It hadn't crossed Hermione's mind that both sisters were quite happy to share her. if anything it was a surprise Bellatrix would allow someone else to get anywhere near what she had already considered hers. A silent rule that must have been shared between the twisted sisters. no one could have said they had slept particularly well the night before an inevitable war. Hermione spent most of the night thinking about her old friends and how she had slipped into this path so quickly. it was clear she had a very similar darkness, if not the same as Bellatrix and her younger blonde counterpart.
