Hi Olive, I do not think we have ever threaded so I can not offer pre-established connections but here is what spurred my imagination when reading up on your characters:

Scallion and my new orphaned Hogsmeade rascal Leonard Blank, who is more or less homeless and loitering around the town for summer. You say she has a knack for animals, so maybe she would not mind a boy who would attach herself to her heels and follow her around like a puppy? She can be as ornery as she likes, he will put up with it.



Alastair Rosier is around for honestly anything intense that strikes you fancy for your UCs, most likely Ursula, Antigone or Mariana. He's a devil and can provide ample avenues for bad behaviour with his establishment in London and his criminal enterprises.
