Bones S2 E11: Judas on a Pole
Zack defends his dissertation to obtain his doctorate and asks help from a colleague. Meanwhile, Booth and Brennan are called to the scene where a man's body was found gutted, burned and hung like a scarecrow on the roof of a hotel that housed Federal witnesses. Booth determines the victim was a snitch working in an organized crime syndicate. Brennan's brother, Russ, informs her of a phone call he received from their father, warning him that they are both in danger. Soon after, a priest contacts Brennan telling her that her father insists that she and Booth drop their case. They determine that the body found was actually an ex-FBI agent, who was tracking Russ to kill him - hence, giving reason to Brennan's father's warnings.
