OK on last episode of season 3 many things revealed for me ?!!!
First how Timothy Carter knows things only red john knows and he is not RJ ?? so my guess is Timothy Carter know red john or his relatives
Jane took Gale Bertram to  ((( Pinewood shopping mall >> place where timothy were killed by jane ))) and there was cho and rigsby also ,,, SO NOW
How timothy carter know that place ??? is this a coincidence for him to be there >> NO ,,,, a place who (jane - bertram - cho - rigsby ) only know it ,, Lisbon may know but i am not sure about that!
so my guess is that some one of the 4 people tell timothy to go there and act as to be a red john to play with jane
** bertam could be highly suspect and then cho may be ??????
