Check out John Locke on Lostpedia. we all agree that the "new" john Locke is not the same old one.but who is the new one,here is the revelation: The new one is a mix of john and christian shephard. here is why? first of all,do you remember when jack got his father's pair of shoes from his grandpa and then put them on Locke's lifeless feet in "316".That was a clear declaration that john will be in christian 's shoes when returns back to the island. I think that is more than enough to prove that christian is the new john Locke or vice versa. How is that?
