Zuko, the boy who loved sitting with his mom is the heat under her favorite cherry blossom tree. There was a mother, a father and of course a spoiled little sister in his whole family. His father was of military, a king no less… and as king he had a responsibility to make peace instead of war, according to the Avatar that is. So it was his job to make his eldest son, the one who would take the thrown after him, to marry someone not from the Fire Nation.
When Katara was just 8 she was summoned, as a princess of the Water Tribe, to visit the prince of the Fire Nation once and see how they responded to each other. She had a mother, a father and a somewhat funny older brother. She loved her family and learned everything from her mother. Once the meet will they want to be together, or will Zuko and Katara fall a horrible fate to a fire in the palace.
