Dutton Ranch's Surprise Mystery Villain Reveal Confirms Beth & Rip's Boss Is A Liar refers to new revelations in season 1, episode 7 of the Yellowstone prequel spinoff. The episode, “Den Of Sin,” uses flashbacks set around the 10-Petals Ranch’s 190th anniversary celebrations in Rio Paloma to detail Beulah Jackson’s origin. In 1981, Beulah’s night out in Fort Worth, Texas turns tragic after she meets Luke, a mechanic at Six Flags, who rapes her. Later, Beulah discovers she is pregnant and kills Luke at his trailer. The story also expands on the mystery villain through young Mariano Reyes, including a decades-spanning connection to Beulah and secrets tied to her unseen father and the ranch’s leadership, which may explain present-day power dynamics.
