bobbi is also friends with her sister and is another veela, so i can offer her as another "so what's your deal?" if you want, and thoroughly confuse erianthe by getting it from multiple angles. also friends too, because obviously the goal is to collect all the selkies. bobbi was two years behind at hogwarts, or they could have become friends later down the road. maybe she ventured into discordia one day determined to finally get a tattoo, then noped out at the last second
