ok been seeing alot of dumb theories lately and i just want to bring this up none of what we saw was a zetsu clone that was the real rin and the real kakashi the reason for kakashi is right before obito arrived he was seeing through kakashis eye and saw rin dying now people are also saying "well right after that zetsu said dont imagine things" well he probly didnt even know that it was possible for the eyes to be connected and mabye thought he was little nuts. Now for rin it was the real rin because when a zetsu clone is attacked like that they usually revert to their normal form right away like when saskura attacked the one pretending to be neji he reverted to normal form now u might say " well when zetsu was posing as kisame he didnt revrt to normal form right away" well i think that zetsu was the real white one so he could revert back when he wanted, another thing is we see rin crying and kakashi crying and rin is bleeding didnt know zetsus bled when they were attacked as well... just thought i should point these things out
