Hermione realized there were times he surrendered to her own wishes just for the comfort of submission. It made her question her own motives. Where Peter was a devoted minion, she was a different kind of animal. Her emptiness dictated to be satiated in other ways. The nature of her need was both physical and intellectual, spiritual even. Her magic core felt overflowed. It wouldn't stop replenishing, it had been overcompensating without release since He was gone. And that was her motive. To feed darkness, to nurture Him back to life. To be able to complete Him, meant to fulfill her own empty cavities.
