A few episodes ago we saw a blond boy in the jungle, telling Flocke "you know the rules, you cant kill him". Who do you think the boy is? The islands spirit? The Balance? God?
Does he make the rules? Or is he just a messenger? Why is it a teenager boy?
And if it was Sawyer that the boy told Flocke not to kill, then Sawyer is highly potential new Jacob? By this way, would you in confidence say that MIB is the black stone, Jacob ( or the Successor(s) ) is white stone, and the boy is the balance?
