Dermot Mulroney to Depart Chicago Fire as Chief Pascal Exits in Season 15

Mulroney noted at Flash Weekend Chicago Horror Convention that fans often request Chief Pascal autographs for their dads rather than autographs for his film work, underscoring the character's impact beyond the show. He said, "They'd rather have an autograph on 'Scream VI,' but [they ask for] Chief Pascal for their dad."
Mulroney revealed he temporarily stepped away from Chicago Fire during the latter half of Season 14 and returned for the season finale, with his exit officially written to occur early in Season 15.
The departure of Mulroney comes amid a broader cast shakeup at Firehouse 51, with other long-standing cast members such as Daniel Kyri and Jake Lockett having left in recent years as production moves toward Season 15.
Season 15 is set to premiere on October 7 at 9 p.m. ET, continuing what producers describe as a thrilling and meaningful run for the series.
Mulroney joined Chicago Fire in Season 13 as Chief Dom Pascal following Eamonn Walker’s departure, bringing a new leadership dynamic to Firehouse 51.
Dermot Mulroney is leaving NBC's Chicago Fire after two seasons as Chief Dom Pascal, with his character set to be written off early in Season 15. Variety reports that Mulroney confirmed the news at the Flash Weekend Chicago Horror Convention, saying, "We gave it our all for two seasons."
Season 15 premieres October 7 at 9 p.m. ET. Mulroney joined the show in Season 13, stepping in after Eamonn Walker's departure to lead Firehouse 51 as its new chief.
Mulroney told convention attendees he has just one episode left before his exit airs. Variety reports he called the experience bittersweet. "Sad to see it go," he said. He praised the cast and the writing staff for delivering emotionally tough scenes throughout his run.
MEAWW reports that Mulroney stepped away from the show during the second half of Season 14, then returned for the season finale. His exit is written into the early episodes of Season 15. He described the show's portrayal of first responders and their families as meaningful and impactful.
Mulroney has a long film career, including roles in major Hollywood titles. But at the convention, he noticed something surprising about fan requests. Soap Central reports he said fans ask for Chief Pascal autographs for their fathers rather than autographs tied to his movie work. He joked, "They'd rather have an autograph on 'Scream VI,' but [they ask for] Chief Pascal for their dad."
The anecdote shows how deeply the character connected with viewers, especially those who admire first responders. Mulroney said he loved every minute of playing the role. He called the Firehouse 51 community meaningful to him personally.
Mulroney's exit is part of a larger shakeup at Chicago Fire. Coming Soon reports that other cast members, including Daniel Kyri and Jake Lockett, left the show in recent seasons. Original cast member Joe Miñoso is also departing as production moves into Season 15.
The show has been running for over a decade, and producers say Season 15 will continue what they describe as a thrilling and meaningful run. The series remains one of NBC's long-standing drama hits, drawing viewers who connect with stories about firefighters and their families.
Head Topics reports that Season 15 kicks off October 7 at 9 p.m. ET. The new season will air Mulroney's final episode early in the run, closing out Chief Pascal's chapter at Firehouse 51. It is not yet clear who will step into a leadership role after his departure.
Mulroney joined Chicago Fire in Season 13, bringing a new dynamic to the show after Walker's exit. His two-season tenure added a fresh layer to the firehouse's leadership story. Fans and the cast will now watch to see how the show fills the gap he leaves behind.
