"I mean idiots getting lost because they have no sense of direction--that never changes. If you're the first from your planet, that must make you a special kind of idiot, too." It's...not...exactly personal that she calls him an idiot?! She's at least equally insulting to most strangers. (And then wonders why they get so grumpy around her...)

And, well, it's a good thing he clarifies that he's into movies rather than dressup, even as the way he keeps talking just makes her raise a skeptical eyebrow. "I don't need to know about your hobbies." It's sort of an attempt to poke fun at him over dressing up, and her light tone gives it away, before she gets more serious again. "But you might actually have an advantage there, assuming he's seen the same movies as you."
