Leo wasn't being too serious at the bibiru, though he figured the one he named after the ice-cold man would not care if he started eating another person's hair. However he did notice Trahearne's mood shift, reflexively holding the bibiru closer to him.

"Huh? What? No! I wouldn't think that. I mean, you're human shaped and a lot nicer and uh....Look, okay the plants that tried to eat me were all of Mr. Klaus' Beyondian plants and they couldn't actually talk, they just tried to take a chunk out of me because they're honestly kinda scary like that. I don't know why he takes care of them. You're different then that and I'm pretty sure I'd be dead if you want to eat me."

He liked to talk when he got nervous. Please don't hate him, Trahearne.
