Hi everyone.
I think Heller is messing with us. It's quite simple:
We all know from Rosalind that RJ is under 6 feet tall.
We also have Jane's feedback:
"Red John thinks of himself as a showman; an artist. He has a strong sense of theater ... the first thing that anyone sees is the face on the wall. You see the face first and you know. You know what's happened and you feel dread. Then, and only then do you see the body of the victim. Always in that order."
Another clue was in a radio that interview Heller: "Red John is really just a personification of death, I mean it's that simple. Patrick Jane is very much alive and is very much about being alive in the face of death. And Red John is the fate that awaits us all in the end."

I mean... 'Personification of death'? Who's better than a forensic????
And last: the first Partridge's line on the show was: 'Red John enters here...'
Introducing himself with all strong sense of theater as Jane said.
I trully believe Brett isn't death. That's why his body wasn't investigated or showed up.
Let's think: Brett is a primary suspect on Jane's list...
Why the hell Jane never search for the body, or for evidence?
I mean... They told Jane 'Partridge is dead' and that's it?
Our clever Patrick would just sit on the bench and watch the others without any confirmation?
LoL not here.
That's why Heller said that it would be disappointing..
... Just because we all would figure it out easily.
Let me know what y'all think.
