"I'm Valentine," Valentine began, as though that in itself should suffice, but he was going to humor the class by adding the rest anyhow. "I come from nowhere in particular, really. I'm something of a traveler. I don't know if I love science here yet-- where I come from everything is different. Most things don't much care to obey whatever this 'law of gravity' thing is that people here keep talking about. Oh, and this is my real face, before anyone else asks."
He quirked his head thoughtfully, then gave a satisfied nod.

That should do.
