JACK: Arkan leisure crawler, first generation. Collectors' item. Don't see many of those around these days. Tosh, send a polite message saying great to see them, but could they please get the hell out of our atmosphere, they're spooking the locals.

TOSH: Done.

GWEN: Shouldn't we be apprehending it? Investigating it?

JACK: Oh, please. You interrogate an Arkan, you'll be in there for a month. And that's just the first question. They are so boring. Besides, they're mostly made of liquid. The cells would be a mess.
