Here is a new theory that entered my mind after watching tonight's episode and the preview for Fire and Brimstone: Haffner says to Jane: "There's a comeuppance heading your way." I believe this is a reference to the Tyger Tyger group.
In the next episode, Jane succeeds in getting all of the Red John suspects gathered together in one room. Jane pulls a gun, and he seems intent on killing whichever one of them is Red John. Lisbon tries to convince him to stop, and as she arrives, the building Jane and the suspects seem to be in explodes. My thoughts on what happened? The Tyger Tyger group is actually AGAINST Red John and they found out that all of the suspects were in that room. So what do they do? Blow the place up of course. Cause we all know Jane's not going to do that. He has a gun in his hands, not a bomb.
Also, aren't the suspects all gathered together a little too early? We still have two RJ episodes after it. Interesting..
