They still haven't explained to us, how did Madara escape the edo tensei release. I'm guessing that he used his own rinnegan for his own rinne rebirth, so now I guess he has all the powers of Nagato under his control, but if he gave nagato the rinnegan in the first place, how does Obito still have one if it belongs to Madara? I also noticed that Madara already has both his rinnegan, so if Obitos' rinnegan came from Nagato and his came from Madara: doesn't that mean that Madara should have a missing rinnegan? Also he can switch between both sharingan and rinnegan so does that means that Nagato also had both since he eyes came from Madara? Or was that just a lie Obito told about Nagato receiving the rinnegan from Madara???
