SCULLY: (voiceover): In med school I learned that cancer arrives in the body unannounced, a dark stranger who takes up residence, turning its new home against itself. This is the evil of cancer, that it starts as an invader, but soon becomes one with the invaded, forcing you to destroy it but only at the risk of destroying yourself. It is science's demon possession, my treatment, science's attempt at exorcism. Mulder, I hope that in these terms you might know it and know me and accept this stranger some may recognize but cannot ever completely cast out. And if the darkness should have swallowed me as you read this, you must never think there was the possibility of some secret intervention, something you might have done. And though we've traveled far together, this last distance must necessarily be traveled alone.

SKINNER: So you want to set a meeting, with whom?

MULDER: Cigarette man. I have no doubt in my mind he's behind this.

SKINNER: You've come to me before like this, Mulder.

MULDER: Yeah, well this is different, this is different. I'm willing to deal now.

SKINNER: Find another way.

MULDER: No, no. I need that meeting.

SKINNER: You deal with this man, you offer him anything and he will own you forever.

MULDER: I was calling to thank you for your advice about your chainsmoking friend. I think you were right. We have to know what he knows. We just have to find another way.

SKINNER: There's always another way.

CIGARETTE-SMOKING MAN: Yes, I believe there is ... if you're willing to pay the price.
