The absence of Kevin Costner in Yellowstone season 5, part 2 will have significant negative effects on the popular show's ending. Rumors began circulating after the mid-season finale that Costner was unhappy with the creative direction of the series. It was reported that he refused to commit to the final episodes until he read an ending for his character, John Dutton, that he approved of.

Although there has been no official confirmation from Costner or the show's representatives, it is highly likely that John Dutton will die in season 5. Losing Costner's character will be a major blow to the show, as he is the central figure around which the other characters revolve.

The team behind Yellowstone will have to find creative ways to give John Dutton a proper send-off without Costner's presence. However, no amount of clever writing can replace the void left by his absence.

The absence of John Dutton will also impact several storylines in the show. The potential impeachment of John Dutton by his son Jamie will feel underwhelming without Costner's commanding presence. The long-standing feud between John Dutton and Thomas Rainwater will also lack resolution without Costner's involvement. Additionally, the dramatic climax of the feud between Jamie and Beth Dutton will be affected by Costner's absence.

The reveal of the Train Station, a dumping ground for the Dutton family's victims, will lose its impact without John Dutton's presence to take accountability. Jamie's efforts to implicate his father in past crimes will lack weight. Furthermore, the reconciliation between John and Jamie, as well as other characters' endings, will be affected by Costner's absence. The absence of John Dutton will also leave voids in the leadership of Yellowstone Ranch, with characters like Kayce and Monica possibly taking over. John's girlfriend, Summer Higgins, may also outlive her purpose without his presence. Furthermore, John Dutton will not live to see the prophecy revealed in the spin-off series 1883 come to pass.

His legacy project of using racehorses to protect the ranch will likely falter without his leadership. Finally, an off-screen death for a character as significant as John Dutton will be underwhelming and rob viewers of a proper send-off for Costner's beloved character.

Overall, the absence of Kevin Costner in Yellowstone season 5, part 2 will have a detrimental impact on the show's ending in several ways. The loss of his character will be deeply felt and will affect various storylines and character arcs. It is a disappointment for fans as they will be robbed of a fitting send-off for John Dutton.
