I think that Bruno Heller is kidding with us with this ending of Red John saga, come on he was director of Rome one of the best series ever, he is not so stupid to make so complex story of Red John and not to choose who it is from start instead choose him after 5 seasons,maybe he is doing it to get attention,i think that McAllister is just another puppet of REAL Red John, and that this story of Red John is far from end, in Bruno Heller we trust!
