Sokka entered the most spiritual place in the whole North Pole, closing the tiny door behind him. He had left Katara, Aang, and Toph to play in the snow out in front of the palace, Toph trying to figure out how to build a snowman. He walked over to the tiny peninsula that went into the tiny pond. He sat down, watching the two Koi fish swimming around in a circle. They were Yin and Yang, better known as the Moon Spirit. He watched the white fish, the Moon Spirit in its mortal form, swim towards him.

"Hey, Yue. I know how you feel. But you have the Ocean Spirit to take care of you. I wish only I could have," Sokka wiped tears that were filling up his eyes.

Suddenly, a bright light started to from around the pond. The white Koi fish's eyes were starting to glow. Sokka backed up, eyes wide. What was going on? Out of nowhere, a beautiful woman in light rose from the pond. It was the Moon Spirit. Sokka moved forward slowly, holding his hand out. The young woman put her small hand in his, smiling.

"Sokka…I thought you would never come again," the woman spoke.

"Yue," Sokka muttered. "I've thought of you every day. You are always on my mind. How come you never come and see me?"

"This is my home, Sokka. I can never leave the Ocean Spirit. But in your dreams, I am with you. In your heart, I'm with you. Everywhere you go, even in the night, I am there. You might not see the moon on some nights, but I am still in the sky. I am just hidden in the darkness, protecting the Ocean Spirit in a different way," Yue spoke, putting a pure white hand to his cheek. Sokka couldn't feel it at all. She was just a spirit, an illusion. "I wish I could feel your skin, Sokka. I wish you could hold me without your arms falling through me."

"Yue, I never wanted this to happen! I never wanted you to die this way!" Sokka called out.

"Sokka, it was my duty. I was about to change my mind as well. I was going to stop the engagement to that fool of a warrior and marry you."

Katara opened the tiny door, and gave a shout when she saw the woman glowing. She just stood there, Aang and Toph coming from behind her. Toph gave a yell when she felt the ground. She fell back onto the ground, rolling around. She was now wearing a light green jacket that looked similar to Katara's, but it wasn't. Katara had a new jacket on herself, and since she was about to turn fifteen, it was a light purple. She now had the choice of continuing with the color blue, the traditional color of the Water Tribes, or choose a light form of purple, such as lilac.

"Is that-?"

"It is! It's Yue!" Aang said, mouth opened wide. "But I thought you said she died?"

Katara nodded, taking Aang's hand and running towards Sokka. Yue gave a worried look to him, shaking her head.

"I must go now. I can't let all of these people see me, Sokka. Remember, I will always be with you," Yue leaned forward, kissing him.

"Yue, it's Aang and Katara! You know them! That's Toph! She's an Earthbender!"

"Sokka, I am so sorry," Yue started to disappear, but Sokka grabbed her hand, which turned into the tan color.

"Yue? What's going on?"

Katara and Aang stopped in their tracks. Toph didn't know what was going on, since she was still rolling around in the grass. Yue was becoming human again. Her hair became white, her eyes started to become blue, and her clothes were turning back into that of her Water Tribe Princess outfit. Sokka pulled her out of the pond when she became full human. The Moon Spirit, the Koi fish, that is, was swimming lively. Apparently it was either Yue or the Koi Fish giving half of their life to allow Yue to spend a few days as a human.

"Sokka, I said I was sorry because I am going to give my life up as the Moon Spirit. The Koi fish will have a week to find someone who is willing to take the Moon Spirit life out of me and give the life back to it. I will still live, but that person will give me their normal life, and it must be someone young. My age," Yue put her arms around Sokka. "I'll be able to marry you!"

Katara put her arms around Aang. She would give her life for Yue, but she wasn't ready to become something like the Moon Spirit. Besides, she had to help Aang in the fight against the Fire Nation. Aang nodded, understanding. They would have to help Yue. It was confusing to understand what she was trying to tell them but they understood that she needed a young woman who was willing to give her life for the princess. Which was pretty much everyone.

"Yue, this is so…weird. I mean, it isn't weird that you are alive, but it's weird that you came back from being the Moon Spirit," Sokka commented, scratching the back of his head in confusion. "Okay, now I'm really confused."

Yue gave a laugh. Sokka had a dreamy look flow over his eyes when she laughed. Katara gave a snigger and tugged at Aang's hand. She pulled him towards the waterfall, taking him behind it.

"What is it?"

"I just want to spend some time alone with you. Can you believe I'm almost fifteen? In the Southern Water Tribe, I'd be able to get married! But we're still too young in my eyes," Katara blushed so red it didn't seem like her.

"Yeah, we're too young. Although I do want to marry you. I'd really love it!" Aang gave a laugh that seemed very happy.

Katara took her mitten off, looking at her small hand. It was the same size as Yue's, but it was a bit darker than hers. Although the two Water Tribes were sisters, they had their differences. Katara took off her other mitten and stuffed them in her pockets. She slowly traced the arrow on Aang's forehead, smiling softly. The waterfall slowly became ice as she felt herself become warm. She didn't realize it, nor did Aang. He took her hand from his forehead and held it in his own, then kissed her. Their eyes closed as they pulled close to one another, the kiss becoming something more. Katara felt something so exhilarating whenever she kissed Aang. It wasn't like anything she had ever experienced, and it was much different than being with some other guy. Although she had never kissed a guy before Aang, she was glad that he was her first kiss.

"Katara! Aang! We need to head back to the palace!"

Katara pulled away reluctantly, but knew her brother would get angry if they didn't reply. Turning the iced waterfall back into water and pushing the waterfall apart as if it were a curtain, she and Aang walked out in unison, a look of sadness in their eyes since they could never get any alone time. Someone was always bothering them or they were always practicing their bending. Sokka stood there with his arm around Yue. Toph had finally meet Yue, who she thought was a princess, but not the royal kind. Toph stood there next to them as well, arms crossed, hands still in green mittens. She had brown boots on her feet, which made her look awfully ridiculous.

"Can't we ever get some alone time?" Aang said, following the other three.

"Nope!"

"But you and Yue-"

"Aang, hush! We'll talk about this later!" Sokka stopped him, staring dreamily into Yue's eyes. "You've grown so much more beautiful than before."

"Sokka!"

Katara and Aang took a look at one another. They shook their heads. Katara whispered an idea into Aang's ear, telling him that they would come back here later in the middle of the night and allow it just to be the two of them. Aang nodded happily, wanting that more than anything at the moment.
