What had shocked Fred the most when he discovered your childhood home was its size and luxury. After all, you were part of the noble and pure (and wealthy) House Blac k, what else could he expect?
12 Grimmauld Place, the new headquarters of the Order of the Phoenix, was a four-story XVIIIth century London mansion with dark and grandiose details. The wealth of the pureblood nobility was expressed through its wallpapers, chandeliers and paintings. Fred could see that, despite some dust, you had made sure to keep this family home in the best possible condition.
You and him were quite good friends, long before things went bad with Volde mort. Your bond was created while you skipped your respective classes, finding yourself together in the empty corridors of Hogwarts. You spent your time together laughing and chatting lightly. Fred never asked about your family and you never told him about it. Until now he wasn't interested.
But after his family, his mother, his father, George, Ron and Ginny dropped off their stuff and you welcomed them with Sirius Blac k, he doesn't know who for you, around a meal that you had surely prepared, Fred was piqued by curiosity. Who were you in this family?
You were sitting across from Fred, between Sirius and Remus. You had finally sat down after serving everyone the French dish that you had prepared, a boeuf bourguignon and bringing a bottle of red wine for the adults (and you, Molly had to hold back her worry). The meal was dynamic and light but you could feel your friend Weasley's gaze on you.
"So you are..." Fred asked you, looking at you and Sirius in turn. "...related?" » George frowned as he stared at his twin as if to say: Do you have any more stupid questions like that?
