Wait WHAT?? Madara stays because he know the handsigns of edo release?? Itachi u dumbass, u left the shinobiworld too early

(.. And where did Madara learn the Edo release from anyway? Since Tobirama was the one who created the jutsu he could've been in contact with him and learned the release or something? Bah what am i talking about xD.. In chapter 560 we saw what Madara was thinking about, what he excactly was thinking was: "..This is his doing.. He definetly has something in mind, but what? Things dont't seem to be going as according to plan very well. That someone was able to revive me into this kind of state". After that he asked who the controller of the impure world resuriction was, then Kabuto used Muu, wich was with Madara to say "I am kabuto. His assistent. Since he said he was "his assistent" what he means is Orochimarus assistent.. They must've been in contact with each other before Madara died since he knows Orochimaru.
