Mac: Today I got a call from the widow of Ben Melvoy.
Stella: The attorney from Jersey.
Mac: They had a toddler and a newborn. They were two weeks away from celebrating their tenth anniversary. Then he gets in the wrong cab.
Stella: My God.
Mac: But you know what hit me the hardest? She couldn't have been sweeter; held it together; didn't even cry. All she asked me to do was stop this killer from hurting somebody else. In spite of all the heartache and bloodshed he's causing, all I could really offer her was an apology. Are we gonna get this guy?
Stella: We have to. We have to.
(Danny calls Lindsay on the phone as she strolls down the street)

Mac: Triple murder in front of this bakery a year ago.
Danny: Markov... he's like the Sammy the Bull of Russian organized crime. That's why we got a dozen bodies on him.
Mac: Looks like it just went to a baker's dozen.

Mac: Walsh went out the window.
Sinclair: So he was just collateral damage. Just like the property clerk.
Mac: Dunbrook thought he could play us from the very beginning. He thought he could buy this town. Buy the support of the police department when he ended the Blue Flu. And his own brand of justice along with it. Now he's got us cornered. It's time to fight back.

Mac: We may be guilty of creating an uban legend, but there's no way this building is guilty of murder.
Danny: Alright. Well if the Empire State Building didn't do it, what did?

Mac: We're gonna need blueprints of that prison. Everything you can get your hands on. Electrical systems, service corridors, every single access point.
Stella: You really think we can do this?
Lindsay: What? What are you thinking?
Mac: We're gonna have to break Hawkes out of prison

Mac: Wealthy neighborhood. Rows and rows of million-dollar homes. Why'd the attackers choose this one?

Mac: What did the witness see?
Flack: Nothing. She heard a ruckus through her wall, then the gunshot, discovered him here.
Mac: She ran towards the sound of a gunshot? Must not be a New Yorker.
Flack: [grinning] She's from South Carolina. The whole building's full of students.

Mac: What kind of killer photographs his crime and then e-mails it to the cops?
Flack: A showoff. Someone who thinks he's smarter than us.
Mac: We're about to prove him wrong.

Mac: What kind of person makes a fake profile to have an online love affair with their own husband?
Lindsay: She must've been trying to catch Ron cheating.
Jo: More like entrapment.
Mac: We knew their marriage was in trouble. This takes it to a new level.

Mac: When one of our own is taken from us, we always get our man.

Mac: When the Towers fell and Claire died, it was the clearest definition of what is unjust and unfair in this world, and I was powerless to do anything about it.

Mac: Where'd you go after the fight?
Aaron Collins: To the halfway house, to make curfew. You don't believe me? You can ask the gestapo pigs who run the place.

Mac: Who's your source, Reed? Who told you about the carvings on the neck?
Reed: I don't know his name.
Mac: How do you get in touch with him?
Reed: He contacts me.
Mac: What's he look like?
Reed: I can't tell you that.
Mac: You can and you will.
Reed: Look, when I wanted a story, you stayed true to the code of your office and now I'm staying true to mine.
Mac: This is not a game. An innocent man is dead.
Reed: What are you talking about?
Mac: Your blog. You accused a driver named Jimmy of being the Cabbie Killer.
Reed: I didn't accuse anybody. I reported the information that I was given.
Mac: Without confirming it. Jimmy, the cabdriver was also known as Police Officer James Chameides. He was moonlighting as a cabbie out of Five Brothers Garage.
Reed: No, wait a minute. I thought Chameides was the work of the Cabbie Killer. He was, was, he was dumped from a cab.
Mac: His own cab. After he was brutally beaten and murdered by three men, vigilante justice. Now, where do you think they got the idea that Jimmy was the Cabbie Killer?
Reed: You're not blaming me for this guy's death.
Mac: I'm blaming you for putting a target on his back.

Mac: You are a very attractive woman and your husband was just an average guy. Would it be fair to say that you were more interested in a Green Card than a marriage certificate?
Flora Pollock: (tearing up) It would be offensive to say that.

Mac: You chose people who were vulnerable and broken. People you knew had nobody to question your motives. What's it like to live without a conscience?
Grace Chandler: It's like being rich. Something you probably know nothing about.
Mac: Putting people like you away for the rest of your life, doing good... that makes me rich. Something you probably know nothing about.
