The closest I remember is BP and the crew where he had T'Challa state he wielded absolute power in his hands abd could alter reality abd rhe heavens... but was too afraid to restore his marriage.
Yeah I know iron heart had a little arc ib Wakanda but this BPs book. It would make sense if a Shuri book was going on but it makes no sense for her to be fighting an invasion in Wakanda right bow for multiple reasons. Plus I thought it was mentioned at some point that Coates BP take place before SE
