Bones S4 E13: The Hero in the Hold
Hodgins has still not fully recovered from being buried alive with Brennan. He may even be partially to blame for Booth’s kidnapping. Turns out Booth was tasered, knocked out and stuffed in a toy-like yellow submarine. When he gets out of the tiny submarine, Booth finds himself face to face with someone from his military past. The team works on locating Booth and finding who is behind the kidnapping, but the phone message the Grave Digger left states they may not alert the authorities, or the Grave Digger might hurt Booth. We learn why Booth’s son is named Parker. Brennan, Hodgins and Thomas Vega, from episode 2.09, face Judge Dix Williams and AUSA Heather Taffet, also from episode 2.09, and learn that evidence in the Grave Digger’s case has gone missing. The three of them are suspected of taking the evidence. Hodgins is revealed to be obsessed by the Grave Digger and Vega is writing a book on the subject. Agent Perotta and Jared also appear.
