Mac Taylor: (right before sending them to a bar in search of a perp) I hope Jo and Flack are thirsty.

Mac Taylor: (hands Danny a lighter) You want to do the honors?
Danny Messer: Are you lighting your arm on fire in the name of science?
Mac Taylor: What other job allows you to set your boss on fire? Going once, going twice...
Danny Messer: (takes the lighter) Sold, but if you go up in flames, I get your office?

Mac Taylor: (looking at Lindsay) Put your affinity for bugs to work
Lindsay: (sheepishly) I don't actually have an affinity for bugs.
Mac: The beetles were the first on the scene, we need to know what they know. (points at Lindsay) And no eating.

Mac Taylor: (Speaking for his female avatar) Hi. I like the name. (pause) I love waterfalls, don't you?
Stella Bonasera: (Laughing) Oh, my God.
Mac Taylor: What?
Stella Bonasera: You have no game whatsoever.
Mac Taylor: Look, I don't need a backseat avatar.
Stella: All right, then move over. Come on. Before your suspect bails. (takes the headset in his place on the game) Hey, Don. Sorry about that. I was, uh, distracted by a phone call. My name's Taylor. What do you say we get outta here and go for a walk?

Mac Taylor: (To Kenny Hexton) That can't be easy. Being on the run like that. All that picking up, moving. New town, new faces. None of that changes once you're on the inside. Not if I have anything to say about it, and I will.

Mac Taylor: (to Luther Devarro) A handshake used to mean something. An officer was shot today, and a civilian wounded. The ammo we found had your crew's signature on it. When a guy like you gets released from prison a week before people start getting shot, I don't believe it's coincidence.

Mac Taylor: [about mosquitoes] Only the female of the species bite.
Stella: Good for her!
Mac: Did you know that Hawkes is a walking encyclopedia of tidbit information?
Stella: That's good. Now you can go to him instead of Google.

Mac Taylor: [To Hawkes] You are the man of many talents.
Hawkes: You know, there was this time I wanted to be a sculptor. [Mac looks suprised]

Mac Taylor: [to Stella] That's what I like about you; you always get the details right.

Mac Taylor: [to Stella] Use your head, not your heart.

Mac Taylor: Adam, you all right?
Adam Ross: I've been better.
Mac Taylor: You want to talk about it?
Adam Ross: What's there to say? He strangled her, she died... end of transmission. I'm gonna wait in the car.

Mac Taylor: and this would explain the transfer of the F.Lindsay go to the Archford Academy website. I wanna know what exams are scheduled for today.
Lindsay Monroe: AP World History
Mac Taylor: Looks like Olivia Prescott might have caught a cheater.

Mac Taylor: Do you know this man?
Dot-com: Yeah, that's Jesse Lewis. Why, did he do something wrong?
Don Flack: Yeah. He stepped in front of a gun while somebody else was pulling the trigger.

Mac Taylor: Don't quote me on this, Lindsay, but sometimes -- [lifts the head of the vic off the body] -- not everything's connected.

Mac Taylor: For the last four months, it has been my honour and privilege to be a part of something so important and that I am truly proud of. To contribute a little bit to so many who lost so much. These 417 first responders, the portraits of their faces etched in granite and honored here on this Brooklyn Wall of Remembrance, will live in our hearts forever. Ten years have passed since that tragic day. Many of us here have been personally affected and share a loss. And so once more, we pause and we pray, and we will continue to do so as each anniversary passes. In helping to finish this memorial, I've met some truly remarkable people. And we've had the opportunity to meet with many of you who generously shared your thoughts and feelings on how best to remember these fallen heroes who demonstrated such unmitigated courage and selflessness. The effort to build this wall of remembrance has been a great blessing, as we attempt to heal our broken hearts. And here today we gather, a people united not only in our grief, but in our resolve to stand together as one family of Americans. God bless these brave souls who served so selflessly. They will never be forgotten.
