I'm not actually annoyed by this episode, I find it interesting as, to me, its setting up for The Mentalist after Red John is killed.
Now I think it would be quite obvious to everyone that the three with the tattoos are not RJ and are part of the Tyger Tyger group. Nobody on the show would have figured this out about the group if it wasn't for this reveal. Also it is plausible that one of them hired and killed the PI as 1. RJ would never hire someone so slack and 2. We know that the Tyger Tyger group has their eye on Janen and the CBI Team. This will clearly be brought up again and be the new storyline after RJ.
We also learn that Stiles has some sort of cancer and is going to die soon, so that leaves Haffner.
He fits every description ever given to us and is the ideal character to pull it off.
It just makes sense that when Stiles dies and Haffner gets caught as RJ, that will be the end of Visualize as there is no more prominent characters left who are members. 
From then on the focus will definitely switch to the Tyger Tyger group.
