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.
