A key cast member has confirmed their exit from the long-running NBC drama Chicago Fire. The news comes just weeks before production gears up for the show’s fifteenth season, which is another significant shift at Firehouse 51.

Dermot Mulroney is ‘sad’ to leave Chief Pascal and Chicago Fire

Dermot Mulroney will exit Chicago Fire after two seasons, with his character’s storyline set to end early in the upcoming Season 15. The actor confirmed his leaving while speaking at Flashback Weekend Chicago Horror Convention, giving his first public reaction to the news.

“Loved every minute of it. Became friends with this incredible crew of people,” Mulroney told the audience. He praised the “incredible cast” he worked alongside and noted that the writers consistently gave him “incredibly challenging scenes” throughout his tenure on the series.

Furthermore, Mulroney revealed he has just one episode remaining, which will air as part of Season 15. “They write the character off,” he explained. “We gave it our all for two seasons. They wrote an incredible storyline that put me as an actor on a high challenge. I loved every minute of it. Sad to see it go” (via Deadline).

The actor joined the Wolft Entertainment and Universal Television series in Season 13, stepping into Firehouse 51 as Chief Dom Pascal following Eamonn Walker’s departure from the show. His character brought a new dynamic to the firehouse leadership, navigating complex emergencies and internal tensions. Mulroney temporarily stepped away during the latter half of Season 14, with his character placed on hiatus, before returning for the season finale.

During the same event, Dermot Mulroney reflected on Chicago Fire’s broader significance, particularly for first responders and their families. “That’s how meaningful that is, which makes it that much more—I won’t say bittersweet; it’s better to have to leave that,” he said, acknowledging the deep connection the audience holds for the series.

Now, specific plot details surrounding Chief Pascal’s exit remain under wraps, though Mulroney’s comments suggest a substantial send-off episode.
