Lucy and Molly
Looking around the room Lucy tried to find Molly, or Lily. It was almost a relief to know that things would be over soon. They would win, Father would come back and they'd get Mother from Azkaban. Everything would be fine.
Finding Molly she smiled at her sister, "You be careful tomorrow," she told her. Molly may be the older sister but Lucy was the one with more experience in things like this.
