"What?" he repeats again, brows furrowed further and lips twisted in a look that's stuck halfway between being confused and a little freaked out. But he shakes his head a bit to rid himself of those feelings so he can assess what the hell is happening. It's the attempt at a handshake — the quick withdraw upon some realization that makes things sort of click for him. They brushed shoulders, the guy froze up, stumbled, and now spoke of things that he probably shouldn't know. Somehow, he saw it.

"Uh, shit. Thanks?" He laughs awkwardly, nodding his head a bit in greeting since yes, a handshake is a terrible idea. "Ryder. Just got here a few days ago so you'll excuse me if I'm having a little trouble understanding how literally anything around here works."

He makes a...vague gesture, indicating things like this right here because honestly.
