Gibbs: This all started the day you showed up.
Rebecca: Oh. Rule 39 - there's no such thing as coincidence.
Gibbs: That's right.
Rebecca: First of all, I gave you that rule.
Gibbs: No you didn't.
Rebecca: Yes, I did. And second of all, use your head, J. I'm clearly being set up here. Obviously someone knew that I was coming to see you. That's your lead. Not me.

Gibbs: Hey! You got something to say?
Bishop: Not in a million years.
Tony: Actually, I just want you to know I understand completely. I do. There's nothing more enticing than forbidden fruit. Especially the kind you can spoon with.

Vance: Tom Morrow may have a solve. We pull it off this could all go away.
Gibbs: For all of us?
Vance: Clean slate.
Gibbs: What's the catch?
Vance: It might kill you.
Gibbs: So could a bag of clams.
Vance: [laughs] We sure picked one hell of a career didn't we Gibbs?
Gibbs: Got to make a living Leon.

[after killing Salim] Let's go home.

Ziva: I'm sorry Tony. I know you wanted the car but I just didn't think it was a good idea to sell it to you.
Tony: Why not?
Ziva: Because I really liked my Mini.
Tony: Me too!
Ziva: And I didn't want anything to happen to it.
Tony: What are you saying?
McGee: She's saying you're a car killer.
Tony: What?
Ziva: A car killer.
Gibbs: Everybody needs a hobby.

Mugger: Hey I found that cellphone in the trash, man. Somebody must have thrown it away.
Gibbs: Really?
Mugger: Yup.
Gibbs: Okay. Thanks for coming. [Mugger gets up to leave] Sit down.

Gibbs: Bottom line?
Ducky: Lt. Arnett's death was accidental.

Ducky: If the cases are connected, does that infer that Arnett was also murdered?
Gibbs: And we've got our hands full.

Vance: What's his ultimate target?
Gibbs: I don't know.
Vance: I've got to notify Homeland, FBI and the ATF.

Tony: He's got another one.
McGee: Well, that's great, but without cell's numbers, we can't track it." Tony: THINK, McSidekick! Use the leading man! Harness those powers!
McGee: It was an unregistered phone. It was pricey for a cop.
Tony: Bingo!
Gibbs: Shelley got it from a bust.

Relax director. I'm just here to cross some "t"s and dot some "i"s. I'll be as quick and painless as possible.

Parsons

Gibbs: So do we? Lay off?
Vance: The man killed my wife, Gibbs.
