"Soon enough," said a voice in her head as she envisioned Spencer, Aria, Emily and Hanna. "Soon enough, I'm coming to get you all."


Alison Lauren DiLaurentis was the most popular girl at her middle school Rosewood Day. Before the DiLaurentis family moved to Rosewood their last name was Day-DiLaurentis, but changed it due to their secret daughter, Courtney. Many people thought Courtney was insane, but it was Alison that was insane and jealous for her more popular twin Courtney. Alison is the prettier twin but people loved Courtney because she was nicer so, Alison made her switch with her. Courtney got mad and got into fight, was caught and sent away. One day Courtney came to visit and switched places with her and Alison was sent away. Alison later killed her sister because of it. Alison wanted to get revenge on her friends and tried to kill them many times with the help of Nick and will not stop until the liars are dead.


Alison has long, wavy; honey-blonde hair, and deep cerulean blue eyes. Her eyes are a little bluer and wider than Courtney's, her hair is slightly darker, her waist slightly thinner, and her breasts are slightly larger. She has a heart-shaped face, bow shaped lips, and a lithe figure. Alison claims that she is 'the more beautiful twin' and even Courtney says Ali always looks a little better than she does.

Because of her revenge and due to the burn marks because of the fire in the book Wanted Ali's current appearance, as of Deadly, is: Emily trembled as she felt Ali’s steely, murderous gaze upon her. Here she was, finally. Real. Alive. Sickly and way too thin, her jeans hanging off her hips, her arms like toothpicks, cords and veins standing out in her neck. There was dirt all over her face, her hair was matted, and one of her front teeth had rotted, spoiling her smile. It was like scribbling over the Mona Lisa. A beautiful girl, the most beautiful girl, envied by everyone, adored by Emily herself. Now she was just a tarnished ruin. A twisted freak.


Alison was the typical rich, popular, mean girl in Rosewood. That is until Courtney took her life and she was sent to the mental hospital. In Ali's Pretty Little Lies we found out that Ali has always been crazy and she framed Courtney for being mentally ill. Alison is described as extremely bitchy, manipulative, and deranged. She's a stalking murderer as well.

  • Distinctive feature: Her heart-shaped face.
  • Known for: Her insanity, her cruelty and vengeful nature and beauty
  • Favorite things: Her popularity, old life, and revenge.
  • Biggest regret: Letting Courtney take her life, and bragging about her time capsule piece.
  • Worst offense: Killing Courtney, Ian, Jenna, and Kyla; being A, and attempting to kill the Liars numerous times.


Alison was always popular but she was mean, unlike her sister who was popular but kind. Alison DiLaurentis made her parents think that her nicer twin was crazy but that was untrue. Alison forced her twin sister Country impersonate her periodically in order for her to ultimately appear to be the manipulative one. Eventually Courtney was sent away. Alison herself never got to have the full middle school experience, as Courtney managed to fool their parents into taking Alison to the mental institute instead of her during her first visit home. Furious, she killed Courtney two years later and attempted to get revenge on her sister's friends as well. She was the second A.

As kids, Alison and Courtney were friends. As Alison ultimately became jealous of her more popular sister she forced Courtney to impersonate her, while tormenting Courtney at the same time to the point that Courtney snapped and got into a physical fight with her. When the doctors were called by girls' parents, Courtney panicked and revealed that Alison was threatening her and forcing to impersonate her. Alison (who predicted her sisters action, and making herself seem very innocent) claimed it was not true and decided that her sister had to go (allegedly for everyone's safety). In the outcome, Alison's master plan worked: Courtney was recognized as a paranoid schizophrenic. Her family moved then to Rosewood to avoid attention and shortened their surname Day-DiLaurentis to DiLaurentis.

When she first arrives in Rosewood Day in third grade, Alison holds commanding reign over the school, with every girl wanting to be her and every guy wanting to date her. During a Thursday afternoon in sixth grade, Alison spots a flyer for the Time Capsule Tradition, and boasts that she will have a flag piece given to her by her brother Jason DiLaurentis. That weekend, Courtney was home from the Radley, her old mental institute that was being turned into a hotel. Courtney was hoping to stay at home but Alison lied to her parents that Courtney threatened her, and they decided to put Courtney in a new mental clinic, the Preserve at Addison-Stevens. Sometime that Friday, Alison's ring with her signature "A" was stolen by her twin. On Saturday morning - the day Courtney was to be taken to the Preserve - Hanna Marin, Aria Montgomery, Spencer Hastings and Emily Fields arrive at the DiLaurentis home to steal Alison's flag piece. Courtney spots them immediately and goes to inform her sister about that. But Alison ignores the fact, reveals her lie to Courtney, and again teases her (malicious yelling in the DiLaurentis house which the Liars heard was actually Alison's one, not Courtney's), which causes another argument between sisters after which Alison lefts Courtney alone. Using this time, Courtney decides to complete her plan of escape to normal life and comes out, pretending to be her sister before the Liars.

Courtney successfully tricks her mother into taking Alison to the Preserve. Alison is shocked and insists that she's not Courtney; however, without her ring and with Courtney outside chatting it up with four nobodies from school, she's fighting a losing war. Furious, Alison realizes the only way out is to pretend that she is Courtney. While in the Preserve, her first roommate is Tabitha Clark, and her second roommate is Iris.

Two years later, her parents bring her home for the summer, believing that she is improving and are considering a slow transition to letting her stay home for good. Meanwhile, Courtney has befriended the girls who Alison thinks are the 'un-cool' people of Rosewood Day - Hanna, Aria, Spencer and Emily, and had taken over Alison's life completely. While they are having a sleepover with "Ali" in Spencer's barn Alison spies on them, taking pictures with a Polaroid camera. She later buried several of the photos in the vast woods bordering her family's Victorian mansion and Spencer's estate.

When Courtney runs into the woods after an argument with Spencer, Alison appeared and began threatening and taunting Courtney. Then the two girls began wrestling on the ground. Courtney said that all she wanted was for the two of them to be sisters and Alison says that she wants to kill Courtney, but she can't. At that moment someone else came, then Alison pushed her into the hole for the gazebo. In the few minutes before Courtney died she recognized both voices, her sister's and another one. They have planned the murder all along. Alison and her accomplice throw a lot of dirt on Courtney's body.

Alison goes back to the house and tries to switch back to Alison. But the next day, her parents find out she is not wearing her initial ring and the Jenna Thing bracelet, and assume she is Courtney. Then the Liars come and tell Mrs. DiLaurentis they don't know where "Ali" is. The construction crew pours concrete into the hole, unaware that Courtney's body is lying in it. Mrs. DiLaurentis thinks that "Courtney" did something horrible to her twin sister, and tells Alison to pack and then drove her to the Preserve. Alison sees Spencer on her driveway, and vows revenge with the help of the mysterious person. The media stakes out the DiLaurentis mansion and jumps on the story of a beautiful rich girl who is "missing."

About four years later, Alison takes over from Mona Vanderwaal becomes the second "A" so she can continue to stalk the Pretty Little Liars and have her vengeance. Unfortunately, Ian Thomas, who is the prime suspect in Courtney's death, has been conducting his own little investigation and has discovered her family's biggest secret: her twin sister and her insanity. He also seems to be figuring out who exactly he saw arguing with "Ali" in the woods on the night of her murder, and so she kills Ian to keep her secrets safe. Alison later attempts to kill the girls by setting the woods near Spencer's estate on fire. However, Alison is trapped by a fallen branch and is nearly killed as well. Aria finds her and rescues her, and the rest of the Pretty Little Liars see her, but Alison runs away before anyone else can see her, leaving the public to think the girls are hallucinating or possibly even lying for attention. Alison later kills her neighbor Jenna Cavanaugh in the book "Heartless" because Jenna is one of the few people who know the secret that the DiLaurentis family have a third child. She worries that Jenna also suspected the possibility of the first switch instigated by her dead sister. She pins Jenna's death as well as her sister's on a pervy construction worker who used to work on the DiLaurentis gazebo project years ago.

Alison returns in "Wanted," when her parents, who still think she is Courtney, introduce her to the rest of Rosewood, saying that she was "Alison's" twin, and they didn't want her caught up in the media attention following "Alison's" death. Alison convinces the rest of the Pretty Little Liars that she is actually the best friend they knew, claiming that her twin Courtney must have snuck out the house and was killed by the construction worker, causing a mix up with their identities. They all eventually believe her and are thrilled to have their best friend back; of course they have to keep pretending they only know her as Courtney. However, Aria maintains a bit of wariness around Alison, and Spencer inadvertently notes that her sister Melissa Hastings had warned her to stay away from "Courtney". Dismayed by this information, Ali keeps a close eye on Melissa and soon realizes she has figured out the truth. She kidnaps and drugs a bound and gagged Melissa in a closet with Ian's corpse before she could get to the police.

Alison invites them to a holiday home in the Poconos they had always used to visit with Courtney after the school's Valentines dance. Alison cajoles them into re-enacting the hypnotizing session during the sleepover and they reluctantly agree. Alison planned the night so she could set fire to the house, killing the Liars and Melissa and finishing what she started with Courtney. Only again, she fails and the Liars and Melissa escape the house. The house eventually explodes from the fire and it goes up in flames, leaving the girls to believe Alison is still inside and certainly dead. Emily is painfully aware that she left the door of the structure open, leaving the possibility for Alison to escape.

It's revealed in "Deadly," that she was badly injured from the Poconos fire and that she and her accomplice fled when they heard the sirens. Later in the book it's also revealed that Nick Maxwell from Ali's Pretty Little Lies was her accomplice and secret boyfriend. After he's arrested for their crimes together we find out Ali was the one to report him. Most likely to protect and save herself. In the very last chapter we learn that Ali has taken all of Nicks money and plans to get her hair properly cut, her teeth fixed and plastic surgery for her burns. She states that she will get even with the liars if it is the last thing she does. Her new alias is now Maxine Preptwill.

In "Vicious" Emily manages to catch Ali (who had been staying with her mother) and get her arrested, this meant that the Liars were free from jail and all harassment from "A".

Memorable Quotes

To: Four Bitches. From: A.

Once upon a time, there were two beautiful girls named Ali and Courtney - but one of them was crazy. And as you know, with a few magical twists of fate, Ali became Courtney for a while. But what you don't know is that Courtney became Ali, too.

You heard me right, Pretty Little Losers...and it's all because of you. Remember when you stalked me in my backyard for the Time Capsule Flag? And remember that girl who trotted out to the lawn and talked to you? That wasn't me. As you so astutely figured out, Courtney was home switching from the Radley to the Preserve that weekend. And oh, how poor widdle Courtney didn't want to go. She had her neat, crazy little life at Radley...and she didn't want to start over in a hospital.

If she had to start over somewhere, it was going to be Rosewood. And start over she did. She was supposed to go to the Preserve the very morning she saw you skulking around my yard - and man, did she jump on the chance fast. One minute she and I were arguing - I was so happy she was on her way out - and the next she was out in the yard, pretending to be me, talking to you guys like you were BFF's. Talking about my flag as if she hadn't been the one who'd stolen it first and ruined my masterpiece with that stupid wishing well. And how was I supposed to know that everyone - my mom, my dad, even my brother - would think it was me out there and Courtney inside? How was I supposed to know my mom would grab me and say it's time to go, Courtney? I pleaded with her that I was Ali, but my mom didn't believe me, all because Courtney took my A-is-for-Ali ring when I wasn't looking. My mom yelled outside to the girl who wasn't Ali that we were leaving, and the girl who wasn't Ali turned, smiled, and said, Bye!

Off we went. Courtney got my perfect life, and I got her wrecked one. Just like that.

She ruined everything. She put her lips all over Ian Thomas. She nearly got arrested for blinding prissy Jenna Cavanaugh. She ditched Naomi and Riley, the coolest girls at school. But the very worst thing she did in my name was choose four new best friends in their place. Girls she knew I would never look twice at, girls who weren't special in any way. Girls who she knew would fall all over her, desperate for the opportunity to be in her exclusive club. The girls who'd help her get everything she wanted.

Any of this sound familiar, ladies?

But don't worry. This little fairy tale can still have a happy ending for me. I saw to it that my sister paid for what she did. And now, so will you.

I tried to burn you. I tried to make you crazy. I tried to have you arrested. I've even messed with you this week - surprise! I flung myself at Aria's boyfriend. I sent Hanna fake tickets to a certain fashion show. I let Em believe there was a happily-ever-after for us after all. Smooch! And Spencer...I have a surprise for you. Look closely! It's right under your nose.

I suppose I should thank Courtney for her meticulous diary keeping. It helped me - and Mona - so much. It's all led up to this big moment. The curtain's about to go up, bitches, and the show is about to begin. Get ready to meet your maker. It won't be long now.
