You are having a sleepover with your four friends, Nathan, Micheal, Charlotte, and... A girl... a random girl.

I mean, you hadn't noticed it before, but there was a random girl here, too. All of you were just hanging out with her in Charlotte's room, yet none of you knew who she was.

Sat on Charlotte's top bunk you watch as all your friends act casual around her, and you try to think of a way to get rid of her since all of you were too scared to confront her.
