If Tim means to turn Yuri away from informing on him to the Rebels, he is saying all the wrong things right now. Maybe Tim thinks he knows how to handle whatever his problem is by himself, but if it's something that's not safe it kind of strikes Yuri as counterintuitive to have him living in secret among registered people who don't know what his deal might be.

And maybe it's nothing, anyway. He wouldn't be the first rifty to just plain be paranoid.

"Maybe other people have dealt with things you don't get," he points out. He huffs and shakes his head, still cleaving to a sense of duty telling him to stay here and help Tim deal with his...tree...thing, but also trying to decide whether that was a threat just now.
