I do think that is a good aspect. More so if their mortal parent didn't know, at first, that they'd slept with a Greek Goddess. And it even states in the Riordan universe that other gods do exist. I think one line in the Egyptian books state that they don't go to Manhattan because they 'have their own gods over there'. Which kind of reminds me of the Rose of the Prophet trilogy, which has it where all Gods exist, it's just a matter of what they want their worshipers to believe. If your god says they are the one true god, then their followers believe it. If your god says they are 1 of 20 gods, then their followers believe it.<br/><br/>So I think it's okay that he believes himself as a Catholic and the longer he stays at the camp and has to deal with his mother and the other Gods, he starts to question his faith.
