OK, you've got the first room on the left, and the guy sawing wood in his sleep is the second on the left; you'd have to be deaf not to know that. Ah, but you've finally remembered that he went down the hall a ways, before he slipped into his room, and thus he must have went into the second room on the right. You listen for a moment at the door, but with the noise of the other guy, it'd be hard to hear a Mac truck coming, and as a (former) earth girl, you actually know what a truck sounds like! As quietly as possible, you open the door, and peek in. It's hard to tell, but there might be someone in the bottom bunk. It's impossible to tell about the upper bunk. Or, it might just be that Thomas left his room messy.
Ack! There shouldn't be anyone in there! Think I'll quietly close this door, and then go try the other one - if I don't wake whoever is in there up.
Nonsense! Obviously, the shadows are playing tricks on me, and Thomas left the bed a mess. I think I'll slid right on in here.
