POV: Katara
Every time Sokka disappears without a trace, worry fills my heart. I know he's strong and very smart—even if I never tell him—but I can't help it. Every time he comes back, he's hurt in some way, with a broken bone or cuts on his body. Yet he always smiles despite our concerns.
But he always comes back, and I always feel the same fear. I don't know what I'd do if he left too—like Dad or Mom.
I always tell myself that Sokka does it to protect us, but I can't help feeling this guilt. If I weren't a waterbender, they never would've come, and Mom wouldn't be dead. Sokka wouldn't have been so badly hurt, and if none of that had happened... Dad would still be here with us.
End of POV
As Katara stared at the horizon, her fists clenching tighter, she felt a calming hand on her shoulder.
"He'll come back, Katara... he always does."
Katara turned toward the woman who was her grandmother.
"I know... but he's never been gone this long before."
"I know," Kanna said calmly, looking at Katara's face. "Knowing him, I'd say he'll show up with torn clothes, some new animal, and ideas for the tribe."
Katara couldn't help but laugh at the image of her brother doing exactly that. "He'll probably also suggest throwing a feast as soon as he arrives."
"Ha, exactly."
"You son of a bitch!" —a furious voice cut through their laughter.
Katara quickly turned toward the voice—it was Sokka. His clothes were so worn out they could only be used as cleaning rags, and behind him was a strange beast being dragged along.
Kanna's expression was pure disbelief.
"Where the hell have you been, idiot?" Katara shouted angrily, hugging him tightly and trying not to look at his scars.
"Ha! I went out fishing and followed something to a beautiful sanctuary where I found this huge animal. Turns out it was possessed by a spirit and attacked me, so I killed it and took its stuff."
Kanna watched as Sokka laughed while telling the story like it was nothing.
"By the way, think you can make me new clothes? These suck."
"Sew them yourself, idiot! We've fixed your clothes way too many times!" Katara snapped.
"Come on, that's women's work," he said playfully, watching his sister's reaction.
"Sokka." Gran Gran finally spoke. "Come with me, please."
Sokka said nothing and followed her—though not before handling something else.
"Tiga, here." He handed her a handmade knife made from a massive fang. "That guy's skin is super tough. The only thing that can cut it is its teeth and claws."

(She is Tiga in this story, although she looks very young, she is between 27-28 years old, and the AI always makes them either very beautiful or very old)
Tiga nodded with slight confusion as more similar knives were handed to her.
Without realizing it, more women had gathered around and headed to the big storage house where Sokka had left the lion on his way with Gran Gran.
"Come on, I know what we're going to do with these pelts," said an older woman enthusiastically.
"So, Gran Gran, what did you want to talk about?"
"Did you really kill that beast?" Kanna asked, genuinely doubtful.
"Of course I did. That bastard nearly cost me my limbs," he said, irritated.
Gran Gran looked at him hesitantly. "Then how are you completely fine? And what about that white streak in your hair?"
Sokka was startled by her words. Instinctively, he grabbed a piece of ice that served as a mirror and checked his head—he had a large white streak that almost reached the tip of his wolf tail, where the color returned to white again.
"I had no idea my hair changed color... Must've been because of that... But wait, did you know that lion? I noticed your reaction when you saw it."
Kanna was impressed that Sokka had noticed her reaction. "Yes... It's a story from when I was little. They used to say that hundreds of years ago, our tribe had a pond where the spirits of the Moon and Ocean swam, alternating between the northern and southern sanctuaries. But one day, a wild spirit arrived, one that craved the sanctuary. It drove the great spirits away to the north and, in its fury, destroyed the ancient village of the tribe. No one could stop it—not even the strongest waterbenders. Or at least, that's what the stories say. Honestly, I thought it was just a myth. My mother was the only one who knew that tale."
"Kanna's definitely good at hiding she's from the North..."
"Well, as you saw, that story is real. That bastard lion was practically indestructible. I needed every ounce of strength just to stab it a little. Punches worked better."
"I see," she said, understanding the incredible strength of her grandson.
"As for the white streak, after the lion died, I dove into the pond there. It was probably the leftover spiritual energy that healed me. I wished I could water bending—just a thought out loud, driven by the desire to heal—and then the moon shone on me, and I heard a voice. It said it would grant me the ability, but the more I use it, the faster I lose it. So, it won't last forever," Sokka said, recalling the memory.
Kanna listened in shock, her old heart beating faster than it had in years. "You killed the immortal lion, and the Moon Spirit granted you waterbending!"
"Whoa, calm down, Gran Gran. That much excitement isn't good for your heart," he said, worried.
"That doesn't matter, Sokka. You will be the new Chief of the tribe!"
The tan-skinned young man widened his eyes in surprise and successfully held back a grin. "But Dad is the tribal chief, and I'm too young."
"Your father hasn't been around for years, and we've had no word from him."
"But still, if he comes back, I doubt he'll agree with that decision. And like I said, I'm still young." Sokka responded carefully.
"That doesn't matter. In my long life, I've seen many chiefs—older and wiser than you—but none of them achieved as much progress as you," Kanna said proudly.
"Well, I didn't expect them to make me chief so quickly, but this works. With this, they'll have to follow me and accept the changes without complaining."
"All right, Gran Gran... but only if the others agree," he said, pretending to sound reluctant.
Without waiting for a response, he left the chief's office, which had remained vacant for years.
When he got home, he took a quick cold shower and put on a new coat. Then he went out to look for Katara—it was time for her training.
For the past few months, he'd been training his sister's body. He was worried that in the series, she wasn't very strong or agile without her water bending, so he taught her some hand-to-hand combat.
"Don't run, brat!" he yelled as he saw her walking away.
"Leave me alone! I don't want dumb training from someone even dumber!"
A vein bulged on Sokka's forehead at her words. "You're the dumb one for not understanding how important this is! Besides, Tiga's coming too," he added, hoping to persuade her.
"I don't care!"
"Ugh. What if I teach you water bending?"
At those words, Katara stopped in her tracks, turning to her brother suspiciously. "And what would you know about water bending?" she asked, eyes narrowing.
"Hm... who knows?" he said with fake indifference. "Maybe your brother's so cool that the spirits gave him the power of magical water."

"I don't believe you—and it's not magical water!"
"I'm not lying. That's why my hair is white—it's the proof. It also tells me how long I have left to use the magical water."
Katara grew more annoyed at the way her brother referred to the ancient art of water bending, but she finally agreed to train with him.
After that, Sokka picked up Tiga. The only reason he trained her was because she was young. At first, all the women in the village looked incredibly old due to poor nutrition and stress.
It was amazing how much people could change with just a balanced diet. Just look at Tiga—she looked ten years younger.
Sokka took advantage of that and convinced her to train with him a year ago. His plan was for her to be in charge while he was away with Aang, and for that, she needed to be strong. He gradually prepared her for the role—teaching her to read and write, cook, sew, and occasionally hunt with him.
They say that to make your idea a reality, you first need people to believe it was their idea. Slowly, he made the women of the village believe that Tiga was the perfect second-in-command—or something close. Just like he made Kanna think that making him chief was her idea.
"Tiga, do you think I could get the lion's skull when you're done?"
"Huh? I guess so, but why?"
"He wants it for his dumb trophy wall," Katara interrupted mockingly.
"You haven't even seen it to say it's dumb."
"No need to. Obviously, you just need the skulls of wild polar bear dogs and leopard caribou."
Sokka simply ignored his sister and then proceeded to start the training.
For several hours, he had them train in cardio and hand-to-hand combat. Without them realizing it, he taught them how to strike vital points in the body—nerves, organs, temples, and more.
At that moment, Katara and Tiga were training in combat against each other. The adult woman launched fast, precise attacks while Katara struggled to block and counter.
Sokka had designed this training specifically so that his sister would learn to counter people with that fighting style—like Ty Lee.
"My trophy wall isn't dumb, right Scar?" Sokka asked a polar bear dog, who simply looked at him and then went back to ignoring him.
Sokka huffed and began to play with a piece of cloth and his chi, seemingly unaware of his sister's training.
