Scully and Mulder in “Millennium”

Scully

How well do you know this man?

Mulder

Only by reputation - He, uh, left VICAP before I got there. But he's been called the greatest criminal profiler Quantico ever produced.

Scully

So what's he doing here?

Mulder

Well, apparently he checked himself in for a 30-day rehabilitation - I take it the last few years haven't been too kind to him. But if there's anybody that can tell us about the Millennium Group, it's him. He used to consult for them. Later, he fought to bring them down at the expense of his own career and reputation.

Scully

Single-minded.

Mulder

Yeah.

Scully

Sounds like someone I know.
