Imagine Sokka becoming jealous when he finds out you and Zuko have a history together
Your father Piando was the best sword fighting teacher in all the four nations and people came from all over to seek his guidance. So you’d met many men who trained with your father but none of them were like Sokka, or more accurately Sokka wasn't like anyone else who passed through your father’s door. Mainly because he openly admitted he wasn’t perfect which none of the other men had ever dared to do. They’d openly boasted all their achievements hoping to impress your father whereas Sokka was brutally honest about himself and you respected that. Your father was intrigued too and so Sokka was allowed to train with him.
You were also very intrigued and observed Sokka’s training to see what this unique man would do. You watched amused as Sokka completed every single task with his own unique style and grew fonder of him with each passing day. You never interfered with your fathers training methods but you did help Sokka where you could and became friends.
When Sokka completed his training it was time for him to leave and you felt sad. It was nice to have someone so unique and refreshingly imperfect. You and your father both disliked the fire nation and your father always told you it would change eventually. Watching the avatar leave you couldn’t help but wonder if the time was now and realised how much you wanted to be a part of it. "Go" your father said suddenly and you paused "what?". "Join them" he smiled passing you a packed bag and your sword "i always knew you were destined for greatness and this is it....why do you think i pressed you to be so skilled with a sword? Go with Sokka and help him overthrow the firelord". You paused overwhelmed with emotion so you just hugged him "thank you". "You're welcome...just don't get any closer to Sokka okay?". You blushed but made no promises. You ran out of the house and caught Sokka as he was halfway down the road. "Sokka i..." you paused as Sokka and all his friends looked at you and you took a breath "i was wondering if you wanted any help defeating the firelord?". "You want to help us?" Aang asked and you nodded "i’m pretty good with a sword and i know a lot about the fire nation....i’d like to help, i want to fight". Sokka pretended to think before grinning "welcome to the team y/n!".
You worked with Sokka on his invasion plan for the fire nation and provided Aang with invaluable information on the firelord. You and Sokka grew closer and started dating pretty soon after you joined the group. You loved your time travelling with the gang and finally felt like things were changing for the better when a piece of your past came back to you.
You had just arrived at the western air temple and after finally getting Aang to talk to you were interrupted by the prince of the fire nation. Everyone rushed to attack him but you just stood there frozen between shock and awkwardness. Eventually you came forward to stand beside Sokka and listened as the others all debated letting Zuko join. Finally the group agreed to let Zuko join and only then did he fully look up from the ground at you all and he spotted you immediately. "Y/n?" Zuko asked and you smiled "hi Zuko". "Wait you two know each other?" Katara asked. "Yeah my father taught Zuko how to use his dual swords a couple of years ago". Zuko nodded "see her father is this amazing swordsman famous in the fire nation known for....". "Yeah i know, i’ve met him" Sokka replied "and he also trained me so you're not the only sword master here". Zuko nodded awkwardly and you changed the subject.
You showed Zuko around as nobody else wanted to and because you wanted to help make him feel welcome. You also wanted to apologise for not telling the gang you knew each other. You explained to Zuko how you didn’t vouch for him earlier because you thought it was Aang’s place not yours and he understood your reasons. You caught up over everything you’d missed in the fire nation and Zuko’s life while Sokka watched with a confused expression.
"I can believe i had no idea they were friends" Sokka cried and Katara sighed "y/n never said they were friends she just said they knew each other, also how would you know? It never came up". "Yeah but y/n knew we were conspiring against the firelord and she never mentioned she knew his son....do you think that’s odd?”. Sokka’s eyes drifted back to where you were both sat together "and now they're sat laughing and joking around together". Katara sighed "i’m sure they're both just happy to be around people they know, Zuko probably just feels more comfortable around her because she’s from the fire nation too, she knows what it’s like". Sokka raised an eyebrow not convinced. The way you and Zuko acted was way too familiar for casual acquaintances. You seemed very at ease with each other and Sokka couldn’t help but feel you were hiding something about this from him.
You were sat around the campfire drinking tea Zuko made with the group when you realised your boyfriend was missing. You searched all over for him before you finally found him. "There you are!" you called spotting Sokka stood at the edge of the woods "why are you all the way out here it’s freezing". "I don’t feel the cold" Sokka said and you snorted "you don’t feel the cold?" you asked imitating him mockingly and Sokka shook his head but smiled "i meant...i have more of a tolerance to it than you because i grew up surrounded by snow and ice" Sokka said nudging you playfully. You smiled at him and took his hand in yours "well that may be but i still think you shouldn’t be out here all alone, come back to the fire with me, Zuko was telling jokes it was crazy!". "No thanks" Sokka said abruptly dropping your hard and you paused "what?". "I don’t want to listen to Zuko be hilarious and watch him become even better than he already is". You paused "Sokka is everything okay....". "Why didn’t you tell me you knew him?". You paused "i...it didn’t come up plus i wasn’t sure it was relevant...I knew Zuko a while ago, it’s not like we’re close". "I thought the same thing but then i saw the two of you together and you seemed comfortable, familiar even and it made me think....has something ever happened between you two?". You paled and Sokka gasped "i knew it! You like him!". "What? Sokka of course i don't, i left to come with you right?". "So why...". "Okay so while he was being trained with my father we became friends and we might have maybe gone on a couple of dates...". "YOU WHAT!" Sokka cried and you jumped "Sokka it’s not that big a deal! It was like 4 times! Then he left for the capital and we never ever spoke again, you have to believe me". Sokka nodded his head as you stared at him fiercely "i do just wow i can’t believe you dated?". You shrugged "i don’t even know if you can call it that, it was just casual and fun, neither of us were expecting anything long term...it was literally just some fun". Sokka paused "is it...does Zuko still seem fun to you?". You shook your head "Sokka i’d never dated anyone before Zuko...that was half the appeal! The other half was he’s a prince, which when i was younger seemed amazing. I’m older now and not so easily enticed by titles or just any guy. It takes a lot more, someone as great as you" you smiled up at him "and trust me Zuko will never seem as good to me as you do”. Sokka smiled and looked at you "really?". "Really" you nodded and kissed him. Sokka was enjoying it before a thought popped into his head "wait when you two dated did you ever...have you kissed Zuko?". Your eyes widened again and Sokka gasped "you have! Y/n!". "It was only a few times!" you cried and Sokka gaped "of all the girls i fall for...her ex-boyfriend is the future firelord...". "He wasn’t my boyfriend and i...wait girl you've fallen for?". Sokka blushed "well i figured it was pretty obvious...wasn’t i?". "No but even if it was hearing you say it...i’m falling for you too Sokka and that’s why this whole Zuko thing is just...so what if i’ve dated and kissed Zuko? That’s so far in the past! I don’t feel anything for him anymore and even if i did there’s no way it’d ever compare with you...nothing and nobody could". "Not even a fancy nobel man?" Sokka asked smiling and you shook your head "nope". "Or a titled tribal leader?". "No" you grinned and Sokka smiled "what about the earth king?". "Isn’t he like 40?" you asked and Sokka’s smile dropped "ow so if he wasn’t then he'd be an option". You got worried Sokka was actually upset when his frown was replaced with a smile "i’m kidding" he grinned. "You're an ass" you said pushing him but Sokka caught your hands and pulled you to him swiftly. "Yeah i know that’s what you like so much about me...my winning personality". “That’s one of the reasons” you grinned and before Sokka could ask you to list all the reasons you tugged his hand “now can we go back to the fire? I don’t have your water tribe protection from the cold”. Sokka nodded wrapping an arm around you “let's go”. You and Sokka reached the fire and sat together, Sokka stayed close to you to try and share his body heat with you and you willingly leant into him savouring it.
“They look happy” Zuko commented to Katara who nodded smiling. She wasn’t technically speaking to Zuko but she loved you and Sokka as a couple and it melted away her anger. “They are” she smiled. “I’m glad y/n found someone, she deserves someone good”. Katara frowned as Zuko was obviously talking like he knew you well but she didn’t push it. She just smiled seeing her brother so obviously in love with someone who loved him back just as much.
