Look, Esteban has pointy ears, which automatically pegs him as not human. Beyond that, Wash isn't about to ask. Now is not the time.

He just tilts his head briefly at the question - it would've been a shrug, but his shoulders are occupied and he doesn't want to jostle Esteban. "A room." His, off his bed, but he figures he'll just run it through the dryer before tonight. It's not a big deal. "I'll put it back when we're done. What room is yours?" Because if Esteban wants to sleep, then he'd probably better do it in a bed.
