mentalistfan123 - I dont think that Bartram could be Red Jhon... At the end of the 1 ep from sea. 6- we can see R.J.'s  hands. They are too skiny... But!!! If we look carefouly at the 7 members list only Ray Haffner and Brett Partridge has ,, that kind of skiny hands,, But Brett is dead... 

Also another theory that I was thinking is what if Red Jhon is not  just one pers.? What if the ,,real,, Red Jhon is Ray and also Bartram? Or Ray and Bob... ( Bob was that pers. who brokes in James room)
