If that doesn't confirm DG is Hades, then IDK what is.

I highly doubt they'd make him the actual Devil (Lucifer), since people still actively believe in Christianity, and giving the Bible's stories and characters a Once twist might rub people the wrong way. Though David being the same one from "David and Goliath" would be amazing. Or would have been amazing, if "Tiny" hadn't already pretty much done it. And badly.
