Hello! Now that I'm not in a rush to have my knee scanned by expensive technology, I can introduce myself properly. I'm Ally! Welcome to the game!
I play many men. Some of whom will definitely at least know Elladora. I have:
Terence Higgs: He's a hitwizard, so they obviously are going to know each other. He joined the hitwizards two weeks ago, essentially straight out of the Muggle army. He's also married to Alicia, but no one knows (apart from all those people who do). I don't think he'd know Mafalda?
Oliver Wood: He plays Quidditch. All the Quidditch. I don't think he'd know either of them but he is totally down for having sexual relations with both.
Evan Potter: He is literally too young to have any idea who either of them are. Sad times.
Zacharias Smith: He's an investment banker and an utter asshole. He would also like to have sex with both of them.
