If you think that's bull shit. Just wait till Sarada unlocks EMS despite the fact that the Manga clarified only Indra transmigrates can achieve EMS.
Watch it either be Byakugou when the Manga clarified that the eye losing its light is based on a seal/curse in the eye, not a medical problem.
OR
She'll literally just have perfect MS like Obito but without Hashi-roids cause 'daughter of Indra reincarnation'
OR
Somehow she'll get EMS by switching eyes with someone, when again it was clarified that only Madara/Sasuke could do it thanks to be reincarnations.
Still its not surprising. The series will end up retconning itself sooner down the line b/c of new writers
Right? It doesn't make any sense.
And Obito saw Kakashi get slashed in the eye and started off with second tomoe.
