Ah, a medical officer -- Wash might've been able to guess, from the look of him. Soldiers tend to be able to hold themselves a certain way, to act and talk a certain way, and most of the time it's easy to recognize it in someone else.

"Good to know we have a medical officer on board," he says, and of course there's clearly a medical team on the base, they're in the damn med bay, but well. It's clear he doesn't trust them. A slight pause, and. "Did they do anything to you?"

Just echoing Ratchet's previous question. It's not all that unusual of a question to ask, especially for a medical officer, but he's curious.
