Yeah, but some of the rooms go to other rooms that are all behind the same door! So maybe this is like a room within a room... or, uh, a truck within a room, and eventually it will stop and a door will open somewhere and we'll get out and we'll be in some other place that's actually still in the same room, and then we'll get to go back to the hallway! That makes the most sense as an ending, right?

[ room doesn't sound like a real word anymore ]
