“Goodbye, Brett — But Never Forgotten”: Kara Killmer’s Exit Leaves a Lasting Mark on Chicago Fire

After nearly a decade of saving lives, healing hearts, and anchoring Chicago Fire with compassion and grace, Kara Killmer has officially said goodbye to Firehouse 51 — and fans are still feeling the heartbreak.

As paramedic Sylvie Brett, Killmer brought more than medical skill to Ambulance 61 — she brought soul. From her emotional strength to her unwavering care for others, Brett quickly became one of the most beloved characters in the One Chicago universe. And after years of will-they-won’t-they tension, her long-awaited wedding to Matthew Casey (Jesse Spencer) gave fans the bittersweet closure they’d been hoping for — but it didn’t make her farewell any easier.

Kara’s final episodes were filled with the quiet power that’s defined her performance from day one. Her goodbye wasn’t flashy — it was real, heartfelt, and deeply in line with the Brett we’ve come to love. And the moment she said “I do” to Casey? It felt like a reward for fans who’ve rooted for #Brettsey since the beginning.

Off-screen, Kara Killmer’s impact is just as lasting. Known for her warmth, sense of humor, and genuine love for the Chicago Fire family, she’s remained a favorite among cast, crew, and viewers alike. Her exit may be official — but in the hearts of fans, Sylvie Brett is forever part of Firehouse 51.
