Visible crew/equipment: When Bones starts the interrogation with Rulz, you can see a shadow moves over Rulz' lower body despite no one moving. (00:32:55)
Answer: Answering my own question here but, having contacted various people involved in the production of Bones including Kathy Reichs, Hart Hanson, Eric Milligan, and Deirdre Lovegood who portrayed Taffet onscreen I finally have the answer. No-one know how she did it due to her constantly working alone. And she never revealed this information before her death.
