Firehouse 51 paramedic Sylvie Brett received good news and bad news during the Season 11 finale — including a surprise proposal that pulled on our heartstrings. Is Sylvie Brett leaving Chicago Fire? There’s a good chance that Season 12 could be her last, especially with the return of Casey and his latest offer to her. Keep reading to learn more.
Chicago Fire is NBC’s first responder-centered drama series that spotlights the professional and personal lives of firefighters, rescue personnel and paramedics of the Chicago Fire Department’s fictional Firehouse 51. Produced by Dick Wolf, the show is currently in its 11th season and was recently renewed for Season 12 in April 2023 (along with the other One Chicago shows, Chicago P.D. and Chicago Med).
Actress Kara Killmer plays Sylvie Brett, the Ambulance 61 paramedic who transferred to Firehouse 51 in Season 3 to replace the late Leslie Shay after her tragic death. She was in a relationship with Captain Matthew Casey (Jesse Spencer), who was a series regular on the firefighter drama until Spencer left the show in Season 10. (Spencer has reprised his role as a guest star on numerous occasions throughout Season 11.)
Brett and Casey’s started seeing each other officially in Season 9, but their relationship went downhill when Casey moved to Oregon to be with Andy Darden (Corey Sorenson)’s two sons. The couple decided to try long distance during that time, but in the end, it was too difficult for Brett to keep up with. Brett broke up with Casey over the phone in Season 11, Episode 1, “Hold On Tight.”
In an interview with NBC Insider in September 2022, Killmer said she was excited to explore her character following her breakup with Casey. “It’ll be interesting to see her really dedicate herself to her career,” she said. “And I think we’ve always seen Sylvie in a relationship. We’ve always seen her in a romance. She’s a hopeless romantic, but I think it’s important to see her come into her own and focus on her own things. Friendships and her career, not just her love life. I’m really excited about being able to explore all of that.” Since then, her character started dating Dylan (Christopher Allen), which became more complicated when Casey returned to Firehouse 51 in Season 11. (And he’s expected to come back for the Season 11 finale, too).
