Well here goes. I'm sorry if these all seem a bit serious and this chapter is going to seem way OOC but I liked the way it turned out.

Wanting
"If you help me and I win, I'll give you what you want," the Avatar had told him. But that wasn't why he had helped them finish off his father. No. The real reason was partly because he was heartless. The other was because of one word: revenge. He wasn't going to hide behind the usual excuse of "he was evil". Not him. The world was evil. Hell, people were evil. They had just killed a man for Agni's sake. What could be more evil? He wasn't going to pretend. He wanted revenge and he didn't care what anyone else thought of it.
He had wanted revenge. He had seen the surprised look on his father's face when he'd joined the fight. He didn't care. Every taunt that man sent his way couldn't affect him. He didn't care. He had seen the desperate look on his father's face when they'd cornered him. Still not caring. He'd seen his father shoot down Uncle Iroh in a last ditch attempt at victory. Uncle was dead. No tears. He'd killed his own father without batting an eyelash. Still nothing.
The Avatar turned to Zuko surprised.
"I'll keep my end of the deal. The throne is yours," he said.
"It's mine anyway. Everyone else is dead," Zuko whispered, harshly. The boy recoiled.
"Then what do you want?"
What did he want? He wanted his heart back. He wanted to feel emotion again. He wanted to cry. He wanted to mourn his uncle. He wanted those he loved to come back. He wanted someone to love him. He wanted someone to love. He wanted to care that he had just killed his father. He wanted to care that he had not long ago killed his sister. He laughed harshly through his depressing thoughts, making them all flinch and wonder what was wrong with him.
"That's just it. That's the problem, Avatar. I want."
