I just read "along came a spider" by James Patterson at Last week about a killer who has a split personality. That made me think maybe PJ has a split personality as Red John. Pj knows a lot about little, insignificant details of red john crime scenes, maybe it's his unconscious brain telling him, a common theme with split personalities. The rj personality may be deliberately trying to set up situations for pj to lead him down a false road. Pj often talks about rj like he knows him like the back of his hand even though he had not met him face to face, he often talks about rj like he is himself!
