Overview
- Mulroney told fans at Flashback Weekend that he finished filming one Season 15 episode on July 28 and that the show will write his Chief Dom Pascal out early in the season.
- Reporting from multiple outlets says original cast member Joe Miñoso will also be written off in the early episodes of Season 15.
- Mulroney described his time on the series as rewarding but emotionally heavy, praising cast and crew and calling his departure “sad” and “bitter.”
- Production changes include the promotion of Victor Teran to showrunner and a Season 15 premiere set for Oct. 7, and NBC has declined to publicly confirm the reported exits or on‑screen outcomes.
- The departures will require narrative closure for Firehouse 51 and are likely to shape early-season storylines, and viewers should watch for official network statements and how the changes affect the One Chicago franchise.
