As soon as Narcissa was sure that Draco was out of earshot she turned on her sister, still clutching the Walnut wand in her hand as well as her own. She was having an incredibly hard time controlling her emotions, but felt that now Draco was gone she didn't need to.
"Bloody bitch," she growled. Narcissa never cursed because it was unlady-like but she felt that this situation heeded the curse word. "How dare you come into my home and threaten my son? I heard the crutatious curse. I'm sure it was you who cast it. Get out of my house before I hex you so badly you won't know which way is up."
