Then there was the epic One Chicago crossover event “In the Trenches”, which was one of the franchise’s best. Kidd (Miranda Rae Mayo) and Severide (Taylor Kinney) work towards adopting a baby, coming close before having the rug pulled out from underneath them. Carver and Ritter (Daniel Kyri) aren’t returning next season, adding another layer of speculation as to how they would be bowing out. The Season 13 finale did some great work in tying up loose ends heading into next season — apart from still no indication of how Ritter ends up leaving — and introducing some intriguing new storylines. What I believe Firehouse 51 needs this upcoming season is serenity now (yes, I heard it), and one way to do it is to bring home Matthew (Jesse Spencer), Sylvie (Kara Killmer), and the rest of the Casey clan. And the timing couldn’t be better.
“Brettsey” Tied the Knot Before Leaving ‘Chicago Fire’ in Season 12
Only for Brettsey to survive, they’d have to navigate the perils of the long-distance relationship, with Casey moving to Oregon to be a stand-in parent for his late teammate’s two sons. They gave it the old proverbial college try, but in the Season 11 premiere, Brettsey, again, was over. Over the course of the season, Brett decided to adopt a baby, which sent her then-boyfriend running. The timing couldn’t be better, with Casey in town. After hearing about it, Casey made his way to Brett’s and proposed in the Season 11 finale, saying, “Sylvie Brett, we were meant to be. Will you make me and the three kids the luckiest family in the world? Marry me.” The answer was going to have to wait until the Season 12 premiere, revealing that she did, indeed, say yes. Hence, the aforementioned wedding, and the end of the long-distance relationship with Brett, now Casey (and who shall henceforth be Sylvie), moved to Portland, putting an end to their Chicago Fire days.
The Timing is Right for the Return of Brettsey to ‘Chicago Fire’
For starters, Casey left Firehouse 51 to move to Oregon to take care of the Darden boys, promising to take care of them until Ben (Liam Booth) turns 18 and can go to school in Chicago. That was three years ago in 2022, and if you add Ben’s age at the time, 15, and 3, where — and even yours truly can do the math — you get the magic 18. He can go to school in Chicago, and the whole family can come with. Depending on what happens with Violet, there could potentially be an opening for Sylvie at Firehouse 51, and with both Carver and Ritter leaving, there would be holes where Casey fits in, so that’s not an issue. Showrunner Andrea Newman has even said the door’s open, and we’ll find out more about Brettsey in the new season. So the question isn’t how they get back, it’s why.
