Lying in the snow, they watch the lights dance across the sky.
Katara tells Zuko stories of the spirits of the poles, of the ancient magic in every living thing.
She tells him of the first aurora, of how a waterbender lost her love and danced through the winter to keep his spirit close. How he saw her dancing and painted lights across the sky to keep her company. How the waterbender eventually joined him and their spirits have danced together ever since.
Zuko pulls Katara closer and her hand rests over his lightning scar. They could stay here forever.
