He stood and watched in sheer awe as a slurry of emotions washed over him. All the fears and expectations she felt along with the constant reminder that she had life growing within her now were shared between them both. For him, it only became a reality when her labor began. He was torn between the screams of pain his beloved was enduring and the thoughts of what a father is supposed to be. This once in his life, he was completely humbled and unable to take command of the situation. The best he could do now is hold her hand and whisper words of encouragement into her ear.
With a final scream from his tired wife a new scream had begun. His attention was drawn to the new tiny bundle making all this fuss. The midwife cleaned the baby and announced, "It's a girl!", while passing her off to her eager father.
Zuko looked down to see a beautiful little girl with pale skin and dark hair just like his. She opened her eyes to reveal the same fiery gold color they shared. At that moment, Zuko could not imagine another man ever loving her as much as he already did. She was perfect and innocent and more so, she needed him to love her in a way that was foreign to him up until now.
He turned his attention to Katara whom seemed to still be in much pain. He wanted to show what a beautiful being she brought into this world. As he leaned over, he heard the midwife demand once again, "Push!"
With a final push that exhausted all her efforts, a new scream filled the room. Zuko's eyes turned to a look of shock and confusion. Here the midwife now held a new tiny being in her arms as she frantically worked to clean it off. It was a sense of deja vu for him and he had almost forgotten he was already holding a baby. The midwife turned and announced with a smile, "It's a boy!", and she passed him over to Zuko as she did with his daughter.
He examined the little boy as if he was fictional. He was in a state of disbelief when a pair of icy blue eyes opened and began to shine against his dark skin and light brown hair. He was absolutely stunning in appearance. His heir had arrived. It was now up to him to raise the boy with strong morals and to teach him how to divide right from wrong. And of course, show him the love his father never showed him.
Holding one in each arm, he glanced down and saw an unlikely pair, much like Katara and himself. They were as opposite as any two people can be. Boy and girl, light and dark, soft and strong. He now possessed his very own living example of yin and yang. He approached Katara and kissed her softly as he held the two babies up for her to look over. Their lives now forever changed. The journey of the unknown had just embarked; regardless if the young couple was ready or not. Before them laid their legacies in living flesh. That night, just a child was not born, but a whole family and a new history to be written came to be.
