Who is George Stark Really? [Thread may contain Spoilers]

[Pole]

Question (Theory): Was George Stark Thad Beaumont's undeveloped twin that was removed from Thad's brain; not just an entity created from his alter ego's pen name? I can't exactly remember what happened to the undeveloped twin that was excised (I believe it was disposed of as medical waste), but I'm sure it did not end up in Thad's local cemetary, where the People photo shoot was done. But this makes more sense to me, even from a supernatural standpoint. Otherwise, what was the point of the whole story on Thad's background, except to possibly explain his semiconscious, possibly psychic, connection with George Stark? All thoughts are appreciated.

George Stark is One High Toned Son Of A Bitch. What a Character. A true exercise in a man who knows how to get things done, regardless of how you feel about his moral turpitude.

...I don't think George was an actual "outgrowth" of the under-evolved fetal tissue that was removed from Thad's brain...but somehow he became a construct from the remaining cells that were not excised-that "connection" allowed thought to become "flesh"....IMO...

I always thought he was Thad's unborn brother's spirit. Materialized into a human being somehow (well, if a car can be posessed...), wanting revenge because Thad "stole" his life, and he wants it back.

I always thought George was nothing to do with the unmaterialized twin That was your basic red herring. I always saw George as Thad's Dark Side manifested.
