Dermot Mulroney Exits 'Chicago Fire' Ahead of Season 15 Premiere
Dermot Mulroney is leaving 'Chicago Fire' in Season 15. Find out when his final episodes air and how to track the NBC drama’s upcoming episodes.
You’re scrolling through your watchlist, coffee in hand, when you remember—wait, wasn’t Dermot Mulroney just starting to settle into Firehouse 51? You’re not imagining things. According to Variety, Mulroney is indeed exiting Chicago Fire early in Season 15, wrapping up his arc as Chief Dom Pascal just as the new season kicks off. For fans who’ve followed his journey since Season 13, it’s a bittersweet twist—but one that opens the door for fresh dynamics at the firehouse.
Dermot Mulroney Confirmed Exit from ‘Chicago Fire’
Variety confirmed this week that Dermot Mulroney will depart Chicago Fire early in Season 15. The actor joined the long-running NBC drama in Season 13 as Chief Dom Pascal—a steady, sometimes stern presence brought in during a period of upheaval for Firehouse 51. His exit comes after a relatively short but impactful tenure, with his final scenes expected to air in the season’s opening episodes. While the show hasn’t revealed exact plot details, sources indicate his departure is written into the narrative rather than abrupt. This isn’t a sudden recast or behind-the-scenes fallout—it’s a planned conclusion to his character’s chapter.
Timeline of His Character’s Arc on the Show
Dom Pascal first appeared in Season 13 as part of a leadership shake-up following the events of the Season 12 finale. Tasked with restoring order and accountability, Pascal initially clashed with longtime crew members—especially Matthew Casey and Kelly Severide—who viewed him as an outsider imposing bureaucracy on their tight-knit unit. But over time, Pascal proved his commitment to the team’s safety and integrity, earning cautious respect. Key moments included his handling of the Dawson custody crisis and his quiet support during Mouch’s recovery from injury. By the Season 14 finale—recapped here—Pascal had evolved from an authority figure into a reluctant ally, making his exit feel like the end of a bridge between old and new eras at 51.
What This Means for Season 15’s Storylines
With Pascal gone, Firehouse 51 faces another leadership vacuum—and likely another round of internal tension. Who steps up? Will Boden return to a more active role? Or could we see someone like Kidd or even Cruz take on greater command responsibilities? Pascal’s absence also removes a key voice of institutional caution, which may allow the crew to operate with more autonomy—but also more risk. Given Chicago Fire’s pattern of using cast changes to fuel emotional arcs, expect his departure to ripple through multiple storylines, possibly reigniting old conflicts or accelerating character growth for younger firefighters. It’s classic One Chicago: loss creates space for reinvention.
Season 15 Premiere Date and What to Expect
Mark your calendar: Chicago Fire Season 15 premieres October 7 at 9 p.m. ET on NBC. The new season promises high stakes right out of the gate—not just with Pascal’s exit, but with ongoing fallout from last season’s near-fatal warehouse fire and unresolved personal threads (looking at you, Brett and Foster). Early promotional materials hint at deeper exploration of mental health, workplace trauma, and the cost of heroism—themes the franchise has leaned into more boldly in recent years. And yes, crossovers with Chicago PD and Chicago Med are all but guaranteed, especially as the One Chicago universe continues to intertwine its emergency responders.
How to Keep Up With ‘Chicago Fire’ Episodes
Let’s be real: it’s easy to fall behind when your favorite procedural drops 20+ episodes a season. One week you’re caught up, the next you’re three episodes deep with no memory of who got promoted or why that paramedic looked so familiar. That’s where tracking comes in. Apps like ScreenAtlas let you mark episodes as watched, set reminders for new air dates, and even revisit past seasons without digging through streaming menus. Since Chicago Fire Season 15 starts October 7, now’s the perfect time to tidy up your watchlist—maybe even rewatch Pascal’s debut arc before his farewell. ScreenAtlas is free on iOS today and built specifically for fans who treat their TV schedule like a second job (we see you).
