Since at least a few people remember the whole Battleworld situation and know that Reed and co. (and especially Alex, whose family might be pretty miserable about it) are off doing cosmic stuff, shouldn't they, well, go and quietly inform the loved ones of the presumed-dead folks that their loved ones are in fact alive and off doing cosmic stuff? They don't have to explain the whole world destroyed and reborn stuff, but (if I had kids) I know I'd rather know one of my kids was doing OK...
