Alison DiLaurentis

Alison Lauren DiLaurentis is a fictional character in the Pretty Little Liars book series, its television adaptation, and the spin-off series Pretty Little Liars: The Perfectionists. The character was created by American author Sara Shepard.

In the beginning of both the books and the television series, Alison is a central character who is shown mostly in flashbacks. The narrative is set when Alison mysteriously disappears and leaves the suburb of Rosewood shocked. Due to her position as a queen bee of Rosewood's social scene, Alison's actions and relations were constantly under scrutiny from the town's citizens. Sasha Pieterse, who portrays Alison on screen, has described the character as an indecisive person, showing herself as a ruthless, manipulative girl. Due to the massive reformulation on the story's timing, pacing and overall narrative for the television adaptation, the on-screen Alison DiLaurentis holds various differences from her literary counterpart, such as the fact that the latter has an identical twin sister, while the former does not.

Story lines

The twin sisters Alison and Courtney Day-DiLaurentis were born on June 6, 1990, the fruits of a secret sexual relationship between Jessica DiLaurentis and Peter Hastings. They were identical, but completely opposite in personality. Both were popular in her hometown, but Alison was known for her wickedness, unlike Courtney, who was admired for having a kind behavior. Disgusted by that fact, Alison began to make their parents—Jessica and Kenneth, the adoptive father—think that Courtney was psychologically damaged. Alison forced Courtney to impersonate her, which led to a physical fight between the two. When their parents tried to find a solution to the situation, Alison threw all the blame on Courtney, saying she was making up fake stories. Eventually Courtney was diagnosed as a paranoid schizophrenic. The family then moved to Rosewood to avoid attention and shortened their surname from Day-DiLaurentis to just DiLaurentis.

However, Alison did not enjoy the full high school experience. During a visitation to the family, Courtney tricked her parents by dressing up like Alison and Alison was taken to the hospital instead. That way, Courtney took the popular life of Alison, whereas Alison was hospitalized; from then on, a sense of hatred grew within Alison. Two years after Courtney took the reins, Alison returned to the DiLaurentis house for a visit. During a night when Courtney (posing as Alison) and her new friends—Spencer Hastings, Hanna Marin, Aria Montgomery and Emily Fields—were asleep, Alison reached them and she and Courtney got into a fight in the woods surrounding the DiLaurentis residence. The fight resulted in Courtney's death. Alison and her helper and boyfriend, Nick Maxwell, buried Courtney's body later on.

When Alison was about to get her life back, Courtney's friends warned Mrs. DiLaurentis that "Alison" was missing. Jessica then assumed that Courtney (Alison, actually) did something against her sister's life and sent her back to psychological hospital. Meanwhile, masons filled the hole where Courtney's body was buried to build a gazebo. Shortly after, "Alison" was reported missing. Three years later, Courtney's friends began to be pursued by someone named "A" who knew their greatest secrets and threatened them constantly. Months later, Mona Vanderwaal, a classmate of the girls and Alison, was revealed to be "A". Soon, Alison took the stalking method and began to chase the girls, seeking revenge for them having everything she always wanted.

Alison made small appearances during the period hiding behind the "A" mask. The DiLaurentis revealed the secret about the twins after a man named Billy Ford was arrested for murdering Alison, saying that they kept the sisters hidden for so long to avoid turmoil in town. Alison, posing as Courtney, someone unknown to the four girls, invited them to spend a weekend at the family home in the Poconos. There, they got together and the girls started thinking about introducing "Courtney" to the group. However, they were trapped inside a room and Alison soon revealed the whole truth about the death of the real Courtney, and about her desire for revenge. Alison then set the building on fire, but the girls managed to escape. When trying to escape the fire, Alison herself got several burns on her body and managed to escape with the help of Nick.

Alison then used the following weeks to recover from the fire whilst observing her victims. Nick stayed with her during her healing process, but Alison eventually discarded and incriminated him for everything she had committed, such as the homicides of Ian Thomas and Jenna Cavanaugh. In order to finally get her revenge, Alison wrote an entire diary with untrue stories of the girls torturing her while they were keeping her hostage. The piece was then found by the Rosewood P.D. and the girls were incriminated by the alleged death of Alison DiLaurentis. However, Emily faked her own death, and, while Alison and everyone else thought she was dead, she managed to reach Alison's lair—which was receiving help from Mrs. DiLaurentis—with police officers. The girls were eventually released from all charges, and Alison was definitely hospitalized.

Character on screen


Actress Sasha Pieterse was cast as Alison DiLaurentis in December 2009. Alison was the queen bee of her school and the most popular girl before her disappearance. Although she cared for her friends, she enjoyed to use their strongest secrets against them so that they could, according to her, stay together. Charming, manipulative, and highly intelligent, Ali was skilled at finding ways to get back at everyone, and many people hated her. After the reveal of Alison's fate in the ending of season 4, Pieterse confirmed that DiLaurentis' personality had drastically changed; she has to "figure out who she is. She's been hiding for so long, and she's a victim now." "Alison's a totally different person, so to see the way they treat her is going to be very interesting and to see the way that she gets affected by it is also going to be very interesting," Pieterse said.

Season 1

Alison DiLaurentis is introduced as a very popular girl from the suburb of Rosewood, Pennsylvania, and the leader of a clique composed by her, Spencer Hastings, Aria Montgomery, Emily Fields and Hanna Marin. The first minutes of the pilot episode show the five friends reunited in the barn-turned-loft of the Hastings family during a night of summer vacation. In the midst of night, Hanna, Emily and Aria wake up to see Spencer arriving back to the barn after leaving to somewhere. Spencer naively announces that she has heard a scream of Alison, seemingly shaken due to something. Shortly after, Alison is pronounced as a missing person, it's been a while since Alison went missing, and a year later her body is found buried in the backyard of the DiLaurentis' house. During the year that Alison is missing the friends grew apart, but after the introduction of "A" and the return of Aria Montgomery from a year in Iceland with her family, the friends reunite. "A" makes an appearance by sending threatening text messages to the girls and leading them into trouble. During the entire first season, Alison appears in flashbacks. In these flashbacks, Alison is shown as a ruthless, despicable, two-sided teenager who uses the others' secret against themselves.

Season 2

After Ian Thomas is pushed down by "A" from the top of a bell tower and his body goes missing, the girls are forced to keep their friendship a secret and to maintain therapy sessions with Dr. Anne Sullivan to discuss about Alison's absence in their lives, a fact that their parents believe to be the reason why the girls are behaving strangely. Days after, through Spencer's sister Melissa Hastings, the girls find Thomas' dead body, accompanied by a suicide letter in which he admits that he killed Alison. Following, the girls continue to be threatened by "A". Garrett Reynolds is arrested for Alison's murder after Jenna Marshall hands the Rosewood Police Department a missing page of Alison's autopsy.

The third season is set five months after the previous one. One night, Spencer, Hanna, Emily and Aria get together in Spencer's living room to drink and enjoy a life without a stalker. Emily, however, is still mourning over the death of her ex-girlfriend Maya St. Germain, who died in the same night of Mona's reveal. After drinking more than expected, the girls wake up in the midst of night to discover that Emily has disappeared. They later find her in the cemetery, standing over Alison's grave, with Alison's body missing.. With Emily drugged and they involved in a crime, the girls then promise to keep the secret. They dispose of all evidence connecting them to the happening, including all of Emily's clothes. A new person using the "A" identity soon restarts the stalking game. The new stalker threatens them with what happened previously. Mostly of the season's episodes revolve around the question of where Alison's remains are. The girls later on befriend new resident CeCe Drake, a woman physically and psychologically similar to Alison. Drake reveals to them that she and Alison were best friends when Alison was alive, years prior. Throughout the following episodes Drake gets intimate with the girls, who are suspicious of her Alison-like behavior. Later on, Alison is shown in more flashbacks of the night she disappeared, with some revealing that Alison met with CeCe, Aria's father, Jenna Marshall and Garrett Reynolds that night. In sequence, the girls discover, in Alison's biology notebook, a conversation between her and a friend in which Alison talks about a "beach hottie." The girls investigate while a figure using a red coat starts to appear periodically to them, and they begin to believe that it is Alison. In the meantime, Mona and Spencer's boyfriend Toby Cavanaugh are revealed as helpers (and double agents) of the new "A". With the help of the two, the girls plot a trap to catch "A," but the stalker uses their own setting against them, and, during a fire, the girls are saved by Red Coat. Hanna wakes up and sees Red Coat staring at her, and the person is revealed to be Alison. Afterwards, Mona and Spencer claim that they also saw Alison. On the way back to Rosewood, Mona reveals that Red Coat would sometimes wear a mask that looked like Alison's face, meaning that Red Coat could have just looked like Alison.

The girls later meet Carla Grunwald, who tells them that she helped Alison step out of the grave that she was buried; Grunwald then drove her to a hospital, but Alison ran away. With this confirmation, the girls start a quest to find Alison, following the steps of two persons using the Red Coat costume, one of them being revealed to be CeCe.
