I read several relationship and skill topics, and saw it stated several times that Chrom always passes Aether to female children and Rightful King to males. However, I'd never seen a similar point listed for Lucina.
So I decided to turn Lucina into a Dark Flier for Gale, so she could pass that to Morgan and Morgan could just be a Lord. However, when I got to Morgan's Paralogue, her skill was Aether. So is that the case? Lucina always passes Aether if she marries MU? Because that kinda screws things up for me.
