Zuko slammed his laptop shut in alarm as soon as he heard the bedroom door open. "Oh, hey Dad," he said as innocently as he possibly could.
"What were you doing before I came in here?" Ozai asked suspiciously, scanning the room. His gaze fell upon Zuko's laptop and the boy's hands pressing down on it hard, as if he was fighting to keep in from springing back open.
"Just watching porn," Zuko replied nervously. He knew that Ozai didn't care if Zuko wanted to explore his sexuality. It was a natural part of growing up, after all. His father had walked in on him watching three women spanking each other with chainsaws, reading erotic fanfiction about himself (getting with some girl named Katara who he'd never met…), and plenty of other unsavory things, but it didn't bother either of them.
But Ozai saw right through the ruse. "Show me your computer," he demanded.
With agonizing slowness, Zuko opened his laptop up to reveal…
"WHY ARE YOU WATCHING ANIME!?" Ozai screeched, instantly losing his temper.
"I just wanted to see what it was like," he sobbed, cowering.
"DON'T LIE TO ME, BOY! HOW LONG HAS THIS BEEN GOING ON?"
"It's Azula's fault! She dared me! And then I couldn't stop! It's an addiction. Please, forgive me, Father!" Zuko cried. "I can get help!"
Ozai yeeted Zuko's sinful laptop out the window, and glass shattered. "AND WHAT ARE THESE?" he shouted upon spotting some swords poking out from under Zuko's bed. "ARE THESE KATANAS?"
"They're dual broadswords!" Zuko wept uselessly.
"I WON'T HAVE ANY WEEBS IN THIS HOUSE!" Ozai screamed. The katanas/dual broadswords shortly followed the computer out the broken window.
"But Dad, the Fire Nation is based on Japan!" Zuko protested feebly.
"I WON'T HEAR SUCH SLANDER! YOU'RE BANISHED! OH, GOD! IS THAT A BODY PILLOW UNDER YOUR BLANKET!?"
"Yes, it is! I'm so sorry! Please don't banish me! I'll get rid of everything! It'll be like it never happened!"
Ozai's demeanor suddenly turned deadly calm. "No, Zuko. It will be like YOU never happened. Get out now, and don't come back until you've atoned for the disgrace you have brought upon this family."
He slammed the door shut, leaving Zuko alone to hug his Hatsune Miku body pillow and cry.
