What the heck just happened, Like all other theories state, I just wasted 5 and a half years of my life and it's this ending we get. What the heck. I believe the real Red John was Timothy Carter. After Season 3, CBS decided to get the Mentalist going longer, Which explains why Bruno said He didn't know who Red John was. They choose a new Red John to keep the show going to get more money, Which is why we got such a crappy ending all because CBS had to get more money and extend the show and make up a phony Red John. I don't exactly hate Bruno Heller now, But if he was on fire and I had water, I'd drink it. Lol guys, Let's see how Bruno fixes this.
