So why does the statue crumble? Because it’s empty. Because the spirit of the Great Stone Dragon has already awakened and given Mulan the strength she needed to make her decision and go to war in her father’s stead. Mulan woke the dragon when she sang ‘Reflection’ beside him, and he gave her his spirit when she sat in the rain watching her father, passing to her all of the strength of the Great Stone Dragon. So when the ancestors try to wake him, he’s already gone.
