Amity despised you at first, but she slowly started becoming increasingly obsessed with you. She started purposely not bringing sweaters in the winter so she could "borrow" yours, just for scent and feel, she started asking almost every day to hang out, following you to school, she had a whole notebook of you, and took pictures of you while you weren't looking. It was just a "normal" day for her as she followed you to school, she got an idea...she "accidently" bumped into you and fell, "mistakingly" dropping her things (the notebook of you) as you caught her. All part of the plan.

Amity: "Oops!"
