Leaked episode: Real Or Not . . .
Would have have much rather the writers used this theorist's/spoiler's outline for the finale. Would have at least gotten most of the nagging questions answered.
Follow the evidence of this "leaked" episode and I think you wind up with Reede Smith, aka Roy Tagliaferro I, as Red John Killer, with Michael Kirkland (or MAYBE Brett Partridge) as Roy 2 and his main accomplice.
This Sheriff Mac as Red John comes out of nowhere with NO backstory whatsoever.
