Dermot Mulroney will leave the NBC drama "Chicago Fire" early in its 15th season [1].
Mulroney's departure marks a significant shift in the show's leadership hierarchy as the series prepares for its latest chapter. The exit of a high-ranking character like Chief Dom Pascal often signals new narrative directions or internal conflicts within the fictional firehouse.
Mulroney has appeared in the series for two seasons [2]. His character's storyline is expected to wrap up shortly after the season premieres, which is slated for late 2026 [3].
While some reports suggest a specific reason for the exit, no official cause has been disclosed by the production or the actor [4]. "It’s bitter to have to leave," Mulroney said [4].
He further clarified that the decision was tied to the narrative arc of the show. "I’m sad to go, but it’s the way the story is written," Mulroney said [5].
Mulroney is not the only cast member departing the series this year. At least two other main cast members are also expected to exit during Season 15 [6]. The show, produced in Chicago, Illinois, continues to rotate its ensemble cast to maintain dramatic tension across its long run [3].
“"It’s bitter to have to leave."”
The departure of Dermot Mulroney, alongside at least two other primary cast members, suggests a substantial creative overhaul for 'Chicago Fire' as it enters its 15th season. By removing established leadership figures like Chief Dom Pascal, NBC is likely clearing the way for new character dynamics and plotlines to prevent narrative stagnation in a long-running procedural.
