I'm curious to see who actually still thinks Red John is one of the 5.
Up until now I was quite certain Bruno Heller wouldn't lie to us about it but after the last episode I can't see any of them as Red John..None of them seem fascinating or brilliant like this 'great' serial killer who has been killing for so many years..Even Bret Stiles is dying and he seemed quite insane in this episode. (not in a good way)

GREEN:  Red John is NOT one of the 5.
RED     :  Red John is one of the 5.
