Does anyone notice Brother is always flirting with Yuna in X-2? I mean, aren't they cousin's being as Cid is Yuna's uncle?

I mean, that's kind of incestuous if you think about it. There are scenes in X-2 where he's absolutely acts stupid towards Yuna as though he's goofing around and flirting with her. I didn't think much of this when I was younger. But maybe their hinting that Al Bhed sleep with eachother seeing as Everyone else worships Yevon.

Makes sense to marry your cousin or....err whatever than.
