"Madness?" Narcissa repeated coldly, rising slowly from the chair. "What is madness, dear sister, is you abducting innocent pureblood children, a child you knew was of our blood because I told you so, no matter what the truth of that blood was, and holding her like some animal. That, Bellatrix, is cowardice, those are cowardly actions and you are more a coward than any I have ever met before. What I have come to say I have come to say on my own behalf. I have no doubt Regulus will deal with you in his own time and way, but you lied to me when I wrote to you and it is for that reason you will answer to me in part on this. You kidnapped a child. Such an action is monstrous and so far below your blood that I am forced to the conclusion you are no longer a Black as we were raised to be."
Behind Bellatrix, Rodolphus surged forward, but restrained himself before actually reaching both women and turned on his heel, moving to the window to hide the look of fury he sported, his cursing soundless but livid nonetheless.
Narcissa did not even turn in his direction despite his clearly furious pacing. Her gaze had not moved from Bellatrix, her posture had not weakened in the slightest and she had not retreated from the expectation of what her words would do. She had one thing left to say, at it was by far the most important and it was that she moved closer to say, until she was nearly toe to toe with Bellatrix.
"You are dead to me," she said quietly, the words emotionless but her eyes, if it were possible, even colder than before, "and if you or Rodolphus come near any of us again, I will not hesitate to eliminate you both as a danger, permanently."
