Aiden: [Stella is examining a diamond] I've been processing dirt all day and you've been shopping at Tiffany's.

Aiden: [to Detective Thacker] Do me a favor. Don't check out my ass when a kid's dead in the street. Show some respect.

Aiden: [walking into a strip club] Holy boob-job, Batman.

Aiden: Did you find anything else?
Flack: I haven't gone in yet.
Aiden: What?? Flack, you little scaredy cat, you don't believe these stories about this place being haunted?
Flack: I was doing my job, Aiden: getting statements from witnesses.
Aiden: Stel, you smell that?
Stella: Yeah. Chicken. Well, I did hear the one about the monk who went crazy and killed the others is true.
Flack: The 1-2-2 gets calls about strange noises coming from this place all the time.
Aiden: Will you stop? That's just an old urban legend.
Stella: Aiden, I think you'd better hold Flack's hand.
Flack: Yeah, okay...cute.

Aiden: How does a potential shortstop become a crime-scene investigator?
Danny: That's real easy. Get into a fight, break your wrist, and then graduate from the police academy, top of my class.
Aiden: Dangerous, Danny Messer.
Danny: Very dangerous.

Aiden: I used to climb over the velvet ropes at this place. Now I'm ducking under crime scene tape.

Ali Rand: I'm not doing this anymore... I'm dropping the charges.
Flack: Let's be clear about something. There is no dropping these charges, okay? You can't unring this bell.
Ali Rand: You cannot force me to testify.
Flack: No. But the D.A. can, and he will. You're in this, Ali.

Ali Rand: What are you, a cop or something?
Frank Waters: Yeah, I used to be, sort of. I worked on the John Curtis case in DC.
Ali Rand: You did a hell of a job.
Frank Waters: Yeah, well, so did you. I was in court today. If you're gonna dose yourself with GHB, you better figure out the right levels.

Ali Rand: You said I was gonna be safe. But that maniac is back out there. Who do you think he's pissed at right now, the crime lab?
Flack: Look, Ali, you just need to take a breath here.
Ali Rand: They're calling me a liar in the newspaper, a whore.
Flack: I told you not to read the papers.

Allison Scott [to Jo]: Don't you dare talk to me about grief, because my fiancé died in my arms.
Jo Danville: You're absolutely right, Allison, that was a terrible tragedy. I can only imagine the anger you felt. God himself couldn't save someone who wanted to hurt my family. I would hunt them down. I would make them suffer like they had never suffered before. I would need them to feel the unrelenting pain that I felt. But what if I was wrong? What if I hurt the wrong person? I could never live with myself.

Amber Stanton: (during her interrogation) Whenever I see a useless piece of human trash walk away without consequence, I feel violated again... Bentley was smiling... Kaplan was going about his life as if nothing had happened...
Mac: So you became a predator? A killer?
Amber Stanton: I think of myself as an arbiter of justice.

Angel: (about their suspect) Security claims they got her on camera, stealing men's clothing.
Danny: She's keeping busy. Maybe she's stealling for her boyfriend too.
Stella: Well, she's stealing a number of items in a variety of sizes.
Angel: Than she's not just stealing for two.
Danny: Probably fencing the stuff.
Angell: This is not pawn shop goods she's taking down. These are exclusive items.
Stella: For an exclusive clientele... she's a personal shop-lifter.

Angell: (strapping on a kevlar vest, sees Flack staring at her) ...What?
Flack: (gruffly) You look good in a vest.
Angell: (laughs)

Angell: Hey. I thought you were off today.
Flack: Yeah, something came up with Danny. It - (looks up, seeing other Detectives nearby) It's a long story. How 'bout I tell you later over an Irish coffee?
Angell: I think I know just the place...

Angell: Monsieur, qu'avez vous vu dans le train ?
Flack: The sexiest thing I ever heard.
