What about Marcus Pike being the real RJ ? The final could be that he never gets caught:
- "He is mar" can be "He is Marcus"
- he corresponds to the description made by Rosalind
- we still don't know how PJ's suspects list got found by Red John and his team
- MacCallister looks HARLDY shaped enough to lift PJ's chair, earlier in the show while whispering "Tiger, Tiger, burning, burning...".
- I hardly believe Sheriff Mac Callister to be Lorelei's sister rapist
- as the final of the show, we could see him moving to Washington DC with
Teresa, then never be discovered and running away with PJ's cherished workmate. He would win the game.

This Marcus is weird...
