I know this is going to sound rather unlikely but, don't you think that this entire RJ's episode could be a fake? There are a lot of questions waiting for answers and this still is the begining of the season! 
I don´t know, maybe I'm just dissapointed with the end, what do you say?

Look at Heller's interview to Hollywood Reporter:

On whether Red John's disciplines will take actionHeller: Never say never, but I would say the audience and the story demands that we step away from that trope for a while. The trouble with these stories where you're playing tricks on the audience with "Who is it?" mysteries is that you can get way too mysterious. And there were a lot of people who said all the way along that Patrick Jane was Red John. When you've got that kind of elaborate thinking out there, it's dangerous to come back to stories unless you're coming back to that story with full force, because people will start thinking "Red John is not dead!" Red John is dead.

So I guess this is it guys.

SO many unanswered questions... 

Christina Frye
Visualize in general
Roy Tagliafero
and many, many others...

But who is the hell was the random lady with the knife in the church who decides to attack Jane?

Stop with all the hatred!

Red John enjoys bragging about his crimes and everything, and Patrick knows this, that's why he didn't want to talk a lot, because that would give RJ the confirmation or admiration.

It was long enough and personal enough for me. Sheriff is the perfect RJ. I loved every minute of the hunt!
