He is much more than a trained combat medic. There is a psychology component. In that first freeze video when Doctor Diazepam jumped on the stage and shooed all the SS agents away the stage talk went like this:
Dr Diazepam — You're OK. Keep talking. You handle it. We're not going anywhere.
Hillary — OK, here we are, Ah ha ha ha ha ha ha hah.
Dr Diazepam — Keep talking ma'am. Keep talking.
Hillary — OK, we'll keep talking.
As the judge might say he is leading the witness. That is mind control shrink type talk he is doing. Hillary is a super space case freakazoid.
Excellent point about the psychology component—Hillary even repeats what he says to her—to jumpstart her brain.
Black Bart is more than a regular agent.
