Who would you call Red John? The killer, or the master brain? If your RJ is the killer, then I believe that we will not wait too long to have him in hand. But if you refer to the master brain behind all this puzzle as Red John, then we will have to wait till the end of the show. Because I still believe that there is one killer and one instigator. They will first give us the killer and we will realize that it's not over yet and there's a bigger picture. Then shall come the real deal.
