Mulder: Brown Mountain, Scully, that doesn't ring a bell?
Mulder: Brown Mountain lights? It's a famous atmospheric phenomenon dating back nearly 700 years, witnessed by thousands of people, back to the Cherokee Indians. Strange multicolored lights are seen to dance above the peak of the mountain. There's been no geological explanation, no scientific credible explanation at all.
Scully: And, what does that have to do with these two?
Mulder: Well, as I said, there is no credible scientific explanation, but there are those of us that believe that these strange multicolored lights are really...
Scully: UFOs. Extra-terrestrial visitors from beyond who apparently have nothing better to do than buzz one mountain over and over again for 700 years.
Mulder: It sounds like crap when you say it.
Scully: Mulder, can you just, for once, just for the novelty of it, come up with the simplest explanation? The most logical one, instead of automatically jumping to UFOs or Bigfoot or...
Mulder: Scully, in 6 years how often have I been wrong? No, seriously. I mean, every time I bring a new case we go through this perfunctory dance, you tell me I'm not being scientifically rigorous and that I'm off my nut; and in the end who turns out to be right like 98.9 percent of the time? I just think I've earned the benefit of the doubt here.
Scully: My role in the X-files have always been to provide a rational, scientific perspective to cases that would seem to defy explanation, a counterpoint to Agent Mulder.
Walter Skinner: And you have done that. You have performed admirably.
Scully: Have I? How many X-files have my scientific approach fully and satisfactorily explained?
Walter Skinner: Your reports have consistently made sense of his conclusions.
Mulder: Scully, I want you to put aside your scientific bias for a moment. 'Cause what I'm about to tell you is going to change your life forever. Your life, my life, the life of everybody on this planet.
Scully: I still can't believe it.
Richard 'Ringo' Langly: I half expect Mulder to knock on the door and say "Surprise!"
Scully: Mulder, this is not reality. This is a hallucination. It has to be. And either I am having it, or you are having it or we are having it together.
Mulder: Scully, how could we simply will ourselves out of a chemical hallucination?
Scully: Well, the fact remains we did.
Mulder: Did we? Can you name me one drug that loses its effect once the user realizes it's in his system?
Walter Skinner: I assume the effects wore off to the point that you were both able to make your escape.
Mulder: Scully, how long were we underground? Hours? Half a day? How come our bodies don't show any effects of being burned by the digestive fluids? We were covered in hydrochloric acid. Yet look at our skin. Nothing.
Walter Skinner: Agent Mulder, where are you going with this?
Mulder: Scully... we never escaped. We're still trapped underground!
