The season 14 finale of Chicago Fire will feature a surprise return from a fan-favorite character following their shocking hiatus.
The first look at the May 13 finale of the hit NBC series showed Dermot Mulroney reprising the role of Pascal. Viewers last saw Pascal in March when his position was revoked because he previously disobeyed a federal agent’s order to stand down while collecting evidence at a house fire.
Pascal was arrested, but despite the federal charges against him being dropped, his position was still in jeopardy. He ultimately confirmed to Firehouse 51 that he was told to vacate the position effective immediately. Amid the big professional change, Pascal considered retiring from firefighting but then shared that a former colleague in Phoenix offered to connect him with a firehouse in Arizona.
“He’s been on the ropes,” showrunner Andrea Newman told NBC Insider at the time. “[The arrest] puts him in a situation, it’s kind of a journey for him from the beginning, where he really wasn’t connected to 51 as closely as the chiefs obviously we’ve seen in the past, like Boden.”

Newman continued: “So he makes the ultimate sacrifice for his team, for all the teams really in this episode, and it sends him in a totally different and new direction at the end here. And he’s gonna have to figure out if he’s going to fight and claw to get back to 51, or if he’s now going to be on a new path altogether.”

Kelly Severide (Taylor Kinney) later learned that Pascal left his office — and a copy of the captain handbook — to him as a way of passing on the position of interim commanding officer. The onscreen shakeup comes after news broke that Mulroney’s Pascal would be absent from the rest of season 14.
Deadline reported in January that the character would be written off the show — for now — through a story line that required him to be off screen. Mulroney, 62, appeared on the show until Rob Morgan took over his position at Firehouse 51.

Mulroney will have a chance to return, but his future in the franchise is still unclear. The One Chicago universe is no stranger to cast shakeups. NBC’s president of program planning Jeff Bader has previously addressed the way Chicago Fire, Chicago Med and Chicago P.D. have often lost fan-favorite characters.
“Cast comes in, cast goes out,” Bader told TVLine in July 2024. “It’s interesting, because every year there are cast changes, and every year someone asks the same question about what’s going on within the One Chicago universe. But [those shows] just keep going on.”
Bader noted that each of the Chicago shows have continued to find success, adding, “We’re thrilled with how the Chicagos do on Wednesday. We have no plans on changing anything on that night.”
Chicago Fire airs on NBC Wednesdays at 9 p.m. ET.
