Okay, the other man was definitely flirting. John was...flattered. His years in space had taught him to be pretty open to all sorts, though he wasn't sure how to really respond to how Bill was looking at him. The other man was attractive and yeah, but John was kind of odd about being observed after some previous adventures...and very, very awkward encounters with a few aliens along the way.
He offered Bill an almost shy smile, blinking and shrugging. "Yeah, fresh is the word, I guess." Clearing his throat and sipping his coffee, he just nodded. "This place is...weird. Sorry. I'm still wrapping my head around all of this. I haven't seen another human in years- er, Sebaceans look human. Have accents kinda like yours. That's why I ask."
Or at least they sounded that way to him. It was hard to explain. "Universal translator. I don't know why- anyway, where are you from?"
