The Doctor addresses the lady behind the desk. "Hello there. We're trying to find some... historical records, I suppose. Anything you have that might have to do with what happened to the environment outside."

She looks up at him pleasantly enough. "All such records are restricted, sir. I'll need your authorization code," she says in a tone that strongly suggests she doesn't believe he has one.

"Of course you will. Padme, love, give this nice young lady our authorization code."
