The opening credits incorporate the show's old CSI:NY logo at the beginning of the sequence.
This episode is set on Sunday Sep 11th, 2011 which marks the 10th anniversary of the 9/11 terrorist attack on the World Trade Center and the Pentagon.
Through some flashbacks and other bits of information disclosed as the episode progresses, we get to know the characters' whereabouts on September 11th 2001.
-Shaving foam on Mac's ear triggers a memory of him shaving in the morning and sharing a beautiful moment with Claire where he invites her to the opera.
-A woman listening to music on the bus triggers a memory of Mac borrowing an earplug from Claire and listening to music together on their way to work. Mac got down from the bus first and that's the last time he got to see his late wife alive.
-The clock hitting 9'00am triggers a memory of Mac stating the time as he is about to question a suspect when he first learnt of the attack.
-The smoke rising from a sanitation truck triggers a memory of her watching a smoke column rise from the Pentagon building as she was working for the FBI.
-The badge number on Danny's uniform triggers a memory of the first time Flack met him, as he was helping out an injured woman get away from the debris and Danny rushed in from the opposite direction willing to help.
-A "John Doe" label being attached to a body triggers a memory of Sid attaching "John Doe" labels to 9/11 victims. Hawkes was giving a hand tending to the injured as was Mac bringing bodies to the emergency medical services.
-In present time we learn that he slept through it. He had gone out, had a few drinks and didn't wake up until 2pm. He has always been embarrassed and lied when asked about it. He joined the "bucket brigade" to help clean out the debris the next morning.
-In present time we learn that she was in Montana when 9/11 happened. She jumped on a local fire truck, arrived to NY a few days later and joined the "bucket brigade" as well.
Mac is working as an employee at the DNA division of Piper Laboratories, helping to develop new techniques in extracting DNA that might help identify the 1,121 victims from 9/11 that remain unidentified (his late wife Claire between them) among others.
Jo is currently the interim boss while Chief Sinclair fills Mac's position as Head of the lab.
Danny, as Sergeant Messer, is working in the street and no longer at the lab.
Mac together with Chief Ret. Joe Vincent (a fireman who lost a son on 9/11) has been working together on a project to build a granite wall of remembrance memorial in Brooklyn.
Goof: Flack's badge number (#9154) is not consistent with the one he's had in the past (either #8571 or #8620).
(NSYNC is playing in the radio as Mac shaves and cuts himself)
Claire: 911? Uh, my husband seems to be performing some sort of self-mutilation ceremony. Yeah, it seems to be inspired by one of those boy bands. I don't know, uh, hang on. She wants to know if you got a good look at them.
Claire: Well, five white guys and questionable sexual orientation. One of them has curly hair and this impossibly high voice.
Mac: I'm going to the opera tonight. Claire, would you hand me one of those things?
Claire: No, who are you going to the opera with?
Mac: John from the Robbery Squad.
Claire: John from the Robbery Squad? You're going to the opera with John from the Robbery Squad?
Mac: Yeah, that's right, he's an opera buff. Claire, would you hand me...?
Claire: 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: John from the Robbery Squad is going to be very disappointed.
Claire: (To Mac, the day she would die) What would you do without me?
Reporter: (Over TV set) Good morning, everyone. 68 degrees at 7:30am on this partly cloudy Sunday. The date is September 11, 2011, marking the tenth anniversary of the 9/11 attacks. Flags will fly at half-mast and a moment of silence will be observed at 8:46am as we pay tribute to the victims and the fallen heroes of that tragic day. We will never forget.
Adam: I need your signature on this, boss.
Jo: I told you not to call me that.
Adam: Well, whose signature do I need at the bottom of this report?
Adam: Then you're the boss.
Jo: Interim boss.
Adam: I'm not gonna call you interim boss.
Jo: Well, that's what I am, at least until Sinclair fills Mac's position.
Adam: (About Mac's belongings) I call dibs on the Reagan photo if he doesn't come pick up his stuff soon.
Flack: How often you keep the place open after 4:00 a.m.? Mr. Lannigan, I thought this might go without saying but I'm more interested in the body lying in front of your bar than what was going on inside.
Hannah McCray: You lost your wife on 9/11, right?
Mac: Yes, I did.
Hannah McCray: Did they...? Was she ever...?
Mac: No, no, she was never identified.
Hannah McCray: Was she the...?
Mac: Claire. Her name is Claire, and the victims are not just DNA profiles. They have names.
(Hannah grows silent)
Mac: I'm sorry, I... I didn't, I didn't mean... I know you don't think that.
Hannah McCray: Is that why you left the police department? To do DNA research that might help identify her?
Mac: No, I'm helping to develop new techniques in extracting DNA because 1,121 victims still remain unidentified. Those families don't have closure, and... I know what that feels like
Mac: Why are you here?
Hannah McCray: If I'm being honest, I'm not sure anymore. I joined the lab in January 2010, and we've identified one victim since then. One. In a year and a half.
Mac: If you saw what that means to that one victim's family, you'd never question why you do it.
Claire: This is crazy, Mac. There are still so many people inside.
Mac: Claire, look, I know you want to help. Listen to me. Just stay on the phone and get as far away as you can.
(Jet engine roaring)
Claire: Oh, my God.
TV Newswoman: Oh, my God! Another plane just hit the other tower. A second airplane just flew directly into the South Tower. This is obviously not an accident.
Mac: Claire? Claire! Claire!
Adam: (Imitating Jo) Well, uh, I'm just... so sorry, sir, you're just not the man who replaces Mac Taylor at the head of this crime lab. Yeah, not with that pocket protector and those silly Pee Wee Herman-looking glasses.
Adam: (Imitating the man) Uh, but, um, then why did Chief Sinclair want to interview me and have you show me around the lab?
Adam: (Imitating Jo) Well, that's probably because he's just got to make believe that Mac Taylor's never coming back. He doesn't even know the difference between a GCMS and a scanning electron microscope. Well, I'll tell you what, sweet thing, okay? I'm gonna introduce you to a bunch of people that you're never gonna be supervising...
Lindsay: There's something seriously wrong with you.
Adam: (Gasps) Awkward. How long were you there?
Lindsay: Pretty much the whole time.
Adam: (After being able to trace a cell phone) Oh! Who's the man? Me, that's who. What?!
Adam: When you're the man and you see that the interim boss is not happy with that answer, you dig a little deeper.
(Jo smiles amused)
(After arresting some perps by tracing a cell phone)
Flack: Got to love it.
Jo: It never hurts to have a confession.
Flack: That shouldn't be too difficult. Those two aren't exactly brain surgeons. They'll give it up. Hardest part might be keeping their names straight. The white guy's name is Mike Black. They call him White Mike. The black guy's name is Mike White. His street name is Black Mike.
Jo: I'll take Black Mike.
Flack: Great. I got Mike Black.
(Jo looks confused)
Flack: The white guy. Don't think about it. But trust me, it's right.
Flack: I can't imagine what that withdrawal thing feels like.
Mike Black: Kind of like a cop who can't get a donut.
Mike Black: I... I see what you're trying to do here. You've come up with this phony murder story, get me to be, like: "No, I didn't kill nobody," but then you trick me into admitting to the robbery.
Flack: You watch too much TV, Mike.
Flack: (About Mike Black) He's either an amazing liar... or I'm not as good at this as I think I am.
(Joe hangs up on Mac)
Mac: You better get that. He's called three times this morning.
Joe Vincent: Yeah, he's a persistent son of a bitch.
Joe Vincent: When my son Jimmy got on the PD, he was assigned to this precinct. The two of us would meet here every Sunday morning for breakfast. For the past ten years, uh, every Sunday I go to Mass and... then come back here to this counter alone. I... try to remember his voice... the cop-fireman banter, the love, respect we had for one another. Every Sunday that goes by, memory fades a bit. But... this is how I want to remember him.
Mac: Well, that's why we're doing this project, right, Joe? Keep those memories alive. And, uh... while I hate to admit it... it's been a real honour working with you on this project. I feel like I've found a friend for life.
Mac: 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 startles Jo as she is remembering the 9/11 events)
Mac: Hey, you okay?
Jo: I'm just daydreaming. Thank you for saving me the trip downtown.
Mac: Well, thanks for saving me the trip upstairs.
Jo: They'd love to see you.
Mac: I'd never get out of there.
Mac: I'm just imagining how cluttered that desk of yours must be now, now that you're the boss.
Jo: 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.
Jo: It was... but we both know I'm just keeping the seat warm for you until you come back.
Mac: I'm not coming back, Jo.
Mac: Hey, Jo.
Mac: Measure twice, cut once.
Jo: I know. I know. Look at everything again... every report, every crime scene photo. Answer's in there somewhere.
Jo: That ring around the blood spot is called skeletonization.
Flack: Why don't they just call it a ring?
Jo: Okay, that's it. Forget it. I give up.
Flack: Sorry, it would be much more interesting if you guys used smaller words.
(Soon after the Word Trade Center collapsed, Flack and Danny stumble upon each other)
Flack: Hey, buddy, you can't go down there.
Danny: It's okay, I'm on the job.
Flack: What's your name?
Danny: Messer. Danny Messer.
Flack: Listen to me, Messer. You don't need to go down...
Danny: No, I got to get down there and help!
Flack: Listen to me, Messer. They're all gone!
Danny: I want to go help these people!
Flack: They're all gone.
Joe Vincent: You lost your wife, I lost my son. It is what it is. There is no good way to let go of that.
Mac: We were both down there on that pile, Joe. Digging, searching, hoping. When we first met, I remember you telling me how moved you were at seeing some of the same faces, day in and day out, down there at the site. Everybody coming together to pitch in and help out. How inspired you were that so much evil and pain could be channeled into so much good. Celebrate that. Share that. You said you did it for the families. You're one of the families, too, Joe. Don't forget that.
Devon: (After confessing to having killed a man) I'll never forget the look on his face.
Jo: Wow. It's fitting that on a day like today, the image of an innocent man dying for no good reason will be etched in your mind for the rest of your life.
Jo: We've known each other for about a year now, Don. I have never told you this, but I think you're one hell of a detective.
Flack: Thanks, Jo.
Jo: You're welcome.
Flack: Jury's still out on you, interim boss.
(Adam is trying to get the tie knot right)
Lindsay: Do you need a hand?
Adam: No, I got it. Got it. Just got to...
Lindsay: By the time you're finished, it's gonna be the 20th anniversary.
Danny: (About Lindsay) Where's... Adam and, erm... what's-her-name?
Adam: Can I tell you something?
Lindsay: Sure. What's up?
Adam: I slept through it.
Lindsay: Through what?
Adam: 9/11. I've actually never told anybody that before. Just... too embarrassed, you know? And everyone always asks me, you know: "Where were you?" And... I would lie.
Adam: (About 9/11) I was asleep. You know, I went out the night before with a couple of my buddies, and we had a few too many drinks, and I didn't wake up till after 2:00. And by then, the entire world had changed. The next morning, I got up at 5:00 a.m., and I went down there, and... I stood behind a barricade with these construction workers for, like, 12 hours, you know, until they opened it up and let us clean up the debris.
Lindsay: So you joined the bucket brigade?
Lindsay: Me too.
Adam: I thought you were in Montana.
Lindsay: I was when it happened. I watched the whole thing on TV, feeling totally useless, and like I wanted to help, but they weren't letting planes in, obviously. And then I heard that trucks from all over the country were going to New York. So, I jumped on a local fire truck, and I got here a few days after. We might have been on the same line, never even knew it.
Mac: 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.
