The possibility of John Dutton's death in the upcoming season of Yellowstone is becoming more likely, according to star Kelly Reilly. Kevin Costner, who plays John, has announced his exit from the show due to behind-the-scenes issues. While a sequel series is in the works, the main series will conclude after the upcoming season 5 part 2. Reilly's comments suggest that the ending of Yellowstone will be bittersweet, aligning with the show's history and creator Taylor Sheridan's previous work. It is anticipated that John Dutton's death will occur as the ranch is lost, as prophesied in the prequel series 1883.
