Mulder: Why?
Deep Throat: Mmm, you've seen things that weren't to be seen. Care and discretion, are now imperative.
Mulder: I saw something I...
Deep Throat: As I said, I can provide you with information, but only so long as it's in my best interest to do so.
Mulder: What is your interest?
Deep Throat: The truth.
Mulder: I did see something, but it's gone, they took it from me, they erased it. You have to tell me what it was.
Deep Throat: A military UFO? Mr. Mulder, why are those like yourself, who believe in the existence of extra terrestrial life on this earth, not dissuaded by all the evidence to the contrary?
Mulder: Because, all the evidence to the contrary, is not entirely dissuasive.
Deep Throat: Precisely.
Mulder: They're here, aren't they?
Deep Throat: Mr. Mulder, they've been here for a long long time.
