'Yellowstone's' Most Infamous Location Just Showed Up in 'Marshals' Episode 2

Yellowstone fans watching the second episode of Marshals Sunday night caught something new viewers almost certainly missed, and it's one of the biggest callbacks to the flagship show yet.

The "Zone of Death" is back.

For those who never watched Yellowstone, the Zone of Death is a stretch of Idaho land within Yellowstone National Park where, due to a quirk in the U.S. Constitution, crimes go unpunished — no jury pool, no law enforcement jurisdiction. On Marshals, Harry, the chief of the Montana U.S. Marshals unit Kayce has joined, describes it plainly: "Local legend has it that it's been a dumping ground for the region's most depraved criminals."

Yellowstone fans know it by a different name: the train station.

The 'Train Station' in 'Yellowstone'

Over five seasons of Yellowstone, the Dutton family used the Zone of Death as their private dumping ground for enemies and inconvenient bodies, referring to it in code as "taking someone to the train station." The most significant use came in the series finale, when Kayce and his sister Beth disposed of their brother Jamie's body there — leaving one of the show's biggest unresolved threads dangling for any spinoff that might follow.

Marshals is now pulling on that thread. In Episode 2, Jamie's mysterious "disappearance" comes up multiple times, with Harry pressing Kayce's partner Pete about what Kayce knows. Fellow agent Andrea questions Kayce directly about his brother's whereabouts. And when Harry asks Kayce whether he's familiar with the Zone of Death — given that his family has been in the region for a century — Kayce says he's never heard of it.

Yellowstone viewers chortled, knowing that's a lie.

What makes the callback even more layered is that Logan Marshall-Green, who plays Pete, had never seen Yellowstone before signing on to Marshals — and deliberately avoided watching it so his character's genuine ignorance of Kayce's past would feel authentic on screen. When Marshall-Green eventually learned what the train station actually meant in Yellowstone lore, he said he was "a little shocked" — but couldn't show it.

How long Kayce can keep his secrets buried is one of the central tensions of the season. Showrunner Spencer Hudnut has already teased that the first season ends "in a propulsive way that paints us into a corner" — and that a Beth Dutton crossover is not off the table.

Marshals airs Sundays on CBS.
