As a spin-off of Yellowstone, Marshals often weaves in callbacks to the original series, but this week's episode, "Secret Weapon," takes it a step further by having Kayce Dutton (Luke Grimes) directly reference his late brother, Jamie Dutton (Wes Bentley). It's a moment that fans of the franchise won't want to miss.
While interrogating a runaway named Will McCoy (Keean Johnson), Kayce draws a parallel between Will and Jamie, noting that both were considered the "black sheep" of their families. He even mentions how Jamie was tormented by their sister Beth (Kelly Reilly), much like Will's older brother mistreats him. The comparison serves a practical purpose—Kayce is trying to locate a bomb planted by Will's brother—but it also reveals a rare glimpse into Kayce's feelings about Jamie's death.
What's particularly striking is that Kayce uses Jamie's story as a cautionary tale, suggesting that his brother "went and made his own life" after being pushed away. This is a subtle but significant shift, as Marshals has largely avoided addressing Jamie's demise since the events of Yellowstone's final season.
Jamie's death was a major plot point in the original series, but the spin-offs have mostly glossed over it. Kayce grieved his father John (Kevin Costner) and his unborn son, but Jamie's passing was never fully explored. This week's episode hints that Kayce is still processing that loss, even if he doesn't say it outright.
Given that Kayce now works in law enforcement in Montana, it's surprising that Marshals hasn't delved deeper into the mystery of Jamie's disappearance. Harry Gifford (Brett Cullen) has shown interest in the deaths of both John and the state's attorney general, but the show hasn't pursued that thread. It feels like a missed opportunity to explore Kayce's internal conflict between his family's dark past and his new path.
Fans of the Yellowstone universe have been eager to see how Kayce copes with the legacy of his family's actions. Jamie's death, orchestrated by Beth, remains a loose end that could provide rich storytelling. Perhaps a future crossover with Dutton Ranch could finally address it, but for now, Marshals seems content to let Kayce bury his feelings.
As the series continues, it's clear that Kayce's past will keep resurfacing. Whether that leads to a deeper exploration of Jamie's fate or remains a subtle nod, it's a reminder of the complex web of relationships that defined Yellowstone. For now, fans can enjoy this brief but meaningful callback.
Marshals airs Sundays on CBS and streams the next day on Paramount+. For more on the Yellowstone universe, check out our coverage of the season 2 premiere's ratings and Kevin Costner's upcoming projects.
