Sirius was your father. He had done it with a woman years ago, and when he found out she was pregnant, he ended it with her until his mother died. The orphanage called him, and he was forced to take you.
He never loved you. He was never gentle with you. You were calm and didn't oppose him, but he hated you and didn't love you. He loved Harry and cared for him more than you did.
He made you live with him unwillingly in Grimmauld Place. He also made the house paintings shout at you and insult you. You were only six years old. You were innocent.
You were sitting in Grimmauld Place at the long table, while Sirius sat at the head of the table. You were sitting in Remus's lap next to him Tonks.
Sirius was looking after Harry and laughing with him. Molly was cooking. Arthur was reading the newspaper. Hermione and Ron were talking. Fred and George were making jokes. You were listening intently to Remus and Tonks. Sirius added, "Stop spoiling him. It's not like he deserves it."
