"It's nice to meet you," says Kariya, silently scanning for parasites, which might tell him when someone's around. It's sort of embarrassing to be able to tell who has parasites. Because how are you supposed to bring that up diplomatically? But that's not the issue now! He keeps an eye out, though he's not sure what he'll be able to do if someone attacks them. He'll try to help, somehow.

"I hope we'll be able to talk again after all this is over." Because of course, it will be over, and everything will be fine!
