A closer look at “Dermot Mulroney's Chief Pascal Exits 'Chicago Fire' in Season 15 Premiere”, exactly as the source publishes it. NBC's Chicago Fire opened its fifteenth season with a major cast departure. Dermot Mulroney, who joined the series in Season 14 as Chief Dom Pascal, made his final appearance as a series regular in the premiere. The episode, written by showrunner Victor Teran and directed by Reza Tabrizi, resolved the cliffhanger from last season's finale, which left several members of Firehouse 51 in life-threatening situations.
While most of the team survived, Pascal's storyline concluded with an emotional farewell, marking the end of Mulroney's tenure on the long-running drama. The exit comes as the series continues to evolve under Teran's leadership, with the premiere setting up new dynamics for the crew. Fans will be watching closely to see how the firehouse adjusts to another leadership change, and whether Pascal's departure opens the door for a familiar face to return.
