What do you think about Handshake induction it's a hypnosis technique.Just search on the internet,is very interesting. Maybe RJ hypnotized PJ when they shook hands and RJ is not on the PJ list,because he don't remember when they shook hands or is a member of the CBI that use hypnosis to misguide Jane(1.is possible to shook hands more that once and 2. is possible to use hypnosis on jane when they are working on a case).
"If you don't want your subject to know what you are doing, you simply distract their attention, usually by some appropriate remark, and casually terminate. Sometimes they remark, "What did you say? I got absentminded there for a moment and wasn't paying attention to anything." This is slightly distressing to the subjects and indicative of the fact that their attention was so focused and fixated on the peculiar hand stimuli that they were momentarily entranced so they did not hear what was said."it's on wiki.
I think the "shooke hand" it's more that a simple shooke hand ori my theory is to complicated.
