As far as who Red John is, personally I dont think its any of Jane's
suspects. However I believe without a doubt that Van Pelt is working for
Red John, we are getting far too close to the Red John reveal and the
side story continues to be her relationship with Rigsby which honestly
makes no sense due to the fact that there they are not moving the story
along at all.
We know very little about Grace's past but the
little we do know is that she had a bad childhood, as Red John did with
Kirkland's brother and so many others he probably helped her and now has
her on the inside. The fact that she got married recently has firmly
established in my mind that she is the mole inside CBI otherwise the
producers wouldnt have written that in, it is all setting up the
audience to feel betrayed because they are pushing Van Pelt and
Rigsby's relationship.
She though is not Red John I've heard
all the theories about her Red Hair and the fact that the literal
meaning of John means GRACE and mercy but I dont buy it shes too weak of
a character to be the serial killer
