What Dermot Mulroney’s Departure From ‘Chicago Fire’ Means for Firehouse 51

News of Dermot Mulroney leaving ‘Chicago Fire’ arrived on July 31, when reports said the actor would depart the NBC drama early in its upcoming 15th season. His exit concludes his role as Chief Dom Pascal. The announcement landed just days after another cast departure, which gave the news added weight among longtime viewers.

The question of why he is going has a more modest answer than the headlines suggested. NBC declined to confirm the report when reached by USA Today. What Mulroney has said publicly points to a storyline decision, and the details are worth laying out carefully.

The Dermot Mulroney Exit and What Has Been Confirmed

Deadline first reported the news, and TVLine later confirmed that Pascal’s storyline will be wrapped up early in the season. A representative for Mulroney did not immediately respond to USA Today’s request for comment. No formal statement from the network or the actor has explained the decision in detail.

At Flashback Weekend in Chicago, Mulroney addressed it himself. He told attendees that he has one episode this season and that the producers “write the character off.” That framing suggests the departure is a creative choice built into the story rather than a personal announcement that he was walking away.

Some speculation appeared before the news became official. One outlet noted that production on ‘The Hunting Wives’ Season 2 was expected to begin this fall, and it raised questions about his availability. Mulroney also confirmed in May that he is expected to appear in a sequel to ‘The Family Stone.’ Neither project has been publicly tied to the exit by Mulroney or the network in the reporting available.

Chief Dom Pascal’s Road to a Final Episode

Mulroney came aboard in Season 13 as the station’s next chief. He followed the exit of Eamonn Walker’s Wallace Boden after 12 seasons. Pascal’s highly disciplined approach rubbed some firefighters the wrong way at first, but he eventually became a valued part of the Firehouse 51 team.

His storyline began to unravel in Season 14. Mulroney went on hiatus in the second half of the season. During the March crossover with ‘Chicago Med’ and ‘Chicago P.D.’, Pascal went against FBI orders to search an apartment for a hard drive and then lost his job with the fire department. A former colleague in Phoenix had been trying to recruit him for months.

Pascal did not stay gone for good. He returned in the Season 14 finale after the department’s leadership brought him back to help sway Kelly Severide’s decision, and he rode along with Firehouse 51 to the fire call behind the cliffhanger. That brief return now looks like the setup for his final farewell.

The Season 15 Premiere and Pascal’s Last Appearance

The Season 15 premiere, titled “New Blood,” was scheduled for Wednesday, October 7, on NBC. It is Mulroney’s last episode as Pascal, and NBC has released photos showing him at the scene of the fire. The premiere is also set to resolve the warehouse fire cliffhanger and address the departures of both Pascal and Joe Miñoso.

Mulroney has been open about how the filming process went. He revealed he would return for one episode, which he finished shooting on Tuesday, July 28. Cast member Brandon Larracuente told <a href=”https://www.tvinsider.com/1294045/chicago-fire-exits-joe-minoso-dermot-mulroney-pascal-cruz-details/”>TV Insider</a> that Pascal’s exit is “contingent on what happens in the cliffhanger” from the previous finale.

The actor was candid about the emotional side of leaving. He said it was bitter to depart a show whose fans include first responders and their families, many of whom approach him as Chief Pascal. He also recalled the Season 13 arc in which Pascal’s wife was killed in a car accident, and he called it demanding material for an actor.

Chicago Fire Cast Changes Beyond Mulroney

Mulroney is not the only face leaving the firehouse. Original cast member Joe Miñoso, who has played firefighter Joe Cruz since Season 1, is also exiting early in Season 15 and will appear in a few episodes to wrap up his arc. With his exit, the remaining actors on the show since Season 1 include Taylor Kinney.

The production side is shifting as well. Co-executive producer Victor Teran is taking over showrunning duties from Andrea Newman, who ran the previous three seasons. Deadline noted that Kinney and longtime star Miranda Rae Mayo are both set to return after renegotiating their deals.

The story itself leaves a clear opening. The chief’s office at Firehouse 51 will be available for Severide, who was promoted to captain and is deciding between the fire department and the Office of Fire Investigation. The season will also introduce several new probationary firefighters. With a former chief gone and a new generation arriving, Pascal’s exit may be remembered less as a loss than as a passing of the badge, so did the writers send off a man who lost his wife and his job with the ending he earned at Firehouse 51?
