I'm wondering now if Obito's plan is to revive Rin. I don't know if anyone had thought of this before, I'm sure it's already been posted, but whatever. Anyway, If I'm correct after Nagato revived the people of konoha (Dying in the process) Tobi/Obito said that Nagato was supposed to save the rinne tensei for him. Back then most of us believed he must have been some sort of clone of Madara or something of that sort, or that Zetsu saved Madara, you know, blah blah blah fan theories. But is it possible that Obito wanted the rinne tensei to revive Rin? i'm not sure if the jutsu can revive someone who's been dead for that long, or if any of this is possible i'm just looking for feedback
