Had some thoughts, and I've wanted to ask if anyone ever explored the idea of what the relationship between a Demeter demigod and Demeter's god daughter, Persephone, would be like. I would imagine something like that would make for great conversation, or...it could be nothing. I figure I'd direct the idea discussion to [@Altered Tundra][@karamonnom] since they're the only other ones with Demeter kids (that I know of). 

Though, as I think about it, it would be the same sort of scenario with say, A Zeus kid and Heracles, yeah?
