And last up on the "Addie's family bust parade" (at least for now) is Maggie, Addie's mother. Like her sister Lynn she's from Berkeley, California and spent a large chunk of her college days as a feminism activist. She met William during a rally while William was participating in a study abroad program at UC Berkeley. Though having very liberal ideals, Maggie is nowhere near as big of a hippie as Lynn, especially now that she's grown up and settled down. Like William, she currently teaches as a professor at the University of Oxford, specializing in women's studies. She spends her free time participating in student societies, particularly the LGBT and feminist societies.
Once I realized that split calico cats were a thing, I couldn't resist making someone in Addie's family a split calico. Not to mention splits get that fabulous heterochromia :3
