Oh yes, he's already squinting at the workshop through his phone. Might wonder if those bows have anything to do with the ones in Hyth's apartment.

Sure, that'll work! Emet at the very least will probably be scrutinizing everything at the fair, so I can't really think of any prompts I'd be opposed to. He's definitely very curious about all the machinery involved in the rides and how they work. Also interested (and suspicious about) the food. He might be coerced into participating in a game (while saying it's childish, but if he ends up with a prize he knows exactly who to pawn it off on).
