Did you notice an interesting fact about CBI team and Patrick Jane. None of them speak about their mothers...only abusing fathers, it is a the same to Rigsby, Lisbon, Van Pelt, Cho (he was a teenage gangbanger so...) and Patrick. They all come from a damaged background childhood.
Why Patrick in the past retrospectives did not wear a vest? Why now he always wears one?
Why Heller focus so much about mental illness in this show? same to memory and sleep problems to? Why Patrick is in the center of this story, being in the same time a compreensive human being and same time a sociopath? There is something very dark in him, i don´t think for sure he is red john, but i very good candidate...What if Patrick and red john discoverd (whell they are portraited as smart and intuitive) a law enforcement plot, and the list of 7 is all about revealing that plot and nothing about red john? it is possible, but not likely. It is strange but i think Patrick discovered more about red john with the fake list rather than with the suposed "real list".
Well the real red dreagon is Heller :), he was all the power to decide who is red john and what is relation with Patrick, visualize and the Tyger gang.
