This chapter explains a lot. It explains the goofy, carefree Tobi that we know was either inspired by the Spiral Zetsu, or actually the Spiral Zetsu himself. Also, we see where Obito got his long hair from. This ties it together with his appearance during the Bloody Mist, where supposedly Madara was controlling the Mizukage. Next week will be a good chapter when we finally are shown the reason why Obito became a villain!!!
My only question is: Where is Black Zetsu and why is he so different than the normal White Zetsu??
