@EmmaGMaybank it's explained in the books and even in mythology that DNA doesn't work the same with the Gods, in the PJO series Percy said unless you're siblings on your godly side then it doesn't count cause the DNA isn't the same as mortals, say two Apollo kids got together, that would be wrong, but is a son of Apollo and son of Hades ;) got together it wouldn't matter that Hades is technically Apollos uncle. And yes everyone always makes Hades out to be the bad guy because the Underworld is "creepy" but in reality they're just scared of the power he'd have at full potential, everyone wants Hades gone but forgets that somebody has to rule the Underworld
