The main thing I don't get at the moment is why such an old and experienced Moira would make the mistake of marrying Joe MacTaggart when Xavier goes off to fight in Korea. Makes me wonder if the marriage and birth of Kevin were a feature of the missing lifetime VI, intentionally recreated in X. Also, Deadly Genesis doesn't really make sense if Moira and Xavier are running a two-man con based on her advance knowledge of events.
