you see your "friend". the girl...or boy...or whatever... wearing a smiling theatre mask. she wears a grey t-shirt, fingerless gloves, and baggy black cargo pants. she is being bullied by one of the other classmates

classmate: Hey maskface! watch this!

the classmate throws a stone at the masked. the mask cracks. half of it falls off. the formerly masked girl is now being identified as the "serial killer" Telilah Marleys. she turns around and sees you

Telilah: Oh dear!
