Adam Ross [to Hawkes]: Hey, what do you know about Fishzilla?
Sheldon Hawkes: Sounds like a bad name for a monster movie.
Adam Ross: Close... it's the nickname of that weird little thing I found at the bottom of the mezcal bottle. Yeah, its real name is snakehead fish, all right, and it's illegal in all 50 States.
Sheldon Hawkes: Then it couldn't have been that easy to get. How did it end up at our crime scene?
Adam Ross: Uh, I don't know, maybe it was left as a message. You know, these things are pretty vicious. They eat everything, even their own kind.
Sheldon Hawkes: The message could be in the name. Snakehead... reference to the Mambas?
Adam Ross: I'm trying to track down where you can buy these things and then maybe I can figure out who purchased it.
Sheldon Hawkes: How are you going to track it down if it's illegal and off the books?
Adam Ross: I... I know a guy that knows a guy that... knows a guy that knows another guy.

Adam Ross: (to Owen Hicks; impersonating a polygraph examiner)I understand there's a question to the veracity of certain statements that you may or may not have made and or heard during your confinement in the fine institution known as Rikers Island. Is that correct?
Owen Hicks: I have no idea what the hell you just said, man.
Adam Ross: Are you playing games with me, son?
Owen Hicks: No, I'm not playing games...!
Adam Ross: Because any heretofore games will not be tolerated. Okay?
[As Jo and Danny witness Adam trying to get a confession out of Owen Hicks]
Jo Danville: How long do you give him?
Danny Messer: Well, if Adam remembers to plug the damn thing in, I don't think he gets past the first question.
Jo Danville: First question? No way it gets that far.
[Back in the interrogation room]
Adam Ross: (to Owen Hicks as he gets him ready for the polygraph) This simply measures your blood pressure while the test is being administered. The information then relays to the pen thingy which will go haywire if you're full of... if you're being untruthful. And, based on the amount of sweat that's accumulated on your forehead... gross... is more than likely.

Adam Ross: Hey Mac, if a bird spits on you do you think it's the same good luck as whe-
Mac Taylor: Figure it out, Adam.

Adam Ross: I feel like I've forgotten everything, like I-I can't remember any of the details.
Jo Danville: Well, that's not uncommon, when the brain experiences trauma. Sometimes it locks up. But not to worry, cause I always carry a spare set of keys.

Adam Ross: I shared the final moments of Sass Dumonde's life. I, I... I heard her music. I... I saw her joy. I-I... maybe even fell in love a little. And then, three minutes later, it was... it was just over.
Jo Danville: When you cross paths with people like that, it's hard not to stop in your tracks. But believe me when I tell you... none of what you're doing now will bring her back. It will only bring you down.
Adam Ross: What do I do now, though?
Jo Danville: Go home. Go to bed. Come back in the morning ready to do what's right.

Adam Ross: I've seen everything in these bottles: worms, spiders, live scorpions... whose venom, by the way, okay, makes this drink an hallucinogenic. [Hawkes makes a face] Uh, well, I... I... I don't know anything about that.

Adam Ross: It's got all the auditory markers of an ass dial. You know, when your phone's in your back pocket and you make a call that you don't even know you're making. For instance, okay... my ass dialled my girlfriend once when I was out at a bar with some friends. Left, like, a 15-minute message, you know? I mean, it would've been really funny, except we were talking about her the whole time, and...
Mac Taylor: That's how she became your ex-girlfriend?
Adam Ross: Well... yeah.
Mac Taylor: Clear out the ambient sound, see if there's anything useful underneath, and call me when you got something. With your fingers, not your ass.

Adam Ross: Mac! You gotta come back to the lab.
Mac Taylor: What? Why?
Adam Ross: Because... because I think I just saw a woman get murdered.

Adam Ross: Our fish smuggler remembers a tough-looking Puerto Rican guy buying from him.
Sheldon Hawkes: He get a name?
Adam Ross: No, but he did specifically ask for three snakeheads.
Sheldon Hawkes: So our killer asked for three, and only two have been used. That's pretty simple math.
Adam Ross: Which leaves one more victim yet to be determined.

Adam Ross: The new voice mail was left using a second prepaid phone and just like numero uno, right, the SIM card was used once and then deactivated.
Lindsay Monroe: So Mrs. Harris' mystery caller is dumping phones as he goes.
Adam Ross: Sure looks that way. So, I compared the serial numbers on both the cards and guess what?
Mac Taylor: They were sequential?
Adam Ross: Yeah. Perp's not as smart as he thinks. He bought both the phones at the same store at the same time.
Mac Taylor: He alluded to a final message in the second voice mail.
Lindsay Monroe: So to leave it, he'd need a third phone which might still be active.

Adam Ross: What would you do?
Danny Messer: What would I do what?
Adam Ross: You know, if you found millions of dollars of gems in the street?
Danny Messer: Give 'em back.
Adam Ross: Oh, come on, guy. You wouldn't keep some?
Danny Messer: Why, would you?
Adam Ross: No, no, no, I... I'd give 'em back. Mostly... I mean... maybe keep one or two.
Danny Messer: Know what happens to people that take things that don't belong to them, right?
Adam Ross: No.
Danny Messer: Other people are getting hurt. Doc! Come here, we got an ethical debate going on, and Adam is failing miserably. What do you do if you come across a fortune of precious gems that don't belong to you?
Sheldon Hawkes: I'd give them to the guy with the knife to my throat.

Allison Scott [to Jo]: Don't you dare talk to me about grief, because my fiancé died in my arms.
Jo Danville: You're absolutely right, Allison, that was a terrible tragedy. I can only imagine the anger you felt. God himself couldn't save someone who wanted to hurt my family. I would hunt them down. I would make them suffer like they had never suffered before. I would need them to feel the unrelenting pain that I felt. But what if I was wrong? What if I hurt the wrong person? I could never live with myself.

Annie Cartland: I got what the system couldn't. Justice.
Mac Taylor: What you got was retribution.
Annie Cartland: Aren't they the same thing?
Mac Taylor: Not even close.

Bill Hunt: Not a day went by that I didn't think of turning myself in.
Mac Taylor: But you didn't
Bill Hunt: It wouldn't have made a difference.
Mac Taylor: It would have to me.

Billy Travers [after his mother identifies him as the one who beat her and killed her husband]: I don't understand. Why would she do this to me?
Jo Danville: Do this to you? Maybe because you beat her within an inch of her life.
Billy Travers: I wasn't even at the house. I haven't been home in over a month.
