Herrmann: I'm going to make a firefighter out of you.
Dawson: That's exactly what I want.

Dawson: How was your day?
Casey: Lieutenant problems. Severide.
Dawson: How bad is it?
Casey: He's slipping away.
Dawson: You of all people know what it's like to lose someone close to you, baby. What pulled you out?

Casey: To your first day as a firefighter.
Dawson: And yet I almost got a guy killed and my Lieutenant yelled at me.

Severide: You know what I can count on? Nothing. No one. So why don't you and everyone else in this house just leave me alone. Really.

Peter, this choice that you made is commendable, but I feel compelled to tell you that other firefighters have gone down this road only to find themselves chasing ghosts.

Mills: I guess so.
Leonard: Peter. Peter. I sure am glad to know you.
