Gladys Jennip: And what does that have to do with you?
Nathan Muir: Nothing.
Charles Harker: So, sir, you and Muir came up together, right?
'Troy Fogler: Mmm-hmm.
Charles Harker: How well do you know him?
Troy Fogler: No one knows Nathan, not really.
Charles Harker: Do you trust him?
Troy Fogler: He's a man who got the job done.
Tom Bishop: So, when do I get my first assignment?
Nathan Muir: When I decide you're ready.
Nathan Muir: You just gave her four pieces of personal information for one dubious impersonal fact. 1) You're straight, 2)You're engaged, 3)Tomorrow's your girls birthday, and 4)You have terrible taste in women's clothing.
''Tom Bishop: Just trying to find out where she got that dress.
Nathan Muir: What if she were an asset? You told her four lies that now have to be true.
Tom Bishop: I thought spies drank martinis.
Nathan Muir: Scotch, never less than twelve years old.
Tom Bishop: Is that right? Agency rules?
Nathan Muir: My rules.
Robert Aiken: Patricia?
Nathan Muir: Yeah, my third wife.
Dr. William Byars: My God, how many wives have you had?
Nathan Muir: Four. You want to hear about them or Bishop?
Tom Bishop: Don't tell me that. Don't fucking tell me that. You didn't look in his eyes. Don't tell me that!
Nathan Muir: He was your asset, somebody you use for information.
Tom Bishop: Ah, Jesus Christ, you just... You don't just trade these people like they're baseball cards! It's not a fucking game!
Nathan Muir: Oh, yes it is. It's exactly what it is. And it's no kid's game either. This is a whole other game. And it's serious and it's dangerous. And it's not one you want to lose.
Tom Bishop: Nathan, we killed this man. We used him and we killed him. Okay then, you got to help me understand this one. You got... Nathan, what are we doing here? And don't give me some bullshit about the greater good.
Nathan Muir: That's exactly what it's about. Because what we do is unfortunately very, very necessary. And if you're not willing to sacrifice scum like Schmidt for those that want nothing more than their freedom, then you better take a long hard look at your chosen profession, my friend. Because it doesn't get any easier. You wanna walk? You wanna walk, walk.
Tom Bishop: Fuck your rules, Nathan.
Nathan Muir: Okay, but tonight they saved your life.
Nathan Muir: When I was a kid I used to spend summers on my uncle's farm. And he had this plow horse he used to work with everyday. He really loved that plow horse. One summer she came up lame. It could barely stand. The vet offered to put her down. You know what my uncle said?
Charles Harker: No, Muir, what did he say?
Nathan Muir: He said, "Why would I ask somebody else to kill a horse that belonged to me?"
Nathan Muir: We didn't know when the Doc was going to be giving the Shiek his physical, but it was our one and only opportunity to take him out. So I didn't have the usual time to butter him up. Which means we needed twice the sex with half the foreplay.
Tom Bishop: Happy Birthday, Nathan. Did you know Langley has seven different birth dates for you?
Nathan Muir: And they're all wrong.
Tom Bishop: I know, believe me, it wasn't easy. KGB, Mossad, also wrong. Fortunately I was well trained.
Anna Cathcart: The Scotch is older than she is...
Nathan Muir: Am I supposed to feel bad about that?
Troy Fogler: [re-enters the room looking faintly amused] There's been... an incident, in China.
Charles Harker: [looks confused for a moment, then shocked as he realises that Muir has played them all] Oh, Jesus Christ!
