"Two years," Bobby says, and the question makes him wonder about the Commander. It's not really an appropriate question - not to ask your CO, not really - but it slips out of his mouth anyway. "How long have you served aboard the Enterprise?" He catches himself. "Sir?"

He's a good engineer, but after four years at the Academy and two years as an officer, he still struggles sometimes with military protocol. All that yes, sir, no, sir, three bags full, sir stuff. To be honest, most of the time he'd rather just keep his head down and get on with the work.

But he wanted to see the universe - and if you want to do that, really do that, Starfleet's the only place to be.

Well, he's definitely seeing the universe now.
