They have really been going out of their way to have Shuri show up when T'Challa is involved in scientific talks in these books. She is showing up on book's she isn't a cast member in. It's being talked about because it's creeping on quite a bit. Think about it, a character who is a supporting cast member of a heroes book who has had 2 failed minis, no Moniker, and no ongoing.. Is consistently showing up and getting tech/ science feats in book's she isn't even in while T'Challa IS on the book and is fully capable of doing the things being delegated to her. That doesn't happen to T'Challa, he isn't getting credit on FF or Iron man books or getting name dropped like that.. and he's been around for 50+ years. Shuris been established as a super genius since 2018... Difference in treatment is huge and it's only going to continue to creep in.
That's the root of the problem I think
