Smart kid, most people wouldn't get the alien thing, or even believe it. Does he realize they're talking about a completely different concept of aliens? Not at all.

"Yeah, right. But I'm the only cat who's an alien, and only descended from aliens who made themselves into cats... probably a pretty long time before I was born. And Dixingren aren't cats. Or crows or flowers or snakes. They just always look like humans and have fancy powers."

He wrinkles his nose, insofar as a cat can, and asks, "Is that their power? Replacing bones with flowers? It sounds... not very useful. And kind of gross."
