Chastity Bentley for potential friend? They overlapped at Hogwarts in Hufflepuff for Callista's first three years before Chastity had to drop out. She's Lower-Middle Class these days, but she was raised closer to mid-to-upper MC and would have socialized accordingly.

My only single UCPB dude is, unfortunately, Algernon, if she'd like an invalid old man. XD Unlikely for them to cross paths, as funny as hurling him at anyone is to me.
