Tommy Volker... I just watched the latest episode "If it bleeds, it leads" and it was left open ended with Volker as a powerful man, suspected to have been responsible for the massacre of a village, convincing the news anchor to tamper with the breaks in the car of the last victim (which you have to be pretty smart and conniving to convince someone to take out another persons breaks as a "dare"), and then finally killing his assistant for giving up information then trying to make it look like a suicide. And just when Lisbon told him he wasn't going to get away with it, he responded with "you have no idea what's going on" then told her to "enjoy her job while she still has it." Of course she then gets payed a visit from a guy from homeland security telling her to back off, and as we all know Red John is very powerful, rich, and very connected with high up officials... and then this homeland security guy knows Jane without Jane knowing him... This all just seems like who we know RJ to be.
