Out in the hallway Alistair begins knocking on and opening doors at random, checking for empty rooms. He knew there had to be some around but he didn't actually know which ones were empty and which ones weren't. In his defense he'd just moved into the first empty room he'd found when he first went looking - having a private room of his own was a fairly novel experience for him too so he hadn't been picky about it.]
