It's a bit weird that Obito was content on leaving, BUT Madara told him he would definitely be back, leading me to believe Madara set up something!
What do you guys reckon?
How would Madara of trained Obito when he is struggling to survive? Could it be possible that Obito is not Obito but in fact Madara's soul in Obito. Like Madara using Obito's body as a vessel like Oro wanted Sasuke's body as a vessel?
I can't see how someone like Obito would be brainwashed to...
