So in light of the recent chapter (Slowpoke I choose you!) we saw how Obito got his Mangekyo Sharingan at the age of what, 14? Also, he apparently started bleeding, a lot mind you, after using Kamui heavily.
My questions are: how much of his eyesight remains, and why doesn't he bleed from his eyes anymore? Does Senju DNA magically keep one from losing one's eyesight? (I bet that'll be the explanation)
Also, what gave him immediate mastery over his new Dojutsu?
What do you think?
