The highly anticipated 2025 One Chicago crossover may bring devastating news for fans of Chicago Fire, as Taylor Kinney’s Kelly Severide appears to be on the brink of losing someone close to him. This year’s crossover marks the franchise’s first in five years, uniting characters from Chicago Fire, Chicago Med, and Chicago PD in a high-stakes event centered around a massive transportation disaster in Chicago.
While the One Chicago shows have primarily told separate stories in recent years, this crossover promises a more character-driven narrative, with several key players facing life-threatening situations. Among them, Severide seems destined for heartbreak.
The Trailer Hints at Tragedy for Severide
NBC recently dropped the official trailer for the 2025 crossover, teasing its dramatic premise. The footage highlights a catastrophic train accident and features several emotional moments, including a heart-wrenching clip of Severide in tears. While it has been confirmed that Stella Kidd will be among those trapped in the wreckage alongside Chicago PD’s Adam Ruzek, Severide’s anguish is unlikely to stem from concern for his wife.
Severide and Kidd have faced numerous life-or-death situations throughout Chicago Fire, always maintaining composure and emerging stronger together. The trailer’s depiction of Severide’s breakdown hints at a deeper, more personal loss—potentially the death of his estranged brother, Jack Damon.
The Tragic Arc of Jack Damon
Introduced in Chicago Fire Season 12 as Benny Severide’s secret son, Jack Damon initially shared a promising bond with Kelly. Their relationship allowed Kelly to step into a mentoring role and opened the door to new storytelling opportunities for the show. However, Damon’s stint at Firehouse 51 was short-lived. After a series of insubordinate actions and conflicts with Stella Kidd, Damon was ultimately fired by Chief Dom Pascal.
Despite his departure from Firehouse 51, Damon remains active as a firefighter and could easily be involved in the response to the transportation disaster. Whether he’s part of a first-responder team or an unfortunate commuter caught in the chaos, Damon’s potential death would deeply affect Severide.
What Jack Damon’s Death Could Mean for Severide
Losing Jack would be a devastating blow for Severide, who has only recently started to build a relationship with his half-brother. Damon’s death could force Severide to confront lingering feelings of guilt and loss, reshaping his character’s arc moving forward.
One possible outcome is a renewed desire for Severide to start a family. Since reconnecting with Damon, he has embraced the role of a mentor and protector, suggesting that he might be ready to fill that void in his life by having children of his own. However, this decision should come from a genuine desire rather than being driven by grief.
Stella Kidd’s perspective is crucial in this equation. As someone still recovering from the trauma of being trapped in the train disaster, she may not be ready to take such a significant step. Their ability to navigate this delicate situation together could serve as an important storyline for Chicago Fire moving forward.
Chicago Fire’s Track Record with Tragic Losses
If Damon’s death does occur, it would align with Chicago Fire’s history of shocking and emotional character exits. The show has frequently used untimely deaths to remind viewers of the risks faced by first responders. The last major loss occurred when Chief Evan Hawkins, Violet Mikami’s love interest, died in the line of duty.
While killing off a main character like Severide or Kidd is unlikely, Damon’s death offers a way to raise the stakes without disrupting the core ensemble. His connection to Severide ensures that the tragedy would have a lasting emotional impact on both the character and the audience.
As the One Chicago crossover approaches, fans are bracing for an emotional rollercoaster. The event promises to deliver high-stakes action, heart-pounding drama, and potentially life-changing consequences for Kelly Severide and those closest to him.
