To many in Bella's Duke Vampire household, Bella was known as the 'Tyrant.' And for good reason, as any who crossed paths with her, even the heirs of other Noble Vampire households, all ended up with terrible fates. Whether within her own household or outside it, none of it mattered to her. She would destroy the lives of anyone who messed with her, and that was even more the case if it involved her 'husband.'
Bella was already someone many looked down on for claiming a mere human worm to be her husband, but when she strutted around with her marriage to him practically plastered on her smug face, nearly all of Nightingale felt ticked off. Even the older generation vampires were no exception.
