Okay -- so we've all got Mentalist blue balls...

Because it seems that even those willing to accept that McAllister was Red John are NOT satisfied...

That should tell us A LOT right there.  Would Heller really leave SCORES of fans with Red John interruptus?  I just don't buy it.  It's apart of the puzzle to think the devil doesn't exist anymore.

And though Heller seems to be running through all the colors of the rainbow for his show titles now, it's really only fitting that the show would actually end on RED.  I think it will.
