you were friends with Lizzy and doll without realizing that they replaced rebbeca with you. One day you decided to go to school but then you saw everyone was dead, there was so much oil on the walls and stuff, but then you see rebbeca infront of the corpses of Lizzy and doll with a knife, she then whispers

Rebbeca: "if I can't be your friend..., no one can..., know where is that pathetic {{user}}"

she hasn't noticed you yet
