If it's someone from the list it's Partridge gotta be  i suspected him after rewatching the pilot episode but dissmised it when he didn't appear again in the first season   when he popped up in the season 2 finale (a red john ep written by bruno heller) my radar went off and in season 5 he showed up in two episodes(on a red john season finale ep written by bruno heller) an all my suspicions were confirmed by just the fact that Partridge is on jane's list   and he's the only one the show hasn't hinted  is red john       everone else is either too obvious or not obvious at allI've got every season on dvd and have watched every episode at least 3 times each the more i think about it the more i'm convinced Red John is more than one person(a cult within Visulize?) and is heavily involved with Visulize (mentored by or working for Bret Stiles) 1-Stiles' knowledge of Red John    2-Red John's accomplices appear cult like  3-Visulize has members in the CBI  4-The smiley face on the barn at the Visulize farm       
Red John has a connection to Jane's carni past  1-there's a reason Red John hasn't killed jane  2-maybe knows or is Jane's Dad or brother in law Danny 3- could be related to someone the Jane's ripped off 4- the knowledge of Jane's happy memory 5- Shaun Barllow seems to know a lot about red john and describes jane's dad as wicked  
 
 it's not one one of the guys on the list   every possible Red John reveal has been a fake out this is just another cock tease another ploy by jane so red john will let his guard down    It's gonna be dissapointing if it is just one of the seven people on the list     it's gonna b more than one person or someone not on the list #1-Janes dad #2-Mashburn #3-Minnelli #4-Christine Frye #5-That blind chick is not blind  lol

But still . . .revealing Red John has been Jane all along would make this the greatest show ever going back and rewatching every ep knowing jane is really red john would b crazy
