Before Helena could touch the ground again, after the last hit, her head was lifted by the hair. She could barely even feel that pain, not since the branch had been hit across the back of her head again. Slowly, she could feel the lids of her eyes drift down, she could feel the consciousness drifting from her.
As if, from far in the distance, she could hear Bellatrix still talking to her, telling her that no one would ever want her, she didn't deserve anyone. Her last thought was that she was right, before she lost all consciousness. She was out before Bellatrix even dropped her.
