I just hope that atleast Reede Smith is not Red John. He does not fit any criteria and the guy who was in Harker's home was thin, even his fingers were thin. Still in the ending, if they portray Reede Smith as Red John, then this will be the worst series ever on TV. All the clues thrown at us were fake. I think it might be Bertram. Remember Red John told that he found out when his good friend in the FBI found out. Both Smith and Bertram are in Tiger Tiger group. And looking at how things might turn out, Bertram might be revealed as Red John, so in a sense all the clues still stick together and yet the fans will be disappointed. I don't see any reason why Reede Smith would be Red John. He wasn't there from the beginning. Only Mcallister was. So the entire logic has been thrown out of the window by Bruno Heller. The reason why nobody is able to predict who Red John is exactly is because everyone is trying to use logic whereas Heller does not have one logical theory. So whatever you do, in the end I just hope that it is not Reede Smith.
