Red John could be a by product of tiger tiger org. He who created the tiger created the lamb (red John). He may have a grouse against the tiger tiger org and may have some members working for him. This way he knows all the inside info. Alternatively he may be a member of the tiger org.
I think maybe it is the priest from the ''Red Barn'' Episode, I still don't think that any of the 7 is Red John except maybe Bob Kirkland.
I do however think Van pelt is working for Red John , And i did'nt for one min believe that Lorelei was telling the truth on the cd or is in any danger , But maybe is is pregnant for Patrick <<<<<<<Now would'nt THAT be something !!!!! ;)
Patricks own father was one of my suspects but i don't know if he is still alive or not , Just a thought.
