So put your selfish, self-centred loathing aside for two minutes and ensure your fucking family safe!" Because that was his family now. The Potters were his family now. Regulus wondered if Sirius knew they were orphans. If Sirius knew they were orphans at his hand. He wondered if Sirius would care. He knew he wouldn't. When the crimson —the life of his usually dull parents tainted his fingers; that was when he became truly alone. The final true Black. Sirius had been blasted off the family tree for years. Regulus was the end of a Dynasty.
