How John Dutton’s presence lingers in new Yellowstone spin-off Marshals after Kevin Costner’s role was killed off

Despite his shocking death in the final season of Yellowstone, rancher John Dutton remains a presence in the new spin-off about his family. John, played by Kevin Costner, was killed off in a murder-for-hire plot in the fifth and final season of Yellowstone. 

Being a member of the family, however, appeared to be something Kayce (Luke Grimes) kept close to his chest while serving in the military. ‘All those years of door-kicking, you never once mentioned that you’re some Montana Rockefeller,’ Kayce’s pal and former Navy SEAL teammate Pete Calvin (Logan Marshall-Green) told the Dutton, according to People.’That was the best part about being a SEAL. Being a Dutton didn’t matter,’ Kayce replied.
