This is something I just thought about. Black zetsu said only madara and the rikudo ever awakened the rinnegan. I mean, she ate the shinju's fruit and gained some of it's power. Her son inherited chakra from her and was later able to awaken the rinnegan. This means that his rinnegan came from the shinju. Shouldn't his mother also have awakened it given that she obtained chakra directly from the shinju? And it was her chakra that was passed to her son?
