One of Yellowstone‘s most infamous storylines was introduced in the second episode of Marshals on CBS. Now, fans of the Taylor Sheridan series have a dark theory about what bringing the “train station” back could mean for the spinoff’s future. (Warning: Spoilers for Marshals Season 1 Episode 2 ahead!)

The Marshals series premiere on March 1 revealed why Kayce Dutton (Luke Grimes) needs a new start with his son, Tate (Brecken Merrill). In a tragic turn of events, Kayce’s wife, Monica (Kelsey Asbille), died of cancer in the time between the Yellowstone series finale and the Marshals series premiere. Yellowstone killed off Kayce’s brother, Jamie (Wes Bentley), in the final season, but very few people in the show’s universe know that Jamie is dead and dumped at the train station — the “no man’s land” off of a cliff in Wyoming that the Duttons used as a secret place to toss the bodies of their dead enemies.
