Hello and welcome!! I'm one of your mods, Sam, and (for now) I just have Rose Weasley. Being a Weasley she knows Dom, of course, but I'll leave it up to you how close you'd like them to be. They're both incredibly honest, though where Dom is trying to get better, Rose doesn't really see it as a problem. As for Amber, I'm not sure if Rose would know her. She graduated the same year Hugo did, though, so there's a chance she knows her through that? I'm always open to drama/back-story/plotting!!
