After five dramatic seasons, with the final one split into two parts, Yellowstone ended in December 2024. Fast-forward to 2026, and CBS is preparing to debut its first Yellowstone spinoff, Marshals, starring Luke Grimes reprising his role as Kayce Dutton. Here, we’re recapping Yellowstone‘s final season — Kayce and his family’s endings in particular — to help refresh your memory before Marshals premieres. How did Yellowstone end? Yellowstone‘s final season (Season 5 Part 2) began with the murder of John Dutton (Kevin Costner), and the rest of the season depicted the fallout. Another Dutton died by the end, when Beth (Kelly Reilly) and Jamie’s (Wes Bentley) series-long rivalry finally came to a violent head.
