An intense battle between Boden (Eamonn Walker) and Jimmy (Steven R. McQueen) will be front and center in "Chicago Fire" season 5, and it looks like it won't end until one of them is eliminated.

Dubbing the clash as "the main battle," executive producer Matt Olmstead teased to TV Line that "one of them isn't going to be around [after the battle].

That being said, "Chicago Fire" season 5 will see someone out of Firehouse 51 soon. There's no way of knowing who it will be, but it should be one epic showdown.

The clash will spring from the demise of Danny, who sacrificed his life in order to save helpless people from a building that's about to crush them. Although he died a heroic death, Jimmy believes that Boden's decision practically killed his brother.

"Jimmy becomes convinced that Boden made the wrong call on letting his brother stay inside the building and starts to look at Boden as responsible for that," Olmstead told The Hollywood Reporter.

Boden feels that he did make the right decision and tries to make Jimmy understand in "Chicago Fire" season 5 that "the game you play about when to get in and when to get out is no perfect science and sometimes people play real costs for it."

While this conflict is only between these two men, Firehouse 51 will be shaken to its core and the rest of the members will be inevitably roped in. Some will give Jimmy advice and understand him in this trying time, but Jimmy is of one mind in "Chicago Fire" season 5.

"He thinks he's looking at a guy who made a mistake, won't admit it, and his brother paid the high price for it," Olmstead explained.

"Chicago Fire" season 5 premieres this fall on NBC.
