Just the same old stuff that haven't been answered properly, like the origins of Eve, pagan deities, and fairies. The others aren't really plot holes, but more of unexplored or unsatisfactorily answered territory like who were the other Knights of Hell, what rank Naomi had, and the episodes with more exciting concept but poor execution (Lilith Season 4 and Leviathans, mainly).
