Warning: The following contains MAJOR spoilers for Yellowstone Season 5 Episode 10, “The Apocalypse of Change.”] Luke Grimes told TV Insider ahead of the premiere of Yellowstone‘s final season that John Dutton’s (Kevin Costner) fate forces Kayce to pick a side in the civil war between his siblings.

However, such an assumption perhaps unfairly ignores the secret weapon that has helped Jamie survive within this family for along as he has. And it’s not exactly the kind of thing that Beth and Kayce can properly plan for.

In Sunday’s Yellowstone, Jamie celebrated John’s death by making plans to hand over the ranch to Market Equities and, for good measure, having sex with Sarah on the desk of the attorney general’s office.
