Hall of Infinite Doors
When you return the girl is not with the counseller, she is in a group of the other counsellers from the club. The counseller asks for the note and you hand it over confidently. He takes a glance at it, mumbles something about it not having any signiture, but smiles and tells you he'll see what he can do for you. He moves to the group of counsellers. Immediately a female slightly older than the others pulls out a cell phone. The others call the other children in, maybe for a group game. It seems to take a long time for the counsellers to agree to let you take the girl. You are just about to decide wether to approach the group or scrap the project for the day when you hear sirens. Shit, they called the police! You have been busted!
