OMG what if Orochimaru goes over to the injured kages and kills them.. putting them outta their misery..
and what if he uses Karin / Suigetsu as sacrifices.. to Edo Tensei two of the injured Kages...
Since he knows where Tobi's lab is (because of Kabuto experiences)
Then he can use more Zetsu bodies as sacrifices for the other Kages to become Edo's.
Then he returns to the battlefield pretending to be friendly and maybe he even uses Karin's body since she is Uzumaki..
idk
forget the red part
Honestly Orochimaru might get Karin to heal Tsunade...
i'll elaborate later on Orochimaru's plan , but Its a big one sorry im to lazy right now...
