Sneak Peek | Linen & Curls, 51
"Sirius came and told us what he'd done," Orion agreed. "It took me a while to break the blood magic vow that you and Sirius had made to one another — rather impressive that, darling —" he complimented her, making Hermione preen, "but once the magic was broken, he was able to tell us everything that you had told him."
"Sorry," Sirius said, looking at her. "I know I wasn't supposed to tell anyone."
"'S okay," Hermione reassured him. If she wasn't in the past, she supposed she would want Orion to have the clearest picture about Voldemort and everything that would come to pass. She hadn't told anyone but Sirius about how he'd died and managed to come back to life, to terrorize them again once Harry started at Hogwarts.
"With the knowledge that Voldemort would be killed, it was clear to me and my father more than ever that the Black family could not support him. We would not put the might of our family behind a losing horse," Orion described. "It caused significant disagreement in the family."
"What do you mean?" she asked, confused.
"It means that Pollux and Cygnus thought that they could throw around their weight. Pollux wanted us to follow Voldemort now more than ever. And, he thought if Grandfather was too weak to do it, maybe he should be Head of House," Regulus explained with a snort. "I don't know who he thought he was convincing — even Cassiopeia couldn't stand her own brother."
