@cbsmornings: Actor Luke Grimes, who played Kayce Dutton in “Yellowstone,” now stars in the spinoff “Marshals,” where a huge event leaves his character reeling and forced to confront what comes next. Grimes says he was “pretty heartbroken” when he first heard about the direction of Kayce’s story, calling it the emotional "motor" of the new series as his character grapples with grief and searches for a new purpose. ##lukegrimes##yellowstone##marshals##kaycedutton
