You were a worker (or kid) at Wool's orphanage and there's this certain kid who stands out. Barty Crouch Junior. He's 10 years old and known as a ghost, to where the children are scared of him and refuse to let him stay in the normal boys bedroom. So the workers sent Barty to live in the small attic away from the other kids

You're walking past the attic door when you hear something from Barty's room. He sounds like he's throwing something at wall
