The three dots is a typical symbol of someone who has been in jail,  like the tattoo of tears represent the people who killed a murderer . i dont think it has any supernatural meaning , on the contrary, it reveals that red john still be a human being . All these things will help to have an even brighter END.
Patrick has had another whiteboard in his head that we can not see and also we know things that PJ doesnt  know ( tyger tyger .. etc) . My question is always the same ;
What do we know about whiteboard that doesnt show Patrick ? We know nothing , but we know what he doesnt know and i still think that he goes a step ahead. And that's why we waste the time thinking about the physical , which side has RJ the hairline and stuff like that....

What would you say is the most suspicious to Patrick ? PJ shows a special interest in McCallister and  Partrigde , actually was very insistent and defiant asking them anything. PJ doesnt show the same with Haffner , or Bertram or  even with Smith (although I admit that was my favorite .) Why? because he knows that RJ has nothing to do with VISUALIZE , nowadays , but he knows that it is important that Brett must to be close because it is the only one who can help an authentic way ( this means that Haffner 's out ) .
In the last episode a private detective put a hide micro under Cho´s desk??? WTF??  If Haffner spends the day at the CBI is clear that he might have installed the same ... This means that RJ acts on its own and not through TYGER TYGER even, to spy some people, and that leaves us with few suspects. Bertram , Mc Callister and yet it may be my "  old -favorite " Smith

PD , I remind you that Partridge is dead ( someone still telling he will appear somehow )
