Jeff (Matt Davis) receives news that one of Nate's friends might be planning something at an upcoming "Cult" fan costume party, so Jeff and Skye (Jessica Lucas) attend the party dressed as Billy and Kelly. At the party, Skye's drink is spiked with a hallucinogenic drug similar to a drug used on the television show "Cult." Sakelik (guest star Aisha Hinds "Weeds," "Hawthorne") warns Jeff that he might be in over his head. Also, at the party, Roger (Robert Knepper) meets mysterious stranger named Stuart (guest star Jeffrey Pierce). Meanwhile, on the television show, Kelly (Alona Tal) marries Billy (Robert Knepper) in a flashback scene.
