Lindsay: 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.

Voight: Trouble at home?
Halstead: No, we're just working some stuff out.
Voight: I heard all that before. I'm done with that now. I warned both of you. So clear it up, get back to doing your job, or you're gone, you understand?

Ruzek: It's Adam. Remember I last saw you at your husband's birthday?
Nicole: Oh I remember you. I had your engagement photo pinned to my fridge for eight months.

Voight: Hey you're gonna miss your bus.
Kid: Who got popped?
Voight: A kid who missed his bus.
