Flack: You and your brother are about as smart as bait. Makes your ransom drop plan a little inconsistent.
Jake Williams: Why do you say that?
Flack: Because it wasn't a stupid plan. You almost had us. So where'd you get the idea? Did you see it on TV or in a movie?

Flack: You play poker?
Stella: Occasionally. You have a problem with that?
Flack: Yeah. You're physically incapable of keeping a straight face.
Stella: Really?
Flack: Now Mac. There's a man with a poker face. Who knows what he's thinking?

Flack: You recognize that guy?
Marty Bosch: Yeah, it's, uh... Ryan Richards. I've seen him fight. Why?
Flack: There were three murders in the city last night. Two of them have been solved.
Marty Bosch: And the third?
Flack: Ryan Richards.

Flack: You're going away for murder, Mark. The only question is how long. We're offering you a chance to do the right thing. Chance for a lighter sentence.

Jo: It's not just a mistake, Frank. You know I have to alert the defense.
Frank Waters: Oh, you do that, this whole case could blow up.
Jo: You've given me no choice.

Frank Waters: Why didn't you just ignore my mistake?
Jo: I had a responsibility, Frank. To Serena, to the other victims.
Frank Waters: If you'd just put your personal ethics to the side one time, none of this would be happening now.

George Foodim: After hitting a few bars, I went back to Brett's apartment and that's when I found him. I started to call the cops, right? But it's not like there was anything I could do. He was already dead. I had to get him to the park.
Flack: Uh, y-you're gonna have to help us out here, pal. Why did you have to get Brett to the park?
George Foodim: It was a bet. He was engaged twice before, couldn't go through with it. I bet our buddy Toby that Brett would definitely show up this time. There was no way I was gonna lose.
Mac: Whoa, whoa. You stuffed, dressed and moved your dead friend for a bet?
George Foodim: It was a hundred grand, man. I...I don't have it. And if I didn't pay up, Toby would have gone to my dad.
Det. Flack: It never occurred to you, with your friend being dead and all, that just maybe the bet was off?
George Foodim: I told you.
Flack: Yeah. Fifteen shots of tequila. I heard you.
George Foodim: Yeah, well it made... made sense yesterday morning. I feel bad. If you knew Brett, Brett, (laughs a bit) Yeah, I mean, he, he would've laughed. He would've done the same thing, I'm telling you.

George Williams: When we saw she was dead, we needed a way out of town.

Detective Mac Taylor: [normally] What... makes you think something's wrong?

Gina Mitchum: (to Mac) I speak with my hands. You speak with your eyes.

Grace Chandler: I know you think I had something to do with this.
Mac: Most of the people who sit in this chair... they lie. Each time that happens we get a little bit better at knowing who's telling the truth and who's not.
Grace Chandler: And how about me, Detective. Am I a liar?
Mac: I'll let you know.
