Steve: I'm saying this case is a mess. You shot an African American teenager, who from the reports I've seen, never actually fired his weapon.
Lindsay: Are you kidding me? Have you ever looked down the barrel of an automatic weapon? No? Good.

Lindsay: So it's your birthday tomorrow.
Halstead: You remembered.
Lindsay: How could I forget? Pops up in my Google calendar.

Hank, you go pulling a thread, there's no telling what all unravels. Quit digging into this, or, what was the line you used to say all the time? Oh yeah, "we're going for a ride."

Lindsay

Valentine: Lucky? I've been rotting in here like meat for 17 years!

You might not believe it but I used to go undercover as a street walker 20 years ago. [Burgess and Lindsay give her a look] Okay 25 years ago.

Burgess: It's the perfect fit. I know the case, I work well with Lindsay, and I'm the right gender.

Burgess: Like you were too close to Justin?

Lindsay: Harry Klinsman? Chicago PD. We need to talk.
Harry: About what?
Lindsay: Manslut, and what you were doing last night.

Voight: Do you drive a black Audi Q7?
Goldwin: Yeah, you a car guy?
Voight: Only when they're involved in a crime.

Burgess: Sarg?
Voight: Yeah?
Burgess: Thank you for taking this on.

My mom never even told me who my dad is. It was always just me and her, and she was a terrible parent. She failed me every time. And I took it, because I had no choice. She was all I knew, all I had. So I stand there in front of her, and I take it on the chin. And every single hit has hurt. So I look at you and I look at what you're going through, and I think to myself there's gotta be a time where we stop standing up for more.
