It's probably good Dipper can't peek in there, all things considered. There's always a lot happening in a sort of unfortunate jumble, and it really is just a toss-up of how equipped he is to sort it out on any given day. That he only comes across as nervous means he's doing pretty good!

"I suppose it beats sitting here not knowing where to start. You wouldn't happen to know a place a man could barter for some pants?"

He figures if they're really on top of things they can do that as part of the tour, on the way to... wherever he winds up. That's still a big question mark.
