- Detective Danny Messer: [after chasing a suspect down a road and up a fence] There's one thing I hate more than running - leaping. You're not my favorite person today. Come on.
- Aiden Burn: How does a potential shortstop become a crime scene investigator?
- Detective Danny Messer: That's real easy. Get into a fight, break your wrist, and then graduate from the police academy top of my class.
- [last lines]
- Quinn Sullivan: So, why'd you help me?
- Detective Mac Taylor: Because you told me the truth.
- Quinn Sullivan: You know there'll be a civil trial.
- Detective Mac Taylor: And this time, the evidence will come to the rescue. Mr. Sullivan, my job is to collect evidence and, without bias or expectation, provide an answer. I don't usually hope the suspect is innocent or guilty. This time... it was different. This time, I wanted the evidence on that hammer to be wrong. I liked the possibility of... changing everything.
- Quinn Sullivan: Me, too.
- Detective Mac Taylor: When the towers fell, and Claire died, it was the clearest definition of what is unjust and unfair in this world, and I was powerless to do anything about it.
- Detective Stella Bonasera: Why haven't you taken your wedding ring off?
- Detective Mac Taylor: Because, uh, I don't know. I don't want to.
- [examining the woman who was hit by a car]
- Detective Mac Taylor: No clothes, no shoes, no handbag, just lace.
- Detective Stella Bonasera: If this is the new look for spring, you can count me out.
- [Stella is speaking in Greek]
- Detective Stella Bonasera: Pou eisai esi vre file? Skeftesei kat kai ksero pou thelis na me to pis.
- Detective Mac Taylor: And in English?
- Detective Stella Bonasera: What the hell's buggin' ya Mac?
- Detective Mac Taylor: Sounds so much better in Greek.
- Detective Stella Bonasera: [Smiles] Yeah, most things do.
- [in parking garage of Yankee baseball stadium]
- Aiden Burn: [looking at victim's driver's license] Name's Gilbert Novotny... Brookline, Massachusetts
- Detective Stella Bonasera: A Boston fan in the Bronx. That's brave.
- Detective Danny Messer: Or stupid. Very stupid. Boston's tough. New York better get it together.
- Dr. Sheldon Hawkes: Now, these abrasions were suffered while running.
- Detective Stella Bonasera: Mm-hmm.
- Dr. Sheldon Hawkes: But... these here, tiny puncture wounds on her soles. I can't imagine what she was doing.
- Detective Stella Bonasera: Do they have anything to do with cause of death?
- Dr. Sheldon Hawkes: No. I had Tox run a screen, results were negative. Margo Trent died because she was hit by a truck, plain and simple.
- Detective Stella Bonasera: Okay. So this is no longer a case for Homicide. Flack will want to pursue a suspect for possible rape and assault charges. Why don't you collect a sex kit, send it over to DNA.
- [Stella's pager beeps]
- Detective Stella Bonasera: Oh. Dispatch. You know, I have a feeling it's going to be very busy day.
- Dr. Sheldon Hawkes: Mm-hmm.
- Detective Stella Bonasera: Want to switch jobs?
- Dr. Sheldon Hawkes: Oh, yeah, sure.
- [Hawkes points to a cadaver, and holds out a pair of saws]
- Dr. Sheldon Hawkes: You'll be cutting off that guy's right arm and left leg.
- Detective Stella Bonasera: [smirks] I'm leaving now.
- Quinn Sullivan: [quoting Mac] "A small mistake can be significant enough to change everything that follows."
- Detective Mac Taylor: Mr. Sullivan, if you have something to tell me, say it now.
- Quinn Sullivan: I lost it. I don't know where I dropped it, I don't know when... but I figured if I told the truth... if I told them I owned it, it was as good as pleading guilty. But what if the hammer was mine?
- Detective Mac Taylor: That changes everything.
- Detective Stella Bonasera: If you're looking into the Alissa Danville case for mistakes, I expect to be consulted.
- Detective Mac Taylor: I wasn't looking...
- Detective Stella Bonasera: Mac, the murder weapon was in the alley with his DNA on it. What else did you expect to find?
- Detective Mac Taylor: Well, for one, we didn't take a substrate control sample on the murder weapon.
- Detective Stella Bonasera: That's because Sullivan claimed that the hammer wasn't his. In that kind of a case, not taking a control sample is standard procedure.
- Detective Mac Taylor: Well, maybe that should change, because finding someone's DNA on a murder weapon shouldn't automatically make them guilty.
- Detective Stella Bonasera: It doesn't. Let's just consider the facts in this case, all right? His coworker testified that every time Alissa Danville walked past the construction site, Sullivan stopped and watched her go by. Then there's the hammer. It was issued to every employee of Luxwell Construction Company. Every single hammer was accounted for except for Quinn Sullivan's. And yet he claims that the hammer we found at the crime scene with his DNA on it wasn't his.
- Detective Mac Taylor: He told me it was.
- Detective Stella Bonasera: You went to see him.
- Detective Mac Taylor: Mm-hmm. He now claims the hammer, but he still sticks to his story that he didn't kill Alissa Danville.
- Detective Stella Bonasera: You believe him?
- Detective Mac Taylor: I want to. Stella, if the hammer was his, his DNA could have already been on it. DNA from epithelials he shed from normal, everyday use. Source attribution, Stella. It's a viable possibility the victim's blood was spattered on top of Sullivan's epithelials. When we tested the blood for DNA, we got a match for both the victim and Sullivan.
- Detective Stella Bonasera: Well, if we had known that it was Sullivan's hammer, it wouldn't have changed our test results.
- [Mac gives Stella a look, and realization dawns on her]
- Detective Stella Bonasera: But it might have changed our conclusion.
- Dr. Sheldon Hawkes: [hands Stella a spleen from a victim] I've got something else for you.
- Detective Stella Bonasera: Don't tell me you're going to make me hold something else.
- [suspect explaining what provoked him to kill fan at baseball stadium]
- Suspect: They showed our section on the Jumbotron, and he leaned over and kissed me, right on the mouth. In front of all those people. I can take a joke, but that was too far. I don't like looking like a fool.
- Detective Danny Messer: You got all hot under the collar over a little smooch?
