Another layer is added to the mystery of Booth’s whereabouts and the state of his physical condition when the team learns that FBI Agent Miller (guest star Kim Raver) has not been entirely truthful with the FBI and the Jeffersonian, keeping vital information from them that could lead them to Booth. Meanwhile, the Jeffersonian gets a surprise visitor, FBI digital forensic scientist Dr. Benjamin Metzger (guest star Josh Casaubon), who works with Angela to try to decode the information the team has been able to uncover regarding Booth’s location and the circumstances surrounding his disappearance. Also, Arastoo makes a major decision that affects his and Cam’s personal and professional relationship.
