In the highly anticipated premiere of Chicago Fire season 12, fans were finally given closure on Matt Casey's proposal cliffhanger from season 11. However, the resolution of this storyline has left many viewers disappointed as it comes at the expense of Sylvie Brett and her character development.

*SPOILER ALERT* The season 12 premiere, titled "Barely Gone," showcases Brett making a difficult decision to give up everything in Chicago and relocate to Portland with Casey after their engagement. This decision feels unfair to Brett's character as it seems one-sided, with her sacrificing her life while Casey maintains his status quo.

Over the past few years, Brett has experienced significant growth and challenges, particularly after Jesse Spencer's departure from the series. She has faced emotional turmoil, nurtured a relationship with a child, and pursued her paramedicine project. Through all of this, she has built a fulfilling life in Chicago surrounded by supportive friends and colleagues.

However, in a surprising turn of events, Casey proposes to Brett during his visit to Chicago. She accepts, and they plan to marry in a few weeks. Unfortunately, the compromise that follows leaves Brett disheartened. The couple decides that she will leave behind her job, support system, and the city she loves to join Casey in Portland. This uproots Brett from a familiar environment and forces her to leave behind her professional aspirations.

While there is undeniable love between Brett and Casey, the storyline feels unbalanced, with Brett making all the sacrifices. It is crucial for the show to establish that Brett isn't abandoning everything for Casey but rather that he is also making significant compromises to ensure a fair outcome for both parties involved.

The departure of Sylvie Brett from Chicago Fire is inevitable as actress Kara Killmer is leaving the One Chicago franchise. While giving Brett and Casey a happy future is a desirable outcome, it should not come at the expense of Brett's individuality and growth as a character. The show must find a way to write her out that does justice to her journey and showcases Casey making substantial sacrifices as well.

Chicago Fire, which launched the successful One Chicago franchise, has captivated audiences for 11 seasons. The series explores the lives and careers of public service employees in Chicago, specifically focusing on Firehouse 51's firefighters and paramedics. The ensemble cast includes talented actors such as Jesse Spencer, Taylor Kinney, Monica Raymund, and Eamonn Walker.

As Chicago Fire season 12 continues to air every Wednesday on NBC, fans wait with anticipation to see how Sylvie Brett's story unfolds and whether the show will address the inequality in her relationship with Casey in a satisfying manner.
