I've read recently that when Paris says he's Ike's descendant -- specifically, this line: 一応、蒼炎の勇者の末裔だ。-- he says it in such a way that suggests he may not mean a literal descendant. I'm skeptical considering the source (and for other reasons), but does anyone care to weigh in? My knowledge of Japanese is pretty limited.
Kinda old, but:
For what it's worth, Mia says at the end of PoR that she wants to stay with the GMs to train under Ike, so a Rhys support isn't really necessary as justification. I understand what you mean, though.
