The First Secret (chronologically)
Jenna Marshall is a recurring character on Pretty Little Liars, and the younger stepsister of Toby Cavanaugh. She was the victim of a prank orchestrated by Alison DiLaurentis that resulted in her becoming blind. They refer to that incident as "The Jenna Thing". She is portrayed by Tammin Sursok.
In October 2008, Jenna moved to Rosewood after her mother married Toby's father. She quickly became popular at Rosewood High School. Alison invited her to join her group of friends, but she declined. This led to a long-term rivalry between the two, as Jenna is a very aggressive and manipulative person. She forced her step-brother, Toby, into a sexual relationship with her and threatened to accuse him of forcing himself on her.
After being accidentally blinded by a stink bomb set up in Toby's garage by Alison and her friends, Jenna developed a hatred and grudge against all of them. Jenna seems to have been involved with the N.A.T. Club before Alison went missing. She was not sorry for Alison's passing and has continued to keep The Liars on her radar to assure they won't reveal her secret.
In Season 2, Jenna got an eye surgery and was fully able to see throughout the third season. However, going into Season 4, the operation proved to only have temporary effects as she began to lose her sight again. She used to date the popular jock Noel Kahn and used him to regain her popularity in school.
While she was still blind, Jenna was made to believe that Garrett, whom she dated, killed Alison. Throughout the first three seasons, Jenna thought she knew how Alison was killed. However, it was incorrect. Jenna has almost been murdered twice: once in Season 2 by being lured to and locked in a burning house and again in Season 4, after being knocked unconscious and left in a lake to drown by Charlotte DiLaurentis.
Jenna walks in the Apple Rose Grille while the liars are there. When she sits down, they silently get up and leave.
Aria invites Jenna to sit with her and the others in the school cafeteria. It is an awkward lunch, as Jenna purposefully frightens the girls makes reference to the group's changed dynamic since Alison's death. Jenna tells them that Alison came to visit her while she was in the hospital. She says that everyone misunderstood Alison but that she knew exactly who Alison was. The girls are silent as they flashback to the fateful events of that night. At one point, Jenna breaks the silence by picking up Spencer's beeping phone, when she receives a text, with Spencer paranoid to receive a text from "A" with Jenna in such close proximity. Obviously, no one found out about "The Jenna Thing," but with Toby knowing, they could never be sure about when the secret was going to slip and if "A" would ever play that card.
When Spencer is out for a run she sees Jenna sitting on a bench. Jenna is using a phone for the blind and says "Send text now." She turns and looks at where Spencer is standing.
Jenna walks into school with Toby in tow.
Jenna is walking down the hallway while the girls are whispering to each other. She comments such as "Whisper, whisper, whisper. Almost feels like Alison's still here,"
Later when Emily comes to thank Toby for helping her with Ben, Jenna is present which is unknown to Emily. After Emily leaves Jenna questions Toby about the reason why Emily is thanking him but he tells her it isn't what she's thinking.
Jenna is seen by Hanna on her way to work at Dr Ackard's office. Jenna enters the elevator and puts on her lipstick. SHe asks Hanna if she likes the color. It is unknown if Jenna knew she was talking to Hanna.
After the homecoming dance, when Emily is home from being hospitalized, Jenna visits Emily with her seeing eye dog, Shadow. She comes under the guise of being sympathetic to Emily's plight, bringing cookies to bed-ridden Emily (which Emily does sample, despite Spencer's distrust towards them later). She knows that Toby's psychological profile is missing because the cops went looking for it, and knows that the Liars have the file, having overheard them talking about it at Homecoming. She wants Emily to return the file to her, so that she can protect her secret of having forced her step-brother into a sexual relationship. Emily is open to fulfilling Jenna's request, as she feels partially responsible for Jenna's accident, something Jenna does not fail to mention repeatedly. Emily tries to get the file back, but cannot contact the girls while her mother is around. Aria throws the file into the river. (It seems the file makes its way into "A's" hands anyway, when a figure is seen gingerly retrieving the pages from the water.) When Jenna asks for the file after Emily is back at Rosewood High, Emily vaguely tells her that the file is gone, and Jenna is put off, being put in the position where she is forced to trust Emily.Emily, she is very jealous. Jenna tells Toby she turned him in to the police so he would come home and continue their relationship. Jenna also proves she can be slightly abusive and controlling, as she slaps Toby when he tells her he will "never touch her like that again.", and asks who he thinks he's talking to.
When Toby's house arrest bracelet is to be removed, she hails a taxi cab, so the two can ride there together. She is very upset when he declines her offer, choosing to go with Spencer in her car, rather than with her.
With Mr. Fitz as her guide, Jenna writes an essay to be submitted to an essay contest with vague references to the event that blinded her. The essay centers around a blind girl that senses more than seeing people do. It seems from the essay that the incident that blinded her was not an accident, although it leads Mr. Fitz to believe her brother is guilty, not the girls. Ezra is fascinated by the story and believes it has a winning chance. At the end of the episode, Aria confides to Mr. Fitz about who the real perpetrators were. Jenna makes references to Aria's romantic relationship with Mr. Fitz, scaring Aria, because it is unclear how she knows about the couple.
Hollis College, alongside Aria. Aria pretends to be Anita, so as to hide her identity from Jenna. It is interesting to note that when she was talking to Aria, thinking she is Anita, she shows a much sadder and more vulnerable side then she usually does. She has made a beautiful pottery piece, but is frustrated that she cannot see anything, not even the shadows it produces when lit. Aria tries to comfort her and praise her work, but when Jenna discovers that it was Aria, she goes ballistic, screaming at her to get out. Jenna's House in his car. It could go either way, considering Garrett's parents live across the street. However, Garrett heads for Jenna's place, and the girls follow to watch. Inside, Jenna removes her robe to reveal the black lace lingerie she was seen buying in an earlier episode. She removes her glasses, and the two start to kiss passionately. Garrett and Jenna do a lot of spying together in Garrett's sports car. There, they constantly refer to "The Jason Thing," an ill-defined incident that may or may not be linked to Alison's death. When Jason kisses Aria, Jenna expresses her fear that the two will hook up, and Jason will reveal his secret to Aria. The latest development is the possibility that Jenna will have a cornea replacement, which means that she may regain her vision at some point in the near future. Toby fills Spencer in on the details of the matter after she overhears Jenna discussing the possibility with a nurse, while all the girls are in Rosewood Community Hospital.
Outside on the porch, a sulky Ali jealously calls Jenna a slut. Back in the party, Emily is seen slow-dancing with Ben on the dance floor. Jenna is seductively dancing nearby, and Emily ogles appreciatively at her curves and moves. Alison turns her eyes from one to the other, approaches Emily, and alludes to her secret sexual orientation.
Jenna has yet to be seen during the second half of Season 2. She stayed home from school, but seems to have attended the swim meet after school.
She argues with Garrett over the phone and refuses to let him in the house. Garrett says it was a mistake for them to bring a third person in on their plan. Later, she leaves for her eye surgery in Boston without Garrett.
It is revealed that Jenna went to "Kristen August Rehabilitation Center For The Blind" after the Jenna Thing happened.Noel. They decide to go to Rive Gauche to cheer up. Jenna overhears this and in the evening, she is seen talking to Noel very intimately in Rive Gauche. Jason DiLaurentis and then sets it on fire, trapping Jenna inside with the intent to murder her. She is rescued by Hanna, who happened to be near the DiLaurentis household. She goes to the hospital and has to stay there under observation. This marks the first time in the series that Jenna seems to be frightened. She asks to see Aria, Spencer, Hanna, and Emily. While they're in her hospital room, she asks if it's true that Hanna pulled her out of the fire. When Hanna confirms this, Jenna asks her why she did it and she seems grateful to Hanna. Hanna doesn't answer her question, but simply responds "You're welcome."
Later in the episode, "A" is seen planting Garret's police badge at the scene of the fire, in order to implicate him in the attack on Jenna. Since Jenna is still in the hospital when this happens, she can be ruled out as the one behind the "A" scheme.
Later, Toby comes into her room questioning her as to why Garrett is watching their house. She says she doesn't know, and asks him to close the curtains. She pulls a slip of paper from a box on her night table, and gives it to him. Telling him that it was given to her by Garrett and was told to keep it safe. She lies, playing stupid, and claiming to not know what it is. Toby opens it revealing it to be the missing Page 5 of Alison DiLaurentis' autopsy report. They then go to the police station to give it to the police.
At the end, she is seen smacking a fly on her mirror and removes it's corpse, she turns back to her mirror with a sneaky smirk and continues to remove her makeup, revealing that she is indeed able to see. The surgery was successful after all, and for unknown reasons Jenna is lying to everyone and leading them to believe she is still 100% blind.
She is later seen at the masquerade party spying on Aria, and seen talking to Lucas and the Black Swan.
After Spencer tells Hanna to go back to Mona, Jenna walks past. They begin to discuss if Lucas, Jenna and The Black Swan are involved. and when Jenna bumps into someone, Aria comments on how Jenna seems blinder than she was last year. Later in the episode Jenna asks Aria to be her accompanist for a musical performance. She seems to be very careful in approaching Aria; quickly stating that she recognized her ringtone so she won't figure out that she can see.
When Emily is taking her English quiz, she sees a girl put her hair up the same way the driver had her hair "That Night". The next thing Emily remembered was seeing Jenna looking over smiling at someone next to her.Toby figures out that Jenna has been refilling her prescription for eye drops, even though her surgery didn't work. The girls decide set a trap to find out if Jenna can see; Spencer leaves the earring above the sink to see what Jenna's reaction would be. With two girls hiding and spying per stall, Jenna walks in and walks toward the sink. When she spots the earring she takes her glasses off and inspects it. The girls see that Jenna is not blind; as Jenna leaves the bathroom the girls argue over Jenna's sight. As soon as the door closes, Aria exclaims "Bitch can see!". But Spencer says, "We can use this information against her."
At the end of the episode all the Liars confront her. Jenna tells the girls she's been able to see from the first operation and didn't tell anyone. It was the "only protection I had." Jenna said she thought Emily was so messed up that night that she wouldn't remember seeing her. Her plan was to take her home but Emily freaked out and jumped out of the car around 12:00 or 12:30. Jenna wants them to keep her secret because "I'm still a target." She thinks they owe her.
Jenna comes out about her being able to see for unknown reasons. She appears at school without the shades or the cane, and everyone except the Liars start congratulating her. When Spencer asks her why she says she feels a lot safer when she's in charge of what happens to her. She throws a party for her birthday at the coffee house.
CeCe calls Jenna and warns her not to date Nate. CeCe tells her she'll scratch her eyes out if she sees her with him and that CeCe's his girlfriend, and then Emily exclaims that Jenna used to be blind.
Her and Noel appear at his brother, Eric's, party. While Aria and Spencer are they play a game of "Truth". Her and Spencer face off and it leads up to Jenna asking Spencer where the video's are. Spencer she can have all the videos she wants when she reveals where Ali's body is.
She is seen by Nate and Emily at the Brew talking to Noel. when Noel goes to practice, Nate approaches her and tells her he has a gift for her but never had the chance to give it to her because she ditched him. Jenna ignores this and attempts to leave but Nate won't let her go by. Nate decides to leave but in the background you can see Jenna sit back down
Hanna informs that Ted has the video, and now her moms deciding what to do with it. She tells her she and her friends didn't give it to them, and Jenna just says we'll see what happens. When Nate discovers she had been faking being blind for a while, he calls her out and tells her not to act like she doesn't see him. Later, she shows up at Emily's a little scared saying she needs to tell her something but seeing that she has company she just warns her to be very careful with who she spends time with and is seen getting into a cab and is possibly leaving town since the driver was putting luggage in the trunk.
Jenna is dressed up as a pirate. When Noel starts to choke, she shouts "do something". When Noel showed that it was a prank, she started laughing.
Jenna is mentioned by Spencer that she transferred schools.
Jenna meets with Shana in the park and they appear to be very friendly. She tells Shana that "they" will all be there Friday and she knows what she needs to do. Shana asks about her doctor's appointment and Jenna implies she may be losing her sight again, with Shana telling her that even in her darkest days, she'll be there for her.
While out for a run, Emily sees Melissa enter Jenna's house. Inside, Melissa and Jenna seem to be arguing with Jenna telling Melissa that "they have the tapes" and Melissa tells her that "those bitches will be at the lodge at 9." Melissa gives Shana a copy of the invitation.
The night of the "party" Toby sees a girl in the woods just before he gets knocked out from behind. Many fans believe the girl he sees is Jenna but it has not been confirmed.
We see the four liars and Mona driving back to Rosewood. They come upon Wilden's police car that Hanna and Aria previously pushed into a lake. The video recorder is playing the incident where Hanna's mom ran over Wilden, but this time they see that afterward, Jenna and Shana rushed over to his body and dragged him away.
In a later scene Jenna approaches Emily outside her house. Because of the way the scene is shot, we can see that Jenna is losing her vision again. We also see she has a burn on her hand; implying she was at the lodge the night of the fire. She tells Emily that she and Wilden were friends and that she has a message for Toby in case anything happens to her.
Everyone who saw Ali that night is waking up dead meaning Wilden saw Ali, which she said Garrett told her. Since Toby isn't taking Jenna's calls and she knows he and Emily are still friends, she asks Emily to tell him that she never meant to hurt him.Later, at Wilden's funeral we see that Jenna is wearing her glasses again and being escorted by Nigel Wright, indicating her vision continues to decline.
Spencer and Aria eavesdrop on a conversation Shana and Jenna are having. It's revealed Jenna believes Alison is still alive. Later, Jenna is seen with Shana at Emily's surprise birthday party. Spencer asks Jenna if she's losing her sight because she is wearing her sunglasses, but Jenna replies " I see everything I need to". Aria begs Jenna to tell her what she knows, but Jenna seems afraid. Later, Emily finds a body face down in the lake, and it is Jenna. Someone had hit her on the back of the head and she fell into the lake. She is unconscious, but is alive and is taken to a hospital. Spencer asks Shana who Jenna is so afraid of, and Shana replies "Cece Drake."
In one of Ali's she visits Jenna and shows her the video of her and Toby, Alison who at this point is trying to find out who A is threatens Jenna to not come back to town. Once she has left however Ali receives a text from A, it reads "Bitch can't see you, but I can -A".
Sitting on her bedroom floor crying, Jenna hears movement around her room and calls out, “whose there? Is someone there?” but she gets no answer.
At Aria’s front door, Jenna tells her “I knew it was you in my bedroom today”, and she wants to know what Aria was doing in her house. Aria asks her if she wants to come inside, she can make them some tea, but all Jenna would like is an answer. Aria tells her she heard about Shana and wanted to see if she was okay, and Jenna wonders why Aria would care if she is okay. Aria tells her with Alison back, it is bringing back a lot of stuff for everyone and they all feel really terrible about their part in the accident. Jenna reminds Aria that she still has all her friends, while she on the other hand, doesn’t have anyone left. As Jenna is turning to leave, Aria again offers her tea, and tells her that while she didn’t really know Shana, Jenna can tell her all about Shana. Turning back around, Jenna tells Aria that she thinks that would help, “thank you, Aria”.
Pulling up to a picnic ground, Sydney and Jenna step out of Sydney's car. Sydney comments on the mustang parked in front of them, and Jenna tells her that it used to be hers. Walking over to Mona, Sydney informs her that the Liars do not want things to go back to the way they were. Jenna says that they remember the way Alison treated them, like they were her dolls. Mona is happy by this and thinks that maybe they can get rid of Alison. The three girls turn to look as a third car pulls up.
Jenna walks into the Optometrists office with the guidance of Sydney.
Walking out of a consulting room and into the waiting room, Jenna and Sydney stop when Emily recognises Sydney. When Emily asks Sydney what she is doing at the Optometrists, Jenna explains that Sydney was her ride, before asking if that is a problem. Emily wonders when Jenna and Sydney became friends, and when Jenna tries to get Sydney to walk away with her, Spencer tells Sydney that Emily asked her a question. Stepping in, Jenna says that it sounded more like an accusation, and when Emily asks Sydney why she never mentioned she and Jenna were friends, Jenna comments that “maybe it never came up”. Spencer tells Jenna that maybe she should let Sydney speak for herself, and when Jenna asks, “excuse me?”, Spencer comments that when you ask the organ grinder a question you don’t really want to hear from the monkey. Jenna asks Sydney if they can “please leave”, and when Emily tries to get them to wait, Jenna wonders, “for more insults?”, before questioning Spencer and Emily how long it is going to take to realise that they are nervous around the wrong person, “I’m not Alison”. Linking her arm with Sydney’s, Jenna starts to move off, “come on Syd”.
Jenna is mingling with residents of Shady Days Nursing Home.
Unbeknownst at the time, Jenna is one of Alison’s followers as Alison makes her grand entrance at the Masquerade Ice Ball.
Still wearing a masquerade mask, Jenna and another of Alison’s followers, later revealed as Sydney, pose for a photo with Lucas, who is dressed as Santa Claus. Lucas tells the two masked beauties to come in closer, and after the photo is taken, he wishes them a Merry Christmas.
After gaining Emily’s attention, Jenna and Sydney begin walking through the crowd, with Sydney looking over her shoulder to make sure Emily follows. As Emily enters the room which has been draped off with fabric, Jenna sits on the couch, while Sydney reveals herself to Emily and explains that she led Emily here because she doesn’t want Alison to see them talking. As Sydney walks towards Jenna, Emily tells Sydney that she really gets around, and questions if Jenna knows Sydney is with Alison now. Jenna then takes off her mask and reveals herself to Emily, “when I first moved to Rosewood, Alison offered to be my friend. I made the mistake of saying no. When she asked me this time, I gave her the right answer”. Sydney tells Emily that she promises that they’re not the enemy, but Emily says that they are sleeping with the enemy. Jenna tells Emily that until someone puts “Ali away”, they’re just doing what they have to do to survive, “I’m sure you and your friends understand that”. Emily then tells Jenna and Sydney that they think Alison killed Mona, and Sydney comments that she and Jenna do to.
Season 4 (3/24)
Season 5 (3/25)
Season 7 (7/20)
Jenna is obsessed with Toby, whom she forced into a sexual relationship with her in the past. After Toby returned from juvie, Jenna seemed to still have feelings for him, since she got jealous everytime Emily, Spencer or any other girl was talking to him.
In Season 1 and before the show started, Jenna was romantically involved with Garrett by having a secret relationship. While they were dating, she thought that he killed Alison with a lacrosse stick and together, stole the fifth page of Alison's autopsy. They ended the relationship when Garrett went to jail.
Jenna seems interested in Nate St. Germain, Maya's alleged cousin. She is seen flirting with him in "That Girl is Poison". When Jenna first sees him, they stare at each other. She talks to him about his drawings and invites him to her birthday party, where they talk and flirt. In "Crazy", Nate buys her a candle as a late birthday present and sets a date with her. He asks Emily to help him pick out something better than the candle he had bought.
It's revealed later that Jenna got involved with Nate, only because she saw him killing Maya.
After Noel and Mona broke up in Season 2, Jenna becomes close to Noel and it gets clearly that she is dating him. They may have been together all summer, although it is unclear. The girls are unsure as to why they broke up. They had been secretly spying on their relationship, making sure that Jenna didn't tell Mona that she kissed Noel twice during the period of Noel and Mona's relationship. They had been close, as if the two were keeping a secret, not just from Mona, but from the girls too. It is unclear when the relationship ended.
In "A DAngerous GAme", Jenna is talking on the phone with someone who is going to protect her. Later, the viewers find out that the mysterious person from "UnmAsked" is the person Jenna meets again now at the park, Shana. They hold hands as Jenna gives her instructions on what "she needs to do". Shana seems to be taking care of Jenna and watches over her. In "'A' is for A-l-i-v-e", Mona reveals that Jenna and Shana knew each other before she came to town and Shana might be in love with Jenna. Shana later tracks Alison and the girls up to New York where she tries to kill Alison, all out of revenge for what Ali did to Jenna. She told them that she indeed did have feelings for Jenna.
She is seen talking to Ian in "The Badass Seed", but is not friends with him. Ian doesn't seem to like or trust Jenna, but they do have ties. She is also seen in Alison's house with Garret and Ian through a film that Ian is making in Alison's room which later shows Melissa come through the door yelling 'Where is she?!', implying that she is friends with all of the N.A.T. Club.
She is seen talking to Mona in the first Halloween special. After Jenna's very sexual display of her lady Gaga costume, and Ali coming up to Jenna and trying to be friends, which Jenna refuses, Mona comes up to tell her that her costume is better than Ali's. Jenna smilingly tells her that she better not tell Ali, to which Mona says "she doesn't scare me". Both of them smile.
However, what ever friendship that was implied shattered later on when Mona begins to hate Jenna because she stole Noel Kahn from her. Regardless of Mona's hatred, Jenna still joined Mona's Army in Season 5, because both of them were afraid of Alison's return.
She is seen talking to Melissa at the Masquerade Ball in "UnmAsked". Both of them, along with Shana, form The Alliance, but their intentions are unknown. Mona told The Liars that both Jenna and Shana are afraid of Melissa.
Sydney and Jenna have known each other before "Pilot". Sydney first met Jenna when she was a volunteer for the school of the visually impaired in Philadelphia. She was there the day Alison threatened Jenna with the N.A.T. videos. Sydney reveals to Emily in "March of Crimes" that she fixed Jenna up after the visit seeing that she was an emotional wreck. Jenna reached out to Sydney upon hearing that Alison was alive and coming back to Rosewood. Sydney is first seen with Jenna in "Miss Me x 100" when they both arrive at the park to meet with Mona. They appear to share an uncanny resemblance and are working with Mona to take down Alison. Spencer and Emily confront Jenna and Sydney at the eye doctor's office. Emily realizes that she can't trust Sydney because she's allies with Jenna. In "How the 'A' Stole Christmas", Emily refers to Sydney as Jenna's eyes and ears. Jenna attends the Dilaurentis Ice Ball with Sydney by her side. Jenna and Sydney explain later on to Emily how they are only with Alison because they are too scared to wrong her as Jenna has already made the mistake of saying no to Alison's friendship.
Sara and Jenna first meet in "Along Comes Mary". They both checked into The Radley Hotel and ordered a drink. Sara talked to her about how they have a common enemy relationship with The Liars. They easily clicked and started to become friends. The Liars pointed out that they are their biggest threats, and that they possibly could team up to tear up their alibi.
- Jenna had sexually molested her step-brother Toby. Jenna is very sexually aggressive, as shown by her behavior at the Halloween party, and seems comfortable using sex as a way to control men.
- She is blinded by a supposed prank gone wrong set up by Alison with the help of the other Liars. Towards the end of Season 2. she got eye surgery that restored her vision on at least one eye. However, she still lets everybody believe that she still cannot see, with the exception of a mystery-person she meets up with in a park in the second season's finale (later revealed to be Shana).
- She paid Caleb to spy on Hanna in order to keep the secret of her having forced herself on her step brother Toby. Jenna was slapped by Hanna after Hanna finds out that Caleb was being paid by Jenna to get close to her and to spy on her.
- She put a note in Jason's pocket saying "I know what you did". The note was intended to make him think he killed his sister Ali, which she knows he did not. She did this to cover up for Garrett, her love interest at the time, because she thought he had killed Alison.
- Before her blindness, Jenna was shown as having the capability of giving Ali competition for the Queen Bee title, Ali gets intimidated and suggests that they team up instead, but Jenna refuses, saying that she prefers to pick her own friends.
- Jenna is shown to be able to play the flute well.
- Jenna uses a flashdrive in "Someone to Watch Over Me". It is unclear how she can operate it without seeing, but it is mentioned that she has a special computer for the blind. In the same episode, Jenna uses Caleb's locker combination, 2-1-4, to leave something in his locker. How she opened his locker without seeing is a mystery, as the number markings are not indented very well. Another combination with numbers far from zero might have given her even more trouble.
- Jenna thinks that Garrett Reynolds killed Ali with a field hockey stick, but he only whacked the tree with it twice. Since she's blind, she was fooled by Garrett to believe he had done it.
- Jenna was thought to be bisexual, but due to her personality (ie. using others to get what she wants: "means to an end"), it was theorised she was just using Shana's crush on her to her advantage.
- By "A is for A-L-I-V-E", her vision has gotten much worse, as seen by needing someone to hold onto (like in "Pilot") and the return of her black sunglasses.
- She might have been the one that Toby saw or she's the one that hit him over the head in "A DAngerous GAme".
- Jenna is featured as a major recurring character in the first three seasons and in the seventh season. She was downgraded to a guest character for the fourth and fifth season.
- Season 6 was the only season she was absent from and was only mentioned in "Last Dance", when she went to the prom with Lucas Gottesman.
- Jenna gets a new pair of sunglasses in Season 7.
Spencer: So when did you move back to Rosewood? Last we heard, you were at a school in Philadelphia for the... visually impaired.
Jenna: It's okay, Spencer. You can say blind. It's not a dirty word.
Jenna [to the Liars]: We've all made mistakes. Remember, I'm still paying for yours.
Jenna [to Ezra Fitz]: I'm fascinated by the nature of evil.
Jenna: I don't need a special flashlight to know what people around here are hiding. This school is filled with phonies and liars. They're everywhere.
Jenna [to the Liars]: I've never been the one you really need to fear.
Jenna [speaking at Alison's memorial]: We think we know who we are, but we don't. Not until something bad happens to us, and then all the useless things fall away, and we're left with who we really are. I learned that from Alison DiLaurentis. My whole life, I thought I knew who she was, but I found out the truth when she came and talked to me at the hospital. I found out that she was the strongest person that I had ever met. And it's her strength that touched so many people, shaped them. That's her real legacy. That's how her memory will endure, in the actions of those she inspired in so many different ways. From all of us... thank you, Alison.
Jenna [to the Liars]: Whisper, whisper, whisper, it is almost as if Alison is still here.
Jenna [to Hanna]: I never had a problem with my ears, Hanna. I guess we'll just have to see how it all turns out.
Jenna [to Emily]: It seems to me that everyone who saw Ali the night she went missing, is waking up dead.
