Luther Devarro: [prevents Mac from asking for medical help over the radio] Don't make... I started it. I end it. That includes me.

Luther Devarro: I never intended to save the world but somebody had to be held accountable. Those that made the same promise I did. Promise to protect the neighbourhood, not to eat it alive. To defend it, not to become the worst threat it had ever known.
Mac Taylor: Now you've caused even more bloodshed. Killing people won't solve it. We're fighting the same fight. Why didn't you come to me? We could have taken them down together.
Luther Devarro: Because old habits die hard, and we're different kind of people. I gain closure here, Detective, in the spirit of what I created. I have no other choice. It all ends here. Tonight.

Luther Devarro: Next generation. Teach them a little respect.
Mac Taylor: You've been away for a while. Things have changed.
Luther Devarro: Question is: for better or worse? In our time, it wasn't about guns. It was the knuckle game, remember? I had snap in my shoulder. I hit you, you were hurting.
Mac Taylor: What I remember is you beating a rival gang member to a pulp. That's what put you away.
Luther Devarro: Defending the neighborhood. This place has always welcomed me with open arms.
Mac Taylor: So did El Pu�o. What you started only got stronger when you went away.
Luther Devarro: Yeah, no thanks to you. Every couple of months, I'd find one of my men in the mess hall.
Mac Taylor: Didn't want you to get lonely.

Luther Devarro: Sitting in my cell, hearing about how El Pu�o was the most feared and violent gang. Inmates coming up to me and paying respect. I wanted to tear it down!
Mac Taylor: Did you honestly think you could do that by killing the heads of the gang? They'll all be replaced by others.

Luther Devarro: The rules of the street. This wasn't about taking over... [coughs so he won't choke on his blood] This was about making things right.

Luther Vandeross: I can certainly answer any of your questions or write them down and have Evie respond by e-mail.
Det. Don Flack: That's not how this works. See, we're old school. We're all old light bulbs and cold concrete rooms.

Mac Taylor [to Lisa Brigosa]: Last I saw you, you were in Catholic school.
Lisa Brigosa: Back when I robbed nuns for fun.

Mac Taylor [to Luther Devarro]: I want to know if I'm gonna have a problem with your crew.
Luther Devarro: This your way of paying condolences? Last time I checked, it was one of my men who had holes burned into him.
Mac Taylor: And killing more people is going to make it right?
Luther Devarro: What's the alternative, turn it over to the NYPD? Cops like to see us as defendants or, better yet, deceased.
Mac Taylor: Doesn't have to be that way.
Luther Devarro: I didn't make the rules.

Mac Taylor [to Luther Devarro]: You want to teach the next generation? You tell them revenge lands them in prison or a grave. You're a man of intelligence. Reason with them.
Luther Devarro: Men can reason all they want. Machines got minds of their own.
Mac Taylor: I want your assurance that this is not the beginning of a war.
Luther Devarro: I hear your concern but I can't make that assurance.

Mac Taylor [about James Belson]: He must have checked himself out of the hospital right after Danny came to see him. Met up with the Kendricks brothers, killed them, then tracked Heath down.
Jo Danville: That's a lot of activity for someone who just had abdominal surgery. He's going to need medical attention soon.
Mac Taylor: Well, he's got five million reasons to play through the pain.

Mac Taylor [to Chief Carver]: The sooner the people know, the faster they can take steps to protect themselves.
Chief Ted Carver: It's not your call, all right? And I'm not about to create a citywide panic.
Mac Taylor: Well, I don't think we can control that in this day and age, and why even have me up there at all?
Chief Ted Carver: You're the head of the crime lab. It's gonna look like I'm withholding something if you're conveniently absent.

Mac Taylor [to Chief Carver]: You prepared to tell the public the truth now?
Chief Ted Carver: How sure are we it's the same guy?
Mac Taylor: Sure as I was before.
Chief Ted Carver: So, I hear you've got a primary suspect. Somebody you're familiar with?
Mac Taylor: Michael Reynolds, missing person 15 years ago. I handled the case.
Chief Ted Carver: Complete whack job?
Mac Taylor: Well, he was held against his will for three years, physically and emotionally abused the whole time. It affected him, if that's what you mean.
Chief Ted Carver: Your stunt at the press conference didn't stop him from killing this guy, did it?

Mac Taylor [to Jo]: Looking for something?
Jo Danville: Oh, only the best hamburger in all five boroughs. Harvey's double-decker with the works.

Mac Taylor [to Roland Carson]: You, uh... you recognize anyone?
Roland Carson: Should I?
Mac Taylor: They're the men who broke into your apartment last night. They're also former clients of yours. You care to explain that?
Roland Carson: I've defended a lot of criminals, Detective. It's my job.
Mac Taylor: That's not an answer.
Roland Carson: I don't know what else to tell you. Maybe you should ask one of them.
Mac Taylor: They're a little bit dead right now. Killed with a handgun registered to you.

Mac Taylor [to Tom Reynolds]: Your family turned away from you. We all did. I know what that must have been like.
Tom Reynolds: You don't know anything. No one knows what that's like living in a hole! Abandoned. Ignored. No one knows what that's like!
Mac Taylor: Killing people won't change that!
Tom Reynolds: Look around you. What's going on. All of this is because of me! Because of what I'm doing!
Mac Taylor: There are other ways, Tom!
Tom Reynolds: I've tried all the other ways. Nothing changes. It's just the same! But now? Now it's different. People will know me. They'll know my name. They'll know my face.
