"Protego!" Ginny yelled as the hexes swirled around her. She felt something brush against her hair, felt the strands fall down her shoulder. She'd have to get a haircut when this was all over, something short apparently. Despite the fact they were in the middle of a battle, her thoughts turned to Harry and the D.A. They had never really focused on offensive spells. She'd learned a lot of defense, which was apparently Harry's style. She wondered if it were hers, if defending herself was better than attacking the enemy head on.

She knew the rest of her family was around somewhere. She could hear her brothers' voices. Ron had never gotten the hang of nonverbal spells. She bit back a laugh as she nonverbally disarmed the Death Eater nearest to her. Harry's voice filled her mind, that was one of his favorite spells. Disarm, don't kill, don't hurt. She fought the urge to roll her eyes. This was harder in battle than in an empty classroom.

"Ginny!" someone screamed. In the chaos she didn't recognize the voice. She'd barely had time to turn when something hit her shoulder. She snarled as pain shot through her arm. Her eyes scanned the room searching for her attacker. She spotted Greyback leering at her, his eyes seeming to be undressing her. For a brief second, everything she'd learned about defense, every spell and counter charm flittered from her mind. This creature was a monster and she needed to take him out, once and for all. She raised her wand, ready to finally give into her instincts to use something besides the defensive spells Harry favored.

"Depulso," she screamed slashing the air. Greyback was thrown backwards, his head being hit by a streak of green light someone else had cast. He fell to the ground. Ginny held her breath, she was certain he was dead. Had she done this? Had casting one spell, one spell that had felt so right led to his death? She should feel guilty about it, shouldn't she? A spell flew past her right shoulder and she spun, cast another shield charm and went back on the defense. The fact she'd been partially responsible for a man, maybe monster,'s death weighing heavy on her mind.
