"You say that like it's easy." Barty wasn't sure if he was doing the right thing, but he had seen Regulus, right there. It was working. So he moved fully inside the circle himself, still holding Regulus' hand. He tried to hold Regulus, as best he could. "Your name is Regulus Black. Toujours pur. Always pure. The motto of your family."
