I think I've finally solved it! The creators/writers have let their children make the latest episodes of the shows! Now the biggest truth is revealed!!!

However, I belive that Red John will help Patrick Jane to crush the Tyger, Tyger Corporation, and then they'll become best friends and walk hand in hand on the beach during sunset and live happily ever after.

Or perhaps Patrick Jane will kill Red John and Kirkland's twin bro will take after him and the show will continue in a even more twisted way.
