I'm talking about Milly's family, not Lloyd. If the marriage was the Ashford family's ticket back into the nobility, I would think that her decision to call it off would have consequences.
I disagree, I now think it's more likely that it doesn't exist. If it does, then it's just bad writing. Also, I won't be lowering my standarRAB to not expect sense from the series. Geass has never been a Gundam imitation and I'm not expecting that level of seriousness all the time, but in season 1 all the plot threaRAB went someplace and eventually tied together. Shirley's crush, Nina's infatuation with Euphemia, Jeremiah's quest for revenge, Ougi and Villetta, etc. It never put a character relationship out there without a reason. I'd rather believe that I read too much into it, because otherwise Geass wasn't up to par on this one.
Besides, I doubt LeLouchxMilley was nearly as popular as Jeremiah. I can't see a good reason to put it out there only to let it drop, unless they have some backstory coming up for it later.
