The high-stakes world of the Yellowstone universe has once again proven that no character is safe. In a jarring turn of events during the May 10 episode of the CBS series Marshals, viewers witnessed a Marshals surprise character death that shifted the emotional weight of the season and settled a long-standing mystery from the protagonists’ shared past.
The episode, which continued to explore the volatile life of Kayce Dutton (Luke Grimes), blended present-day tension with haunting flashbacks to the characters’ military service. While the series has already established a pattern of grief, the sudden loss of Garrett (Riley Green) serves as a poignant reminder that tragedy remains a constant companion for Kayce, even as he navigates his new role protecting Montana.
As a spin-off and sequel to the massive hit Yellowstone, Marshals has leaned heavily into the theme of legacy and loss. The death of Garrett is not an isolated shock but part of a broader narrative arc designed to test Kayce’s resilience as he balances his duties as a U.S. Marshal with the burdens of his personal history.
The Unexpected Passing of Garrett
The May 10 episode picked up in the wake of a prison bus crash, with Kayce and Cal (Logan Marshall-Green) working to track down the final remaining inmate on the loose. However, the episode’s most devastating blow occurred away from the action, in a quiet hospital room.
Garrett had been recovering from a ranch fire at Kayce’s home, where he sustained second-degree burns and suffered from significant smoke inhalation. Throughout the episode, it appeared he was on the road to recovery. However, the narrative took a sharp turn when Kayce, Cal, and Andrea (Ash Santos) returned to the hospital at the conclusion of their shift, only to be informed that Garrett had died.
This sudden exit is particularly impactful given that the role of Garrett marked the acting debut of country music star Riley Green. Green had appeared in multiple episodes this season, bringing a new energy to the ensemble. In a statement released in February, Green expressed his excitement about joining the production, noting that working alongside his friend Luke Grimes made his introduction to the acting world a memorable experience.
Flashbacks and the Navy SEAL Revelation
The tragedy of Garrett’s death was layered with a revelation about the characters’ time as U.S. Navy SEALs. Through a series of flashbacks, the episode explored a controversial incident from their past involving the death of a fellow teammate.
For some time, there had been tension regarding who was responsible for declaring a wounded teammate dead during a mission—a call that effectively prevented the soldier from receiving lifesaving medical intervention. The flashbacks revealed that the blame did not lie with Cal, as previously suspected. Instead, it was Garrett who made the decision to declare the teammate dead, a choice that ultimately resulted in the friend’s passing.
This revelation added a complex layer of guilt and irony to Garrett’s own death. By the time Kayce and Cal learned the truth about the mission, Garrett was already gone, leaving the survivors to grapple with a truth that can no longer be confronted or resolved through dialogue.
A Pattern of Tragedy for Kayce Dutton
The loss of Garrett follows an even more devastating blow delivered at the start of the season. When Marshals premiered on CBS on March 1, 2026, audiences were stunned to learn that Kayce’s wife, Monica (Kelsey Asbille), had died off-screen after a battle with cancer.
Showrunner Spencer Hudnut has been transparent about the creative decision to introduce such a significant loss. In a March interview with TVLine, Hudnut explained that while Kayce had achieved a “perfect ending” in the original Yellowstone series, the new chapter of his story required him to be “shaken out of that.” Hudnut noted that tragedy tends to find Kayce, and the loss of Monica was a necessary catalyst for his current journey.
According to Hudnut, Monica’s presence continues to influence Kayce’s path. He highlighted that Kayce’s decision to protect his son, Tate, at a rally honoring Monica is what ultimately positioned him to find his current trajectory. The showrunner emphasized the importance of being respectful to the character’s exit while acknowledging that “real life intervened” regarding the production’s direction.
Key Plot Developments in ‘Marshals’ Season 1
- The Premiere Twist: The off-screen death of Monica Dutton due to cancer.

- The Hospital Tragedy: Garrett’s unexpected death following injuries sustained in a ranch fire.

As the series progresses, the cumulative weight of these losses—both the long-term grief of Monica’s passing and the sudden shock of Garrett’s death—continues to define Kayce’s psychological landscape. The series uses these deaths not merely for shock value, but to explore the themes of duty, forgiveness, and the enduring nature of trauma.
With the series already renewed for a second season, the fallout from these events is expected to drive the narrative forward, as Kayce continues to raise Tate alone while navigating the dangers of his profession.
Marshals continues to air on CBS Sundays at 8 p.m. ET. Stay tuned for further updates on the series and upcoming episode developments.
