Alright ladies and gentlemen i just saw season 6 episode 8 red john spoiler alert!!!!!!
Red john is michael kirkland yes i was as shocked as you were they do tell the story how patrick and michael shook hands at the carnival patrick and his father conned michaels father and mother which drove them to drinking michael met stiles and he took him into visualize and michael found out it was a cult more than a self help place so he asks stiles why not kill people and make money and do cover ups help each other out stiles of course says no he does not condone killing so michael told stiles i will make my own organization hence the blake association thats how stiles knows red joh aka michael. Michael goes onto tell patrick that if you remember what lorlie said to you i will start killing again and often until you catch me or i catch you, michael said you had your chance and the fbi taking over was the check mate you lost. The last thing he tells patrick is the reason why he did not like con men is because what happened to his parents he did not know jane was that con man until he killed his wife and daughter. Other questions are asked and answered i do not want to spoil that much but enjoy the episode it will leave you at the edge of your seat.
