It’s the memory of when she received the news about her parents’ incident in Australia, Draco leaving the safe house for the first time since he joined the Order just to get to her as she cried her heart out on the steps of her old home. Draco holding her when Crookshanks was killed in a raid by Death Eaters on one of their safe houses. Draco listening as she expressed her frustration with the Order’s methods and plans, Draco helping her, understanding her curiosity and leading her through her dark magic studies, making sure she could recognise what she could use and what would fireback and try to eat away at her magic and her soul.
