I don't think it would of affected T'Challa showing up in Hickmans NA or AvX. I don't think Namor flooding Wakanda had anything to do with his involvement with Storm TBH. In TRO I also think that T'Challa could of kept Monica in the dark just fine. I mean Reed did, it. So did BB. I would say that T'Challas marriage to Monica though would probably end with TRO though.
