Honestly, I would love to see Himawari join forces with Boruto Uzumaki, just like Sarada, Sumire, Sasuke, Koji Kashin and Shikamaru did, and see how Kawaki would react to that.
I feel like Kurama will tell her the truth about Boruto. Because what if since Kurama technically didn’t exist until after the omnipresence he wasn’t affected by it and has all his old memories before the spell
I think she will. After all, Kurama only recently awakened in Himawari. He was still dead when Eida cast omnipotence. This means he shouldn't have been effected by it. He'll probably be very confused when Himawari calls Kawaki "Big brother". He'll probably be getting on Kawaki's case.
