I'm thinking that the scene in the preview for the next episode is obviously meant to be misleading...
My guess would be that Kirkland has Jane and wants to get the names from him, but somebody interferes, and then Red John (or one of his associates) is going to be the one torturing Kirkland instead...
So the question is:  What is the final clue that Patrick is going to get in this episode?
Did Patrick set up Kirkland to get the final clue?
Somebody else mentioned that Patrick would know that if he was in danger, that Red John might save him again...

Anyway, just looking forward to tomorrow night!
