i think they would have a lot in common based on her bio... i'm still deciding if she's going to be beauxbatons or hogwarts but either way maybe since they're both in the luxury business they have shops close by and they've befriended each other? sorry if that's a boring idea i would love to think of something more interesting too
also she's definitely still going to have the luxury fine jewelry/crystal shop but i'm thinking instead of the stolen goods route she's a madam...
