The Dancer III

In book three, The Dancer becomes the Dancer Magnifique. And the story's focus is more on her daughter, who is now The Dancer.
She curtsied to herself in the mirror, and as she did so, her reflection in the mirror curtsied back to her. She tried it again, and without fail, the mirror curtsied back to her. What a marvelous invention she thought, a curtsying mirror. Of course it was just a normal mirror, but she liked being fanciful and pretending that it was a special mirror, one which obeyed her every command.
She curtsied to the mirror once more. Then fully assured of her command over the mirror, she walked away. But the figure in the mirror didn't move. She couldn't believe she was not in control of her special mirror, so she just kept walking out the door, even though her reflection did not follow. Besides she was late for dinner, her mother would be expecting her.
The Dancer tells her mother. The Shaman, the Dancer's Grandmother, insists that the Dancer must fix the mirror all by herself. Will anyone defy the Shaman and help the Dancer fix the mirror? How would she even start to fix it?
