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. Character in print Pretty Little Liars is a series of books which revolves around the lives of four teenagers in Rosewood, Pennsylvania whom each struggle with different physical and psychological issues, as well as living in danger because of a dangerous stalker who emerges after the four's best friend and leader Alison DiLaurentis vanishes and is found dead. 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 with paranoid schizophrenia. The family then moved to Rosewood to avoid attention and shortened their surname from Day-DiLaurentis to just DiLaurentis.
