Mac: (seeing the table set with a variety of foods) Tell me this is not one of your weird cravings.
Lindsay: Only for science.
Mac: You were looking for me?
Lindsay: I was hoping to offer you a little a snack.
Mac: Well let me guess. This is another one of your famous reconstructions.
Lindsay: Just put one of these berries in your mouth and swab it around for a couple of seconds.
Mac: Lindsay I'm your boss, not a guinea pig.
Lindsay: Mac, I'm pregnant. Just humour me.

Mac: (talks with Lindsay about leaving evidence unattended) You were in the lab with Danny. Inspector Shelby...
Lindsay: Oh, but Danny was right there. I mean, I'm sure that he put it away. (realizing she's caught) Oh, that's a bad excuse. Mac, I... I'm sorry. I know it's my responsibility. I know we're talking about evidence that could convict somebody of murder.
Mac: Lindsay, to tell you the truth, I'm more concerned about you.
Lindsay: I'm okay, Mac.
Mac: (sternly) You put up a good front, but whatever is or is not going on between you and Danny, you cannot let it affect your job.
Lindsay: I should never have gotten involved with somebody I work with. It was stupid, really stupid.

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

Mac: (To Danny) We did all we could forensically, but in the end, it was your brother who saved you.

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 Gillian Whitmore) Inspector, we're both very busy, so simply put, if you tracked me down to ask me to remove myself from the Mac Taylor murder investigation, I'm afraid you gotta endure this mediocre cup of coffee for nothing.

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

Mac: (to his team) We're going to work night and day to figure out exactly why this killer chose his victims, and were going to use that connection to catch him before the press gets wind of it and panics the whole damn city over some kind of compass killer. Or worse... before he adds another victim to the map.

Mac: (To Jo) Whatever you find, find it fast. The only thing keeping this case alive is Ali's statement.

Mac: (to Joe) You're under arrest for the murder of Derek James, Lauren Salinas, kidnapping and attempted murder of a crime scene investigator, armed robbery, grand theft auto, assault and battery. But most of all, for pissing me off.

Mac: (to John Cook) You might be a badass on your neighborhood block, but when you get on the cell block, you'll be just another punk who shot a little kid in the back.

Mac: (To Kid Rock) You know how many guilty people sing that same song?

Mac: (To Peyton) Look into my eyes because I need you to hear me. I can't promise I won't ever be hesitant ior cautious, but I am commited to making this work. trust me Peyton I dont want to lose you.

Mac: (toasting during dinner) Here's to a great team and to getting Hollis Eckhart off the streets.
Stella: Yes. And to reminding us that life is fleeting and we should hold on to the people we love while we can.

Mac: (upset with an abusive dad) I'd give a year's pay to have two minutes alone in this room with you, but since that's not gonna happen, I'll just tell you this. You're gonna go to a place where you're never going to hurt Jesse again.
