Marshals is expanding its cast in Season 2 with the arrival of Scarlett Burke, who will portray a recurring character named Shelby Gaines. The actress and country music singer is joining the CBS series as a Texas cowgirl whose spirited personality hides deeper emotional wounds.
Burke’s character will make her debut in Season 2, Episode 8, scheduled to air on Sunday, November 29, at 8 p.m. ET/PT. Shelby arrives at East Camp to work with Kayce Dutton (Luke Grimes), bringing a new presence to the ranch and becoming involved in one of his latest initiatives.
Who Is Shelby Gaines?
Shelby is a transplant from Texas who comes to East Camp to help Kayce establish an equine therapy program. Although she is described as feisty and strong-willed, her personality also conceals a more vulnerable side.
Her arrival gives Kayce another person to work alongside as he continues building his life and responsibilities beyond his work with the Marshals. The new character is expected to become a recurring part of the series rather than appearing in just one episode.
TV Insider has also offered an exclusive first look at Burke alongside Grimes in the upcoming installment, giving viewers an early glimpse of the new cowgirl before her on-screen introduction.
What Happens in Season 2, Episode 8?

Shelby’s debut takes place during an action-packed episode that brings another dangerous assignment for the Marshals. The team becomes caught in a shootout connected to a diamond heist after being tasked with capturing an international fugitive.
Meanwhile, Kayce and Cal (Logan Marshall-Green) are both dealing with recent difficulties involving their children. However, the two men respond to their personal struggles in different ways, adding another layer to their relationship and individual character journeys.
Belle (Arielle Kebbel) also faces an important development in her personal life. After deciding to move forward with ending her marriage, she discovers that the process may be more complicated than she initially expected.
The episode will also feature the return of Judd Lormand as Eddie Wilson and Marque Richardson as Assistant U.S. Attorney Patrick Burns. Both actors make their Marshals debuts in Season 2, Episode 7, which airs on November 22.
Before that, the series returns on November 15 following a one-week break. That installment will focus on Mo, played by Mo Brings Plenty, in a special episode inspired by the actor’s family tragedy.

Scarlett Burke’s Career Beyond Marshals
Burke brings experience from both television and film to the Yellowstone spinoff. Her previous screen credits include Ray Donovan, True Blood, Animal Kingdom, Lethal Weapon and Taylor Sheridan’s The Madison. She also appeared in the feature film Magic Mike.
Alongside acting, Burke has developed a career as a country music singer and songwriter. She has written songs with several well-known artists and industry figures, including Miranda Lambert, Jelly Roll, Elle King, Nile Rodgers, Shooter Jennings and Liz Rose.

Her work has also received recognition from the Production Music Association. In 2020, she directed and executive produced Make It Up As We Go, a scripted podcast featuring Miranda Lambert, Billy Bob Thornton and Dennis Quaid.
With Shelby Gaines joining East Camp, Season 2 is introducing another character whose personal history may add new dimensions to Kayce’s world. Her involvement in the equine therapy program also gives her a direct connection to the ranch’s developing storylines, setting the stage for her recurring role in the series.
