"Is Dionysius your divine parent?" Or is he babysitter for all the half-god children? Strangly motherly for a god of intoxication and partying. But far be it from him to tell other pantheons what to do with their offspring. Well, until their offspring start killing innocent humans, but Cas doubts this boy is interested in that.

"And you thought I might be a monster to which you smell like a cheeseburger." Welp, their visits did us to start with 'be not afraid', so Cas can understand the concern. They are, in true biblical form, existentially terrifying, and prone to burn the eyes of mortals that look on them. "If it makes you feel better, cheeseburgers, and all other food, takes like molecules to me. So you'd be no more appetizing if you did."

Foregoing that time Gluttony was in town and he was non-stop shoveling Biggerson's burgers into his face, but that's the exception to the rule.

"Typically, before recent years, angels rarely visited Earth. We're soldiers. We protected Heaven, guarded humans enjoying their afterlife." It's an incredibly brief summary, and ancient times were a different beast (tools of God's retribution and all), as more recent times had him bounce from Heaven to play monster hunter with Dean, but that's a whole other story no one has time for.

"Yes, I can fly."
