League
It was a a peace summit hosted by the Fire Nation, five years after the war. Sokka was one of the chosen delegates to represent the Southern Water Tribe. Unfortunately for him, Han was chosen as a delegate to represent the Northern Water Tribe.
"Hello, Soulless Prick."
"Hello, Unsophisticated Peasant."
"Why can't you two be nice to one another?" Katara asked, exasperated. "We're here to represent our tribes, not pick fights with one another!"
Han snorted, "Who are you to order me around, girl?"
"Hey, don't treat my sister like that." Sokka snapped, pushing Han away from Katara.
Han was about to retort with a scathing comment but a cough interrupted them. "As charming a display that was, I would appreciate it if you would move out of my way."
"Uh, sorry, Azula." Sokka stepped aside eagerly, dragging Katara with him. A dazed expression spread across his face as Azula and her train of Dai Li agents walked past.
Han laughed at him as soon as the group was out of earshot. "Dude, you might as well give up on her while you're ahead!"
Sokka frowned, "What? What are you talking about?"
"I saw that look on your face." Han snorted, rolling his eyes, "She's way out of your league."
"Whatever, I'm not here to flirt with princesses." Sokka said loftily, trying to keep his composure...or at least find it again, "I am here to represent my tribe and promote--"
"Excuse me," A Dai Li interrupted him. "Master Sokka, Princess Azula would be delighted to have you accompany her to the formal ball this evening." Han passed out.
"YAHOOOOOOOOOOO!"
Katara sighed. So much for giving a good impression to the other nations.
