Hermione wasn't sure if something clicked or something had snapped at that point. She didn't really care. She was stranded on an island and she finally realized no one could tell her how to think or act here. Slowly, Hermione untensed her shoulders and relaxed her hands as she took a slow step toward the enraged man. "That's quite an accusation to make." She could almost hear the words of an old textbook reaching out to her as she continued to walk towards her prey: The effects of Amortentia on a person are described to be near instantaneous; with the person who drank the potion appearing "pale and sickly" and becoming obsessed with the object of their affections, speaking of them as though "hit by a ray of purest sunlight" and becoming excited or dangerously unstable towards others. Particularly when they feel others are going to keep them from the object of their affections. Hermione's decision on what her next course of action was came to her as quick as adding two plus two did. She didn't have the time nor the space to keep Richard quarantined in an area for the love potion to wear off and the last thing she needed was to have a third person trying to hunt her down. It's me or him and I choose me. "Richard, please give me my wand. I don't want to hurt your Draco." I'll make it quick. Like euthanizing a sick dog. Hermione didn't feel bad about dehumanizing her prey. With the potion in his veins and how he started to crack under being stranded for three months, she felt she would be doing him a favor.
