Sylvie Brett (Kara Killmer) is off to start a new life in Portland, but Firehouse 51 now lacks a paramedic to fill in the two-person job in Ambulance 61. Chicago Fire is ready to replace Sylvie and photos for Season 12, Episode 8, “All the Dark”, via TV Insider, tease a new partner for Violet. Wesam Keesh plays Lennox who can be seen with the crew responding to an emergency in a dialysis center. Chicago Fire showrunner Andrea Newman teased this development, saying:

“When Brett leaves, we have a position open on ambo, and there’s going to be some turnover there. So yeah, there’s somebody coming in as a new medic. What I can say is that Violet (Hanako Greensmith) becomes the PIC (Paramedic in Charge), so she gets to be the boss, and she’ll have to form the next person who comes in. It’ll be a journey finding that person. It’s not easy to replace Sylvie Brett.”

Chief Robinson (Laura Allen) promised Violet a new partner as she did not waste time. This replacement is bound to shake things up since Chief Robinson and Violet had a rough start, and while Violet is the natural replacement for Sylvie as Paramedic in Chief, Chief Robinson is not above bringing someone new. She made it clear that she did not need Violet’s input on who she planned to bring on board. It might present a real problem in the ambulance if Lennox and Violet don’t work well together as she did with Sylvie.
