Shuri will probably end up helping Stark Industries (which may end up with a Wakandan branch) given the post second-snap chaos.
By the way, hers is an interesting position. Wouldn't she be the one who ruled in Wakanda for 5 years? Is she supposed to step down again after T'Challa's return?
TBH, I don't actually remember much about the Wakandan rules of succession, though... but the dilemma would interest me.
