He pauses, and his eyes fall downwards for a moment, then flicks upwards again, "My...my very best friend, Sirius, was a Pureblood, and he became a blood traitor, too. There’s some true bravery that it takes to leave that. Sacred 28 Purebloods operate on a culture of family, connections, and money. As long as you have all that through family, you have power. Power is the most important thing. Power is what really separates you from everyone else, you see."
