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 youād 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 fatherās door. Mainly because he openly admitted he wasnāt perfect which none of the other men had ever dared to do. Theyād 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 Sokkaās 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 couldnāt 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 "iām pretty good with a sword and i know a lot about the fire nation....iād 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, iāve 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 didnāt vouch for him earlier because you thought it was Aangās place not yours and he understood your reasons. You caught up over everything youād missed in the fire nation and Zukoās 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 thatās odd?ā. Sokkaās eyes drifted back to where you were both sat together "and now they're sat laughing and joking around together". Katara sighed "iām sure they're both just happy to be around people they know, Zuko probably just feels more comfortable around her because sheās from the fire nation too, she knows what itās 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 couldnāt 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 itās freezing". "I donāt feel the cold" Sokka said and you snorted "you donāt 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 shouldnāt 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 donāt want to listen to Zuko be hilarious and watch him become even better than he already is". You paused "Sokka is everything okay....". "Why didnāt you tell me you knew him?". You paused "i...it didnāt come up plus i wasnāt sure it was relevant...I knew Zuko a while ago, itās not like weāre 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 itās 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 canāt believe you dated?". You shrugged "i donāt 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 iād never dated anyone before Zuko...that was half the appeal! The other half was heās a prince, which when i was younger seemed amazing. Iām 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 doā. 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 wasnāt my boyfriend and i...wait girl you've fallen for?". Sokka blushed "well i figured it was pretty obvious...wasnāt i?". "No but even if it was hearing you say it...iām falling for you too Sokka and thatās why this whole Zuko thing is just...so what if iāve dated and kissed Zuko? Thatās so far in the past! I donāt feel anything for him anymore and even if i did thereās no way itād 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?". "Isnāt he like 40?" you asked and Sokkaās smile dropped "ow so if he wasnāt then he'd be an option". You got worried Sokka was actually upset when his frown was replaced with a smile "iām 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 thatās what you like so much about me...my winning personality". āThatās one of the reasonsā you grinned and before Sokka could ask you to list all the reasons you tugged his hand ānow can we go back to the fire? I donāt have your water tribe protection from the coldā. Sokka nodded wrapping an arm around you ālet's goā. 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.
āThey look happyā Zuko commented to Katara who nodded smiling. She wasnāt technically speaking to Zuko but she loved you and Sokka as a couple and it melted away her anger. āThey areā she smiled. āIām glad y/n found someone, she deserves someone goodā. Katara frowned as Zuko was obviously talking like he knew you well but she didnāt push it. She just smiled seeing her brother so obviously in love with someone who loved him back just as much.
