PROBABLE SPOILER!!!!! 

I will give you a link below. It shows the reactions of a dude called Americ while he watches 6x08. He claims that he gets to watch advance views of the Mentalist episodes because he has a youtube channel and recording reviews about the episodes before they air. This time, since the coming episode is of the highest importance, he doesn't provide a review but let's us see his reactions while he watches it.

This is not the worst part. There are comments below that video and someone nicknamed simplythebest286 (who claims to be Americ himself) is telling almost everything which is pretty annoying (if true) and if this is the case, FUCK HIM! And if you don't want to take risks, do not click the link below. Because I wish I hadn't.
