Det. Lindsay Monroe: [seeing the Vinett's] What do they want?

Det. Lindsay Monroe: You ever see what a full grown black bear does to a man?

Det. Mac Taylor: Somebody doesn't like Harry Belafonte.

Det. Mac Taylor: There are three things that I'll protect at any cost: the honor of this country, the safety of this city, and the integrity of this lab. As scientists, we have a great deal of power, the ability to assign guilt or innocence. But when we analyze a crime scene, we collect pieces of evidence, we make a promise to the people of this city. A promise to handle that evidence with respect, integrity, and good faith. When you broke the seal, you broke that promise.
Detective Aiden Burn: I didn't do it. I didn't plant the evidence. I wanted to. Man, I wanted to, but I couldn't go through with it. I knew I couldn't live with that.
Det. Mac Taylor: Is it that you couldn't live with it, or you couldn't compromise the integrity of this office?
Detective Aiden Burn: You know how much this place means to me, Mac. But that son of a bitch raped Regina twice, and he's gonna get away with it twice?
Det. Mac Taylor: And if the credibility of our findings is suspect, how many more do you think will walk? Ten? Twenty? A hundred? Truth is, Aiden, I can't have someone like that working in this lab. You're fired.
Detective Aiden Burn: [handing over her badge] Truth is I can't do this anymore, Mac. I mean, I got to be honest with you. If somethin' like this ever happened again, I don't think I'd trust myself. And I'm sorry I let you down. Just do me a favor, huh? Catch this guy for Regina.
Det. Mac Taylor: I will. This folder... will be right here on my desk till we get him.

Det. Mac Taylor: This whole thing was an insurance scam.

Det. Mac Taylor: We need to do a full workup, including rape kit.

Det. Mac Taylor: [about a little girl's teddy bear] So did Franklin help out or did he lawyer up?

Det. Mac Taylor: [makes a face as Lindsay Monroe smears some "odor screen" on his upper lip] And now it's on my lip.

Det. Stella Bonasera: Let me give you a tip. Protein bars, comfortable shoes, and at least four hours of sleep a night.

Det. Stella Bonasera: No problem.

Det. Stella Bonasera: No, Mac wants them right. That's all that matters.

Det. Stella Bonasera: That woman burned beyond recognition in your car, was a DETECTIVE!

Det. Stella Bonasera: Well, welcome to the crime lab.

Det. Stella Bonasera: [about Horatio being served with a notice] Listen, I get named on these things all the time. Our union attorney's great of you want me to give you his number.
Lieutenant Horatio Caine: This is a matter outside the job.
Det. Stella Bonasera: Sorry.
Lieutenant Horatio Caine: I have a number of memories up here and not all are good. So I apologize.

Detective Danny Messer: So this guy walks over to a place he's never been and dies of no apparent cause?
Detective Don Flack: At this point, yeah.
