The March 22 episode of Marshals featured Kayce and Cal rescuing a rancher from a helicopter crash, leading to an offer from the rancher's daughter, Dolly Weaver. The episode also revealed that bartender Maddie is Cal's estranged daughter. Actors provided insights on Kayce moving on after his wife Monica's death.
In the March 22 episode of Marshals season 1 episode 4, U.S. Marshals Kayce and Cal undertook a mission to rescue a wealthy rancher, played by guest star Chris Mulkey, after his helicopter crashed into a mountain. Grateful for saving her father's life, Dolly Weaver (guest star Ellyn Jameson) offered to buy the team drinks and showed particular interest in Kayce. Andrea warned Kayce, saying, 'I know what grateful looks like, and that is not how she's eyeing you. Saddle up, cowboy.' Dolly later approached Kayce, commenting that his skills apparently 'don't include being the life of the party.' New to Montana, she requested a private 'crash course on all things Big Sky,' to which Kayce replied, 'Maybe.' Dolly's father is assisting Kayce with his ranch, potentially leading to further interactions. This development comes shortly after the death of Kayce's wife Monica, a character from Yellowstone, which occurred before the Marshals series premiere. Actor Mo Brings Plenty, who plays Mo, noted that Kayce 'now has to carry on his wife's legacy' and is 'getting even more involved now because he has to fill the space she left behind.' He added that from a traditional perspective, Mo would have an opinion but would support Kayce as a brother. Brings Plenty viewed Monica's cancer storyline positively, linking it to real environmental issues affecting all people. The episode also disclosed that bartender Maddie (guest star Morgan Lindholm), previously thought to be Cal's flirtation interest, is his daughter, resolving the mystery of a photo in Cal's wallet. Earlier, actor Marshall-Green had said of Cal, 'He's looking for love, and he's hoping Maddie is going to love him. She's definitely putting up a fight.' Showrunner Spencer Hudnut teased that the photo explains Cal's move to Montana.
