Mac Taylor: The bodega was just around the corner. She [Olivia] went to get you some aspirin.
Natalie Dalton: And when I woke up a couple hours later, she was gone. I went through the entire building, knocked on every door, went through the streets screaming her name. I haven't had a drink since that night. That's what it took to open my eyes. But it was too late.
Mac Taylor: It's never too late.

Mac Taylor: This case has been sitting on the edge of my desk for the last nine years.
Don Flack: You got a new lead?
Mac Taylor: No.
Don Flack: Is the chif asking about it?
Mac Taylor: Nope.
Don Flack: Then, whats up? Why you looking into it now?
Mac Taylor: No reason.

Mac Taylor: This writing style is very unique. Look at the I's. Exaggerated slant. Alternating capital and lowercase letters between words. Someone may be able to recognize it.
Adam Ross: I'm not sure I follow.
Mac Taylor: We use it like a missing persons billboard. Instead of a face, we use this. 'If you recognize the handwriting, call the NYPD tips line.' That kind of thing. See? Out of the box thinking. Get it out to every media source you can think of. I want it on electronic billboards, too.
Adam Ross: All over the state?
Mac Taylor: The country.

Mac Taylor: Three dead bodies isn't the kind of buzz you want.

Mac Taylor: Uncovering mistakes made by your lab and alerting defense counsel was part of your oath. Still is.
Jo Danville: Tell that to Senator Matthews. I still get letters from him blaming me for the outcome of his daughter's case. The mistake I uncovered was made by a guy named Frank Waters. Impeccable reputation. I worked with Frank Waters for 12 years, Mac. I went to his wedding, his kids' birthdays. So when I discovered he destroyed a document detailing a mistake he made interpreting DNA results, trust became just another word and Serena Matthews' rapist went free.
Mac Taylor: You had to make it public.
Jo Danville: It was a decision I don't regret making and I'd make it again.
Mac Taylor: Jo, my team does not sacrifice integrity for a desired result. Now that you're part of it, I promise you you'll never have to make that kind of decision again, okay?

Mac Taylor: We processed this thing when the crime occurred and we never got a second donor. Why would it be different now?
Sheldon Hawkes: Well, I used a different genetic analyzer. Every instrument varies in sensitivity. If I ran it through a third one might not pick it up but this one did. Machines. Sometimes there's no rational explanation for why they do what they do.

Mac Taylor: What am I doing? How much longer can I do this?
Jo Danville: So that's why you went back to the bodega homicide, the last unsolved case. You wanted to see if you could find some closure.
Mac Taylor: I've done a lot of good.
Jo Danville: Yeah.
Mac Taylor: Maybe I've done my part.

Mac Taylor: What happened here Don?
Don Flack: This was a truck party gone bad. It's the latest craze in afterhours entertainment. They convert tractor trailers into exclusive nightclubs. Times and locations are spread among the social networks.
Mac Taylor: I'm assming this one didn't start at the bottom of the Hudson?
Jo Danville: I thought the truck was not supposed to move once the party started.
Don Flack: It's not.
Mac Taylor: So who moved it?
Don Flack: Couple cabbies nearly got runover, but they didn't get a good look of the drivers face. They did say that he accelerated through the fence. The abscence of skid marks confirms that there was no breaking.
Mac Taylor: Driver could've drowned. Or still be among the survivors.
Jo Danville: we have divers in the water looking for more bodies and the others are being transported to the precint for questioning.
Don Flack: My guess; driver saw that river coming, jumped before splash down, then got the hell out of dodge.
Mac Taylor: Either way, looks like crashing this party wasn't an accident.

Mac Taylor: What were they after?
Don Flack: Cash, stock certificates and get this. $5 million in precious gems and jewellery. Carson was keeping them for a client in his private safe.
Mac Taylor: It's not so safe after all.

Mac Taylor: What were you thinking, Paul? You were getting even? That killing your parents was somehow gonna settle the score for them testifying against you?
Paul Benson: I was just a kid.
Mac Taylor: You were 18 years old. You were old enough to be held accountable for your actions.
Paul Benson: They betrayed me.
Mac Taylor: No, no. You betrayed them. You think it was easy for your parents to do what they did? Your girlfriend, Sarah... they were just supposed to let her go through life knowing you raped her and got away with it?

Mac Taylor: You always walked the line, Bill, but I never thought you'd cross it.

Mac Taylor: You want to kill me, Harris? Kill me. Here I am. Make a move.
Raymond Harris: Then there wouldn't be any surprises. Where's the fun in that?

Mac Taylor: You're a man of reason, Luther. Come out, give yourself up.
Luther Devarro: It's too late for me, Detective. I never intended to create something violent. It was never about drugs and guns, money and power. When they put me away, all that changed. Torres, Lisa and my brother! Took what I created, just a group of guys trying to watch each other's back, taking care of their neighbourhood and they turned it into some criminal enterprise.

Mitch: ...clothes on her back, food in her mouth, and she runs away? Huh?! That's how she repays me?!
Don Flack: Settle down, Mother Theresa.

Mrs. Anderson: (to Flack about her son Craig) His first words were Bird and McHale.
Don Flack: Mine were cookie and cake.
