She wore a collar that read property of Hermione Granger. But, today her collar was being changed to one that read property of Hermione and Bellatrix Black. Ginny had initially been worried when she found out her Mistress was marrying Bellatrix. Her concern was that she would no longer be needed to serve and pleasure her Mistress. Hermione had reassured her that she was not going anywhere. She had promised that Ginny would carry her children. Bellatrix could not carry children due to damage for her years in Azkaban. Hermione had no desire to be pregnant and carry children. Ginny was their solution for the desire for children to be raised in service of the Dark Lord.
