Chara doesn't move from their spot against the wall. Maybe they can't.

Frisk doesn't know how to finish and meanwhile, Chara doesn't know where to begin.

Why were you in my bed is one question except a memory helpfully filters in: "You don't have to sleep on the floor! I don't mind sharing." Another question- Did you know which one I was?

Their thoughts go around and around like this for what feels like forever.

Finally, they manage to ask: "...Why?"
