To me none of the suspects makes sense as Red John. From the five suspects, the most likely one would have to be Haffner or even Mcallister. But i don't think that any of those two would make a great ending. We waited 6 years for this moment, everything leading to this, and then they make this list which i think it wasn't a good idea. The perfect Red John would be Brett Partridge, and i still don't understand why they killed him in the first episode, unless it's part of a twist already discussed many times.I think Heller trapped himself with this list, unless there is something more i don't see how he could surprise anyone. Anyway, i hope he does do something more, a big twist to end this storyline.
