"Chicago Fire" is all new Tuesday night, when Severide (Taylor Kinney) will express his anger towards the new boss for treating him like a candidate.

"Their rivalry has been growing but on Tuesday, it will put people's lives in risk," reads the promo for Episode 6 of Season 4, posted to the show's Facebook.

In the clip of the coming episode, Patterson (Brian White) bluntly tells Severide, "I'm the one calling the shots."

When a man is knocked unconscious and begins bleeding from the head, the tension between Severide and Patterson even prevents them from agreeing on the proper response.

Even though the bleeding man is in great danger, when Severide suggests a way to fix the situation, Patterson completely shuts him down.

"We need to pull him out of the car and just load and go," Severide says in the trailer.

"Negative. I didn't ask for your opinion," Patterson responds.

"Severide is upset when he's treated like a candidate by Patterson," the show's description reads on TVGuide.

Will Severide stand up to Patterson and finally tell him how he really feels? How will Patterson react? The boss is shooting for the top position and is willing to do anything to get there. He may not even care what Severide has to say.

Meanwhile, "Boden's (Eamonn Walker) new neighbor asks him for a favor that could have serious repercussions and Cruz (Joe Minoso) is visited by a gangbanger who knows his brother," the description continues.

What will his neighbor ask him to do? Will he take the risk? And why is a gangbanger visiting Cruz? Could his brother be in danger?

Meanwhile, the team responds to a call that involves an 18-wheeler. Then someone thanks them for their hard work by giving them free tickets to see Rush.

Will Severide and Patterson finally work together effectively?

Tune into NBC on Tuesday night at 10 p.m. to catch the new episode of "Chicago Fire" to find out.

Place your bets… it’s going down.
