Haffner if RED JOHN !

If there is no death scene, there is no death. He's alive and Jane remembers what really happened. Maybe Jane is ok with stiles pretending to be dead to dodge the FBI and get some free time. No major actor would leave the show without a big scene. Haffner was shown lifting weights, has to be RED John. That is the premise of the RJ Character. Bet he has a big dragon tattoo on his back. Somehow RJ will be from Jane's childhood. Possibly resentful of him moving on. Although I wouldn't be surprised if they kill who they think is RJ, close the case and in the series finale find out the real RJ is either A. Patrick Jane alter ego. B. Theresa Lisbon with a big dragon tattoo on their back/chest
