Alison's story was about Alice and her twin sister as they happily play on Halloween with their dolls. They get into an argument about one of the dolls, and Alice's twin sister takes a butcher knife out of the drawer and stabs it into Alice's heart. As her parents entered the kitchen, they see one Alice on the floor with blood oozing out of her body. The other girl sees her parents and grins broadly at the sight. She is then sent to a mental institution which is believed to have been Radley Sanitarium.
- Alison's story is similar to her feud with her own twin, Courtney, in the books.
- The story is referenced by Hanna in "Grave New World" when she sees two little blonde girls in red coats.
- One of the twins makes an appearance in "This Is A Dark Ride" at The Marin's house. However, only Ashley sees and speaks to her.
- The story foreshadows the "evil twin" plot lines that take place later in the series.
