At the first meeting for the Psi Alpha Chi sorority, Rebecca Taylor asks the girls to engage in a "get to know people speed dating" activity. When Claire begins her speed date with Allison, Allison immediately says that Claire used to be a cheerleader, and Claire asks Allison how she knows that. Allison reveals that Gretchen had told her.
Later that night, at the mixer party, when Rebecca tries to drop a flagpole on Claire, Claire jumps out of the way. Allison asks if Claire is alright. Later, Allison joins the other sorority sister and pledges in Claire's dorm room to initiate Claire and Gretchen.
Allison, along with Becky and a masked sorority sister, bust in Claire and Gretchen's dorm room and try to kidnap them. When Claire fights back, Allison watches as Becky explains the situation. Then, after dropping Claire, Gretchen, Olivia and Ashley at the slaughterhouse, Allison and the others leave.
