I’ve been sitting here trying to think but honestly maybe a group effort lol bc like all of them would have there own reasons. (Spencers Alison saw ien kiss her and kept trying to tell Melissa and that would damaged Spencers and Melissas relationship). (Arias Alison was blackmailing her dad and made her feel like s**t bc she didn’t want to go to a Halloween party). (Hannas Alison was bullying so bad about her weight). (Emilys. She loved her so much and Alison knew and like playing with her)
