Bibiana's friends (she prefers the term 'partners in crime') would be her little group, comprised of Madelyn Aqua, Allegra Para, Maura Delusory, and Rayne Yami. (Shoosh, Hailey, Shadow and Gracey were ditched.... I never once said Bibi was very loyal to her buds.)
Like most ghouls, Bibiana has been hit on by Heath Burns, but she prefers his cousin, Holt, and has tried to fight for him, Holt wasn't at all impressed about this. She's still trying to impress him.
