Unfortunately it took another half an hour or so before there was a sound by the door. Barty knocked, then called out. "Sam?! Sam, if you are in there and you don't want me coming in, I don't give a fuck."

He was not about to respect Sam's rules regarding their interactions right now, instead he was already kneeling down to pick the lock. He had only heard rumours, nothing substantial. Maybe Sam was simply in there, entirely fine and very angry with him for invading. He would prefer that to any of what he feared.
