Kara Killmer will return to the NBC drama in Season 12 — but it will be her last year as paramedic Sylvie Brett, TVLine has learned. The exact timetable/episode for her exit has not been revealed yet.

Killmer joined Fire in the Season 3 premiere, filling the void left by the death of Lauren German’s character, paramedic Leslie Shay. The actress has appeared in 193 episodes of Fire during her nine-season run, plus over two dozen installments of spinoffs Chicago Med and Chicago P.D.

As a medic at Firehouse 51, Brett had her share of partners on Ambulance 61, including Gabby Dawson and Peter Mills, before she was eventually promoted to Paramedic in Charge following the exit of her third partner, Chilli. (Others to ride alongside Brett included Jimmy Borrelli, Gabby again, and Gianna Mackey). Mostly recently, Brett worked alongside Violet Mikami.

On the relationship front, Brett has of late been in an on-and-off relationship with Matt Casey (played by former series regular Jesse Spencer). In the May 24 season finale, Casey popped the question to his ex-girlfriend, but the episode ended before she could give her answer. (Relatedly, we have a dream spinoff pitch for how that cliffhanger could play out.)
