Don Flack: John Brennan calls the station house once a month. And anyone who answers the phone gets a story about how his wife was murdered, and the man responsible is still out there. And it breaks your heart. Because you don't have any answers for him. But what can you do? Tell me, on those Mondays, when you hung up the phone, what did you do? [Stella shakes her head a little] You can't do much. Because you are chasing bad guys, who are out there right now, and the evidence on those old cases gets cold, and the witnesses don't remember half of what they used to, and-
Stella Bonasera: You're right. But I just can't stop thinking that I should've done more to help her find her brother.
Don Flack: You took her calls every Monday. That's a lot.

Don Flack: Maybe it's me, but I don't get it. You get 80 laps jammed into that tiny car; 10 second pit stops... Where do you go to the bathroom?
Mac Taylor: You don't wanna know.

Don Flack: We got Vandemann locked up tight in protective custody.
Mac Taylor: He tell you anything more to his story?
Don Flack: Not yet, but once he has a hot meal, and realizes we're not out to kill him, he'll come around.

Dr. Sid Hammerback: I'll just say it straight: I think our vic may have been killed by... a vampire.

Flack [to Sam Harris]: It's going to be a while before your brother wakes up. So in the meantime, I'm going to need you to help me catch the man who did this to him. Think you can do that? [shows Sam a small size NYPD shirt to get changed into] Make a real cop out of you.

Flack: (looking around the store) This is certainly a step up from the place my Uncle Teddie used to pawn his cufflinks when he needed a drink.
Danny: (lauhgs a bit) Yeah. Bars and pawnshops recession-proof.
Flack: Guess so.

Flack: Can you imagine the burden that little guy was carrying around? 12 years old. He's protecting his older brother and his mother.
Stella: Still can't wrap my head around the fact that they thought robbing a bank was their only option.
Flack: Luckily the D.A. and the bank president agreed not to press charges. And money's been pouring in from the public. Should be enough to keep a roof over their head for at least a little while.

Flack: Debbie, before you make a complete ass of yourself, do me a favor: take a look right here.

Flack: Hey-o, Terrence! This has been fun and all, but you should probably get some new friends. Your boys are like walking parole violations. What's the matter, did I hurt your feelings? Did you get sensitive all of a sudd...? (Seeing Mac in the apartment)
Terrence: I ain't trying to have no cop convention up in here. But you two need some quality time, so I'm gonna give you all five minutes.

Flack: I have to ask. Two years nurturing someone back to health, getting to know them, watching them grow. How do you rationalize killing them?
Debbie Fallon: They're a cancer. Living in the street like dogs. Begging for change.
Grace Chandler: Leaving their feces and stench in boxes in doorways.
Debbie Fallon: How long do you think they would have lasted before you or some other cop found them dead? We took them off the street. We gave them two more good years.
Grace Chandler: Two years living in a Park Avenue apartment building. Wearing the best designer clothes and expensive jewelry. We gave them things, things they never could have imagined. Having a life they were never supposed to live. We gave them two more years. Two years they would have never had.
Flack: And the payment for that was their lives?

Flack: I'm sure this isn't the only cap with Derek Jeter's number on it floating around the city. Doesn't prove anything.
Stella: Well, it proves that Nicky was in the bank with a gun and a note.
Flack: Come on, Stella. Troy Castro robbed that bank and the only reason he hasn't confessed to it is 'cause he's dead.

Flack: I'm thinking our vic's wallet and jewelry were on someone's Christmas list.
Mac: Along with his life.

Flack: If you could go back to that moment, just you and him in that apartment, would you do it again? Would you stick the knife in his chest?
Deborah Carter: (reliving the stabbing & not caring) All 17 times. Regret's a waste of time, Detective.
Flack: Right. You can't change the past. Stand up, turn around. No matter how okay you think you are, when you close your eyes at night, it's gonna haunt you. (as he cuffs her)

Flack: My gut as a cop? Sam wants to help us, but he's too young and too messed up to remember what happened.
Danny: My gut as a CSI is that the wound was a through and through, so where's the blood spatter? Where are the impact marks? Where's the bullet?

Flack: The hotel manager said that the girls did not check in with them.
Hawkes: So the guys either met them at some point that night and they all went back to the hotel to continue the party.
Danny: Right, or they were the party. Hired to, erm, blow out the birthday boy's candle
