onto the topic at hand. both bill and peggy become even more insufferable as each reinforces the others' worst tendencies. they both become even more smug and authoritarian. they essentially become karens. bill attempts to attain a higher position in the military. peggy stays much the same, maybe interacting more with military wives / military wife orgs.
if bill's father is still around, he is sure to cause arguments between bill and peggy, which is a difference between bill and hank.
despite his weak appearance, bill is actually an incredibly headstrong person. in the existing canon he makes few choices because he thinks every choice he makes is wrong, but if he does make a choice then he believes that choice to be absolutely correct until he is completely humiliated and all his opportunities are dashed.
as for why old man d'hauterive may be around, bill may attempt to use his father's influence to help him rise in the military. of course, this backfires because his father is also very headstrong and hates weakness (what kind of a guy will make his son wear a dress when he fails at some small task?). his father will see this as an opportunity to test bill's resolve and worthiness, thus actually making the task of climbing the ranks even more difficult. bill whines to the men on his block.
peggy needs to believe she is married to a strong man. if bill becomes emasculated by his father, she will lose affection for him and may even become a nag like lenore.
if bobby is bill's son, then without the guiding example of hank, he becomes a self entitled douche. i'm inclined to think old man d'hauterive will be ok with that so long as bobby is still winning where it counts.
