Cuyler: I will stop fooling around if you will grant me one date, with flowers and candles, and Sheakspearian sonnets.
Colvin: You know I can't do that
Cuyler: I know you feel like you have to be your best, but you can't let the job be your whole life Teresa.

Wysocki: What was he into Karen?
Karen: I can't tell you
Wysocki: Tell me what? That he was dirty? I already know.
Karen: He said it would break your heart

One thing I have learned about fighting crime in Chicago, it's a marathon not a sprint, you better be ready to go the distance.

Colvin

Chris [Liam]: I got into this to get Gibbons. What did I get shot for? If she can get Gibbons, give her whatever she wants.
Colvin: There were times when I wondered if you were up for this job [smiles].

"Pops" Wysocki: You need to stop them Jarek
Wysocki: It's not them pop, its me.
"Pops" Wysocki: You needed to talk to me first!
Wysocki: If I had done that I wouldn't have been able to do it.

Gibbons: Your days in Chicago are numbered Teresa.
Colvin: Whatever the number, it's more than yours.

Teresa: Your partner has better instincts than you think.
Jarek: Too bad he's a Cubs fan.

I'm really good.

Caleb

Jareck: There's a lot of history in that sausage.
Caleb: I can taste it.

Isaac: When people ask me how I escaped gang life, I always tell them the same thing: I didn't. I joined the baddest gang in town.

I'm a lot of things, but I ain't gonna be no hypocrite.

Jareck

Caleb: If we can't even trust other cops to have our backs, this job gets dangerous.
Jarek: Yes it does.
