After hearing wind that the Mentalist may be cancelled at any second now, I just want to voice my disagreement with Heller's choice to reveal McCalister in Season 8 of a series.
At least do it at a season finale, so that way the network will have to renew it to find out Jane's life after the reveal. 
I am constantly praying that that was just another whole layer of the Red John story, because,let's face it, despite people claiming they were satisfied, they won't be unless it is Jane himself, Lisbon, Cho, Rigsby, maybe Van Pelt or a character that was killed off eg. O'Laughlin or Bosco. Or of course, CBI Ron. Nobody wants a man who had been discarded from the whole series for 5 seasons. Grrr... Bruno Heller I am pleading that one of the next few episodes proves me wrong. That Richard Haibach twist was such an anticlimax, and you killed 2 good cast members for it?! Please don't let my favourite show die. Not like this.
