  SPOILERS MAYBe??

I just watched the episode, and I will tell you right now that Bruno Heller deserves a standing ovation. WOW. JUST WOW. He tied up almost every loose end we have brought up on here, and he did it in a way that is smart and well planned, and I firmly believe he knew who RJ would be from the beginning. Can’t give enough credit to that man. DAMN.MASSIVE SPOILERS BELOW…………LAST CHANCE TO STOP………..All I am going to do is confirm a few thing most of you already know, but I will not say who RJ is, because honestly, you dont want me to. The reveal is that good. But I will say that….- the Harker description is pretty accurate
- The Tyger Tyger group has more than one single leader
- the RJ voice explanation is handled brilliantly, along with all the other red herrrings
- my resurrection theory was pretty spot on (remember 5/7 suspects are “dead” so that isnt much of a spoiler)(my own personal spoiler below)- imagine all the suspect are alive…follow the actual clues throughout the series…and you can identify Red John. They didn’t use anything that wasn’t already in the show to tie up the loose ends, so all the info you need is there. I know that is easy to say in hindsight, but it really was right in front of us.
