Core Event – Mulroney’s Exit Confirmed
Dermot Mulroney, who joined NBC’s procedural drama Chicago Fire in season 13 (2024) as Battalion Chief Dom Pascal, will appear in a single episode of the upcoming season 15 before the character is written off. The actor disclosed at the Flashback Weekend Chicago Horror Convention that his final filming day is scheduled for a Tuesday, after which his storyline concludes. Season 15 is slated to premiere on October 7 at 9 p.m. ET on NBC.
Background & Context – Recent Cast Turnover
“Chicago Fire,” which debuted on October 10, 2012, has undergone several high-profile departures. Series lead Jesse Spencer left in 2021, followed by longtime cast member Eamonn Walker the same year. Longtime firefighter Joe Miñoso, who has portrayed Joe Cruz since the pilot, is also exiting early in season 15. In contrast, series leads Taylor Kinney (Captain Kelly Severide) and Miranda Rae Mayo (Lieutenant Stella Kidd) are confirmed to return, and “BMF” star Da’Vinchi has been added as series regular Marcus Burke. Mulroney’s exit therefore represents the latest in a series of cast changes as the show prepares for its fifteenth season.
