@Thekillman Is in a way right. Sasuke technically has his own cells as a Indra reincarnation, and also possesses Hashirama's cells as an Asura reincarnation. But it's very unlikely that he passed both of this things to Sarada. And it doesn't actually work like that. Just because your parents are reincarnations, it doesn't make you one. You need to have both reincarnations parts inside you to awaken the rinnegan, and it being related to then is not enough. It's like saying that if Hashirama's children would've got their hands on Madara's cells, they would've awaken the rinnegan themselves, because they are directly related to Hashirama, which would've not happened.
