When the techs find York's neural implant they wave the doctor back over, speaking quickly and with great interest, asking him questions about what it is and how it got there. York doesn't answer, just asks if it's still active and if they can get it working again. They don't know, but he's agitated and causing a bit of a commotion that may draw the Lady over. He wants to see their equipment to try and scan it himself and they don't want to surrender anything to the stranger. Understandably.
