When Does Dawson Leave Chicago Fire? – Gabriela “Gabby” Dawson (played by Monica Raymund) leaves Chicago Fire at the end of Season 6 in the episode “The Grand Gesture” (Season 6, Episode 23, aired May 10, 2018). She accepts a job leading relief efforts in Puerto Rico and departs Firehouse 51. She returns for emotional guest appearances in Season 7 and Season 8 before the character’s story largely concludes.
The Season 6 Finale: “The Grand Gesture” – Dawson’s Departure Episode
In the Season 6 finale, Chief Karl Hatcher offers Dawson a significant opportunity to lead a rescue and medical aid unit in Puerto Rico, which is still recovering from devastating hurricanes.
After a painful argument with her husband, Captain Matt Casey, about their future and attempts to start a family (complicated by Dawson’s health risks and past trauma with their foster son Louie), Dawson decides to accept the position. The episode ends with her leaving Chicago for this new chapter.
The departure feels abrupt to many characters and viewers because everyone assumes she will eventually return.

Why Did Gabby Dawson Leave Chicago Fire in the Story?
In-universe, Dawson’s exit stems from a combination of professional opportunity and personal crossroads. The Puerto Rico role allows her to lead a meaningful humanitarian effort using her paramedic and firefighter skills.
Her marriage to Casey reaches a breaking point over differing views on parenthood and life priorities. Casey wants to stay rooted in Chicago and consider adoption; Dawson feels called to the urgent work in Puerto Rico. She ultimately chooses the new path, leading to their separation.
Monica Raymund Announces Her Exit from Chicago Fire
In real life, Monica Raymund confirmed in May 2018 that she would not return for Season 7 after six seasons as a series regular. Her six-year contract was ending, and she wanted to explore new roles and stories.
She told the Chicago Tribune: “I knew that my six-year contract was coming to an end and I felt like I was hungry to explore a different role, a different story. I wanted to explore a different world… I had been in Chicago for five years and just personally where I was in my life, I was ready to create my home and kind of plant some roots in Los Angeles.”
Showrunner Derek Haas was initially caught off-guard, assuming it might be contract negotiation. Raymund’s decision required the writers to adjust long-term plans significantly.

What Happened to Gabby Dawson After Leaving Firehouse 51?
Dawson builds a new life in Puerto Rico, leading rescue and medical aid efforts for communities in need. She and Casey eventually divorce. The character’s story emphasizes her passion for helping others and her willingness to follow her calling, even when it means leaving the people and city she loves.
How Dawson’s Exit Impacted Chicago Fire and Firehouse 51?
The show handled the departure thoughtfully by giving Dawson (and Raymund) proper emotional send-offs across multiple episodes rather than a rushed exit.
Emily Foster (later replaced by other paramedics) joined Ambulance 61 as Dawson’s replacement. The loss of a core original character shifted dynamics at Firehouse 51 and opened storylines for Casey’s personal growth and new relationships. Fans still frequently discuss “Dawsey” and hope for future cameos.
