Hi Kat! I've been around HP RP for ages, so we might have been in a game together before!
She might know Alicia through the twins! Not sure if she'd know Melinda, but probably recognizes her! That year was pretty hectic for her. Although she probably is a fan of her shop now. Sadly I'm not sure she'd know Finbar. Fleur is a fellow cursebreaker so she certainly knows Rose!
