That smug face you're wearin', It's gonna come off.

Voight

How does a gun buy-back program turn into a homicide investigation?

Platt

Maybe you couldn't think straight with the music being so loud. Sit down.

Antonio

Platt: Congratulations. You're on gun buy-back duty at the grocery store over on Ash.
Sean: What does that entail?
Platt: People turn in guns, you give them a grocery gift card. No questions asked. And bring your galoshes. You're going to get soaked in that parking lot.

Lindsay: Anyway, I just want to say thanks for taking me in. You're my family.
Voight: You're about the best thing that every happened to me. I mean that.

Ruzek: I want you so bad right now.
Burgess: My place. One hour.
Ruzek: Hell yes!
Burgess: You have been a bad boy.
Ruzek: Don't talk to me like that right now... come here.

This is crazy! The guy can take a shot at any time.

Lindsay

First of all, it's detective. Second of all, let's me and you not get off on the wrong foot.

Halstead

Oh the investigation can begin everyone! Nadia's here. What'd you do, take a bus?

Platt

Halstead: Come on. Can I crash with you?
Lindsay: Are you going to try to play scrabble with me, too?

Enrietto: Hey Hank, wanna play some pinochle?
Voight: Nah, nah. I just sent a teenager away for murder and I got a friend layin' in the morgue. I'm just gonna sit here and drink this beer.

Lindsay: You know what I do remember about the 4th of July?
Bunny: What?
Lindsay: That time you ODed on the kitchen floor.
Bunny: Oh.
Lindsay: I didn't think a 70 pound girl could lift a grown woman like that. I knew I couldn't call 911 for help because I knew CPS would take me from you. Then I dragged you into the bathtub. I kept filling it with ice cubes, just sittin' there hopin' you didn't die.
Bunny: Do we really have to bring up all this negative stuff?
Lindsay: I was nine. And do you know what you said to me when you woke up? [Bunny shakes her head] Get my cigarettes.
Bunny: I made amends with you, Erin.
Lindsay: Oh I know you did. And I know you don't like talkin' about it. But if you want to get back into my life, sometimes I'm gonna have to. Your call.
