Hi Jamie! Olivia here. I have my four characters, but I think that Audrey would be most relevant for Annie. Mary is four years behind Audrey, Eliane wouldn't run in the same circles, and Decima could know Audrey but there's Annie. Annie is also an Auror in training, so they'd be co-workers. I don't know how close you'd want them to be, but I'm open for anything!
