I did not want it to be McAllister, and I'm not necessarily convinced from the promo shots that he is 100% Red John...but Reede Smith said that Red John is a member of Tyger Tyger right? So that means that he MUST have that tattoo, which leaves us with the three suspects Bertram, Smith, and McAllister. Smith, I'm sure is not Red John...so that leaves Bertram and McAllister..it's one of the two. Unless Red John does not have the Tyger Tyger tattoo of course......I hope nobody has brought this up yet, or else sorry =P. Can't wait for the reveal though!
