Danny Borelli V. Chief Wallace Boden

In "Chicago Fire" Season 4 episode 22, rookie firefighter Jimmy lost his brother Danny (Andy Ahrens) while saving lives. However, Jimmy is blaming Chief Wallace Boden (Eamonn Walker) for his brother's death.

Chief Boden gave permission to Danny to stay longer in the collapsing building when he heard someone still inside the building. This led to the demise of Danny in "Chicago Fire" Season 4 episode 22.

"As a chief, you do a lot of telling people what to do without actually doing very much yourself," Jimmy tells Boden in an explosive "Chicago Fire" Season 4 finale clip from the Hollywood Reporter.
