(Mac has arrested Dr. Beaumont and he won't stop talking)
Mac: Dr Beaumont, you have the right to remain silent. Use it.

(Marty is consulting Danny over the phone about how to examine the victim)
Marty: Lucky you're not claustrophobic. Me? I do not like confined spaces.
Danny: Why'd you choose a career that puts you in a windowless room with dead bodies then?
Marty: Ladies love the degree.
Danny: 6 years of med school to become a player, eh?
Marty: No...I was already a player, Messer. I just needed the bank to pay for my Porsche.
Danny: You know what? I officially hate you right now, all right?
Marty: [laughing] You done?
Danny: Yup. Only thing abnormal about this guy is the blood leaking from his neck.

(Stella is found passed out on her apartment floor)
Mac: Stella. Stella. Stella!
Stella Bonasera: (wakes up)...Where's Frankie?

(Stella pleads with her ex-boyfriend, who has her captive in her apartment)
Stella: You caught me off balance. I do love you, Frankie, that statue you made for me was beautiful. I meant to answer your messages, really I did...
Frankie: (quietly) But you didn't. (Stella's face shows her dismay) You didn't answer my messages. You didn't call. That tape was a testament to our love and you spurned it. You don't love me. You're going to pay for not loving me.

[about id'ing their vic]
Hawkes: I'd say a homeless guy probably living where we found him, in the park.
Stella: Park Avenue, maybe. I've got a really nice pair of pants, a tailor-made shirt, fancy watch, traces of paint and lipstick on the shirt, I'd say he's a very wealthy guy.
Hawkes: Well, he must have found the clothes. The shoes never lie.
Stella: Yeah well, this little watch here is worth four or five grand, quite a find for a homeless guy.
Hawkes: Yeah.
Stella: Let me check missing persons. Someone notices when a guy with money doesn't come home.
Hawkes: The way I see it, homeless people are missing people.

[About the burn victim]
Angie: Buyer beware. Kandy was a gold digger. I just wanted her next lover to know all the facts. I gave her everything she wanted. And she burned me.
Mac: And someone did the same to her.

[About the burn victim]
Hawkes: Tattoo on the inner thigh, means eyes only, means our vic had a lover.
Marty: Lovers' spat? Things got a little heated?
Hawkes: Literally.

[Adam's examining fungal spores, and Danny walks in]
Adam: Hmmm. Aspergillus Sydowii.
Danny: I was just thinking about that.
Adam: It's the, uh...fungal spores found on Jennifer Fazotti's body.
Danny: Fungal spores. Says they're indigenous to the Sahara desert.
Adam: How does an African fungus end up on a murder victim in New York City?

[after hearing the suspect's statement]
Stella: Fitting in. You're going to do a lot of that. Let's say for the next...15 years.

[Flack starts breaking cigars in half]
Robert: Do you have any idea how much that costs?
Flack: Now? Nothing.
[Flack breaks another cigar]
Flack: Hey, Stell.
Stella: Yeah?
Flack: That smell Cuban to you?
[Stella sniffs the cigar]
Stella: Can't tell. Better break another one.

[Giving a toast to Aiden Burn who was killed while working as a private investigator]
Messer: To Aiden.
(as they are processing a vehicle)

[Lindsay and Mac are standing in front of a lube pit at a strip club]:
Mac Taylor: There might be some evidence in there.
Lindsay: Let me know what you find. [Mac gives her a look] I'll go get my boots. [Mac nods]

[Lindsay holds a shirt she ripped off a suspect who was trying to escape]
Danny: Nice collar, Montana.

[Lindsay is digging through a dumpster looking for evidence]
Lindsay: This new-girl stuff has really got to stop.
Mac: It's better than digging through tiger dung.
Lindsay: Funny.

[Lindsay is taking off her shoes before heading into a suspect's home]
Danny Messer: You don't have to do that.
Lindsay Monroe: I was taught that, if you show a little respect, you might get more than you came for.
Danny: You be good cop, I'll be bad cop.
Lindsay: I guess you didn't grow up with hardwood floors.
Danny: No, actually, Bronx Marble.
Lindsay: What's that?
Danny: Linoleum.
[Lindsay puts her shoes back on after the talk with the suspect]
Danny: I thought you were going to play good cop.
Lindsay: There's just something about that woman.
