John Dutton, the central character in the Yellowstone universe, is dead, but fans wonder if Kevin Costner might appear in flashbacks in Y: Marshals, the new CBS spinoff focusing on Kayce Dutton.
Y: Marshals follows Kayce Dutton, expanding the Yellowstone storyline. With Costner’s character deceased in the main series, the possibility of his return would be limited to non-linear storytelling elements like flashbacks.
No official confirmation has been given about Costner’s involvement in Y: Marshals. The narrative direction seems to focus primarily on Kayce’s journey rather than revisiting John Dutton directly.
“John Dutton is a powerful figure in the Yellowstone saga, but his story arc has reached its natural conclusion,” said a source close to the production.
While the idea of Kevin Costner reprising his role as John Dutton in Y: Marshals intrigues fans, it remains uncertain and likely limited to flashback scenes rather than a full return.
Kevin Costner's involvement in the Yellowstone spinoff is unconfirmed but, if it happens, will probably be through brief flashbacks, keeping the focus on Kayce Dutton’s storyline.
