Re: Yamato is the one who knows everything
i was hoping it is Izuna Uchiha: Madaras younger brother. It makes sense Oro would know where he is buried, and also how to revive him. also, of all people, he would know everything about madara; including his weaknesses - and would know why madara may have ordered Obito (thats what i think) to wipe out the Uchiha clan. as well as the truth about the clans history. Would make sense he told them everything he knows, as it would add up he be resentful of Madara for stealing his eyes. Considering he is also blind, it would make sense he might actually be very very wise.
Plus, would be cool if Sasuke actually had some kind of 'Uchiha' fall back plan, considering he is the one who revived Oro to help him find 'The One Who Knows everything'.
So i think it could possibly be Izuna: The Blind Uchiha: The One Who Knows Everything.
would be epic.
If it is Yamato, or even one of the village elders, i will find that very anti climatic.
