We Finally Know Why Casey Is Coming Back to Chicago Fire—And It's Surprising
His storyline for Season 11, Episode 18 may not be what you were thinking...
Chicago Fire fans were thrilled to learn that Jesse Spencer would be returning to the show as Matthew Casey for Season 11, Episode 18 (which airs Wednesday, April 5 at 9/8c on NBC and next day on Peacock). It's the first time fans will see his face since the Season 10 finale, when he and Brett (Kara Killmer) debated whether or not their long-distance relationship could keep working. Spoiler alert: It didn't, and by the Season 11 premiere, Brett and Casey decided to break up.
Spencer formally left the main Chicago Fire cast in Season 10, so this mini-return is exciting for fans. Granted, he's only slated to do this one episode, but that's better than no Casey at all, right?
The question remains, though, is what will Casey's role be in Season 11, Episode 18? Many are presuming his storyline will have something to do with Brett, and while that surely could happen—stay tuned!—the episode's logline tells a different, more surprising story.
Why Casey is coming back to Chicago Fire Season 11
If this description tells us anything, it's that Casey's main focus in the episode won't be Brett but actually work. Read for yourself, below.
“A familiar face returns to Firehouse 51 to serve with Kidd on a special task force; with Tony close to breaking the CFD's perfect attendance record, Mouch and Capp work to keep him safe; old grudges resurface when Gallo reunites with a family member.”
Yes, the "familiar face" in question is Casey, and it looks like he'll be working closely with Kidd (Miranda Rae Mayo) on some cases. But is that the only thing he'll be doing? You'll have to watch the episode to find out.
Spencer spoke with Us Weekly in 2022 about his decision to leave Chicago Fire.
“I realized I’ve been doing TV for a long time. I added it up, and I think this year  is my 18th year of network television... I called [showrunner] Derek [Haas] and broke him the news, said I thought it was time to leave the show, and he agreed that we should at least get Casey to 200 episodes," Spencer said. “It was a difficult decision because I’ve loved the show from the start, but there are other things that I would like to do in the future, and there’s some family that I need to take care of, and 18 years is a long time.”
