1. Matthew Casey – The Quiet Leadership Exit

One of the most emotional departures in Chicago Fire history came when Matthew Casey left Firehouse 51 to start a new chapter in Oregon.

After years as a core leader of the team, Casey chose to relocate to care for the children of a fallen friend and pursue a more settled life away from Chicago. His exit wasn’t explosive—but it was deeply emotional, marking the end of an era for the firehouse.

Although he has made brief returns since leaving, Casey’s absence from the daily life of Firehouse 51 left fans wondering if the show had truly closed his chapter or left the door permanently open.

2. Gabriela Dawson – A New Life Away From Chicago

Gabriela Dawson’s departure was one of the most talked-about exits in the series.

After leaving Firehouse 51, Dawson moved to Puerto Rico to help with disaster relief efforts, choosing a life focused on humanitarian work rather than firefighting in Chicago.

Her relationship with Casey added emotional weight to her exit, and while she has appeared in limited returns, her long-term absence has made her one of the most “mysterious” post-exit figures in the franchise.
