Stella Bonasera: What makes someone want to run 26.2 miles anyway?

Stella: (to Lindsay) Size two will get you in.

Stella: Did the camera malfunction?
Danny: Either that or 5th Avenue's haunted.

Stella: It just happened. I was putting a piece of bloody glass into an evidence bag. It was still wet. It just broke, cut me. (quick flashback to cutting her arm) I had no idea at the time that Emery Gable was HIV-positive.
Mac: Stella, why didn't you tell me?
Stella: I thought I could handle it on my own. I'm scared, Mac, I know there are a lot of people living with AIDS, and I just... I don't think I have the strength to do that. I don't think I'm brave enough to wait for a cure.

Stella: Lemme guess. Tom?
Peeking Tom: The man, the myth.
Stella Bonasera Detective Bonasera. The law, the order.

Stella: Somebody kissed his ring. Lipstick kiss.
Flack: Maybe our Lancelot had a rendezvous with Guinevere at the park?

Stella: Verna Welke?
Trina: Yes?
Stella: I've come for the alien?

Stella: You can talk to me off the record, you know that, right?
Lindsay: What do you want me to say?
Stella: You left the crime scene Lindsay, I mean, I covered for you, but...
Lindsay: Yeah, thanks.
Stella: Look, if you have a problem you should tell someone, I'm just trying to help.
Lindsay: Well don't, OK? Just leave me alone.
Stella: Clearly I made a mistake about trying to be your friend here, so I'll be your boss: when you're requested at a crime scene you show up and you do your job. Speaking of your job, I expect to see you at the autopsy this afternoon.

Taurus Tevis: [Sees Mac] Yo. [Sees Flack] 'Sup, Blue?
[Flack gives him the nod] [about playing basketball in Harlem]

Tony DeLuca: The only reason I was with that girl was because I was doing Mandi a favor.
Detective Don Flack: Having sex with the hotel concierge was a favor?

Yuri Sokov: I'm an American citizen.
Detective Danny Messer: With a rap sheet as long as the Constitution.

(about a skateboard being used as a weapon)
Danny Messer: My mother always told me those things were dangerous.

(about the fallen-angel victim)
Flack: No ID on the vic. Could be a Michael or Gabriel. They say it's tough to make it in Manhattan. Heaven must be brutal.
Mac: Yeah.
Flack: Still checking Missing Persons and Nostradamus.

(about their cut up victim)
Stella: She was alive when he cut her in half.
Mac: Something tells me this girl wasn't a volunteer from the audience.

(about their victim in the tub)
Danny: So she comes in, drinks some champagne and takes a bath.
Peyton: Just like the fairy tale.
Mac: Only this Goldilocks isn't sleeping. She's dead.
