Hodgins admitted to Angela that he felt like the Gravedigger still had him locked up. The stress of the case took its toll on the team. That’s why Angela could have altered the voice why Booth could assume that she was the only one who made a purchase from the mall on the day the boy was abducted and why she made that call to Utah instead of the police officer from Salt Lake City on the night she was arrested why Brennan (so traumatized she’s seeing an FBI psychologist) could say the attacker was the height and weight of Taffet and why Hodgins and Cam could say that the dust mite found in the boy’s teeth contained Taffet’s DNA and destroy the sample during the test so the defense’s expert couldn’t run one. They wanted a scapegoat, and they’d decided it was her.

That’s all the opening Taffet needed to start arguing that everyone on the Jeffersonian staff serving as experts was biased. When Brennan felt threatened, she said in addition to being the best at her job in the world, having been buried alive made her uniquely qualified to explain what this child went through. Taffet had gone after Angela’s credentials on the stand when she finally figured out how to decode the creepy ransom voice and revealed it was Taffet’s. Perhaps Booth should have reminded Brennan not to mention that she’d also been buried alive.
