Fire Emblem: Awakening Support Convo Reference

[gaiages]

Hey, so, when I was playing Awakening a little bit ago, I got Donnel+Cordelia's C support. The conversation is interesting because it seems to reference Caeda from Shadow Dragon (and the like three other games she's in). Here's a video of the support (Reference starts at 1:20):



However, I can't completely confirm it except for one thing... can anyone tell me if there's a mention that Marth is the first Exalt of Ylisse? The reference fits Caeda pretty perfectly, but since Ylisse wasn't Ylisse back in the time in Shadow Dragon (I don't think), I'm at a sticking point.

Thanks to anyone that helps. :)
