A/N: I like doing one-shots where people are suddenly thrown into situations with no other explanation than the A/N, for some reason. This is a prime example - Zuko was training with Aang, who is now trainign/cooling off with Katara, and Zuko's going to get changed. And whereas I know it's actually pretty out of character for Sokka to be a crazy-overprotective big brother, I do enjoy the trope often, and so I played around with it and twisted it a little here. I'm not quite happy with how it turned out, because Sokka's dialogue at times is very...Meh. If anyone knows how I could make it less "Meh", feel free to leave some advice and/or constructive criticism in those reviews!

Zuko exited the courtyard, about to head to his room to change, when, suddenly, he felt a hand firmly clasp his shoulder and pull him to the side. Zuko whirled around to see none other than-

"Sokka? What the heck are you doing?"

He tried to wriggle free from the Water Tribe warrior's crab-like pinch. Sokka shrugged, but released him, casually pulled out it his space sword and began inspecting its tip.

"Nothing much, just having a talk with you and my very sharp space sword."

The former prince blinked. Was Sokka trying to intimidate him?

"What are you doing, Sokka?"

Sokka frowned and jabbed his sword at the firebender.

"Having a talk. With you, and my sword, about my sister."

Katara? Why did Sokka want to talk to him about his very attractive sister? He glanced over at the waterbender, who was standing half-submerged, in the fountain, in just her bindings, which Zuko thought suited her very well. Realisation dawned on him. That was probably what Sokka wanted to talk about.

"Look, if this is about me maybe being a little into your sister-," he started.

Sokka started laughing hysterically in response.

When Sokka had finally calmed himself, he spoke, very seriously, twirling his sword around. Zuko wondered if he should take out his own swords and challenge him to a duel.

"Zuko, buddy, you're not 'into her'," he made air-quotes with his free hand, "you like her. A lot. So don't even try denying it. I've seen you staring at her, blushing, then look away one too any times. It hurts to see how oblivious the two of you are. Please, just go ahead and ask her out, okay?"

Zuko felt himself go slack-jawed at that

"What do you mean, 'ask her out'?," he stammered, "Aren't you going to hold a big speech about how she's your precious little sister and I should never, ever, hurt her or you'll come cut me up into tiny little bits with a sword?"

Sokka rolled his eyes.

"No, even though that sounds like a great idea, I actually want you two together, so I'm going to hold a big speech to boost your confidence and get you two ask her out. With my sword. I'm challenging you for a duel, if you win, you have to ask her out, if you lose, you have to ask her out - it's a win-win!"

The swordsman grinned widely and poked Zuko in the side with his finger, all whilst muttering, "C'mon, hot-shot. Let's go make you my in-law."

"What?"

"Nothing."
