Teonna Rainwater has ventured into Texas in 1923, and she's in danger near a familiar location: the 6666 Ranch. Taylor Sheridan has expanded his Yellowstone franchise with two shows so far, but there's more on the way. Aside from telling the story of the Dutton family's lineage at various points, the prohibition-era Western drama is examining the history behind two other major components of the original Yellowstone universe: the Rainwater family and the famous Four Sixes Ranch, the real-world establishment recently purchased by Taylor Sheridan.
