She didn't trust herself to even try to use the cloaked magic again. A concealment charm would have been welcome. Her nerves, however, weren't up to trying. From the moment she stunned Aberforth Dumbledore and had to flee, she hadn't been able to sit still for longer than a few minutes. Summoning up the necessary relaxation required to cloak wasn't going to be possible. Even her hands still trembled. She would never feel guilt for what she did to the horrible man. He grabbed her arm and she would no longer suffer the indignity of being grabbed like that by a man without dire consequences being meted out. A woman had the right to defend herself from danger. She would never feel sorry for what she did. She might regret the consequences of her instinctive reaction to being grabbed, but she did not regret defending herself.
