Spoilers for the series premiere of Marshals are ahead! You can stream the episode with a Paramount+ subscription, and then catch new ones every Sunday at 8 p.m. ET on CBS.
As our first post-Yellowstone spinoff kicked off on the 2026 TV schedule, we got to see the returns of Luke Grimes as Kayce Dutton, Gil Birmingham as Thomas Rainwater, Mo Brings Plenty as Mo and Brecken Merrill as Tate Dutton. However, one notable Yellowstone cast member who was missing from this lineup was Kelsey Asbille, who played Kayce’s wife, Monica. Now, Grimes has opened up about why her character isn’t on the show, why it’s good for it and his personal reaction to the development.
