What's your best guess on the nature of Locke right now?

• He's the same as he was, and simply the first person to be revived as his old self on the Island.

• He's a "fascimile" of the old John, with the Island pulling a few of his strings at key moments.

• He's the Pinocchio to the Island's Geppetto.

• Jacob got into Locke's body after the crash and is helping John fulfill his role.

• He's no different than any of the other "dead" people we've seen interact with the Losties.

• None of the above. (Explain your theory in the comments below!)
