He started it.

He'd been the one to throw the first curse at her. He'd been the one who had encouraged her to 'do better'.

He'd been the one to fall first.

"Bella, he was the last male Black!" Narcissa groaned.

"Nearly the whole world believed him to be an escapee murderer, Cissy; I highly doubt he'd have raised children, anyway," Bellatrix muttered dully, glancing at her sister from behind the mass of curls that hid her face.

"I suppose you're right," the blonde woman sighed, shifting certain ornaments around on the fireplace. Since she'd heard of the murder of Sirius and the capture of Lucius, she had been unusually insistent on tidying the Malfoy Manor.

"I am-"

"But that gave you no right to go and kill him! For all you know, there was someone in the Order that would have been happy enough to marry him and raise his heirs!" Narcissa went on, as if Bella had made no attempts of talking her into her innocence.

A noise similar to a snort came from the dark featured sister.

"Why did you have to duel him, Bella?" Narcissa asked softly, facing Bellatrix.

"He started it," she mumbled.
