Marshals reintroduces Yellowstone fans to Kayce Dutton’s (Luke Grimes) new ride with U.S. Marshals as they protect Montana. But one important character is missing from the spinoff series: Monica Dutton, who was played by actress Kelsey Asbille in the original Paramount Network show. After viewers found out Monica died, fans asked why the creative team killed her off.
Luke even admitted in an interview that he was “incredibly bummed” that Kelsey wasn’t asked to reprise her role in Marshals. As Season 1 continues to air weekly, the finale is set for May 24, 2026, with a total of 13 episodes in the first season. The series has already been renewed for Season 2, meaning Kayce’s story will continue beyond the current run.
So, what happened to Monica, and why didn’t she return to the Yellowstone universe? Here is everything we know about Monica’s death.
After Monica and Kayce seemingly have their satisfying ending in Yellowstone, Marshals reveals in its season 1 premiere that she died of cancer, which she developed from toxicity on the reservation.
Luke told Entertainment Weekly that Monica was killed off to give Kayce a new motivation and some fresh “drama” in his journey.
“The way that Yellowstone ended for Kayce was literally he rode off into the sunset,” Luke told the publication in an interview following the Marshals season 1 premiere. “So, when he and the creative team started discussing the story behind Marshals, it was clear that something needed to change. Obviously, we can’t just watch this guy have his dream life. There’s no drama.”
Luke went on to say that “something” needed to happen to get in the way of Kayce’s picture-perfect life, “Otherwise, why is he gonna take a badge? The last time we saw him, he was throwing a badge in a field. Is he gonna go pick it up?”
