The look she gives him over his questioning is...well, it's unimpressed. Her uniform is grey, the grey of an acting [insert rank here], but it's still a Starfleet uniform with a communicator.

The uniform, she suspects, isn't the problem at all.

Still, she pointedly puts the smile back on and shakes his hand.

"You'll have a bit of a time-culture shock, I'm afraid. Starfleet's part of the United Federation of Planets now, not just Earth. And there's lots of different cultures and species involved in that. And that's not even counting everyone else who Q's winked here. But we're trying to get people back to where they originally from, if that's feasible. In the meantime, typical Starfleet hospitality, you'll be assigned a room after a medical check, and you're free to pitch in where you can if you wanted some duties, as long as the captain signs off on it."

There's a pause.

"You might need to study to catch up, though. But classes are starting soon to help with that."
