Re: Naruto Manga Chapter 599 Discussion and 600 Predictions
Timeline Plothole Theory:
The other dimension is independent of the real world time. Obito trained, study and acquire all things(medical expertise, hokage level skills, knowledge of everything) he has now, while in the other dimension. So he can spend years in the other dimension at the same time fight an enemy in real time.
Events after the third shinobi war is basically plausible, assuming Obito unlock Mangekyou before those events happen.
Tobi "claiming" he give Nagato the Rinnegan, which Nagato acquired after the second ninja war, could be misinterpreted.
He might trained Nagato with the rinnegan after the third ninja war, not knowing Nagato unlock it years ago after the second shinobi war, and claimed Nagato owe his rinnegan to him.
I'm still on the "Izuna is Tobi" bandwagon as of now, but as I was writing this reply I can't help to think it's plausible.
Unless someone can help me find evidence of Tobi existence before third shinobi war, the other dimension freezing real the world time could cover all the loopholes.
