What if she could use her medical ninjutsu to sever or negate the chakra pathway sending the hormones of the Sharingan into the eyes and brain. Then he won't have anymore hatred.
if she did that she will make things worse. He would lose EMS (which made him powerful) and he will powerless plus he has no curse mark anymore. this topic is so bad *facepalm*
I dont think that will ever happen but i know she is gonna heal him if he got injured. she can heal thousands of people far away from her currenty she is the best healer .
