Lindsay: Mac, are those flowers on your desk also from 'nobody'?
Mac: (Chuckles) Lindsay, go.

Lindsay: The traditional weapon from Southern Africa is called a knob kerrie. It's a cross between a club and a walking stick.
Mac: Similar to the Shillelagh in Ireland, considered a gentleman's weapon.

Lindsay: These aren't like cop cars anymore, they're like spaceships.

Lindsay: Who called it in?
Adam: Couple from Iowa, in town to see Spider-Man on Broadway, after a walk in the park. Odds were pretty good they were going to see a dead body either way.

Lindsay: You mean to tell me that while I've been trying to get a lead out of an empty cardboard box, you've been here doing magic tricks?
Danny: Uh, it creates a diversion, helps me think.

Lisa Richards: Every now and then, a fan would stop him on the street, challenge him to a fight.
Jo: How would Ryan handle that?
Lisa Richards: He'd give them an autograph instead.

Lisa Richards: I don't watch Ryan fight anymore. Seeing him get hit is worse than someone hitting me. Hard to watch someone you love in pain.

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.

Mac Taylor: Here's to us. A grumpy old fireman with no personality and a... charismatic... charming cop who came together... to help to build something that will last forever.
Joe Vincent: Charismatic, my ass.

Mac Taylor: Hey, Jo.
Jo Danville: Yeah?
Mac Taylor: Measure twice, cut once.
Jo Danville: I know. I know. Look at everything again... every report, every crime scene photo. Answer's in there somewhere.

Mac Taylor: I'm going to the opera tonight. Claire, would you hand me one of those things?
Claire Taylor: No, who are you going to the opera with?
Mac Taylor: John from the Robbery Squad.
Claire Taylor: John from the Robbery Squad? You're going to the opera with John from the Robbery Squad?
Mac Taylor: Yeah, that's right, he's an opera buff. Claire, would you hand me...?
Claire Taylor: I've been asking you to take me to the opera for I... I... I don't even know how long, and now you're telling me that... (She finds two opera tickets in the cotton swabs container) Nicely done.
Mac Taylor: John from the Robbery Squad is going to be very disappointed.

Mac Taylor: I'm just imagining how cluttered that desk of yours must be now, now that you're the boss.
Jo Danville: Oh! Interim boss. It's your desk. Although I wish you could've seen their faces when I moved a few things in there. It was like I had just taken over Joe DiMaggio's locker.
(Both chuckle)

Mac Taylor: I'm sorry, I... I didn't, I didn't mean... I know you don't think that.

Mac (to Jo): Who do you see in this picture?
Jo: You, me, Sheldon, Danny, Lindsay.
Mac: How many lab techs?
Jo: Three. They were assigned to the scene.
Mac: The only people taking crime scene photos were Danny and Hawkes. We're all in the picture, including the techs... so who took that picture?
Jo: You're thinking the killer, and this photo was a message.
Mac: Someone who could get access to our cell phones and send us that photo, someone who wouldn't look out of place at the crime scene, who could gain entry to the evidence, someone who's playing "catch me if you can." Not only was our victim part of the crime lab, I'm thinking so was our killer.

Mac: (Checking out a postcard) It's blank.
Adam: Well, that's why I swabbed the stamp adhesive for DNA.
