I can give you Sara Hyde, fellow auror and middle class lady of colour who will probably hate Henry on principle. I would love it if they formed a hatemance <3

Additional Ministry peeps are Konstantin Fisk and Marlena Scamander with the former more likely to be his work bro. Kons has a touch of social climbing about him so he would probably enjoy Henry.

ALSO there is Sybilla Rowle who sort of does love her husband but is very confused about wtf happened to him and could do with a shoulder and for me to finally flesh out her family relationships!
