Hmm. [He doesn't know what to think about that. On one hand, he wants to be all snarky and OH SO YOU WANT YOUR POKEMON TRAPPED HERE WITH YOU HUH?? HUH???....but on the other, a desire to be with one's team could indicate a trainer that cared......so meh. All he'll say is "hmm" for now. There will probably be time for snarkiness later.]

You have a Pikachu, I see. Who else have you brought with you?

[Just to clarify his interest (sort...of....by kind of lying a little but not really just sort of): ] In my youth, I was also a Pokemon trainer.
