A/N - Just a random plot bunny that popped into my head when I should have been doing something else.
"You're so mean, Bella! I wish you weren't my sister!" Eight year old Narcissa screamed.
"Well guess what?" Bella taunted. "I'm not really. You're a bastard, Cissy!"
"Mother!" Narcissa ran to the sitting room. "Bella said I'm a bastard and I don't even know what that is!"
"A bastard is a child whose parents weren't married." Bella announced, following her. "Mother was having an affair with Galahad Lockhart! You're not really a Black!"
"Bellatrix Elladora!" Druella admonished. "That is not true! Your sister is most certainly a Black!"
"Then why does she not look like Andi and me?" Bella demanded.
"Because she is the only one of my children who is a Black." Druella answered with a smirk.
