In Season 14, Episode 6, “Broken Things,” viewers welcomed back actor Dermot Mulroney, who plays Battalion Chief Dominick “Dom” Pascal.

Mulroney’s character had been noticeably absent for two episodes (Episodes 4 and 5) of the season, with the in-universe explanation being that he was assisting at other firehouses following budget-related layoffs of six battalion chiefs in the CFD. His return not only resolved his temporary disappearance but also signaled a significant emotional and professional shift for the character, kicking off a new, complex storyline.

But who is the veteran actor behind the disciplined yet complex Chief, and what makes his return so crucial to the future of Firehouse 51? Dermot Mulroney is a seasoned Hollywood professional whose diverse career, spanning romantic comedies to action thrillers, lends unique gravitas to the One Chicago universe.


👨‍🚒 Dermot Mulroney as Chief Dom Pascal: A Study in Contrast

Dermot Mulroney joined Chicago Fire in Season 13, taking over Firehouse 51 after the promotion of the beloved Chief Wallace Boden (Eamonn Walker) to Deputy Commissioner. Mulroney’s character, Chief Dom Pascal, immediately set himself apart, providing a stark contrast to Boden’s fatherly, intuitive leadership style.

Pascal’s Defining Characteristics

  • Background: Pascal had led a firehouse in Miami for 10 years before returning to Chicago to lead Battalion 25, bringing with him a decade of experience as a chief.
  • Leadership Style: He is known for being structured, disciplined, and professional. He implemented stricter protocols, such as technology restrictions during meals and call debriefings, which initially caused friction with the 51 crew, notably Lieutenant Stella Kidd.
  • Initial Tensions: Pascal’s initial tenure was marked by being “hard to read,” leading to early tensions. Showrunner Andrea Newman noted that a key moment defining his acceptance by the team was at his wife Monica’s funeral, where Mouch told him, “That’s why we’re here, chief,” solidifying Pascal’s understanding that he was part of the 51 family.
  • Personal Turmoil: Pascal’s life was shattered by the death of his wife, Monica, in a car accident. This tragedy tested his leadership, leading him to take risks in emergencies and question his safety, reflecting the emotional and professional turmoil the character continues to face. Furthermore, his time in Miami hints at past secrets that have impacted his life in Chicago, linking him to an attempted murder and arson case after Monica’s death.

🔙 The Significance of Pascal’s Return in Season 14, Episode 6

Chief Pascal’s return in Season 14, Episode 6 was strategically timed to shift the narrative focus and introduce a key mentorship dynamic.

The Unexpected Absence

Pascal was “MIA” (Missing In Action) for Episodes 4 and 5 of Season 14. This in-universe absence was explained as him assisting at other firehouses due to the firing of six battalion chiefs across the CFD in a budget cut measure. The brief break fueled fan speculation, but his return confirmed his commitment to the show.

The Mentorship Dynamic

Upon his return in “Broken Things,” Pascal immediately focused on strengthening his bond with Lieutenant Kelly Severide.

  • Passing the Torch: Having previously trusted Severide to look after 51 during his absence, Pascal now took Severide further “under his wing.”
  • Shadowing Role: The episode saw Severide shadowing Pascal for the day, with the pair working together to review plans. Their collaboration involved meeting with Mayor Benning’s Chief of Staff, Annette Davis, suggesting their work relates to high-level CFD matters that could impact the entire department.
  • Emotional Compassion: His return showed a more compassionate side, with Pascal mentoring his fellow firefighters through difficult situations, balancing his demanding leadership style with a necessary emotional well-being.

The mentor/mentee dynamic with Severide is a crucial development, evolving from initial tension to a unique partnership that adds depth and complexity to the Firehouse 51 command structure.
