So here is Miss Grace who is 8 years old now and still fairly shy. Her older brother often gets her in trouble. While she does live in Irvingly I can send her to stay with her great aunt or extended family in Hogsmeade as needed and have her run into Charley in the park, would love if Charley terroized her, but then again everyone scares her so take that as you will.

I also have friendly shop owner Laurel Potts who would likely be trying to help Charley in small ways. Like delivering flowers or something. Or maybe Charley gives her a tough time and Laurel is trying to make it better for her but she doesn't want anything to do with her pity?

Everett Swann is a lawyer on High Street and used to be a trouble maker as a kid so that might be fun for him to get involved somehow. (He also has ties to the black market that no one knows about)

And if you want someone to antagonize, Ellsworth Ruskin is in Hogsmeade in the summers and could easily be the part of very annoyed elderly gentleman.
