I'll admit it, I absolutely hated Jason's character when he first reappeared. He was whiny, arrogant, and pompous in my mind.
A haunted man who made mistakes and wants to make amends in some ways; though that doesn't mean he believes he was entirely wrong, just that he was too extreme.
I don't know why but Jason reminds me of Snow from A Game of Thrones. A bastard son who is both a part and outside of his family.
