"You… I'm not the last airbender?" Aang questioned, peering up at the older boy. He wiped his eyes as tears pooled, his heart racing as he blinked. Katara, Sokka and Toph all stared at the boy too though Aang was paying attention to only Harry. Harry was wearing Air Nomad clothing, an orange sash of clothing running diagonal over a red and yellow shirt. There was no arrow tattoo on the boy's head, a head of wild, black hair covering his scalp. Harry's eyes were grey, mirroring most of the Air Nomads Aang remembered, but they had a distinct greenish twinkle to them. "You can really airbend?"

Haran, or Harry as he said to call him, nodded and held up his hands, moving them in a spiral movement. Cool air flowed through the small alleyway in Ba Sing Se and Aang let out a strangled cry, closing the distance between him and the boy and burrowing into the boy's hurriedly outstretched arms.

Aang's heart beat wildly and fast as Harry's arms wrapped around him, holding him tight.

"I feel like I know you already," Harry whispered lightly.

"You're not alone anymore."

Tears fell on his cheeks and he felt Harry rubbing soothing circles on his back. Appa rumbled happily deep in his throat and Aang smiled. "I thought I was alone. How… How can this be?"

Harry pulled back a little and looked him over, his eyes narrowed in thought. "I don't rightly know. I… It's a long story."

"Well, why don't we go back to our place? We're in the middle of the Inner Circle and it's creeping me out," Sokka suggested. "Besides, what was Long Feng doing here?"

"Long Feng," Aang muttered, pulling away from Harry and walking over to hug Appa again. "He must have taken Appa!"

"I don't… think so," Harry offered, taking a step back and shrugging. "He said something about having plans. He didn't see me on Appa's back so he didn't feel the need for secrecy. But yeah, that was his intention, to take Appa."

"How come he couldn't see you? We can see you."

"I can't see him! Another version of Twinkle Toes. Ahh, man."

"Toph! He's another airbender!"

"I know that! You're too quiet is what you are."

"Come on, you guys. I'm Katara and this is my brother Sokka by the way. Let's get back to our home for now," Katara spoke, looking at Harry and crossing her arms. "Did Long Feng say anything else about these 'plans'?"

"No. He did look like he knew who Appa was and he tricked your bison. He had a whistle shaped like a bison."

Aang's eyes narrowed and a slight glow entered his eyes. Harry raised an eyebrow at him and then nodded. "Whatever he's up to, we'll find out."

"Meet you back at our house," Aang said, shaking out his glider and jumping into the air. "Do you have a glider?"

"Kind of. It's something of mine that turned into a glider a few years ago," Harry explained, bringing out a piece of wood from a pocket and twisting it in a simple upward motion. Aang watched as the stick transformed right in front of his eyes into a glider, the green fabric matching the hint of green in Harry's eyes.

Sokka's eyes widened and Katara raised an eyebrow.

"Whoa. That's so cool! It shrinks!" Sokka exclaimed, turning to Aang and gesturing to Harry's glider. "Can yours do that?"

Aang grinned but shook his head.

"Handy," Sokka remarked, his eyes narrowing. "Can I look at it when we get back?"

"Sure. I don't think… you'll find anything though."

"Momo! Appa!" Aang shook out his own glider and jumped into the air, bending the air currents around him and rose above the homes of the capital of the Earth Kingdom. Toph, Katara and Sokka all clambered up onto Appa's back, gripping onto the bison's fur, and Aang watched as his companion roared again, this time joyful, loud, and rose into the air alongside Aang. Momo made some excited chittering noises and followed them, clearly glad to have his friend back again.

Aang smiled widely as Harry joined him in the air, slipping into the air current, and flying right next to him. His heart pounded within his chest at the thought of another airbender, a new Air Nomad and he grinned wider. He wasn't the last airbender! There was someone to stand next to him, someone who knew what air bending truly was.

Appa roared out over the city of Ba Sing Se and circled around them, his dark eyes glinting in the moonlight. They flew back to where they had been given a home in the Inner Circle, only a few minutes away from where Aang had heard Appa roar, and circled into land in front of the house.

Appa landed first and Harry and Aang followed.

"Aang, this is for you," Harry offered, floating down from Appa's back with a tightly rolled piece of parchment in his hands. "We just left the Eastern Air Temple and there's a guru there, named Pathik. He says he can help you control the Avatar State."

Aang's eyes widened and he turned to look at Katara, who raised an eyebrow.

"How do we know we can trust you?" Katara questioned, as Toph and Sokka slipped off of Appa's back and joined them. "You just… appeared out of nowhere."

"I can give you an oath," Harry offered, shrugging, as he followed them into the house. "Teo trusted me back at the Northern Air Temple and I'm pretty sure Appa trusts me."

Appa stuck his head in through the door and gave him a lick, as if to emphasize the words. Harry's nose wrinkled and he wiped the bison slobber off but the smile on his face said he wasn't annoyed at all. Aang grinned and turned to Katara, gesturing at Appa.

"Appa trusts him. He's a good judge of character, Katara. And he's an airbender," Aang said. "We can trust him."

"Oath?" Toph echoed, walking over to sit down on one of the cushions that they had found in one of the rooms. They all joined her, sitting down in a circle to talk. Appa stayed outside, poking his head in through the windows to keep an eye on them. "What kind of an oath?"

"I… I suppose an oath by words," Harry tried, lifting his shoulders in a minute shrug and joining them. "Us airbenders need to stick together."

"Not to mention the fact that Long Feng probably has ulterior motives," Sokka muttered, pushing a hair behind his ear and back up into its tie. "He clearly wanted Appa for something."

"Who is Long Feng anyway? Does he work for the Earth Kingdom's king?" Harry questioned, looking between the three of them. "He honestly looked like a bad guy to me."

Aang and Toph laughed.

"He's the king's advisor," Aang said, tilting his head in thought. "Sokka, you said you'd been trying to get into see the Earth King. What's the latest update?"

Sokka scowled, shaking his head. "The king's PR person said it would take another month. We don't have another month. The eclipse is in two weeks."

"Why don't we try to see the king now?" Aang asked, looking between his friends and Harry. "We have Appa back. No one would stop us from going in when we have Appa."

Harry grinned a little. "That's certainly true. I saw Appa when he was… hurt. No one wants a feral sky bison on their tail."

Aang grimaced, turning to look at Appa. "I wonder where he was, after he was…"

"Aang, there's no use thinking about what if's," Katara said, sighing and turning to look at Harry. "I suppose it would be good to see the king as soon as possible. We don't have a lot of time before the eclipse anyway."

"Is the eclipse special?" Harry questioned, looking at Sokka and Aang. "I just thought that eclipses were just the moon moving over the sun."

"Firebenders lose their bending during eclipses," Sokka explained, pulling out his boomerang and using it to scratch his back. "Oh, you haven't… You probably don't know about Aang's time limit. We should fill you in if you're joining Team Avatar."

Harry's lips twitched up into a small grin as he nodded. "What time limit?"

"I have to defeat the Fire Lord before the end of summer," Aang offered quietly, his shoulders curling inward and pulling his legs into his chest. "And I have to learn firebending before then. Somehow."

Harry's eyes widened as he met Sokka and Katara's grim eyes. Toph was grimacing and Harry turned back to look at Aang, raising an eyebrow. "The Fire Lord's going to do something at the end of summer, isn't he?"

"Sozin's comet is coming back at the end of summer," Sokka replied, shrugging. "So no pressure!"

Toph snorted and Harry blinked, looking between Sokka, Aang and Katara. "Sozin's comet?"

"It enhances the bending of every fire bender," Aang answered, his face going pale as he met Harry's eyes. "And Ozai is going to complete his invasion."

Harry's stomach roiled at Aang's words and he went pale, dropping his arms to his sides from where they had been on his lap. "That… sucks."

"Yeah," Aang said, propping his chin on his knees.

"I see why the eclipse could come in handy then," Harry finally said, peering up and throughout a window to look out to where the Earth King's palace was. "You want to invade the Fire Nation on the day of the comet."

"Everyone's been keeping us away from the Earth King too," Sokka said, frowning in thought. "And everyone's been acting weird in the city too. No one talks about the war that's going on outside of the walls."

"Well, no time like the present," Harry offered, gesturing to where the palace was. They could only see the hundreds of torches around the palace but they knew it was there, a big, tribute to the Earth Kingdom's monarch. He played with the Elder Wand in his lap, rolled up the cloak and tucked it into a pocket. The ring was still in his hidden bag as Harry didn't quite want to draw that much attention to himself. "If the eclipse is in two weeks…"

Aang nodded, yawned and then stood up. "I know we're all tired but now is as good as any time to force our way into the palace."

Sokka dipped his head in agreement. "Long Feng certainly wouldn't be expecting us so soon after getting Appa back. Let's do it."

Katara nodded as she stood up, reaching out a hand to help Toph up. "Alright. We're doing this then."

Appa roared and Harry followed the others outside the house, watching as Aang floated up onto Appa's back. Toph bended the earth underneath her and had it push her up onto Appa's back while Katara and Sokka ran up Appa's tail. The bison didn't seem to care how people got up onto his back so Harry copied Aang, moving his hands around and let the air carry him up.

Aang grinned at him as Harry gripped onto Appa's fur tightly. "How did you learn how to bend in the first place? Everyone that I knew and grew up with had to learn the bending moves. You just seem to do it naturally."

"I… learned a few moves from what scrolls I could find," Harry explained, shrugging and ducking down into Appa's fur. "I have them in my bag if you want to look at them but then again… You are the Avatar and you grew up an air nomad. For the other moves… I was taught by the last Air Nomad to become an Avatar."

Aang blinked and stared at him. "Yang-chen. She's dead though."

"She is. I talked with her in the spirit world."

"In the…" Aang trailed off, his eyes going wider. "You've gone to the spirit world?"

"I… Later. We'll talk later, alright?" Harry tried, seeing Sokka, Katara and Toph stare at him too. "I would prefer to tell you guys in privacy."

Aang nodded and called out to Appa to take off. "Yip yip!"

Appa groaned and slapped his tail against the stone ground, lifting off into the air. Harry grinned as air curled around them, the slight breeze of the night growing increasingly cooler. Toph had a white knuckled grip on Appa's fur while Katara and Sokka had ducked down into the bison's fur too.

They flew over the city and Harry stretched out with his senses, hoping to get some clue as to where that firebender was. His mate… He wrinkled his nose at the thought. His mate was a firebender. Though… it wasn't like he could sense a lot of firebenders in the capital and that drill outside by the gate had looked defeated. Perhaps it was a soldier from the Fire Nation that the Earth Kingdom police had taken prisoner.

"Hey, when you guys defeated that drill," Harry started, raising his voice to be heard over the wind and looking at Katara.

"Yeah, we did that," Sokka replied, raising an eyebrow. "Why?"

"Did you take any prisoners?" Harry asked, looking between Toph, Katara and Sokka.

Katara blinked but shook her head. "No! The Fire Nation soldiers all died while we stopped the drill and Princess Azula and her team escaped!"

Harry nodded in reply. "Azula is…"

Sokka grimaced and Aang turned around from where he sat on Appa's head.

"Azula is Ozai's daughter," Sokka said, also raising his voice as they gained on the palace. "She's been after us for a few months! Ty Lee and Mai are non benders but you still need to look out for them!"

Katara scowled and her eyes widened a little, perhaps in worry. "Ty Lee does something with her hands when she touches benders so don't let her touch you when we encounter them again. She… restricts or temporarily takes your bending away. You'll know her when you see her."

"Got it. Don't let Ty Lee get within touching distance. I presume Azula's a bender?"

Aang nodded. "She's better than Zuko. She used blue fire when we last fought her!"

"Blue fire! Is that something… worse than just regular fire bending?"

"More intense, sure!"

"Guys! We're here!" Aang exclaimed, pointing down to the beginnings of palace courtyard. The big behemoth of a palace was on the top of a hill and there were many Earth Kingdom soldiers between them and the palace but that wasn't about to stop them. One of the soldiers catapulted a big rock straight up at Appa and Aang flew off and cut it in half with a stroke of earth bending.

Harry grinned and then drew out the elder wand, seeing it shift into a glider out of the corner of his eye, and took off, bending the air under him to sweep three soldiers off their feet. He could see Katara bending the water in the moat that lay around the palace into a big enough wave to crash into more soldiers and Toph bending stone into bowling balls and throwing them into the path of the mounted soldiers.

Harry hovered in the air briefly, watching as Katara bent the water into ice and trapped most of the soldiers. His heart began to race at the sight and he looked at her in awe before a boulder came right at him. He sped away, bending the air around him in a circle and racing straight towards the man who had sent it his way, moving his hands in a circle and drawing the air close, creating a funnel of air and swept the man away into the moat a few feet back.

He flew back to Appa, hovering next to the bison as Aang and Toph bent the stone underneath Appa to slide up the hill to the palace. Sokka threw his boomerang at a soldier who had gotten within their circle, calling out an apology to the guy when the boomerang knocked him off.

"We're not mad with you! We just want the Earth King!"

Harry snorted and swept another two soldiers off their feet, pushing well away from Appa. Within a minute, they had arrived at the top of the courtyard and right at the great door to the palace. Harry swung through the air and bent a circle of air in tight and lobbed it a palace soldier, hitting him and knocking him off and up into the air.

Sokka slid off from Appa's back and led the way, his boomerang having returned and raised in his hands. Aang, Katara and Toph went next and Harry circled into land and followed, willing his wand to shift back and then tucking it in a pocket. He glanced into an open room, poking his head into check and called out that it was clear, scaring a noble lady into hiding under the bed. He could hear screams throughout the palace and watched as Sokka did the same, closing one door very quickly and coming out with a reddened face.

Harry grinned as they made it to a great entry hall, tossing away any soldiers that came at them. Toph laid her hands on the floor of the hall, moving her feet in a bending stance and muttered under her breath.

"The Earth King's that way!" Toph exclaimed, pointing to the north of the palace. "Let's go!"

Appa took up the rear, growling loudly in his throat, and roared as soon as they came to a really heavy looking door.

"That one's obviously where the king is," Katara muttered.

Appa again roared out and charged the door, breaking it down as he collided with the stone. With a large crash, the great door to the throne room fell. Ash and little bits of stone covered the entryway and they all jumped over the remains of the door.

They all ran right up to the throne and stopped, with each bender having a little bit of their element in front of them. Katara had a stream of water hovering between her hands. Toph had a small boulder in front of her. Aang had a pillow of air between his fingers and Harry crossed his arms behind them, his eyes glowing dark for a second or two as they looked up to the Earth King.
