Firehouse 51 legend and all-around loving man Matthew Casey (Jesse Spencer) caused quite the upset for Chicago Fire fans in October 2021 when he left the show. As the love interest of Sylvie Brett (Kara Killmer) and the Captain of Firehouse 51, it came as a shock when Casey moved to Portland to look after his late best friend Andy Darden's young sons.
With many series regulars coming and going throughout the years, Casey leaving Chicago has many One Chicago fans curious about future seasons. Is Casey leaving Chicago Fire forever? Will Casey and Brett stay together? Is there a chance he might come back? Now that Season 10 is wrapped—and Jesse Spencer appeared in the finale—NBC Insider explores the unclear future of Casey's character.
Is Casey leaving Chicago Fire for good?
The answer to that question is a mystery—for now. While Spencer did make a highly-anticipated cameo in the Chicago Fire Season 10 finale—after leaving the show after its 200th episode—it remains unclear if this was a one-off appearance or if there will be more appearances in the future. At the Stellaride wedding, Casey and Brett questioned how long they'd feasibly be able to keep dating with the former in Portland and the latter in Chicago. Both are incredibly happy in their respective cities, which puts the future of their relationship—and Casey's future on Chicago Fire—in question.
What we do know is Spencer told USA Today back in October 2021 about leaving Chicago Fire, "It was a difficult decision because I've loved the show from the start...But there’s other things I’d like to do in the future and there’s some family I need to take care of."
