Re: Why Tobirama and Hashi>>>Minato.
He didn't say shit about naruto being Senju. That's you reading too much into a throwaway line from a habitual liar. We know Naruto's lineage as Uzumaki and Namikaze. We know the Uzumaki and Senju share a common ancestor, the younger son. We know that, with that common ancestor, he has his link into the battle of the sons. He doesn't need to be Senju. And, for your "theory" to work, Tsunade had to have given birth at 13 for either of his parents to be her kid.
