The highly anticipated Season 12 premiere of "Chicago Fire" is just around the corner and fans are itching to know what's in store for their favorite characters. One storyline that has piqued curiosity is the romantic roller coaster involving paramedic Sylvie Brett, portrayed by Kara Killmer.

In the finale of last season, viewers were left on the edge of their seats as firefighter Matt Casey, played by Jesse Spencer, proposed to Brett. The photos from the upcoming premiere reveal a ring on Brett's finger, confirming that she said yes. However, Executive Producer Andrea Newman warns not to get too excited just yet.

Newman explains that when we first see Brett in the premiere, it becomes evident that her plans are not going as smoothly as expected. As in real life, things don't always go as planned, and this rings true for Brett's love life.

While Brett's plans for a successful adoption have worked out wonderfully, with the baby Julia becoming a cherished part of both Brett's life and the firehouse's 51 family, there are still challenges ahead for her romantic relationship.

What complicates matters further is the knowledge that Killmer will be exiting the show at some point in Season 12. The distance between Brett and Casey was a factor in their breakup, and it remains to be seen if they can make their relationship work this time around. Newman remains tight-lipped about the details, only hinting that Brett's plans don't unfold as expected.

However, one thing fans can look forward to is the return of Jesse Spencer as Matt Casey. Newman reveals that Casey will definitely be making appearances throughout the season, reassuring fans that their beloved character remains a significant part of the "Chicago Fire" storyline.

As for Killmer's departure, Newman shares that the actress will be present for a substantial portion of the season. Brett's character will showcase her heroic skills early on, ensuring fans won't miss out on her action-packed performances before her departure.

The Season 12 premiere of "Chicago Fire" is set to air on Wednesday, January 17th at 9/8c on NBC. Brace yourselves for a tumultuous journey as Sylvie Brett navigates the obstacles in her romantic life and bids farewell to the firehouse she has called home.
