Regulus laughed outright now. "Sirius was hardly the only mad Black. You remember Bella, don't you? I loved her, but she wasn't exactly a paradigm of sanity, and I'm told that you were in my house. You must have met Mother. Sirius seemed downright normal in comparison."
He sighed and nodded. "I know what you're telling me, Severus. I understand, but he is my brother, and my only close relative. Narcissa is- she has her own family. I was hoping to keep him away from them and I managed it to until James Jr. arrived. There's always one, isn't there?" He shook his head. "Never mind Sirius, how are you? Any plans other than living here?"
