I see, it does make sense. It's probably that some parts of all the theories here put together to make the truth.with nagato it was a special case, you would have to look for the thread I made a while back, that tobi gave nagato his ems eyes , and after the traumatic experience it evolved, realize kishi has never shown nagato's normal eyes? realize nagato can't take off his rinnegan?
"As a child, his hair would regularly hang off his face blocking the view of his eyes; his normal eyes are never seen"
this is what i think tobi meant by , "I GAVE NAGATO THE RINNEGAN , IT WAS MINE TO BEGIN WITH, I WAS SIMPLY TAKING THEM BACK"
