Stella Bonasera: When are these killers ever going to learn? You never leave a paper trail.

Stella Bonasera: When you were a little kid, did you ever tie a towel around your neck, pretend to be a superhero. A little Mac-man?
Mac Taylor: Seargent Rock. You couldn't get me out of fatigues when I was a kid.

Stella Bonasera: You think I'm trying too hard?
Don Flack: We all have a Marina Garito, Stella.
[Stella nods for him to tell him]

Stella: [Laughs] Well, Detective Angell just got me a court order to pull all the patient files and talk to the students directly. I'm hoping that this will give us an I.D. on the perp.
Danny: Fantastic. We got horny college kids and horny mammals. You wanna trade?
Stella: Mammals?
Danny: Prehistoric, to be exact.

Stella: Son of a bitch!
Mark Stutz: Makes you want to murder 'em, don't it?
Det. Stella Bonasera: [Stella doesn't respond to his comment] Get in the car.

Stella: (about Carolyn) She is not telling the truth.
Mac: She is terrified.
Detective Gillian Whitford: She should be. You know about an hour ago this place was probably filled with at least 30 young girls just like her from all over. Eastern Europe, Latin America. They took their big dreams and now they're living a very real nightmare: they're sex slaves. Being beaten, drugged... who knows what else.

Stella: (about George Kolavos) The man is taunting me, Mac. He sent me a dead rat as a message. Put yourself in my shoes.
Mac: Try stepping into mine. I'm in charge of this lab, responsible for everyone and everything that happens here. I admire your passion Stella but what you did is reckless. And more importantly, it could compromise any future criminal prosecution.
Stella: What I'm doing is perfectly legal!
Mac: And contrary to the policies of this lab and this department!

Stella: (about her lecture) I keep trying to remember the faces, and I just can't. It's all such a blur.
Professor Papakota: Well, if it's any consolation, I have been doing this... for over 30 years. You never remember the faces. Well... maybe a few.
Stella: It's just so disturbing to think that someone would attend one of my lectures just to learn how to get away with murder.
Professor Papakota: What students take away from a class is up to them, Stella. You cannot blame yourself.

Stella: (about the evidence) Turns out it's an experimental sexual enhancement drug, only available in clinical trials.
Danny: Don't look at me, I don't need it.
Stella: You're too old anyway. It's currently being tested on students at Chelsea University's health center.
Danny: Argh, it's like throwing gas on a raging hormonal fire.

Stella: (as he looks on at the interigations) Sam, you were next.
Sam Baker: What?
Stella: Your life was insured for over $5 million dollars. In order to become a legitimate beneficiary, Debbie called herself your fiance in all of the paperwork.
Sam Baker: I can't believe this is happening. I was living on the streets. She helped me get a place.
Stella: This was all part of the plan. Debbie and Grace waited two years, enough time for the policies to mature and pay out at maximum benefits, no matter what the manner of death. Most likely, Sam, in a week, you'd have been dead.

Stella: (charging into his office) What the hell were you thinking, Drew?! I mean, this was not cute or funny or the least bit charming. I told you, I didn't want you to send me any more gifts, and I thought I made it perfectly clear that I was not interested. And then you put this box on my truck? I called the bomb squad, Drew.
Drew: It's not from me, Stella. Look, every gift I sent to your office was with a card. You know, there was a theme going on, in case you hadn't noticed. A puzzle doesn't exactly say 'take a risk'.

Stella: (entering with a mug in her hands) I just finished my third cup of coffee. Figured you could probably use one.
Lindsay: Oh, thanks, Stella. Thought we weren't supposed to drink in the lab?
Stella: We aren't, but at some point, the human body either requires sleep or massive quantities of caffeine.
Lindsay: God bless you.

Stella: (helping Mac carry a Christmas tree) So you had to pick the biggest one, huh?
Mac: It's a Taylor family tradition. Every Christmas we visit all the tree lots looking for that one. And then the day after New Year's, when everybody puts their trees out by the curb, my dad would drive us around the neighbourhood to see if we could find a bigger one than ours.
Stella: And?
Mac: 17 Taylor Christmases, never once did we find a tree that beat us.

Stella: (outside the bank) Where's Mac?
Flack: With the body.
Stella: Oh, you gotta be kidding.
Flack: This ain't your everyday bank robbery, Stell. This guy made three demands. Unmarked police car, no press and somebody from Crime Scene.
Stella: He wanted one of us?
Flack: He swears he didn't kill the guy inside and he wants someone in there to prove he's not a murderer.
Stella: So Mac agreed to meet one of his demands?
Flack: In exchange for a hostage.
Stella: (about Gunman/Joe) Oh, this guy is smart. Now he's got a cop for insurance.

Stella: (outside the bank, about Gunman Joe) This guy's not a shooter. There's something else going on. We need more time.
Richard Jackson: Time is not what you give to a hostagetaker, Detective.
Stella: Thirty minutes. Thirty minutes and then it's your show.
Richard Jackson: All right, thirty, starting now. After that, I'm taking the first steps towards ending this thing.
