Although Edith walked everywhere it was easy to believe she had simply appeared from nowhere as she had a habit of making no sound whatsoever as she moved.
She had walked quite a distance when she noticed a blonde that was out running. She stood silently in the shadows and watched the girl approach at relative speed.
She waited until the last moment before she stepped out from the shadows, as if she had stepped out of thin air in front of Buffy. She deliberately collided with the girl and staggered back a few spaces before she recovered and looked up at the girl. A slave it seemed judging by the mark on her wrist.
