We are all a little confused about stuff like "How does Edo Tensei revive you?". Some say it's how you died, other say, it's in your prime. There is a lot of contradiction but since we found out Madara was upgraded by Kabuto, things became clearer.
But what I absolutely dont get is the fact that both Madara and Nagato got ressurrected with Rinnegan. These eyes are transplants (Madara got them from Izuna to create EMS and later Rinnegan. Nagato presumably had Madara's eyes transplanted as well, even though we dont know that yet. But let's just assume it.). So why were they ressurected like that? Because it means that this body part (the eyes, obviously) were brought back twice and they were not even original body parts of either Madara or Nagato. Madara would still make sense if we regard the EMS as a fusion of 2 MS. But Nagato is a plothole.
Just imagine what would have happened if Kabuto had revived Izuna as well. Or if Tobi had died and Kabuto brought him back as well. We would end up with 4 Edos who basically all have the same eyes.
Confusion!
