SCULLY: Mulder, when I met you five years ago, you told me that your sister had been abducted... by aliens. That that event had marked you so deeply, that nothing else mattered. I didn't believe you, but I followed you, on nothing more than your faith that the truth was out there, based not on facts, not on science, but on your memories that your sister had been taken from you. Your memories were all that you had.

MULDER: I don't trust those memories now.

SCULLY: Well, whether you trust them or not, they've led you here. And me. But I have no memories to either trust nor distrust, and if you ask me now to follow you again, to stand behind you in what you now believe, without knowing what happened to me out there, without those memories, I can't. I won't.

MULDER: Cassandra Spender was taken aboard a military aircraft, as part of the staging.

SKINNER: Over the past five years I've doubted you, only to be persuaded by the power of your belief in extraterrestrial phenomena, and I'm doubting you now, not because of that belief, but because extraterrestrial phenomena is frankly the more plausible explanation.

KRYCEK: You must be losing it, Mulder. I could beat you with one hand.

MULDER: Isn't that how you like to beat yourself? If those are my last words I can do better.

KRYCEK: Hear this, Agent Mulder... listen very carefully because what I'm telling you is deadly serious. There is a war raging, and unless you pull your head out of the sand, you and I and about five billion other people are going to go the way of the dinosaur. I'm talking planned invasion. The colonization of this planet by an extraterrestrial race.

MULDER: I thought you were serious.

KRYCEK: Kazakhstan, Skyland Mountain, the site in Pennsylvania. They're all alien lighthouses where the colonization will begin, but where now, a battle's being waged. A struggle for heaven and earth. Where there is one law: fight or die. And one rule: resist or serve.

MULDER: Serve who?

KRYCEK: No, not who. What.
