Theories of RJ_has_killed_me (2)

It seems that everybody will be disappointed, whoever Red John is.
The fact is during the 5 past season, RJ has always been shown as the most clever, the most skillful, an uncatchable person almost divine always ahead everyone even Patrick Jane.
But, in the season 6, he appears to be "just" a serial-killer, he is beginning  to panic and make some (a lot) mistakes, he does not predict everything anymore.
With a face on his name, he appears to be vulnerable.

As everyone I always hope for a big twist, but in the same time, hurry to discover the truth....

A lot of people have said that Kirkland will torture PJ and I will cut his fingers but look closely at his shirt... Patrick Jane seems to wear a "one color" shirt under his suit unlike the man on the last scene, who wear a checked shirt.
We can also see Kirkland's shirt on the preview, and I see some check on his shirt (but i'm not sure...) : rather than PJ tortured by Kirkland, It could be Kirkland who will be tortured by Red John in this episode.
