Kara Killmer may have left Chicago Fire, but she never left fans’ hearts.
After nearly a decade playing paramedic Sylvie Brett, Killmer’s farewell in Season 12 was nothing short of emotional. Her character’s love story with Matt Casey (Jesse Spencer) came full circle with a surprise wedding and move to Oregon—but even with that happy ending, fans are still hoping Brett’s story isn’t over.
Killmer’s final scenes reminded viewers why they fell in love with Brett in the first place: compassionate, strong, and fiercely loyal. The quiet moments she shared with the Firehouse 51 crew, especially with Stella Kidd (Miranda Rae Mayo) and Chief Boden (Eamonn Walker), were packed with heart and history.
Since her departure, Killmer has kept a relatively low profile—but recent interviews hint she’s open to a return. “You never know what the future holds,” she teased, sparking theories of a possible cameo in Season 13 or even Chicago Med.
The actress has also become an advocate for women in emergency services, using her platform to spotlight real-life first responders. With her growing influence off screen and lasting legacy on screen, Kara Killmer continues to be one of Chicago Fire’s brightest stars—even after goodbye.
