All the “Chicago Fire” Actors Who Have Said Goodbye to Firehouse 51 (Including Dermot Mulroney’s Season 15 Send-Off)

**Chicago Fire Enters Season 15 with Key Cast Changes**

The long-running series Chicago Fire kicked off its 15th season on 7 October, but fans of the show will notice some significant changes in the cast. As the drama unfolds in the fictional firehouse, Firehouse 51, the departure of several key characters signifies a new chapter for the beloved series.

One notable exit this season is that of Dermot Mulroney, who played Battalion Chief Dom Pascal since 2024. Mulroney’s final appearance came in the season opener, marking a swift end to his tenure on the show. Speaking at a recent panel, he expressed gratitude for the opportunity, acknowledging that the storylines he worked on pushed him as an actor but regretting that he had only one episode left before his character departed. “We gave it our all for two seasons,” he said, reflecting on his time on the show.

Behind the scenes, Chicago Fire has seen numerous cast members come and go since its debut in 2012. The dynamics of Firehouse 51 have shifted with each departure. Eamonn Walker, who was an original cast member portraying Chief Wallace Boden, stepped away as a regular at the end of season 12. Other familiar faces have also exited over the years. Jesse Spencer, known for playing Matt Casey, left the show in season 10 but returned briefly for important storylines.

The show is not just losing Mulroney. Joe Mińoso, who has portrayed Joe Cruz, is set to exit later in the current season, leaving fans to wonder how the storylines will evolve as the core team continues to change. This wave of departures highlights the challenges of maintaining a long-running series, where fresh talent and storylines are often necessary to keep viewers engaged.

Michael Bradway, who portrayed Jack Damon, made his own exit after season 13. He reminisced about his time on Chicago Fire, calling it his “boot camp into television.” His departure appears to be a natural progression for an actor who has since taken on new roles, including a recent series adapted from a bestselling novel.

Similarly, Jake Lockett, known for his portrayal of Sam Carver, also left at the conclusion of season 13. He marked his exit on social media expressing his pride in the role he played. Like others, Lockett’s departure was believed to be part of a budgetary tighten, indicating that the series is navigating financial constraints while trying to retain beloved characters.

Daniel Kyri, who played Darren Ritter, also exited the show after season 13, following a promotion from a recurring character to a series regular. His departure has been confirmed through social media, where he expressed heartfelt gratitude to fans and colleagues alike.

Of course, not every departure has been final. Eamonn Walker made a guest appearance the season after his exit, indicating that sometimes, the door remains open for returning characters. He spoke warmly about reuniting with the cast, highlighting the bonds that form through collaboration, suggesting that time apart does not diminish those connections.

As Chicago Fire moves forward, the legacy of its characters continues to be felt. The show has experienced significant growth, evolving its narrative through the introduction and exit of various characters, much like the real-life challenges faced by fire crews. As fans settle in for what’s to come this season, one thing remains certain: Firehouse 51 has seen its fair share of both heroic feats and heartfelt goodbyes, making it a cornerstone of ensemble drama on television.

Chicago Fire continues to demonstrate resilience and adaptability, traits essential both for the series and the firefighters it portrays. Whether through new storylines or revisiting familiar faces, the show aims to maintain its reputation for thrilling drama that resonates with audiences, even as it embraces change.
