Even though am not sasuke's fun, i think he deserve some credit at some points.I mean, who ever thought that sasuke would ever turn on orochimaru, and that, that was his plan from the start, to get stronger until he can take him down. Sasuke is one of...no he is a genius of his time,very smart compared to even shikamaru.Guys, think about it, do you think sasuke doesn't know what is going on?....i think even though he has never seen the real madara, he somehow knows tobi is not him.I think he is just powering up to show his true feelings.what do you think?
