Thyra spent most of her time with Appa, looking after him whilst Aang trained with Master Pakku. Katara had to train with a woman healer since girls weren't allowed to waterbend in this tribe and Sokka spent all day either with Princess Yue or training with the other non benders, leaving her and Momo alone.
Thankfully that idiot Han seemed to get the message and left her alone after that, which suited Thyra perfectly well. Thyra was just about to take Appa out for some exercise when Sokka ran towards her, yelling loudly.
"Thyra! Thyra we need your powers of persuasion and scary authority to convince Master Pakku to continue teaching Aang to waterbend!"
"Whoa, slow down Sokka. What's happened?" Sokka clutched his knees as he caught back his breath before sucking in a deep gulp of air.
"Katara was annoyed because she wasn't allowed to learn how to fight so she and Aang decided that they could train together at night which was actually my idea but then Pakku caught them and he's now refusing to teach Aang and you need to make him take Aang back as his student otherwise everything has been for nothing and then Aang won't become the Avatar and then the whole world will explode and then we all die." Thyra just stared at Sokka then sighed.
"So it's up to big sister to get Aang out of trouble. Figures." She muttered then nodded. "Alright, let's go." Sokka led Thyra back up to the citadel where Aang and Katara were waiting for them.
"Thyra! It wasn't our fault, we were just…" Thyra lifted a hand and Aang instantly went silent.
"You see, why can't I do that?" Sokka demanded, gesturing to Thyra with both hands as she strode forwards.
"Because you're an idiot, Sokka." Katara answered, following Thyra to face the Chief and Master Pakku. Thyra gave a deep, respectful bow then addressed the chief.
"I believe my brother has something he wishes to say." She began, nodding to Aang. What Aang did say however, made Thyra clap a hand to her brow.
"You need to teach me waterbending otherwise I can't become the Avatar!"
"Yeah, you can't let Master Pakku refuse to teach Aang because he was just trying to teach me a few moves." Katara added, lifting a fist at Master Pakku who hardly blinked.
"What do you want me to do? Force Master Pakku to take Aang back as his student?" The Chief said.
"Yes!" Katara answered then hastily continued. "Please."
"I suspect he might change his mind if you swallow your pride and apologize to him." Everyone glanced to one another.
"I agree. Aang, Katara, you have to understand that in this Tribe, you have to value their customs and traditions as your own. To them they are sacred and ignoring them as rudely as you did will insult others." Thyra then shot a look to the old masters. "Even if their customs are completely outdated. Now both of you, apologise to Master Pakku and Chief Arnook." Thyra placed her hands on her hips and arched an eyebrow pointedly. Sokka squirmed.
"I hate it when she does that." Katara glared at Pakku then looked away, sighing with relent.
"Fine." Everyone waited as Katara put away her pride, Pakku smiling smugly.
"I'm waiting, little girl." Instantly Katara's hand balled into a fist at the insult, growling in anger.
"No! No way am I apologizing to a sour old man like you!" She yelled and as she did, cracks in the ice under her foot grew, spreading further with every word. When she pointed at Pakku the pots of water either end of the dais exploded from the shifting water from within which exploded upwards.
"Uh, Katara..." Aang tried to warn her but Katara wasn't listening.
"I'll be outside. If you're man enough to fight me!" With that she turned and stormed away. Thyra groaned and shook her head, giving up entirely.
"I'm sure she didn't mean that." Aang hastened to appease but Sokka folded his arms and looked pointedly at Aang.
"Yeah, I think she did." With that all three of them bowed to the chief then hurried to chase after Katara. "Are you crazy, Katara? You're not gonna win this fight!"
"I know! I don't care!" Katara yelled back, dragging her coat off to then throw it in Sokka's face.
"You don't have to do this for me. I can find another teacher." Aang said but Katara continued to rage.
"I'm not doing it for you! Someone needs to slap some sense into that guy!"
"Katara please. Fighting never solved anything…"
"Oh shut up! I'm sick of you telling us all what to do and your stupid peace making!" Katara bellowed at Thyra, making her flinch. "Just because you're the oldest does not mean you're the smartest!" Recoiling slightly from Katara Thyra lowered her head then nodded.
"Alright. Do what you wish." Thyra did not even bother to stick around to see what happened. She turned around and walked away, lacing her fingers together as she walked. Tears of hurt slipped down her cheeks but she hastened to brush them aside before anyone could notice them. She found Appa then climbed up onto his head.
"Take me to the skies, Appa. Yip yip." Appa leaped up into the air, flapping his large tail then glided up into the air where Thyra lost herself on the wind. Sucking in a deep breath Thyra closed her eyes then spread her hands, allowing her body to tip to the side. She fell through the air, falling through the clouds as Appa called out to her and dived down, angling to fly beneath her then rose up just moments before hitting the ocean. Appa grunted in annoyance at Thyra as she laughed.
"I'm sorry boy, I knew you'd catch me. I just needed to let go." She explained, rubbing his head before taking up the reins again. "Come on, show me what you've got."
