the two of them confront Kenneth who finally tells them about Charles.
Alison learns that Charles was the oldest DiLaurentis Child who had mental issues who was in Radley until his death at sixteen. Kenneth later tells her that Charles tried to drown her in a tub of hot water when she was a baby. Alison finds Jason looking at a picture from when they were young in the DiLaurentis living room. Ali comments on how they were so innocent back then. She asks Jason if he is okay and Jason questions her if she would be okay if she were convinced to believe what she saw with her own eyes to be a lie. Jason says that Jessica and Kenneth made him doubt himself and how, ever since then he's always doubted himself. Alison tells him what the girls discovered and shows him Charles' Radley file. When Ali says that Aunt Carol visited Charles a lot in Radley, Jason remembers the time when he got hurt in the elevator the previous year and thought that Wilden was after him, he drove up to Aunt Carol's house for hiding from him. Jessica however turned him away but not before he heard a crash in the house. Alison asks him if he ever went back there. Jason says that he never did but he always wondered why Jessica was keeping that place even though no one was living there. Alison suggests that maybe someone, I.e. Charles, was living there.
Alison hears two police officers talking badly about her. Her father tells her that she made a bas reputation for herself and needs to own up to it. Lorenzo and Alison are sitting in the living room. They discuss plans for the church's youth group. Alison isn't sure she is the right one to guide the kids, but Lorenzo tells her he already recommended her for it because he thinks she can make a difference. Kenneth comes in and gets angry about finding Lorenzo there and kicks Lorenzo out. Alison gets a text from Hanna, telling her to come over as they found something. As Alison tries to leave, Kenneth stops her, thinking she wants to meet Lorenzo. He threatens to take her away from Rosewood if she sees Lorenzo again. Alison asks if he intends to bury her on Aunt Carol's farm with Charles.
He then drives away with Alison, to take her to a safe place. Alison looks at the birthday invitation, which Charles sent to Kenneth and realizes he is alive. She is at a hotel with her father, who doesn't allow her to leave. Alison informs Spencer about Charles' birthday invitation and Jason being determined to meet Charles. Kenneth knocks on the door, because he noticed Alison took his phone. Alison asks Spencer to talk to Jason and hangs up. She opens the door and Kenneth comes in. Alison wants to tell the police about Charles, but Kenneth disagrees, because he wants to figure out what to tell them first. Meanwhile, Alison is in front of the hotel, where Mona picks her up. Alison is thankful for driving her and Mona states she owes her more than a car ride. Even though Mona tells her not to, Alison decides to call 911 about Charles. Later, her and Jason watch a video from Charles of the one of his birthday's when they were preteens.
Alison is with Lorenzo at his apartment. She declares that nobody understands it and her father treats her like she's the threat. She claims that the only person Kenneth is opening up to about Charles is Tanner. Lorenzo understands how hard it must be for Alison and says he wished he would have stopped Charles. He suggests calling a friend on Tanner's team to get some answers, but Alison tells him he doesn't have to. She later folds his laundry while he is sleeping on the couch. When she is about to leave, she sees Lorenzo's access card to the police department and after a short hesitation, she takes it with her. Alison walks into Tanner's office, which is filled with information about Charles and all of the unsolved murders of the last years. Tanner catches her in the act. She gets back to Lorenzo's apartment, where he confronts her about breaking into the police department and tries his best to understand why she did it. After Lorenzo wonders why she didn't ask him, she states that he would have said no, and she would have done it anyway.
The Liars are in The Brew discussing the fact that they won't be attending prom. Alison excuses herself to use the restroom, but receives a text from Charles: "Better be at prom. It's our last chance to dance. Come alone. xo Charles". Alison answers a call from a blocked ID and, after some silence, says "Charles? Is that you?" then says that she can't go to the school prom. Ali then says "Please. Charles, talk to me!" and the call is disconnected. She hears a noise outside and we see a hooded figure move past her window. Ali walks over to her window, but hooded figure is gone. Later, Alison walking towards the barn in her prom dress; she turns around and waves to her friends' moms as a figure in a red coat and a mask looks on from behind some bushes. Once their backs are turned, Ali runs into the bushes and the figure follows her. She arrives at the prom and eventually is captured by Charles who takes off the hood. Alison is shocked at what she sees.
Posthumous Video FootageBefore disappearing, Alison had met with Ian at "The Kissing Rock," where they had made a makeout-tape. In the footage shown to the girls by Agent Cooper in "Know Your Frenemies," Alison teases Ian, "I know you want to kiss me." Ian replies, "Come closer." A struggle appears to occur, and the camera falls to the ground, losing focus on the other two. Then, Alison's hand falls into view of the camera; her hand grabs onto some dirt and leaves, before going limp. She falls down and you can only see her hand... it's not moving. But a bit later, in The Devil You Know, it is seen that afterwards she grabs at the dirt then lets go of it and laughs, thanks Ian for coming, and then Ian puts his jacket back on and walks away. The girls had originally taken this video as proof that Ian murdered Alison, but upon seeing the additional footage, courtesy of "A," they are left to wonder. In some video footage from the same night in "The Blond Leading the Blind," Ian claimed to Garrett and Jenna that he met Alison at "The Kissing Rock" in order to obtain the N.A.T. Club videos that she had taken. Unbeknownst to him, Alison had already stored the videos away and gave Emily the key.

Alison was the ring-leader of her group of friends, which consisted of Hanna, Aria, Spencer and Emily. Alison had hated Mona, who was dorky at the time and constantly made fun of her. When Aria thought about being nice to her and waiting for her, Alison convinces her not to. Alison treated Hanna like her lackey, Emily is hinted to be more than a friend, and Spencer and Alison often clashed with one another. She also made fun of Lucas a lot and called him a hermaphrodite, or "Hermie," which led to Lucas smashing up her memorial. She did not like Jenna and referred to her as "Jenna the Jerk", stating that she found her creepy. Alison had ultimate power over her friends, getting them to do what she wanted despite their objections. No one ever stood up to her, except Spencer although the latter backed down almost immediately when Ali spoke. Though she was cruel and nasty to them, it is hinted multiple times she truly and deeply cared for the girls.
Aria Montgomery (see "Alia") - Alison has a more neutral relationship with Aria than the other three girls. She seems to have the loosest connection to Aria, compared to the other three girls. They seem to get along and have a casual friendship. They don't get into many arguments, nor does Alison treat Aria like a lackey. However, Aria does follow Alison's suggestions most of the time. Alison mostly lets Aria do her own thing and does not often get involved in her personal life, except when she threatened her father about the affair, and would sometimes use it to get Aria to do what she wants. They are both naturally independent and obsessed with their own sophistication.
Emily Fields (see "Emison") - It is seen multiple times throughout the series that Emily was closest to Alison than rest of the group. In "The Perfect Storm," we learn Ali and Emily had a relationship that was more than a friendship. She wrote Ali a love note and loved her more than a friend. Alison was leading Emily on though and had no real feelings for her than friendship. However, in "Monsters in the End," she chose to give Emily the snow globe with the hidden key. Alison tells her to keep it safe because it's "a lot more valuable than it looks." This might mean that Alison trusts Emily more than the other girls. Alison also tells her that Emily is the only one that really "understands her". The she can be honest with. When Emily was on the brink of death In "Over My Dead Body," she wakes up and she sees Alison. Alison tells her that she misses her the most and was her favorite, and that no one loved her as much as Emily did. She also questions if she really wants to be free of "A," and also questions whether she wants to stay in the position she is in or join her. Emily then asks if she knows who "A" is. Alison responds that of course she knows. After Emily asks her to tell her, she states she can't because "Two can only keep a secret if one of them is dead." Alison then gently kisses her, which makes Emily believe that she is alive. Out of the rest of the girls, Alison said that Emily is the only one who truly understands her and with whom she could completely be honest. In "Miss Me x 100," Alison confesses to Emily that she has feelings for her, and that Emily's kisses weren't just for practice as she lead her to believe. Emily stayed with Alison when she was home alone; Emily kissed Alison, who returned the kiss. In "The DArkest Knight" Alison reveals to Emily she is pregnant. Emily then spends the night with Alison, and Alison attempts to kiss Emily while they sit on the couch watching a movie. Emily initially pulls back, saying that Alison is "really vulnerable right now." Alison responds by saying "That's not why, I promise." Alison leans in to kiss Emily again and Emily accepts the kiss.The two begin to make out.
Hanna Marin (see "Halison") - Alison gave Hanna the name "Hefty Hanna", mocking her weight. Despite being the sweetest of the bunch, Hanna was often cruelly mocked and teased by Alison. This is seen in "Know Your Frenemies" as well as in "Never Letting Go" and other episodes. In "Know Your Frenemies" we also find that Alison even convinces Hanna to throw up to lose weight, therefore starting an eating disorder for Hanna. She also convinces Hanna not to eat in "Pilot" with the excuse she is being a friend. She is very mean to her during "To Kill a Mocking Girl" and calls her a wannabe and other rude words leaving Hanna in tears, and she doesn't stop until Aria tells her to. Alison tells Hanna that she didn't mean it and that she was freaked out about "The Jenna Thing." Alison also mentioned in her diary that she almost convinced 'Hefty Hanna' to shave her head. Out of the four girls, Alison seems to be the meanest to Hanna because she was jealous of Hanna's good looks; she knew that Hanna had the potential to take her place as the most popular girl at Rosewood high, if she lost weight and gained confidence. She usually leaves Emily and Hanna feeling bad about themselves. Hanna also has the most hallucinations about Ali, such as in the hospital and with her therapist. This could be because she never had the guts to stand up to Alison's teasing and subconsciously feels upset about never doing so (although she once tried to get Ali to stop bullying Lucas, but ultimately backed down). Other than the times she was cruel to Hanna, they were very good friends and Ali was nice to her.
Spencer Hastings (see "Spalison") - Her relationship with Spencer is very different. Spencer and her were always fighting, and trying to out-do each other. She usually leaves Spencer annoyed with her and Ali distressed because Spencer is the only one of the four girls who could ever stand up to Ali, which fact first comes apparent in "Pilot", when they have their argument in Spencer's house, the night of Ali's disappearance. There, Ali threatens to tell Melissa about Spencer's kissing Ian or else she will. Spencer yells at her that if she should so say one word to her, she'll tell everyone the truth about "The Jenna Thing." Also in "If At First You Don't Succeed, Lie, Lie Again" she is again seen pressuring Spencer to tell her sister about Ian. (This is hypocritical considering the fact that she was secretly dating Ian, and Alison probably did it in order to make Spencer look bad while getting Ian to herself.) Spencer tells Alison that she is sick of her games, and Alison is dead to her already. Alison appears distraught, then Alison leaves angrily, and Spencer follows her. Spencer is the most like Alison: smart, determined, sophisticated, and will do just about anything to be the best.
FamilyJessica DiLaurentis - Alison often threw tantrums to get what she wanted from her mother Jessica, as seen in "Turn of the Shoe." She would hold her breath until Jessica gave in, a trick Alison perfected at the age of 5 to get what she wanted. Jessica also took notice of CeCe Drake's growing bad influence over Alison and tried to put a stop to it. Alison seemed to challenge her mother's authority somewhat in order to do the things she wanted. In "A is for Answers," Alison reveals that Jessica is the person who buried her alive and knows who her attempted murderer is. Jessica covered for this person until her death. Shana Fring also mentions in "EscApe From New York" that Jessica was afraid of Alison. When Jessica's body was found by Pepe, Ali stood in the background wearing a hoodie to prevent her from being seen and cried.
Jason DiLaurentis (see "Jalison") - Jason is Alison's half-brother, due to their Mothers cheating on their Father with Peter Hastings, Jason grew up a DiLaurentis, but is biologically still a Hastings. She did not have such a great relationship with her brother Jason, due to his drug addiction and their mutual disrespect of each other's boundaries. Both had no qualms going into each other's room, stealing and breaking each other's belongings. Some glimpses of that were seen in "The Goodbye Look," "My Name Is Trouble," and "Surface Tension." In one instance, Alison had fled one of her brother's house parties in tears, blaming her distress on Jason and his friends' invasiveness in her room, but left the particulars vague.
Kenneth DiLaurentis - Alison's relationship with her father Kenneth is indeterminate. Kenneth is stern and intimidating, and seems to impose his authority on Jason more than Alison. He seems oblivious to the things that Alison has done. In "Whirly Girlie," Kenneth comes back to Rosewood when he finds out that Alison is alive. When Alison comes home, he is very protective of her and wouldn't let her leave the house. Kenneth promises Alison that he will never let her out of his sight again. Alison appears to care deeply for her father, more so than she does about her mother or brother. when she attempts to run away in Run, Ali, Run, she is upset when her father is not home as she was hoping to say goodbye to him before she left.
Alison's relationship with her sister is one that takes time, she finds out that her sister is transgender and has been the one torturing her friends in Game Over, Charles, the Season 6A Finale. Charlotte explains everything to Alison and the Liars, Charlotte begins to live in Rosewood after the Season 6A Finale, Alison and Jason stay behind to take care of her and to make sure she's okay. (Charlotte DiLaurentis, was only known to The Liars as CeCe Drake so that she could watch over them and be 'A')
Duncan Albert - Alison had a some sort of secret friendship or relationship with Duncan before her death.
Duncan saw a side of her she didn't show other people. It seemed that even though using a fake name, Alison was much more honest and real with him. It seemed like an indication of what a better person the adult Ali would have been like, but never got a chance to happen. Duncan met Alison/Vivian in a book store in Brookhaven. Vivian often spoke about her four friends to Duncan, which mean she trusted him to a certain extent. He reveals that he and Vivian met up at a place near Brookhaven quite often during the summer Alison disappeared. He also reveals that he knew Vivian's real name was Alison but was unaware of her death until Aria told him. During the friendship Duncan often took Alison up to his helicopter. He explains that he and Alison used to fly often and that she used to feel free, safe, and in control. He also mentions that he might have been in love with Alison.CeCe Drake (see "Cali") - CeCe dated Jason, and sometimes hung out with Alison, but CeCe was very similar to Alison's attitude. CeCe taught Alison some of the wicked stuff she knew. And also Alison told CeCe some secrets about the girls. CeCe and Alison had more of a big sister, little sister relationship. Mrs DiLaurentis did not like Cece's influence on Alison. In one scene she is seen telling Alison they're friendship is "toxic," to which Ali responds "so are a lot of things." In Season 4, it's revealed CeCe and Alison had an unhealthy relationship. Mrs. DiLaurentis says CeCe would pose as Alison. CeCe hated Alison for getting her kicked out of college. CeCe assumed the other girls were in on it to, so she joined The "A" Team to torture them; however it is revealed that she killed Darren Wilden to protect Alison and therefore not on the A-Team.
Paige McCullers - When CeCe sees Paige and Emily together, she reveals to Spencer about Paige's violent past with Alison. In a flashback at one the liar's sleepovers they are trading clothes and Aria points out the bruises on Alison's back she simply replies "Oh Pigskin gave them to me" they asked who Pigskin is but Alison brushes it off, as Alison does with everyone. Alison was going to tell everyone that Paige is a lesbian. Alison had an enmity of sorts against Paige. Apparently, Alison once received a kick to the back in soccer from Paige after she annoyed her too much, but swore vengeance upon "Pigskin." Somehow aware of Paige's secret pining for Emily, Alison forged love letters in Emily's name and sent them to Paige, eventually leading to Alison intercepting one of Paige's own letters, which Alison used to blackmail Paige into becoming her "property." CeCe speculates that Alison might have been afraid of Paige. In "Miss Me x 100," Alison tries to make amends with Paige and apologizes for the way she treated her, but Paige doesn't accept her apology, saying that Alison is still a horrible person. In "The DArkest Knight" Emily invites Paige to Spencer's house while they are waiting for the police to find Hanna. Alison is visibly uncomfortable to be in the same room as Paige, and even asks Emily why she invited her saying "she has nothing to do with this" and "I just think it's a little pathetic that she's using this to get close to you" When Paige comforts Emily, Alison says "Ugh, i'm gonna be sick" and leaves the room. Later, Paige comes to drop off job application forms for Emily and gets upset seeing that Emily slept at Alison's house. Paige says that Alison is trying to drive them apart, and says that Emily should call her when she "decides to cut the strings" with Alison.
"Autopsy" and "Death"
Alison seemingly died of suffocation, which is revealed in "The Jenna Thing" and mentioned once again in "For Whom the Bell Tolls." More information on her death is revealed in "Save the Date:" Alison had been hit from behind or was running away when she had been hit on the head. The wound had come from a curved, blunt object (which Spencer believes to be her old field hockey stick). However, the impact had not killed her immediately. The autopsy found her lungs to be filled with dirt, implying that she had been inhaling dirt in the last moments before her death. This basically means her assailant had struck her, either knocking her unconscious or otherwise paralyzing her defenses, and proceeded to bury her alive. We later come to find in "Over My Dead Body" that the "curved, blunt object" actually wasn't a field hockey stick, but a shovel. Alison was buried by the same object that damaged her head. In "It Happened 'That Night'," Alison's body is stolen from her grave. In "This Is A Dark Ride " Alison's body is found in the ice cooler at the Halloween Ghost Train Party, after Toby and Noel fight, knocking the Cooler down, showing a black leather bag. Also shown the same episode was a flashback of her hand coming out of the ground, revealing she may have escaped. It was revealed in a flashback in "A DAngerous GAme" that someone helped pull Ali out of the ground. We can see a hand reaching down and grabbing Ali's. In Now You See Me, Now You Don't, it is revealed that Carla Grunwald was the hand who pulled her out, meaning Alison did not die, and is still alive, hiding from A. Whose body it really is remains unknown. Alison was hit with a shovel and buried alive, but survived. Someone else was also hit with a shovel and buried alive, but died. In A is for Answers, it's revealed that Alison was not hit over the head with a shovel, but a large stone. Her mother saw whoever hit her and buried her alive (thinking she was dead) in order to protect the person who did it.
In Miss Me x 100 it's revealed a girl named Bethany Young, who was a 17 year old patient at the Radley, escaped from the mental hospital the night Ali went missing, and is the one in Alison's grave, as well as the body who was found in the Pilot. In Taking This One to the Grave, it is revealed Ali's mom was having an affair with Bethany's father, and Alison knew about this and lured Bethany to Rosewood the night she "died", possibly in order to kill her. Alison acted as if she did not know who Bethany was, and is now possibly not hiding from "A", but is "A".
- She, along with the other Liars, blinded Jenna Marshall with a stink-bomb in a prank intended for Toby Cavanaugh. However, in the "The First Secret," it is shown that Ali strongly disliked Jenna seemingly because Jenna refused to be intimidated by Ali and refused to join her group of friends, saying that she'd prefer to pick her own friends. This could be hinting that Jenna really was Ali's intended target with the stink-bomb, and blinding her was no accident at all. Another possibility could be that she was forced by "A" to pull the prank, which would explain her insistence on going through with it, and her obvious shock at seeing Jenna inside, assuming that was not part of the deal.
- Ali displays sociopathic qualities: controlling, paranoid, charming, seductive, dominant, incapable of remorse, and extremely intelligent. Though at times, Ali does seem to display real emotion.

- She was kissed by Emily Fields, but later informed her that she likes boys and would only kiss her for practice for the real thing. In "Over My Dead Body," it is implied that Alison may have actually loved Emily as she kissed Emily after saving her, or else that is simply Emily's wishful thinking and Alison's manipulative nature. Alison comes back after revealing herself alive and tells Emily that those kisses weren't just for practice; and they kiss. However, when Alison is revealed to possibly be "A", it is clear she did that to get Emily on her side.

Alison: Friends share secrets. That's what keeps us close.
Alison: It's immortality, my darlings.
Hanna [in hallucination]: Please, just tell me the truth.
Alison: It won't make any difference, darling.
Alison: You think the truth is some big shiny disco ball of purity? Then go ahead and try it. Be honest. See what it gets you. Telling the truth to the wrong person at the wrong time is how I ended up where I am. Take it from me, you're always better off with a really good lie.
