For those who were disappointed that Zuko didn't drink cactus juice, I've decided to fill that void for you all.
Sokka trudged through the sandy desert. There was no land in sight; it was only sand, sky and cactuses. The heat rays were getting to him causing him to sweat furiously.
"Katara! Aang! Toph!" He called lamely in a sing-song voice, knowing full well that no one could hear him, therefore not expecting a response.
He lifted his head for a brief moment and it was then that he saw it. A small stall set up only metres away as if it was just for him. The odour of meat wafted through his nostrils and it forced his feet to move toward it. "Meat, sweet meat," he drooled.
He ran at topknot speed toward it with the last boost of energy that he possessed, and when he finally reached the succulent meat slowly cooking it disappeared and he ran into a cactus. "Ow." He rubbed his forehead and looked the cactus up and down, sizing it up.
"Trying to play tricks on me eh cactus?" He asked it dumbly.
The next thing he did was take out his machete, and in one single motion swiped the top of it off. "See how you like that!" He spat.
Sokka then looked down at the cactus juice sitting in his hand, staring down at its glistening contents. "I shouldn't do this. But I am so thirsty. What would Katara say? Well Katara isn't here," Sokka argued with himself.
And before his good conscious had time to respond he threw his head back as the cactus juice fell into his mouth, making sure he got every last drop.
He stood still for a moment and dropped the empty bowl of cactus to the ground. "I feel fine. It must've been a dodgy cactus I drank from last time," he concluded dismissively. "Now which way to the City Of All Things Colourful?" He asked himself. Swinging his arms dramatically by his side he marched off into the direction of nothingness.
Sokka had been walking for a half an hour when he came across a figure.
"Um, Sokka?" The old man asked warily.
"Hello, Mr. Badgermole, what brings you to my birthday party?"
The old man shook his head and sighed, one eyebrow raised. "It's me Iroh. Have you by any chance seen my nephew, or been drinking cactus juice?" He added as an afterthought.
Sokka stared at him bewildered and seemed to think of his answer momentarily. His eyes were now wide and he said in awe, "Woah, I didn't know badgermoles could talk."
Iroh shut his eyes and slapped his forehead. "Come on Sokka, Ba Sing Se isn't too far from here, let me get you somewhere safe."
He said dreamily, "But I want to see the world and all of its beauty."
"Well you can do that another day," Iroh assured him, ushering him along.
As they arrived in Ba Sing Se they were met by both Aang and Toph.
"Sokka!" Toph shrieked. "Oh and Iroh, it's nice to see you."
"It's nice to see you too Miss. Toph."
"Wait, you know each other?" Aang asked dumbfounded, his mouth hanging open.
"Yes, but we'll explain that later. Your young friend here has drank cactus juice."
"Again?" Aang questioned.
They watched as Sokka pranced around the street, imitating what other people were doing behind their backs and mocking them with great enthusiasm.
"Well, I know this very nice tea shop not far from here, and I also know some tea that will fix him right up." Iroh smiled kindly.
Realisation struck Toph. "What about Sugar Queen?"
Iroh rose and eyebrow questioningly.
Aang sighed. "Katara. We don't where she is, see we all got split up, so she could be anywhere." He looked downcast.
"I'm sure Katara will be fine. Let's just get Sokka sorted out then we can think about Katara, OK?" They wanted to believe the kind gestured man, but in the back of their minds they couldn't. How could they be sure that she was unharmed?
Nevertheless, they continued to follow Iroh to the teashop. They had no choice in the matter really. By time the cactus juice had wore off on Sokka something terrible could've happened to Katara. And they knew whilst Sokka was full of cactus juice he would not oblige to go looking in the desert for her, nor would they want him to be near more cactuses when he was out of control like this.
"So, Iroh, why were you out in the desert?" Toph inquired as they sat at a table.
"Well my nephew went to go looking for you, and well I was trying to look for him because he has been gone for days and I was afraid he got hurt."
"So you think that he could have Katara?" Aang asked panicky, standing up from his seat.
"I'm sure everything will be fine," Iroh smiled warmly, as he began to persuade Sokka to drink the tea.
When Sokka had finally drained his tea, whilst Aang and Toph sat around agitated and impatient, Iroh asked, "Sokka, are you feeling OK?"
Sokka seemed to be bought back into reality. "What are you doing here?" He asked Iroh, eyes narrowed looking around frantically for Zuko.
Toph snorted. "Yeah, Snoozles is fine."
The bell tinkled atop the door alerting them that someone had walked inside the cosy tea shop causing them to turn around, which they had been doing since they arrived at the teashop. And there in the doorway stood Katara and Zuko.
And then it continued from the first chapter :) Well if you all still want more chapters, if I think of anything I'll add to this!
