Summary

• Brett's final Chicago Fire episode will air in episode 6, "Port In The Storm," marking her sendoff.
• Brett's departure from Firehouse 51 has long been determined, with Killmer's exit confirmed.
• Expect chaos leading up to Brett and Casey's wedding, setting the stage for her farewell.

Kara Killmer's final Chicago Fire season 12 episode as Sylvie Brett has been revealed. Surprisingly, One Chicago was still able to take a one-week hiatus in an already shortened season, allowing those who weren't caught up with the show the time to do so. As exciting as it is that a new episode of Chicago Fire season 12 is set for this week, it also brings the series closer to Brett's sendoff.

Co-showrunner Andrea Newman has teased about Brett's arc in Chicago Fire season 12, promising that she will be in a good chunk of the year. However, proof that her departure is creeping up is the confirmation that Killmer's final appearance will be in episode 6, "Port In The Storm," as revealed by its official synopsis from NBC (via SpoilerTV). Read the full brief below:

Firehouse 51 welcomes back some familiar faces and says goodbye to Brett. Violet scrambles to decorate Brett's wedding venue. A call at the expo center takes a shocking turn.

What To Expect From Brett’s Final Chicago Fire Episode

Brett's exit from Firehouse 51 has long been determined. Killmer's departure from One Chicago was reported ahead of the Chicago Fire season 12 premiere, with the actor even sharing behind-the-scenes content on her social media to celebrate her last few months with the show. Matt Casey's proposal in the Chicago Fire season 11 finale sets the stage for an easy way to write her out. The pair will get married in Chicago, mandating Jesse Spencer's return, which had been confirmed by a recent set image. After the ceremony, Brett and Baby Julia will move to Oregon to be with her new husband.

Between this and a recent Chicago Fire season 12 set video offering an early look at Brett and Casey's wedding at Molly's, it's safe to say that Killmer's stint will be capped off by the ceremony. Unless the pair stays in Chicago for a bit longer, then there's really no reason to hold onto them, considering that their move has already been set in stone. Like Kelly Severide and Stella Kidd's wedding episode in the Chicago Fire season 10 finale, expect that the events leading to the ceremony will be a bit chaotic.

For context, Chicago Fire season 12, episode 5 is set to be released this week. This means that Brett's wedding and eventual sendoff is just a week and a half away. Whether there will be a prior setup for it or if it will be a contained storyline is currently uncertain. However, expect that One Chicago will make the most out of its remaining time with such a beloved cast member like Killmer.

Chicago Fire season 12 airs new episodes every Wednesday, 9pm ET on NBC.
