If Red John is Reede Smith, I'm never going to watch anything by Bruno Heller again!.
It would be an absolutely ridiculous, pathetic, rubbish ending to the Red John storyline!
This random stranger only appeared first in season 5! Even us, fans, have much better imagination than this! We could have written a much better, exciting ending if that loser is really Red John!! I'm going to be furious!

Sorry for my outburst..:)
