I have Gus here as a fellow professor, and he tends to get into trouble simply because of his own actions lol. He travelled around the world as curse breaker, albeit he left the year she returned. They could always bond over it.

Student wise, I think Cadogan Glynn might take her class.

Although a former student, I have Idris Oakby who is a feminist, so she might have latched onto Themis as a mentor while she attended Hogwarts.
