I've read many theories on this site, most of them are well-thought, but man some of them are utterly pathetic. TWIN BROTHER MICHAEL KIRKLAND? SERIOUSLY PEOPLE? What on earth are you guys smoking? Come on guys, it's not rocket science, it's basic logic. An irrelevant character that was introduced very late on the show is going to be the big bad Red John? I'm not even sure we can call him a "character".... Come back to your senses, have a cup of tea, take a shower, relax on your sofa/chair or whatever and think for one second before writing your theories. Imagination is one hell of a weapon, but without critical thinking, you won't be able to use it wisely.
