Kairi laid back down on the snowy ground and closed her blue-grey eyes. She breathes heavily and felt the air surrounding her. She felt the air push her up, and she regains balance. She looks down at her right leg and uses the air within her body to give her the strength to walk. She looks forward and begins to walk toward her siblings.

" Sokka! Katara!" Kairi shouts.

Kairi stood beside her siblings and looked down at them. She saw Sokka let go of Katara, and their younger sister rolled to the side. She grabbed her brother's hand and used her strength to pull him up.

" Are you okay?" Kairi asked while looking at Sokka from head to toe.

" I'm fine. I think I hurt my back a bit," Sokka rubbed his back.

" Can I?" Kairi asked.

" Sure," Sokka nodded.

Kairi walked behind Sokka and hugged him from behind. She then used her strength to lift him up and carefully cracked his back.

" Ooh. Much better," Sokka shivered, feeling his whole body relieved.

Kairi let go of Sokka, and she smiled at him. She turns to Katara and holds her hand out to her younger sister.

Katara looks at Kairi's hand and then looks past her older sister. Her blue eyes widened when she saw the boy on top of the ice. She gasped, grabbing Kairi and Sokka's attention.

Kairi and Sokka turned and saw the boy on top of the ice. Sokka grabbed the wooden club from the icy ground and tightly grasped it.

Kairi stared at the boy with mixed emotions since his clothing seemed familiar. Her blue-grey eyes widened when she saw the lights vanish, revealing the color of the clothes.

' Red and yellow! It's the same colors of the clothes that Great-Grandpa wore that Gran Gran lets me wear when I train my air bending,' Kairi internally speaks. ' I cannot believe it! He's an Air bender like me,' She watched the boy fall forward.

Not wanting the boy to get hurt, Kairi held her hands out and pushed a gust of air toward the boy to cushion his fall.

Sokka looked at Kairi curiously, surprised that she saved the boy with air bending. Meanwhile, Katara looked at her older sister with mixed emotions since she didn't expect her to air-bend.

' How?' Katara internally asked.

Kairi watched the air lay the boy down on the snowy ground. She walks toward the boy, causing Sokka to look at her warily.

" Kairi," Sokka hissed. " What are you doing?" He asked, looking at Kairi worryingly.

" Checking to see if this kid is alive," Kairi responded. " He looks like he's twelve," She looks at the boy.

" He's alive! He was standing on top of the ice before he fell!" Sokka remarked.

" We don't know if his adrenaline rush was keeping him alive. What if it has worn out, and he dies instantly? It's not bad to check," Kairi reasoned.

Katara stands and looks at the boy curiously.

Kairi crouches beside the boy and gently puts two fingers against his neck. Meanwhile, Sokka stood behind his younger sister with his wooden club in his grasp, ready to strike at the kid if he tried anything to them.

" Is he?" Katara asked, looking at the boy curiously.

" He's breathing. That's a good sign. It means he's alive," Kairi responded.

The boy's stomach was lying on the snowy ground, so Kairi turned him around and cradled him in her arms.

Kairi's blue-grey eyes studied the boy from head to toe. She noticed he was bald and had a blue arrow tattoo on his head that led to his back. She figured that the tattoo must be all over his body since she saw the same blue arrow tattoo on his hands that were peaking out from his arm sleeves.

Kairi hummed, remembering Kanna telling her that her father, Sora, had similar markings on his body. He explained to her at a young age that the blue arrow tattoo represented an air-bending Master.

' I cannot believe it. This kid is an air-bending Master at such a young age,' Kairi internally speaks, looking at the boy in awe.

" Ugh," The boy murmured, moving around in Kairi's embrace.

" He's waking up," Katara whispered, looking at the boy with mixed emotions.

The boy opened his eyes, revealing a dark grey color. His eyes blinked, seeing an older girl with long brown hair in a ponytail, bright blue-grey eyes, and a crescent moon shape birthmark on her right cheek, wearing Water Nation clothing, looking at him in worry.

' I made it to the North Pole,' The boy internally speaks. ' Sora said that the North Pole will take us in safely,' He looked relieved.

" Who are you?" The boy softly asked.

" My name is Kairi. The guy standing behind me is my older brother, Sokka. Don't mind him. He is just protective of us girls. The girl near us is our younger sister, Katara," Kairi introduced her and her siblings to the boy.

The boy looked at Kairi, Sokka, and Katara curiously. He noticed that they were all wearing thick clothing, which he figured since it was cold and snowing at the North Pole.

" My name is Aang. Are we perhaps at the North Pole?" The boy asked, wanting confirmation.

Kairi and Sokka looked at each other and then at Aang.

" Kid. We are at the South Pole," Sokka responded.

" So, no Northern Water Tribe?" Aang asked, looking worried. " I promised my friend I would meet him here!" He begins to panic. " He was using a glider to fly to the North Pole. Ahh! I should have let him come with me. I had my flying bison!" He babbled.

Aang used his air bending to jump, causing Kairi to look at him in awe.

" Your friend?" Katara looks at Aang.

" Flying bison?" Sokka raised an eyebrow.

Aang looked at his surroundings.

" My best friend! He's like a big brother to me. He's a couple of months older than me," Aang explained.

" What's your best friend's name?" Kairi asked, looking at Aang curiously.

Aang turns to look at Kairi.

" His name is Sora," Aang responded.

Kairi's blue-grey eyes widened.

Sokka and Katara looked at each other.

" Isn't Sora the name of our Great-Grandpa?" Sokka asked Katara.

" Yes. Sora is Gran Gran's Dad," Katara responded to Sokka.

" But How? Great-Grandpa died long ago," Sokka frowned.

Kairi's blue-grey eyes intently stared at Aang.

" I know your friend, Aang. And he didn't go to the North Pole. He came here to the South," Kairi tells Aang.

" He's here! Is he okay?" Aang asked, looking excited.

Kairi walks up to Aang.

" May I?" Kairi held her hand out to Aang.

Aang looks at Kairi's hand and nods.

Kairi grabbed Aang's hand and lightly grasped it.

" Your friend, Sora, is our Great-Grandfather," Kairi tells Aang.

Aang raised an eyebrow.

" How is Sora your Great-Grandfather when he's twelve like me?" Aang looked at Kairi and her siblings with a confused expression.

" Well. My Grandmother, Kanna, told me that her Father, Sora, came to the South Pole long ago after falling from the sky," Kairi softly tells her siblings.

Aang looked at Kairi with mixed emotions.

Sokka and Katara looked at each other worryingly.

" My Gran Gran said that her Mother, Akua, nursed Sora back to health," Kairi tells Aang.

Aang's grey eyes intently stared at Kairi's blue-grey eyes.

" Sora told my Gran Gran when she was a little girl that he searched everywhere for his best friend. He was so worried about him because his best friend was the current Avatar," Kairi squeezes Aang's hand.

Tears welled up in Aang's grey eyes when he heard that Sora had been searching for him.

" Where is he? Take me to him, Kairi." Aang's voice cracked.

Sokka and Katara frowned.

" I need to see Sora, Kairi. Please, take me to him," Aang begged.

Tears welled up in Kairi's blue-grey eyes.

" I'm so sorry, Aang. But Sora has passed away. He would have been one hundred and twelve years old today if he was alive. He died when he was seventy, forty-two years ago," Kairi confessed.

Aang's grey eyes widen when he hears that Sora has passed away.

" No. No. Sora can't be dead," Aang muttered. " He was alive when I last saw him!" His whole body begins to shake.

" Kairi," Sokka warily stared at Kairi and Aang since his sister was too close to the stranger.

" Aang. Sora loved you so much. My Gran Gran would be happy to tell you stories about him," Kairi comforts Aang and hugs him.

Aang hugs Kairi tightly.

" He can't be dead," Aang cries, denying that his best friend is gone. " Did he at least meet with other Air benders after the Fire Nation attacked us?" He asked while hiding his face against Kairi's right shoulder.

Kairi gently rubs Aang's back in a circular motion. She lets go of him and looks at him sadly.

" He has gone to all the Air Temples growing up. And when he returned to the South Pole, he told my Gran Gran that all Air Benders were gone. And since he couldn't find you. He believed that you died too, so he was the last Air Bender all his life until I was born," Kairi explained.

Aang's watery grey eyes blinked, looking at Kairi with mixed emotions.

" You can bend Air?" Aang softly asked.

Kairi nodded.

Kairi breathed in and out as she waved her hands, creating a small air ball. She knew how to do that thanks to Sora's scrolls that he passed down to Kanna.

Aang gasped, surprised to see an airball coming from a Water tribe member.

" Not only can I air bend, but I can also water bend," Kairi smiled. She glanced at a nearby water source and held her hand out to the water, watching it rise.

" Woah!" Aang looked at Kairi in awe, surprised that he had met an air bender that could bend water.

Even though Sokka doesn't trust Aang, he is glad that Kairi has met an air bender that can bend air like her. However, Katara looked at her sister and Aang with an envious expression. She didn't like that her older sister was showing-off to the cute boy.

" You should come with us to the Southern Water Tribe! Gran Gran would be delighted to know that another air Bender exists! And not only that, he is friends with her father," Kairi grabs Aang's hand and begins walking with her new friend toward her Tribe.

" Hey! We can't just bring a stranger to our Tribe!" Sokka shouts and begins to follow Kairi and Aang.

Katara silently follows Aang and her siblings. She stared at Aang's back, curious to know more about the mysterious air bender who was once best friends with her Great-Grandfather.
