I think that the sick girl who Jane and his father have
tricked was Van Pelt`s sister. I mean, Jane remembering her in the same episode
when Van Pelt remembered her sister who “ended up for her” isn`t a coincidence.
So if this would be true, Van Pelt has been whatching Jane for a long time.
Interesting fact:
Van Pelt believes in the existence
of psychics. Red John doesn`t. My theory is that she is working for RJ; you
know that Red John said to Jane “if you were a real psychic, and not a fraud…”,
so this could be Van Pelt`s words “if you were a real psychic you would have
saved my sister”.
