-Black Zetsu trolling the Uchiha clan was Kaguya's plan. He just carried it out.
-Indra was always a butthurt crybaby and his grandma knew him better than his father.
-Kaguya both loved and hated her descendants. Making Hagoromo sound like an even bigger idiot for saying she never knew love.
-Hagoromo was retconned into never having the Gedo Mazo/Juubi/Kaguya inside him. He only had her chakra.
-She had the Byakagan before eating the fruit.
