I watched the episode on the link I got here. I'm certain it's fake. It was far too cheesy to be a legitimate reveal.
Best moment in the fake: The mighty Red John lying on the grass, crawling, grunting etc - and WHO does he call for help... '911'.
Really? The man who had moments before spent time grandstanding and telling Patrick in the chapel how powerful he is, how many people he has working for him, how he controls the 'lives' of thousands - and he calls '911' for help when his shit get's real?
Sorry - that was a laugh out loud moment.
If we're expecting too much from 'Red John' Mr Heller - it's because YOU have given us this expectation. I'm expecting you to deliver (smiley face)
