- Tom Quinn: You're a free man. You're a free man. You don't have to do this.
- Prof. Fred Roberts: I want to. I've made my choice.
- Tom Quinn: No Fred, I'm am begging you, please don't.
- Harry Pearce: I'm decommissioning you, Tom.
- Tom Quinn: Oh, don't be ridiculous, Harry.
- Harry Pearce: You are no longer an officer of the Service.
- Tom Quinn: Danny, Zoe, come on!
- Zoe Reynolds: [sighs] Just leave it.
- Tom Quinn: Come on, back me up!
- Danny Hunter: How exactly can we do that?
- Tom Quinn: Because we understand each other, we always have!
- Danny Hunter: Not anymore.
- [last lines]
- Tom Quinn: Everybody safe? Fred's family? What about Lawrence Sayle? You get him?
- [laughs wryly]
- Tom Quinn: Oh, of course, you can't tell me. I'm a member of the public now.
- Harry Pearce: You are. I envy you.
- Tom Quinn: I doubt that.
- Harry Pearce: No, I mean, if this thing is really leaving you, then...
- Tom Quinn: The spy thing? The urge to be secret, to give a false name, lead a false life.
- Harry Pearce: You'll get the really, very generous special pension.
- Tom Quinn: Payoff, for rogue officers here.
- Harry Pearce: You won't be disciplined, Tom.
- Tom Quinn: Thanks for that.
- Harry Pearce: And of course, you realize, we'll never meet again.
- Tom Quinn: Yeah.
- Harry Pearce: Good luck in the real world.
- Harry Pearce: Will North. You really want to go out with this man?
- Zoe Reynolds: Yes.
- Harry Pearce: [pauses] Takes a good snap, but he's obviously troublesome. Then again, if he wasn't, you wouldn't like him, would you?
- [first lines]
- Harry Pearce: [observing an explosion across a street] Well, that should get somebody's attention.
- Prof. Fred Roberts: What, you're saying MI-5 manufactured my whole career?
- Harry Pearce: We opened doors for you and, to your credit, you barged right through them.
- Zoe Reynolds: I'm afraid I can't let you do that, sir.
- Will North: And why not, miss?
- Zoe Reynolds: Are you accredited?
- Will North: Agence Presse Francais.
- Zoe Reynolds: [looking at his business card] Why France?
- Will North: [in a mock accent] Because I am French!
- [in his real accent]
- Will North: Well, actually, I freelance there a lot. In fact, I'm going to Paris this weekend. You could come.
- Zoe Reynolds: Just give me the camera.
- Ruth Evershed: I saw this happen to someone at GCHQ.
- Zoe Reynolds: What happened?
- Ruth Evershed: Their conscience exploded.
