^That would make a lot of sense, given that the Senju seem to be the rational ones after all...no lineage of hatred and all that.
And now the Hyuugas are left out in the cold...maybe they descend from Rikudou Sennin's disowned third son or something.
I wonder how the First Hokage managed to inflict such lasting wounds on Madara. If after all these years Madara remains broken, it'd have to be something pretty strong, maybe a seal of some sort. Given that Madara didn't die from it and that he's still referring to himself as an empty shell, I guess we could probably say that the Hokage probably used some final curse on him before dying. It could even be that it's not his original body. I mean, what could Hashirama do to prevent Madara from accessing his Mangekyou Sharingan, or even his EMS?
If that's the case, then I wonder where his space-time justu comes from...
