Luke Blade: [talking about his next "trick"] And most importantly, it has be performed by a highly pissed off professional!

Luke Blade: [to Mac and Danny] If that's all detectives, I'm gonna go light myself on fire.

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.
[in the wine vault]

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: I think we just found our prime suspect.
Don Flack: I love this job.
(viewing the store surveillance tape as a shimmer walks across the screen)

Mac Taylor: Science is our integrity.

Mac Taylor: The way I feel has never affected the way I do my job.
Don Flack: My weakness, I guess. Every hood Truby ever collared is going to be angling for a get-out-of-jail-free pass. Clay Dobson was just the first in line.
Mac: You having a good time, saying I told you so?
Flack: No.

Mac Taylor: We want a reference sample.
Tony DeLuca: What, so you can put it on some government database? Forget it, I know my rights.
Flack: Yeah, we've got rights, too--they're called warrants.

Mac Taylor: You ready for the answer?
Stella: Whatever the outcome, I am bound and determined to live every day to the fullest.

Mac: (about his father) He spent the last eight months in bed on a feeding tube. Eventually, the medicine didn't do anything for the pain, so one day, he asked me...he begged me to end it for him. I couldn't do it.
Hawkes: You made the right choice.
[Mac looks unsure]

Mac: (enters his office to see Stella and Lindsay waiting for him) Something wrong?
Stella: Lindsay's gonna take off for a little while.
Mac: When?
Lindsay: I leave tomorrow for Montana. A couple of months ago I got a call from the Bozeman's prosecutors office. They apprehend a suspect who was wanted in a multiple homicide ten years ago. Four girls. They were uh... they were friends of mine. I was the only witness.
Mac: And the only survivor as I remember.
Stella: They want her to testify.
Lindsay: I still see their faces. My friends faces. The mothers' faces... I don't know what I'm more scared of. Standing in front of the monster who did this... or seeing those faces. (she gets up as Stella gives her a hug)
Stella: Hey, you take care of youself, kiddo.
Lindsay: Thanks.
Mac: (gives Lindsay a hug) You're tough, Lindsay. You'll pull through this.

Mac: (looking around the work firm) Nice place, Dobson, looks like your father's doing quite well for himself.
Clay Dobson: Detective Taylor, I was just about to send you a fruit basket. You're the reason I'm out of jail, indirectly, of course. If you're looking for an architect, I think we might be a little out of your price range.

Mac: (thinking) Will you walk into my parlor?
Hawkes: Said the spider to the fly.

Mac: (to Flack) The cop who did this, I hope he goes away for a very long time, because he disgraced the badge we both wear.

Mac: (To Hawkes) Shane Casey, he's coming after you.
