Don Flack: So, Camille Jordanson wasn't just stealing meds. She was also giving them fake meds in return. Pun intended: That's pretty sick.

Don Flack: This doesn't make any sense. This kid closed down te funeral home, but stayed in the embalming business.
Jo Danville: He kept it open for personal use. [reviews crime scene] No signs of struggle. So Isabel was probably unconscious when he laid her out here. So what did he do from there.
Lindsay Monroe: [opens door to closet] He dressed her. [takes out a dress] Vintage. Looks like it's from the fifties.
Don Flack: Hey, if we come across a little old lady skeleton in a wig and rocking chair down here, it's every man for himself.

Don Flack: Thought you had the night off.
Mac: My dinner date dumped me for a dead body.

Don Flack: Torres was the leader of El Pu�o so this was likely a hit by a rival gang.
Mac Taylor: That means El Pu�o's gonna want blood.
Jo Danville: From what I've heard, these aren't two-bit, three-block dope dealers.
Mac Taylor: Far from it. They control East Harlem.
Don Flack: Drug trafficking, extortion, murder for hire, name it. El Pu�o's a one-stop shop for all bad things.
Jo Danville: Whoever killed Torres is gonna have a mark on their head.
Mac Taylor: Well, we got to find them before the streets do, or it's going to be war.

Don Flack: We don't know who our killer is. We don't know who our victim is.
Jo Danville: And our crime scene could be anywhere in the world.

Don Flack: We got some whackadoo running around throwing acid in people's faces?
Mac Taylor: Not acid...lye.
Flack: All right. Well, I'll start with the nuts in this city and work my way up.

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.

Don Flack: What about the bag?
Arnold Vonley: Man, I'm a specialist. Strictly cash and jewelry only. I'm not risking my life for some sweaty gym socks.
Don Flack: How much did you get away with?
Arnold Vonley: 20 bucks. Plus the watch. Probably like 80 bucks, total.
Don Flack: I'm gonna be honest with you, Arnold. You're probably the dumbest mugger I've ever met.
Arnold Vonley: Why? What was in the bag?
Don Flack: Five million dollars. Those were some valuable gym socks.

Don Flack: What are you after?
Raymond Harris: Justice.

Don Flack: What the hell kinda car are you?

Don Flack: What's up?
Mac Taylor: You just killed two people: owner and an employee behind the counter.
Don Flack: That sounds like me.

Don Flack: You don't call, you don't write- I was beginning to think you were seeing other detectives, William.

Don Flack: You know, Mac... the uh, the Department decides to go through with their internal investigation, I'm gonna have to answer questions. All I know is what you told me when I got up to the top.
Mac Taylor: Like I told the DA, I did not toss Clay Dobson off that roof. This investigation is nothing but a big political show.
Flack: Yeah, regardless, the media's soaking the story up, and by the time they're done with it, your word may not be good enough, Mac.

Don Flack: You think Houdini knew the impact he would have on Mafia lingo?
Sheldon Hawkes: I'm sorry?
Don Flack: When they whack somebody, they say, "we made him do a Houdini". Do you think that would make him proud?
Sheldon Hawkes: Are we actually having this conversation?
Don Flack: Oh, I'm sorry. Can you explain the difference between DNA and RNA? Is that better, 'cause that's scintillating conversation right there.
Sheldon Hawkes: It would be if you knew the answer-
Rupert Flannigan: This is what your looking for, it has all three items you showed me in those photographs. You better return this though, it's a collector's item. I don't want to find out you two pulled a Houdini on me.
(Don walks away smirking)

Don Flack:[to Manny Ravarra] We're here about a homicide that was committed last night in Jamaica Estates. Couple was bludgeoned to :death.
Danny Messer: And we don't make you for it. In fact, we have an eyewitness who says it wasn't you.
Manny Ravarra: All right.
Danny Messer: But your cell mate, he says you did it. Said you were bragging about it.
Don Flack: But Owen Hicks is looking to get out from under a robbery charge that will most likely send him upstate for the next 15 years, so...
Danny Messer : Yeah, not the most reliable source. We figured we'd come here, lay our cards on the table, give you an opportunity to respond.
Manny Ravarra: Let me see if I got this right. My crackhead cell mate gives me up for a murder that an eyewitness says was committed by someone else, and you two drop by here to give me the opportunity to say that I didn't do nothing? I got that right?
Don Flack: What about it, Manny?
Manny Ravarra: What about it? Sometimes crackheads actually tell the truth.
Danny Messer: So what are you saying?
Manny Ravarra: I'm saying your eyewitness is wrong. I killed that couple.
