It really is a good thing that Aaron didn't wrote more than he had to and only focused on his dynamic with Khonshu, because I wince at the possibility of Aaron going into Marc's Judaism.
Like sure Marc isn't a practicing Jew, but at least he's not an ass about faith. Like the current McKay run features a nuanced discission about religion that Aaron just isn't capable of.
You would never hear Aaron's Marc admit that his father was the stronger man because he held true to his faith while Marc was the weaker one, who shunned the God of his people that lead them out of Egypt for the God of the people that kept them there.
