well based upon what redjack said here it actually is consistent. Ororo's loss was hard on tchalla and it weighed deeply on him. he didn't push it aside so I would disagree there. initially I thought he pushed it aside and focused but Mr Thorne corrected the record there:

he even apparently activated his mask to shield from shuri and okoye how much her loss had trouble him.
