I am trying to figure out my feelings about it.
On the one hand, I thought it was a silly plot point, then and now.
On the other hand, it feels weird to ignore such a big story detail, even if I didn't like it.
On the other, other hand WAS it a big story detail? In the end the only thing that happens with it is he ends up being Governor, which we at least know isn't the case in ReMI, so maybe it's fine to just ignore it?
On the other, other, other hand, is it STILL going to feel weird to just have that plot point hanging?
On the other, other, other, other hand maybe the whole plot frame work and how they get from MI2 to the current story will also conveniently explain any weird discrepancies like this and we don't even have to worry.
