i re-watch again season 3 ep 23 .... when jane told bertram about the meeting at mall he called someone after jane leave ... maybe the fake red john ... he know about jane s plan and he played jane s game because he thinks he will have hands clean :) .... red john always was with two steps in front of jane ... now think .... how fake red john knows jane was there? because only bertram knows O Laughtin didn t know ... so my guess is Bertram is the real Red John ... but he played their game ...
