They arrived at the spirit oasis once more.

"I am... a legend now! The Fire Nation will for generations tell stories about the great Zhao who darkened the moon! They will call me Zhao the Conqueror! Zhao the Moon Slayer! ZHAO THE INVINCIBLE!"

Aang stared at the admiral. Well, the knowledge he gathered from Zuko would now come in handy. Aang inhaled, gave the man an out of character deadpan stare, and spoke.

"Ok boomer." said Aang.

The world shook.

Zhao squawked, "What did you just say, boy?" The sideburned man clenched harder on the bag with the moon spirit in it, and waved his sword at the Avatar. His face was red with fury, and there was even steam coming out of his ears. "What did you say?! What is a boomer? I am a trained admiral and I will not tolerate this blatant disrespect coming from you, boy! How dare you call me a boomer?"

Sokka snorted from behind Aang, "Ok boomer."

Zhao was truly enraged now. "You peasants! Address me with respect, for I will be your new overlord when I invade this uncultured tribe and kill the moon spirit!" He stomped his foot childishly. Throwing a tantrum, Zhao screeched, "Die!'

As he was about to slice the white fish, when a most unexpected thing happened. From Zhao's back dashed Zuko with a fiery punch who decked Zhao in the face. "Vibe check!" His deep voice thundered as Zhao was pummelled into the water. In a flash, Katara froze the shocked man and he was rendered immobile. Zuko, very proud of himself, snickered at the fallen admiral. "You failed the vibe check, now prepare to die." He said, T-posing over the rightfully terrified Zhao.

Yue was the first to walk over and join him, asserting her dominance over the frozen man as she towered above him. Sokka followed her, causing Katara to shrug and join in on the T-pose circle. Aang then used an air blast to loom above the T-pose circle, he himself T-posing right above Zhao. All the Fire Nation soldiers who were with Zhao had long fled, some of them with wet pants. And Zhao had passed out.

"What in the name of Agni is going on?" Iroh gawked at the sight.

Zuko turned and waved at the familiar sight of his uncle. "Oh hi uncle, I'm a time traveller." He wondered if he should tell uncle about boba tea from the future, which had been an invention of his from the comics. Then he realised he had to explain his erratic behaviour. "The future is weird, please don't ask." He said after what was the longest staring contest in the history of staring contests.

Iroh gaped, "Why do you have the words 'That's rough buddy' on your outfit?"

"Long story…" sighed Zuko.

"And your hair?" Iroh raised an eyebrow.

Zuko face-palmed and mumbled quietly so no one else could hear, "Even I hate the season one hair…" He looked back at his uncle and coughed, "Future shit- I mean, stuff."

Aang and everyone else looked at the awkward interaction between the two and cringed. Piping up, Aang said, "I think I accidentally did some spirit thing and sent him to either the future or an alternate universe where he spent months being in… Sorry…" The airbender looked apologetic. Zuko nodded in confirmation.

Iroh squinted, "Nephew, what did you see in the future?" The ex-general was worried for both his own and his nephew's sanity. "You have changed in more ways than one."

From behind, Sokka whispered, "Yeah, he's actually not a jerk now." He glanced at the firebender and said, "He's just corrupted with weird future lingo."

Musing, Zuko replied to Iroh, "In the future, this entire thing — Like, our lives, it's all a show. When I went to the future, everyone made me watch it, so I did. Anyways, I know how the war ends, plus stuff that happens years after the war because of the sequel show. It's pretty good."

Iroh was still very confused, as none of that explained what a vibe check was.

"Look, the future is weird, that's all I'm saying. I'm getting tired of explaining this, if I act weird it's not because I'm possessed by fucking spirits, it's just future stuff." Zuko said annoyedly.

Sokka popped up and exclaimed, "Don't worry Mr. Zuko's uncle, he doesn't explain anything to us either. Sorry if he's actually possessed." Zuko groaned, Katara chuckled and Aang was in the corner apologising frantically. Yue had actually left the oasis long ago, unable to handle the awkwardness.

The Dragon of the West sighed, "This is all very strange. I have not heard of this happening before. But do not fret, avatar, I am sure you did not mean for this to happen." Iroh went back to his calm self, secretly thinking of ways to exorcise spirits.

"Hi, I don't mean to barge in, but what do we do about the siege?" Katara said, breaking the silence. Everyone looked a little guilty as they had all forgotten about it after defeating Zhao. While they were chatting in the spirit oasis, hundreds of Northern Water Tribe soldiers were fighting for their lives… 'Oops,' everyone thought.

"Actually," Iroh said wisely, "I am quite sure the Fire Nation has retreated already. The soldiers who ran away would have chosen to do so, unless I am wrong. Admiral Zhao was the one leading the attack, after all." There was a sigh of relief from all. Iroh turned to his nephew, "Prince Zuko, what are you going to do now with your… uh… knowledge of the future?"

"Dab on the haters," Zuko said with determination in his voice. "Um, I mean join the avatar and end the hundred year war."

Zuko dabbed anyways.

Iroh remembered that salt could be use to banish spirits, and made a mental note to stock up on it later. "Stay safe, my nephew. I'm afraid I won't go with you, but I support your every decision." Iroh wondered if he could ask the waterbending girl to bend salt out of water later.

Standing completely still, the firebenders didn't move for a very, very long time.

"…"

"…"

"Fuck it," Zuko announced as he inched towards Iroh and hugged him. The two of them shared an embrace. Such a heartwarming moment, surely nothing could go wrong.

"Uncle," Zuko said suddenly, "I'm hungry."

That broke the moment. "…You should get something to eat, then." Iroh said confusedly.

"No!" cried Zuko, "You're supposed to say 'Hi hungry, I'm dad'." He broke down, "I'll never experience a dad joke!"
