The milestone 200th episode of Chicago Fire, titled “Two Hundred,” aired on October 8, 2021, marking a significant moment in the show’s history. Not only did it celebrate

the series reaching 200 episodes, but it also served as the final appearance of Captain Matt Casey, portrayed by Jesse Spencer. After dedicating 10 years to Chicago Fire and another eight years

on House, Spencer decided to leave the show to take a break, signaling the end of his journey with Firehouse 51—for now.

While Spencer left the door open for a possible return, “Two Hundred” brought a bittersweet end to the beloved “Brettsey” relationship between Casey and paramedic Sylvie Brett (Kara Killmer). The couple had been through so much together, and with Casey moving to Portland, the future of their romance was left uncertain. The episode focuses on Casey breaking the news to his colleagues at Firehouse 51, and most notably, his farewell to Brett. The emotional weight of the scene was felt deeply by fans, especially those who had long supported the couple’s relationship.

The most heart-wrenching moment comes midway through the episode, when Casey and Brett have a tearful conversation about their future. Casey reassures Brett that despite the distance, his feelings for her won’t change. “I know I have you supporting me,” he tells her, “Whether that’s right here or halfway across America, nothing’s going to change.” The scene ends with a tender kiss, encapsulating the depth of their bond and the heartache of their separation.

Fans on social media expressed their emotions about the powerful moment. One user, @burgesylvie, tweeted, “This scene was so cute and I’ll miss them so much. Rest in peace my beloveds,” sharing a GIF of a woman sobbing. Another fan, @bellaontheave, echoed the sentiment, adding, “I wish Twitter had a thumbs down,” reflects how deeply the loss of Brettsey affected them.

While Casey and Brett’s relationship may face an uncertain future, this pivotal moment stands as one of the most emotional highlights in the Chicago Fire universe. The episode brought an end to a significant chapter in the lives of these characters, leaving fans eagerly awaiting what comes next for them—and for the dynamic world of Chicago Med, Chicago Fire, and Chicago P.D.
