So Madara used Izangi to evade 10 minutes of explosions...I had forgotten about the technique, but I guess he can do it since he has a hoard of sharingans at his disposal.
So Madara got Konan to reveal the burial location through sharingan manipulation? Just like Sasuke used to find the location of Killerbee in their first encounter? Lame but ok.
Nagato (his eyes open in death is pretty creepy) is a Senju descendant, surprise! But not.
Madara was the 1st path, he acquired the 2nd from Hashirama, and Nagato is the 3rd-which number would Naruto be?
