Y: Marshals Trailer Sparks Panic as Monica Vanishes From Story

The new trailer for Y: Marshals, the highly anticipated Yellowstone spinoff, has ignited major fan speculation after Monica Dutton was noticeably absent. Released on November 24, the first look highlights Kayce Dutton, Tate Dutton, and Thomas Rainwater — but no Monica. A brief mourning scene with Kayce standing over a grave has only intensified concerns. Y: Marshals premieres March 1 on CBS and will follow Kayce’s new path as a U.S. Marshal. The mysterious omission has become the biggest storyline ahead of the series debut.

The Y: Marshals trailer reveals the updated Dutton family situation following the events of Yellowstone. Kayce Dutton, played by Luke Grimes, is seen operating from East Camp — now owned by Thomas Rainwater after Kayce sold the land during the series finale. The trailer confirms that Tate Dutton (Brecken Merrill), Rainwater (Gil Birmingham), and Mo (Mo Brings Plenty) return in the new show.
However, Monica Dutton (Kelsey Asbille) is never shown.

The trailer includes Kayce wearing his wedding ring but also mourning at a grave while discussing family losses in a voiceover. Fans are now questioning whether the series will reveal a major off-screen tragedy involving Monica.

Quotes & Reactions

Showrunner Spencer Hudnut described Kayce’s new arc as “a beginning rather than a continuation,” echoing fan concerns about his emotional turmoil. Rainwater’s chilling trailer line — “You’re not a killer, Kayce. You’re a protector.” — has fueled speculation about what Kayce is protecting his family from.
Fans online reacted instantly:

• “If Monica’s dead, I’m done.”

• “Kayce at a grave? Don’t play with us, CBS.”

• “We see Tate, Rainwater, Mo… but not Monica. Something’s wrong.”

Luke Grimes told People that “familiar faces” would appear in the series — but has not confirmed Monica’s return.

What It Means for the Franchise

The potential absence of Monica dramatically shifts the stakes of Y: Marshals. Her character connects Kayce and Tate directly to the Broken Rock Reservation, a major narrative force in Yellowstone. Removing her from the storyline would change Kayce’s motivations, family conflicts, and cultural ties.
The trailer’s heavy focus on violence, duty, and a new team of Marshals suggests a darker tone than Yellowstone, with Kayce’s emotional burden playing a central role.

Release, Announcements & Expectations

Y: Marshals premieres Sunday, March 1 at 8/7c on CBS.
The network has not confirmed whether Monica appears in the series, and her absence from the official casting announcement raises questions. A second trailer is expected in late December or early January, where CBS may clarify her role.
Fans will also be watching for appearances from Beth, Rip, or other Yellowstone characters.
