Dermot Mulroney, who recently joined Chicago Fire as Battalion Chief Dom Pascal in the beginning of Season 14, will step away from the series for a temporary hiatus later in the season.
The break is part of the show’s planned storyline rather than an abrupt exit. Mulroney is expected to appear in several upcoming episodes, including the One Chicago crossover event, before his character is written out for a portion of the season. A return later in the season has not been ruled out.
Mulroney’s arrival introduced a new leadership dynamic at Firehouse 51 following the transition of longtime character Chief Wallace Boden. His portrayal of Pascal has unfolded gradually, revealing a more reserved and measured presence that has added tension and complexity within the house.
During Pascal’s absence, the series will introduce a new battalion chief to oversee Firehouse 51. Actor Rob Morgan has been cast in a recurring role as Battalion Chief Hopkins, a seasoned CFD leader who will step into the command position beginning mid-season and remain in place through the later episodes of the arc.
The leadership shift continues a season-long theme of transition for the series, while allowing space for new character dynamics to develop inside the house.
Mulroney’s hiatus does not signal a permanent departure, but it does mark another evolution for a long-running series that continues to adjust its ensemble while maintaining the identity that has defined Chicago Fire for more than a decade.
