Other mistake: When Jenny and Matt first enter his apartment, the deadbolt on the door is intact. Later, when Professor Bedlam's minion kicks the door open the plate and deadlatch are missing. The act of kicking the door open might destroy the striker plate in the door jamb, or it might blow the entire lock body through the door, but it couldn't neatly remove the plate and bolt alone.
