Chicago Fire alum Kara Killmer has once again captured the hearts of fans, this time not with her acting but with her

remarkable singing ability. A delightful fan-made compilation recently surfaced, showcasing the vocal talents of the

One Chicago cast, and Killmer’s performance is a standout moment.

In the video, Killmer delivers a mesmerizingly sweet rendition of “Over the Rainbow,” which begins around the 3:35 mark. What’s particularly impressive is the way she seamlessly floats her voice through the song while simultaneously working away on her laptop—a feat that truly highlights her multitasking prowess and raw talent.

The compilation is a celebration of the musical capabilities of numerous actors from the One Chicago universe, presenting a treasure trove of vocal and musical moments that fans will treasure. With this showcase of talent, many fans are now eagerly crossing their fingers for a full-blown musical crossover special within the One Chicago franchise—a concept that certainly has a lot of appeal.

Farewell to Chicago Fire

In other news, Kara Killmer’s departure from Chicago Fire marks the end of an era, as she steps away from her role as paramedic Sylvie Brett after ten successful seasons. While her absence will undoubtedly be felt in the upcoming seasons, Killmer remains optimistic about her future endeavors.

Reflecting on the close-knit relationships formed during her time on the show, she told NBC Insider, “This cast is definitely very familiar with losing people that we love. There is such a core principle of humor and friendship that continues to keep [us] going; I think that’s what’s really special about our show in particular. [One Chicago franchise creator Dick Wolf] is very intentional about making sure that the people who work on our show… have a good sense of humor.”

Despite her official farewell to the cast and crew, Killmer left the door open for a potential return. “Any time they wanna call, I will be there,” she stated. “It is a fantastic show; great people. I will come back anytime they want.”

As fans say goodbye to Sylvie Brett, they can take comfort in the possibility of Killmer’s return and the fond memories she leaves behind. In the meantime, her enchanting musical performance serves as a delightful reminder of the talent that graces the One Chicago series.
