Stuart (guest star Jeffrey Pierce) tasks Nate (guest star James Pizzinato "Alcatraz") with deciphering the copy of Kellian's manuscript but Cameron (guest star Eric Lange) remains skeptical that Nate can uncover the answers about the Moon Hill parents. Nate asks Allegra (guest star Sheila Vand, "Argo") to get a message to Jeff if she makes it out alive. Nate reveals to Stuart that 32 followers disappeared from Moon Hill, and gives Stuart a phone number that he found repeated in the manuscript's code. Jeff and Skye remain in hiding from the True Believers, now that Stuart knows that they know his true identity. Meanwhile, on the inside show, Billy (Robert Knepper) has tracked Henry (guest star Frank Cassini), the killer of Kelly (Alona Tal) and Meadow's (guest star Shauna Johannesen) parents, and holds him captive. Kelly begins to unravel emotionally as she wrestles with unresolved feeling about her parents' murders.
