ATLA: Critical Hit 2 - Lessons and Fun
“Come on, Zuko!”
“That is the stupidest thing I’ve ever heard. No.”
“But it’s for Aaang!” Sokka pleaded.
“I’m saying no for Aang! That isn’t what he needs. And that’s why I’m going to go back home to confront my Father!” Zuko exclaimed with a serious expression, up in Sokka’s face.
“Dude. Sparky.” Toph spoke up. “Do you really think what Twinkletoes needs is vengeance? He’s a vegetarian!”
Zuko raised his eyebrows and took a step back.
“Yeah!” Sokka jumped on. “He needs to move on! We’ve all been hit in the junk before. But Aang needs to know it’s nothing to cry about! It’s something to laugh about!” Sokka said with a smile, hands at his side.
“Smile about.” Zuko grimaced, looking down. “That never led to a smile back home.”
“Looks like it’s something you need to learn to smile about too, Sparky.” Toph said, approaching Zuko. “With a sister like yours, a memory like that might be one of the few things you can smile about!”
Zuko grimaced. “Me and Azula used to get along really well. But… things changed.” He said, looking away. Then turning back with a renewed determination, “But that’s not important right now! I’m not playing!”
“Come on! Aang will have more fun with you!” Sokka pleaded. “And I’m gonna do it with or without you.”
That seems to have caused Zuko some hesitation, looking down and considering. Sokka and Toph looked at each other with a shared grin. We got him!
“But… it’s so stupid.” Zuko said, looking up.
“Listen. That’s why it’s fun.” Sokka said with a smile, an arm around Zuko’s shoulder. “Plus. Don’t you want to get me back?” Sokka said.
“Get you back? For whaUGH!”
As Zuko looked confused, Sokka rocked a hand in and up towards Zuko’s lower midsection, swinging from down below. Sokka’s knuckles made healthy contact with Zuko’s meat and potatoes. The Exiled Prince Zuko’s eyes went out as he bent back and clutched his groin with a shocked expression. Then his mouth clenched with pain as he lowered towards the ground as pain rocked his core, and he felt it difficult to stand.
“Oooh! I’m soOOoO getting you back!” Zuko groaned, going through a wave of pain as he exclaimed his discontent. He stumbled and moaned out a little sickly before putting his head down and curling it in. With a grimace, he looked back up at Sokka, who was smiling and sharing congratulations with Toph.
Zuko yelled out as he jumped up and started to chase Sokka with a hand still clutching his crotch. Sokka shrieked out and ran away from Zuko, who was much quicker than Sokka thought he would be, post nut-tap. Then as Zuko started throwing fire bolts at Sokka’s feet, Sokka kicked it up a gear and screamed out again.
“No bending, no fair! No bending, no fair!”
