Protection.
There were bloodstains on the door, broken glass in the street. Kelly is on the floor and Matt is trying to remove small pieces of glass in his legs.
What the hell were you thinking? Another fight?
-No Case, those gangsters who hurt you the other day, I saw them and I had to do something to them.
- Are you sure about that? You can't go to the street and hit someone weird, Severide that was wrong.
- I'm 100% sure, I just talked to someone, I kicked them and while doing it they threw me to the ground and they hit me with a bottle.
- I understand and appreciate what you did, but it was not the way.
- "I'll keep kicking their asses every time they want to hit my lieutenant."
-I can defend myself.
-Not when I'm here to protect you
