It’s finally happening! Sylvie Brett (Kara Killmer) and Matthew Casey (Jesse Spencer), affectionately dubbed “Brettsey” by fans, are tying the knot on the next episode of Chicago Fire. After years of emotional ups and downs, breakups and reunions, the beloved couple is set to say “I do” in a momentous episode airing this Wednesday.
Parade has shared an exclusive first look at two photos from the much-anticipated wedding episode, and the images capture the heartfelt culmination of a love story that has been years in the making.
From Proposal to Wedding Bells: Brettsey’s Journey
Casey proposed to Sylvie in the dramatic Season 11 finale. Despite their earlier breakup, Sylvie said yes, marking a pivotal moment for the couple. This union also serves as a touching farewell for Sylvie, as Kara Killmer departs the series. In the storyline, Sylvie and Casey will start their new life together in Portland, Oregon, where Casey has been raising the sons of his late friend, Andy Darden.
The wedding itself will be an intimate affair. Sylvie insists on keeping the ceremony small, inviting only close friends and family. While her Firehouse 51 coworkers are thrilled for her, they’re understandably saddened by her earlier-than-expected exit.
A Romance Full of Challenges
Brett and Casey’s love story has been anything but straightforward. Their initial connection was complicated by Casey’s relationship with Gabby Dawson (Monica Raymund), his eventual ex-wife. Despite her attraction to Casey, Brett adhered to the “girlfriend rule”—never date a friend’s ex.
Over time, their friendship deepened, but Brett pursued other relationships, including a brief engagement to Chaplain Kyle Sheffield (Teddy Sears). After moving to Indiana with Kyle, Brett realized it wasn’t meant to be and returned to Chicago.
Meanwhile, Casey was adjusting to life as a foster parent for Andy Darden’s sons, a responsibility that eventually led him to leave Chicago for Portland. Despite their undeniable chemistry, long-distance dating proved too challenging, and they decided to part ways in Season 10, with Brett lamenting that their “stars just didn’t align.”
A Reunion Worth the Wait
Their paths crossed again when Casey returned to Chicago to be Kelly Severide’s best man. Though their time together rekindled feelings, the strain of a long-distance relationship remained evident.
After Brett tried to move on with Dylan (Christopher Allen) and started pursuing adoption on her own, Casey heard she was single again. Determined to make things right, he flew back to Chicago in the Season 11 finale and proposed, assuring Brett that he fully supported her decision to adopt.
“Sylvie Brett, we were meant to be,” Casey said during the heartfelt proposal. “Will you make me and the three kids the luckiest family in the world? Marry me.”
Brett’s answer was an emphatic “yes,” setting the stage for their upcoming wedding.
A Happy Ending for Brettsey
After years of trials, heartbreak, and perseverance, Brettsey fans will finally witness their favorite couple’s happy ending. While Brett’s departure marks the end of an era for Chicago Fire, her journey with Casey promises a future filled with love and new beginnings.
Tune in this Wednesday to witness the momentous occasion and celebrate the union of Sylvie Brett and Matthew Casey—an unforgettable chapter in the Chicago Fire saga.
