Jack's character journey to me has been a fascinating thing to watch. To see him grow from a fiercely stubborn man with a compulsion to fix everything, burdening daddy issues, and a refusal to believe in anything that's beyond the explanation of science to a man who embraces destiny and faith with open arms, who believes in the words of John Locke like a converted believer, and sees the island as something special instead of a place he needs to run away. What do you guys think about his evolution? Do you believe in his growth?
