Ive really enjoyed reading many theories here during this season, and like a few others, I felt like I had to make a comment before next weeks episode.
I am sooooo looking forward to a great episode, and I am SURE, POSITIVE, DEFINITE, that Red John, is a person that no-one has suspected. I dont mean a random, unseen character, but rather a fantastic peice of writing from the team.
Surely someone from Lisbons team has to be dirty, Tyger Tyger, Red John accompice or otherwise.
I noticed the scene from the promo for 6x08 in the church, looks like it happens first in the episode, an extention of 6x07. Jane pulls out his gun from under a pew (the gun has gaffa tape on it like its been taped to something), Red John escapes - injured, and the chase is on, again!
