This is somewhat AU. Assume everything in the show happened until after the fall of Ba Sing Se, but I added new scenes before the fall, which explains why the Day of the Black Sun invasion is different, as well as everything afterwards.

Azula groaned. She just wanted to leave. Ty Lee convinced her to go to the royal doctor after puking for three days straight.

"It was probably bad ramen," Azula said.

"But Mai and I had the ramen, and we didn't get sick."

Azula frowned. "Maybe my immune system is weaker."

"You never call yourself weak."

Azula rolled her eyes.

The doctor was ready for her. "Do you have any symptoms other than vomiting?" he asked her.

Azula thought for a moment. "Well, I've been getting tired more easily."

"And are your cycles regular?" he asked.

Azula frowned. "I missed one a few weeks ago, but that's normal at my age, right?"

"It is but …"

Ty Lee's eyes got huge. She knew what he was implying. "Azula, have you had sex in the last two months."

Only once, Azula thought. "Why?"

The doctor and the acrobat looked at each other. Neither of them was willing to say what was starting to become evident. Finally, Ty Lee suggested, "Maybe you're pregnant."

Azula looked appalled. "I can't be pregnant!" Ozai will kill her.

"So you used protection?" Maybe it's a fluke.

Azula frowned. "I meant to get some tea the next day, but I think I forgot." Azula tried to think back to that morning, but she couldn't remember drinking it. DAMN!

The doctor gulped. "Maybe we should just keep this to ourselves and hope it's a false alarm." He knew how Ozai would react. They all knew.

Azula got up. "This can't be happening." She ran off before Ty Lee could stop her.

Unsure of what to do, the chi blocker went to ask Lo and Li for help.

The two sisters were sharing a cup of tea when she found them.

"Ty Lee, what brings you here?" Lo asked, or was it Li?

"I came to see if Azula was better."

"She was sick?"

"She's been vomiting lately."

"Well, I hope it's nothing serious."

They saw Ty Lee frown.

"She isn't ill, is she?"

"Ill isn't exactly the correct word."

Lo and Li looked at each other. They had seen this in the trade many times. Their princess was pregnant, and if she didn't get out of here, she would be in grave danger.

"We should prepare their vacation house at Ember Island," Li finally said.

Lo nodded. "We must get her out of the palace before it's more evident."

The Gaang was getting ready to invade the Fire Nation. The Mechanist had made them submarines and weapons, so they could attack the Palace.

Sokka was ecstatic. He had maps and plans and he would finally be able to prove he was more than just the non-bending lackey.

"We move in three days time," Sokka told them.

Katara was nervous. Last time they fought the Fire Nation, Azula killed Aang, and this time, Katara had no spirit water to revive him.

Toph was ready to knock heads. "A princess without her bending, not too scary!"

Aang was just hoping they got the timing right. If they went too early or too late, it would be for naught. It might even ruin their war efforts all together.

"Toph, ready to train?"

"You mean am I ready to kick your tiny butt. Yeah let's do it."

Zuko was so confused. He had everything he was supposed to want, first in line to the throne, he was back with Mai, but without his uncle, it just felt hollow. Did he make a mistake in joining his sister? She had never really invited him into anything before. It had always been her and Ozai, Zuko and Ursa.

He went to talk to her. He hadn't seen her in a few days.

"Did you come here to gloat?" she frowned.

"Gloat about what?"

He didn't know. "Never mind."

"Is something wrong?"

"No. I'm just as happy as a turtle crab," she said dryly.

Zuko could never tell what was in her head. "Do you think Mom is still alive?" As soon as the question came out of his mouth, he wondered why he had asked her. How would she know and even if she did, why would she tell him the truth? She always lies.

Azula shrugged. "I have no idea," she said honestly. She knew her disappearance was connected to Azulon's death and Ozai skipping over Iroh for the throne, but she wasn't sure exactly what happened. Ozai had been ready to kill Zuko, but then he didn't. Maybe Azulon banished Ursa instead as a way to punish Ozai. That didn't seem quite right, but she wasn't sure. "Why now?"

"What?"

"She's been gone for almost six years. Why ask me now?"

Because if she were here, she would tell me what to do. "I don't know. Doesn't it bother you that she never said where she was going or why?"

"Maybe she didn't want us to find her."

"You can't think that!"

"Maybe she thought Ozai would follow us to get to her."

Zuko frowned. That actually did make sense. "Do you think we'll ever find out what happened to her?"

Azula frowned. "I don't know if Ozai will ever tell us. Maybe there's another way." Excuse me, Azula left to go hurl.

"She never gets sick," Zuko said to himself. "How odd?"

Azula came back. "As you can tell, I'm not well."

"Are you like really sick or …?"

"Just food poisoning. You won't get rid of me that fast."

"Well whatever you ate, I don't want to eat it."

"Don't go to Ming's ramen house."

"I never liked that place anyway."

"Of course. You don't like food with flavor."

Zuko rolled his eyes.

Day of the Black Sun

The submarines were on the move. Sokka was leading the charge into the Fire Nation.

When they got to shore, however, they found that their vessels were under attack. Qin had developed a counterattack for the invaders.

"We're screwed," Hakoda realized. He looked to his son. "This is your invasion. What do we do?"

Sokka had to decide right now. "Forge ahead. We have to hope for the best." If they surrender now, they're screwed anyway. They may as well try to take out Ozai now.

They stormed the palace. Aang and Katara kissed before they went their separate ways.

Sokka, Aang and Toph found the bunker to see Azula sitting in a throne. She looked pissed off, like she didn't want to be there.

"Where's the Loser Lord?" Toph hissed at her.

"What?" Azula looked like she hadn't even been listening.

"Ozai, where is he?"

"Obviously not in here." She didn't get up out of her chair.

Sokka drew his sword. "You don't have your bending right now. You best cooperate."

"Why? Aang is a pacifist. He won't let you kill me."

Aang frowned. She had a point. Then he got pissed off. "It doesn't mean we won't harm you."

He had his fists raised.

"Go ahead and try."

He took a swing at her, but he missed. Even pregnant, she was still very quick. He went back and forth, but he couldn't seem to land one blow.

Toph frowned. She felt a fifth heartbeat. "Who else is in here?"

Sokka looked at her. "What? It's just us against Azula."

Toph frowned. "I feel five heartbeats," but she couldn't feel anyone hiding. That only made sense if, "you're pregnant!"

"Shh!" Azula hissed. "If my father hears you, he'll kill me."

Sokka made a face. Who the hell would sleep with her?

"Who's the father?" Aang asked her.

"That's none of your business!"

The time was dwindling. Azula knew they would never get to her father in time. "You best run, before the guards come back."

"Why should we listen to you?" Toph hissed.

"Because you're running out of time. I have nothing to gain by your capture."

"You don't?"

"If Ozai wins, I die. If you win, I get put to death for war crimes. It makes no difference to me whether or not you win, but it makes a difference to you, so get out of here."

Toph could feel the guards approach. "They are coming. We gotta go."

Aang felt bad. Azula might die because she was having a child.

"Come on!" Sokka grabbed him and they ran.

While they were leaving, Zuko was preparing his war balloon. He had to get out of here before Ozai had him declared a traitor. He only hoped the Avatar would accept his help after what he had done.

He felt bad breaking up with Mai in a note, but he had no time to explain. He just had to go.

The rebellious prince took off for the skies, hoping this somehow all panned out in the end.

Western Air Temple

Sokka buried his head in his hands. His invasion was a total disaster. His father and his men were captured. They never even saw Ozai. Azula was even too apathetic to fight them.

"We couldn't get past a pregnant teenager who didn't bother to throw a punch."

Aang frowned. "Should we have taken her with us?"

"Are you mad? Why would we do that?"

"Because she's pregnant."

Sokka hadn't really thought of the baby as a person yet. "Maybe her dad won't be that mad."

"Are you nuts?" Toph said. "She's as good as dead. He burnt off his son's face for speaking out of turn. Being knocked up is like 10 times worse than that."

Sokka gulped. "Why didn't you say that before?"

"We were running for our lives, Snoozles!"

"Oh yeah. She's resourceful. Maybe she'll just run away."

Toph frowned. "Now that you mention it, we could have used a firebending teacher for you."

Sokka shook his head. "So there was a way to make the invasion not totally fail and I botched that too!"

Out of no where, a bomb went off.

"WE'RE UNDER ATTACK!" Katara screamed.

Combustion man had arrived. They were about to get a healthy dose of danger.

The group started to run. "What the heck is that thing?" Sokka yelled.

"My guess is a hit man," Toph retorted.

"Who would send a hit man?" Aang questioned.

"Take a guess," Toph snapped.

"Ozai?"

"Or one of his children," Katara said.

"Damn it!" Sokka yelled. "Why can't anything go right around here?"

Zuko landed his war balloon and found the group running. "Let me join you!"

"Who's that?" Aang questioned, not seeing anyone.

"It's Zuko!" Toph told him.

"Hell no!" Katara yelled at him. "You got Aang killed."

"I'm sorry okay! I can teach him how to firebend."

"Can you get this hit man to leave us alone?" Sokka questioned.

Zuko tried to negotiate with the man he hired only to get attacked. He had to sprint away. The man had burned off his shirt. "I tried to call him off, but he wouldn't listen."

"YOU HIRED HIM!" Katara yelled.

"OOPS!" Zuko should have said Azula hired him. Damn it!

The royal doctor suggested to Ozai that Azula go to Ember Island to recover.

"Recover from what?"

"She got a nasty infection. It's passed through on its own, but she's weak still. I think some fresh hair and sun would do her some good."

"Whatever." One kid was a traitor, the other was a weakling and she lied to him. She would be punished once she was better.

Lo and Li took her to the family vacation house.

"What am I going to do? Hide here until I give birth?"

Lo and Li didn't know what came next. "Hopefully, we can get you out of here before you start showing."

Azula groaned. Zuko fled and now she's fleeing, so much for the great line of Sozin! "I just need to lie down."

When she closed her eyes, she would hear his voice and feel his hands on her skin. She couldn't forget the night that caused this whole mess, and she wished she could. "One night of foolishness will cost me my crown, probably my life." For the princess who was always in control, this was unfathomable.

Zuko tried to prove his loyalty by taking on Combustion Man by himself, but he was not faring so well.

His firebending was weak for some reason. He couldn't seem to fuel it.

Eventually, Toph aided him, launching boulders at the assassin. He started to stumble. Sokka threw his boomerang, knocking him off the temple, presumably killing him.

Zuko collapsed on the ground in exhaustion. "Finally!"

The four had to decide what to do with him.

"We can't trust him," Katara insisted. "He's the one who almost got us killed in the first place."

"But he tried to make up for it," Toph said. "Even if his firebending sucked."

Sokka frowned. "Will he make much of a teacher?"

Aang decided to give Zuko a chance. He regretted not trying to help Azula. Maybe if he helped Zuko, they could go back for her.

Katara's words were harsh. "If you betray us again, it will cost you your life."

Zuko gulped. Accepted but not quite, Zuko would have to take it.

Ty Lee and Mai went to join Azula in the vacation house. Mai still couldn't believe she got pregnant. "No offense, but I figured you would have been the teen pregnancy case," Mai said to Ty Lee.

Ty Lee shrugged. "Me too. I had a couple of scares in the circus."

"Did she tell you …?"

"No. She won't talk about that night or him."

"Was she …?"

"She said she wasn't." Who knows if this is true?

"You don't think it's (Ozai's)?"

"I hope not!"

Azula started to stir.

Mai was cutting the pits out of Azula's cherries. It was one of the few foods she could keep down. "How long can we get away with hiding out here?"

"I'm not sure. We should probably try to leave before her second trimester starts."

"When is that?"

"I think in six weeks."

Mai had some distant cousins who might take in a knocked up Princess. "I have some letters to write."

Over the next week, Zuko tried to get his firebending back. "My source is gone."

"You're what?" Aang questioned.

"Firebending is derived from within, unlike the other elements. You need both good breath and a source, a spark, something to get you excited. I used to use my anger to fuel me, but now that I left my father, I don't have the anger. I don't have anything to generate my bending."

"So your jerkbending failed when you stopped being a jerk," Sokka quipped.

"Maybe you should try the first firebenders," Toph suggested. "I learned from the badger moles."

"The sky bison are the first airbenders. Maybe I could learn from you Appa," Aang said.

"There are no more dragons," Zuko said sadly.

"But when I was a kid, there were plenty of …"

"THEY'RE ALL DEAD!" Zuko snapped. "Iroh killed the last one."

Toph frowned. "Maybe you could try the Sun Warrior's temple. The ruins might have something."

The two boys went there and Aang almost lost his foot in a trap.

"You set of traps easily, don't you," Zuko teased.

They got the top. "I cant' wait until the solstice!"

Zuko reflected the light with his sword. They got inside and saw the statues depicting the dancing dragon.

"I think we're supposed to do this dance together," Aang told him.

Zuko frowned, but he tried it. They met in the middle and the sun warrior appeared. "Who are you and why did you come here?"

"I'm the Avatar."

"And I'm Prince Zuko."

"We wanted to learn the true meaning of firebending."

"Well, maybe the dragons will teach you."

He took them to Ran and Shao and the dragons looked at them before starting their dance.

Both men were taken aback by the beautiful show.

Afterwards, Zuko tried to produce a flame. "It's back!"

"Let's go!"

On the way back, Aang asked Zuko about his sister. "Are you worried about her?"

"Why would I worry about her?"

"Ozai must be mad."

"Because I defected?"

"Because she's pregnant," Aang told him.

"WHAT?" Zuko screamed. "She can't be!" He thought she was a lesbian.

"Toph felt a second heartbeat."

Zuko frowned. Was it Ozai's? He couldn't imagine she willingly had sex. "This sounds awful, but for her sake, I hope she miscarries."

Aang gulped. They had to try to help her.

One week later

Sokka, however, had a different rescue mission planned. "We have to go to Boiling Rock and get Dad."

"No one's ever escaped from it before," Zuko cautioned.

"So you won't go."

"I'll go. I'm just letting you know it's not going to be a cake walk."

The two boys took off for the isolated prison. They ambushed two guards and got their uniforms, which worked until Sokka found Suki.

Zuko tried to keep a guard from seeing them and he got caught.

Ozai was furious. He demanded Azula go kill her brother.

Azula read the summons. "We have to go deal with Zuzu."

"What?" Mai questioned.

"His dumb ass got caught trying to stage a prison break."

Mai's face fell.

Azula was holding Zuko's death warrant in her hands.

The three girls went to the prison, not speaking much at all.

Azula didn't want to kill her brother. Normally, she wouldn't care about death, but ever since she found out she was pregnant, the war started to feel repulsive, like it was bad for her baby or something.

"Do babies make you weak?" She asked her friends.

"What?" Mai was baffled by the question. "Well, you probably won't fight as well pregnant, but I think you knew that."

"I meant my willpower. It's like my thoughts are changing now."

Ty Lee shrugged. "It might be the hormones."

"This really sucks!"

Mai couldn't disagree.

Zuko found himself alone in a cell. This can't get much worse, he realized, until a stiletto went right in front of his face and into the wall.

"That was a good one," he said weakly.

"How, I missed?" Mai stared at him, holding the letter he had sent her. He had a lot of explaining to do.

Azula frowned. "How long does she need to yell at him?" Azula wanted to throw a lightening bolt in him and get the hell out of there. Maybe she should steal Zuko's war balloon and run away, that sounded really good right now. Actually, if she ran away, she wouldn't even have to bother to kill him.

"Ty Lee, let's go."

Before the chi blocker could ask where, Azula ran to the top of the prison. She saw Sokka and his comrades getting into the ship.

"Not so fast," She said.

Sokka freaked. "We gotta go."

"And leave Zuko?" Suki frowned.

"If we don't go now, we'll be dead and thus, we'll leave Zuko anyway."

Azula said, "take me with you."

"WHAT?" Sokka yelled. "No way!"

"Take me with you or I'm cutting the rope!"

Sokka frowned. "Fine!"

Azula jumped on board. Ty Lee followed her.

Mai understood why Zuko left. "You should have told me."

"I didn't have time."

"You had weeks to wonder if you should have sided with your uncle and you didn't even mention it to me."

Oh that. "I'm sorry, but …" The alarm went off.

They ran to the top of the prison to see the warden taken hostage.

"CUT THE ROPE!" He yelled to his niece.

Azula yelled, "Don't you dare."

"Why is she on board?" Zuko questioned.

Mai jumped on the ship. "Let's go."

Katara and the others anxiously awaited their return. "I hope Sokka didn't get himself captured," or worse killed.

When they saw a war balloon, they were relieved until Azula got out. "You suck at landing," she yelled at her brother. His crash made her want to puke.

"The balloon was overweight by like four people."

Azula threw up. "Sure, blame the passengers. You're a terrible captain!"

Katara frowned. "What is SHE doing here?"

Azula grinned. "Nice to see you too, Peasant!"

"YOU LITTLE!" She charged at Azula only to get grabbed by Aang.

"She's pregnant. You can't fight her."

"See, Peasant!"

Aang frowned at her. "All that negativity isn't good for the baby."

"What do you know? You've never had a baby."

"My past lives have. That counts!"

"Does not!" All of the girls yelled at him.

Suki still couldn't believe this all. "Who's the father?" she asked her boyfriend.

"No one knows."

Needless to say, Ozai wasn't amused when he learned his daughter and her friends had run away with Zuko and his posse. "What the hell is wrong with her?" Ozai snapped. He never should have let her go to Ember Island. He never should have sent her to capture her brother. He should have kept her at home, where she couldn't cause any trouble where she was only his.

Azula left almost as quickly as Zuko did. Was this the plan? Were they running away together all along?

Ozai needed answers and he ordered the royal doctor to his office.

The man was a nervous wreck. He knew Ozai suspected something, but what did he think. The doctor took a puff of opium to calm himself before facing the vicious Fire Lord.

"Doctor."

"My Lord," he bowed.

"What was wrong with Azula?"

"She was vomiting repeatedly. She thought it was bad ramen, but I contacted the restaurant and there had been no complaints. There was a flu going around, so I assumed she caught it."

"And how long does it take to recover from the flu?"

"It can take a week. A week past, and Azula seemed lethargic, so I suggested a few days on the beach so she could get some air."

"Well, she got some air," Ozai said, before he threw a fire whip directly at the man. "And then she flew out the fucking nest!"

The room smelled of burning flesh as the fire whip got the doctor's arm. "My apologies, my Lord."

The doctor didn't seem to know anything. "Get out of here!"

The man ran to tend to his wound.

Ozai called for Lo and Li, but they split as soon as they got Azula to Ember Island. They knew once Ozai found out, he would want their heads.

"Those old hags fled." Ozai started to wonder why he had hired them in the first place.
