Our killer is a lone fisherman.
He has been alone from very young age most likely due to alcoholism in family.
Walking through the rough life of young age he got in touch with Visualize.
Understood himself better, especially his unique skills of understanding the tormented.
Ever since he have seen himself highly moral person. In some sense loathing the weak, the ones who can't carry themselves.
He has helped many to find themselves, though he has understood his own duplicity and the dark side as well.
He has manipulated people to see him as a saviour kind of, though inside he has weighted people whether they are able to stand or their own feet
or they are easy to lead and manipulate.
Ever since our fisherman got to know PJ he has been jealous about him and curious. He has seen him similar to him though the light side of him.
"There can't be light without darkness"
This has drawn and increased his want to be closer and closer PJ.
Our fisherman from light side is all about elegance of beautiful music, poetry and similar. As said, he sees himself highly moral.
On his dark side he is manipulative and for some reason kills women. Something related to childhood and mother?
He has utilized his skills in several places where similar people; people have suffered in their youth some kind of abuse andlived in
various unhappy places.
He have used and killed many people he helped and saw them to fall back be victims of their own pasts; alcohol, abuse and what not.
The life of this highly skilled manipulator consist of
Beauty, elegance of classical music and poetry
Manipulating smaller or bigger fish is his cup of tea
Having difficulty to find women worthy
As PJ have said, a sociopath, able making a crowd to love him like Timothy Carter, who intiated a look for a girl who he had kidnapped
There is only one person left between PJ and RJ, Teresa, the woman with past of Alcoholic father who stands her own ground proudly
and with high morals. He respects Teresa.
As I see it end of season 3 was a masterpiece and season 5 was full of indications of our killer.
Too bad Lorelai was too fast to shoot the only person who would have been easily indicate the killer, and Kirkland provided
a finishing touch for this person on his personal road to Vendetta.
You find your subject. I stick to mine. (He is one of the Seven, don't like to anchor you.)
