Jules Roday: He didn't do it. He doesn't have it in him to do something like this.
Don Flack: Okay, Jules, I'm going to let you in on a little secret. Everyone has it in them to do something like this. Everyone.
Jules Roday: No. Not Billy.
Don Flack: How long have you been going out?
Jules Roday: Five months.
Don Flack: Five months? I usually like to wait at least six months before I can attest to somebody's lack of homicidal tendencies.
Jules Roday: You're kind of a bitch, you know that?
[Flack smiles]

Julie Rollins: You have to understand, my husband died last year, Heather was all I had.
Mac Taylor: There is nothing about this that I understand.

Kate Price: you know why I remember you, Lindsey? The day that we met at group, before you and me spoke. You kept checking your watch. You just couldn't wait to get out of there. I don't blame you. It wasn't like we wanted to be there either.

Kelly Lindgren: This is Joel?
Detective Don Flack: What, you don't recognize him with half his face blown off?

Kelly Rose: I opened this store for fans of the macabre.
Danny: Right. Selling locks of Charlie Manson's hair.

Kenneth Bamford: I paint a lot of girls. Maybe you're interested.
Stella: I'm only interested in finding out what happened to this one.(holding the picture) We didn't pick up significant radioactive trace on you or your studio. Did you make contact with her in any other way?
Kenneth Bamford: (smiling) I like the way you think, but no. She wasn't my type.

Kenny Hexton: (Giving Wes a gun) It's time to lighten the load.
Wes Dillon: (Knocks Kenny with the gun) You're sick, you know that? (He kicks Kenny repeatedly) Killing little kids is where we part ways.

Kevin Murray: At least tell me what he said?
Mac: What who said?
Kevin Murray: The guy about me dying tomorrow.
Mac: Well, I'm sorry, that's part of an ongoing investigation.
Kevin Murray: This morning you said he'd been to the future. Did he say how or where or when I'd be killed?
Mac: Again, unless you have some information to share that might shed some light on our victim, I don't see what else we can do for you.
Kevin Murray: How about guaranteeing me I'm still alive in 24 hours!

Lieutenant Horatio Caine: Mac, heard there was a break in the case?
Det. Mac Taylor: Stella already has you on speed dial. I thought you had to duck out on personal business?
Lieutenant Horatio Caine: I got an extension.
Det. Mac Taylor: Good news for both of us.

Lieutenant Horatio Caine: [cuffing him] Vincent Rosetti, you're under arrest for the murder of Lydia Johnson.
Det. Stella Bonasera: And that's just the charge in Florida.
Vincent Rosetti: Selling your weapon in Union Square to a stranger, Vincent. That wasn't too bright, was it?
Vincent Rosetti: No way I've been in Attaca the last six months on a stolen property bid.
Det. Stella Bonasera: Yeah we know that's where you met up with Henry Darius.
Vincent Rosetti: So I was in lockdown with him, big deal.
Lieutenant Horatio Caine: On the contrary, Vincent. It is a big deal.

Lindsay Monroe Prints were a bust. CODIS was about as helpful as FEMA.

Lindsay Monroe: $5 million worth of gems just fall in this guy's lap.
Jo Danville: And there he is, thinking it's the luckiest day of his life.
Mac Taylor: Turns out to be anything but.

Lindsay Monroe: (about Billy Travers) He was either extremely careful or we have to consider that he didn't do this.
Mac Taylor: At the scene, I thought that might be the only chance to talk to her. When they said there was no forced entry, that prompted me to show her a photo of her family.
Lindsay Monroe: And she was responsive, right?
Mac Taylor: She was. She looked me in the eye and understood me. But maybe I pushed too hard in the moment.

Lindsay Monroe: [walks in to see some of team watching a porn-esque home movie] Footage from your 30th birthday, Messer?
Danny Messer: Walrus documentary, actually.
Sheldon Hawkes: It's Tara Stansfield, our vic from the park.
Lindsay Monroe: Who's the other walrus?

Lindsay Monroe: A few of these and a laptop, and she's able to write, record her own music, post it online for millions of people to hear, and then text and video-chat with God knows how many more.
Danny Messer: Well, that's great, but how long before more is too much?
Lindsay Monroe: (laughs) I don't know, but... you know, we already opened the 21st century, Danny. I think it's too late to send it back.
Danny Messer: Yeah, well, you're probably right about that, but just to be clear, though, Lucy is never going near a computer, okay? Just, ever.
Lindsay Monroe: Okay. But she does have, uh, a laptop lab at her preschool, and she can use my iPhone better than I can.
Danny Messer: Damn it.
