Sakura may hav an ancestor

[FemmeFatale]

I doubt sakura is related to the uchiha....

I don't think they reproduced, or they could've would explain that one pink hair Uchiha lol.
And Sakura's talents which are simular to an Uchiha's, genjutsu affinty, genjutsu resistance, intellect, learning jutsu instantly , ect. Lol.
Also shachi was said to be like the female version of indra
