This. People acting like this is some permanent separation must've read a different book. This was clearly set up and whether they end up together again or not the X-office is going to milk T'Challa and the BP mythos for Storm-related content both for her big upcoming story and whatever they do in the future.
They don't know what to do with her otherwise and I'd be disappointed if it weren't so ironic. And really how many Wakandans are gonna miss Storm anyway lol. They had a whole pantheon before she got elevated to godhood through their prayer, they'll want the sword back, not her. But this isn't the end of that storyline unfortunately so we'll see where they go.
