So Abigail, a changeling fae who has magical powers and a whole new set of gods or god-like beings, is going to go home to see her parents, who are fairly traditional (I think) people living in a very Christian country. She plans to tell these people, who are presumably, y’know, pretty Christian, that in addition to all of the above she also has one brother who’s a werewolf and a sister who’s a banshee. Basically tell them in so many words that they’re all creatures of darkness and the night.
I’m thinking exorcism. Violent, screaming, painful exorcism attempts over and over for as long as it takes for Abigail to flee the scene.
ETA: And then I’m thinking one of her sibs finds out too late and gets caught and more exorcism.
