Yea I'm starting to think it's going to be jane as red john. To add to the previous theory about the split personalities, Do you remember the one time " red john" has in the chair and says supposedly roll tide, the poem and that stuff? Well how do we know for sure that scene is factual when patrick tries to wiggle out of the chair just before that and hits his head off the ground? Watch that scene. And let me know what you think
