xdThis is a really crazy theory. What if oro kidnapped nawai and was in league with an uchiha guy(tobi). Changed Nawaki face into that of obito, did someind of implant on him to make him look like a normal uchia. Sent him on team minato. "Obito" died, and the Tobi gained "Obito" eyes.Also, apparently, Nawai was so badly damaged that nobody could recognize him!!xd
