well this is simple and easy theory for you all xD.
after reading 373, i have been re-thinking about Pain's bodies. At first, i thought
those bodies were the strongest ninjas that pain/nagato have defeated; but
coming to this chapter, i am thinking that those 6 bodies could be... the
body of sage of the six paths.(maybe not, since the first body is most likely
to be Yahiko's). but since his eyes AREN't changing at all, I think my theory
could possibly be true.
i also think that Pain & six sages of the path can be related to
the statue that pain was sitting on at the end of chapter 325.
only b/c the statue had the same eye as pain .. >_>;;
