T’Challa and Wakanda are insulted and belittled every time they pop up in the X-books. Frankly it doesn’t matter how good a writer Ewing is, BP fans have a right to feel uneasy at his inclusion in any mutant related storyline because of the perpetually antagonistic ways the character is treated when brought up. And when virtually every appearance (with the exception of Avengers and the occasional one-off) depicts the character in a pathetic manner, I can’t say there’s much reason to think X-Men Red will be any different.
In having characters imply Storm was less than when she was with T’Challa, Ewing implies T’Challa isn’t worthy and isn’t willing to be a proper lover/ally to Ororo. Someone with that kind of approach to the pairing (one that should’ve long been abandoned anyway) doesn’t give me the impression he’ll give T’Challa a fair shake (whether relationship drama gets brought into it or not), especially when recent continuity has been exclusively focused on T’Challa’s failings. I fully expect mudslinging and disrespect even if it is done in a less hoodrat manner compared to the way Ridley loves to treat his characters.
