Scully: It seems to me that the best relationships, the ones that last, are frequently the ones that are rooted in friendship. You know, one day you look at the person and you see something more than you did the night before. Like a switch has been flicked somewhere. And the person who was just a friend is suddenly the only person you can ever imagine yourself with.
Mulder: Scully, I was like you once. I didn't know who to trust. Then I... I chose another path... another life, another fate, where I found my sister. The end of my world was unrecognizable and upside down. There was one thing that remained the same. You were my friend, and you told me the truth. Even when the world was falling apart, you were my constant. My touchstone.
Scully: And you are mine.
Mulder: You know, they say when you talk to God it's prayer, but when God talks to you, it's schizophrenia.
Deep Throat: Trust no one.
Mulder: Sorry, nobody down here but the FBI's most unwanted.
Scully: Agent Mulder? I'm Dana Scully. I've been assigned to work with you.
Mulder: Oh, isn't it nice to be suddenly so highly regarded. So, who did you tick off to get stuck with this detail, Scully?
Scully: Actually, I'm looking forward to working with you. I've heard a lot about you.
Mulder: Oh, really? I was under the impression that you were sent to spy on me.
Scully: Sure, fine, whatever.
Deep Throat: And a lie, Mr. Mulder, is most convincingly hidden between two truths.
Mulder: Scully, you are the only one I trust.
Mulder: Sometimes the only sane answer to an insane world is insanity.
Mulder: [upon seeing the Cigarette Smoking Man in a hospital] Please tell me you're here with severe chest pains.
Scully: I have never met anyone so passionate and dedicated to a belief as you. It's so intense that sometimes it's blinding.
Mulder: I've often felt that dreams are answers to questions we haven't yet figured out how to ask.
Mulder: If coincidences are coincidences, why do they feel so contrived?
Susanne Modeski: No matter how paranoid you are, you're not paranoid enough.
Scully: What if there was only one choice and all the other ones were wrong? And there were signs along the way to pay attention to.
Mulder: Mmm. And all the choices would then lead to this very moment. One wrong turn, and we wouldn't be sitting here together. Well, that says a lot. That says a lot, a lot, a lot.
Mulder: The truth will save you, Scully. I think it'll save both of us.
Scully: Last time you were so engrossed, it turned out you were reading the "Adult Video News."
Skinner: [repeated closing phrase] That will be all.

Samantha Mulder: Do we have to watch this, Fox?
Mulder: Leave it. I'm watching "The Magician" at nine.
Samantha Mulder: Mom and Dad said I could watch some movie, Buttmunch.
Mulder: They're next door at the Gallren's and they said I'm in charge.
Mulder: Hey. Get out of my life.
Mulder: I'm watching The Magician.
Mulder: Now look. The fuse is blown.
Samantha Mulder: Fox!
Mulder: Samantha! Samantha!
Doctor: You're gonna have to tell me who you are first!

Mulder: Oh no.

Tad O'Malley: If I'm going to put my ass out there, I need to know if it's hanging by a thread.
Skinner: Mulder/Scully? Let me have a word with you.
Cigarette Smoking Man: There's nothing more dangerous than someone with nothing left to lose.

Mulder: What can I do about a Lie with an Official Seal on it?
Scully: Stop or I'll shoot!
Scully: Mulder, even if...
