Chicago Fire Season 8 Quotes

The order was mine. In a fire scene, in all the chaos and unpredictability, a firefighter can only relay back to his incident commander the information he has at the time, but it is up to the chief to make a decision where or when to send the additional resources … It was I, not Captain Casey, not anyone else, but I who ordered them into the fire scene. So if you are looking to blame someone, if you are looking for a human scapegoat, blame me.

Boden

Cruz: I know you’re going up to a better place and I know when you get there, they’re going to welcome you with open arms. Maybe, you could save us a place to live up there together, you know. I’ll be there someday. I love you brother. I love you, and I’m going to miss you.
Otis: Brother, I will be with you always.
