Wonder if the person who posted this spoiler http://www.whoisredjohn.com/See-a-theory-Red-John/13389 under Throey 13389 saw a different leaked episode. Because there are too many differences in his very detailed "spoiler" to have been from this episode, especially his/her allusions to Visualize and Roy Tagliaferro.
Makes me think the temporarily available "leaked" episode is a big prank by the CBS.
