idk. I always felt that Kaguya was treated unfairly. I mean, I get she isn't all good, but she wasn't all bad either. Could have been a good sympathetic character if she was given a better back story. It's pretty funny that Kishi just off handed her as a person by having Naruto say "she had no heart" even though we saw her crying for her sons. all to rush the ending (although SJ forced him iirc).
Plus, with Momo and Kinshiki gone, she has no need at all to make the Zetsu army. Although she should be nerfed by having her RinneSharingan stay sealed away by Naruto and Sasuke's sun/moon seals.
Hinata... oh, I'm not getting my hopes up for anything regarding her tbh. If it happens, I'll party hard. but I doubt we'll get much. For now, I'm just glad Byakugan has Precognition and she has Rikudo Chakra. Maybe if things go right, she can unlock Tenseigan considering she already has the needed conditions (Byakugan + Ootsutsuki Chakra) but, again, I doubt a power like that is being given to her ever.
