Olympus POV

On the six-hundredth floor of the Empire State Building, otherwise known as Mount Olympus, the Olympians were arguing and yelling, it sounded like a mini-war. In fact, if the Mist didn't exist, the mortals probably would've heard it.

To begin with, Hera was screaming her head off at Zeus. Why? Because Hera found a picture of a beautiful blonde in his wallet, and needless to say, that infuriated her like Hades.

Speaking of Hades, he happened to be in Mount Olympus that day, much to the annoyance of Demeter. In fact, Demeter was telling Hades to take care of her daughter, and if anything bad happened to her, she herself will...well, you get the point. Hades was pretty much ignoring her, watching Zeus and Hera bemusedly. He loved it whenever Zeus and Hera were fighting, because Hera was the only one who can make Zeus cower in fear, and that's what Hades loved seeing.

"Unbelievable, Zeus!" Hera exclaimed, her face turning crimson red. "I wish that prophecy comes back! You cheated on me a lot less! If I get my hands on that mortal, you ignorant womanizer, I will—"

"My dear, please try to understand," Zeus pleaded, barely aware of the smirk he was receiving from Hades. "I've been married to you for nearly five thousand years!"

Poseidon and Athena were debating about Percy and Annabeth.

"You need to do something about your child, Poseidon," Athena insisted, eyeing her rival coldly. "I do not appreciate him spending time with my far more superior daughter."

Poseidon snorted. "Are you kidding me?" he retorted. "Athena, if anything, my son is far more superior than your daughter! My son happened to have saved Olympus, or did you fall in the Lethe and forgot about that?"

"Your son saved Olympus with the guidance of my daughter!" Athena yelled, finally losing control. "Do you really think your son could come up with a plan as elaborate as that?"

Poseidon turned red and splashed her face with seawater.

A few feet away from them, Artemis was giving Aphrodite a look of cold fury, which didn't seem to faze her much; she was just reapplying her eye shadow.

"Aphrodite," Artemis said through clenched teeth, "If I lose another one of my girls to one of your silly love games, I swear I will really break your face." She shook her head in despair. 

"I just sent my lieutenant Thalia to a public school, which unfortunately happens to be coed, so she can gather more girls for the Hunters. If she quits the Hunters..." she trailed off, so that it would sound more threatening. 

Aphrodite merely smirked.

"Artie, you need to relax," Aphrodite insisted. "Thalia's a big girl now, practically a woman, and—"

"She'll never be a woman, idiot," Artemis snapped. "She'll be a maiden forever. And don't you dare call me Artie!"

Meanwhile, Hephaestus was simply tinkering with some tools. He was surrounded by Apollo, Hermes, Ares, and Hestia.

"Jeez, this is boring," Apollo grumbled. "Everyone's fighting, and we're all just sitting here." He nudged Ares. "Why aren't you fighting along with them, anyway? Aren't you the god of war?"

Ares shook his head. "Not this kind of war," he said in a bored voice.

Hestia regarded them silently, but she was happy that at least some people happened to maintain peace.

"Hey, you wanna have a wrestling match?" Hephaestus suddenly suggested. Hestia sighed as the men eagerly nodded. Maybe not.

Zeus stood in the middle of the room. He stared at his wife's red yelling face, Aphrodite and Artemis arguing, Poseidon splashing Athena with seawater, Demeter screeching at Hades, who was still smirking at him and Hera, and his four sons wrestling like pathetic eight-year-olds being supervised by a babysitter ( Hestia ).

"Enough of this!" he thundered. Literally thundered. The bright weather changed outside.

Olympus was quiet. Hera was still fuming, but at least she was doing it silently. Zeus cleared his throat. "You are all behaving like children," he said, looking at Hephaestus, Ares, Hermes, and Apollo pointedly. Ares quickly let go of his headlock on Apollo and dropped Hephaestus's arm. Hermes slithered out of Apollo's grasp on his leg.

Suddenly, a small smile formed in Zeus's mouth. "Perhaps you'd want to know what it feels like to be children," he said softly, studying the Olympians one by one.

"Uh-oh," Athena said nervously. She knew the look on her father's face all too well. It means that he had a 'great' idea.

"Uh-oh is right, dear daughter," Zeus said. His electric blue eyes gleamed and he raised his arms, holding the master bolt.

Immediately, everybody screamed. They all felt a hot, searing pain in their immortal bodies. Even Zeus wasn't spared. He cowered behind his throne. Then everyone passed out.

After a few hours, Athena's eyes sprang open. "Di immortales," she grumbled, rubbing her painful head. Then she noticed everybody lying on the floor, totally unconscious.

They were all dressed in normal mortal clothes. But when Athena examined them closely, her eyes widened. "No...no..."

She frantically ran to a mirror. And screamed.

She was a teenager!

Athena touched her reflection, her hands trembling. She was wearing a light blue turtleneck and plain khaki pants. Her long blond hair was in a ponytail. Her face was very young-looking.

Suddenly, Poseidon groaned and stood up. "Athena, what's—" He saw himself in the mirror and screamed, too, although his voice was less high-pitched. He almost looked like his son, Percy. His dark hair was tousled, like he just rolled out of bed. He was wearing a ratty green shirt and baggy jeans. He looked like he was the same age as Athena, maybe sixteen or seventeen.

Slowly everybody woke up.

"Zeus, what have you done?" Hades roared. His dark hair was longish, and he was wearing a black hoodie with black jeans. That made his skin even paler.

Aphrodite and Artemis stood up in unison. Aphrodite looked like a teen supermodel. She was wearing a pink cashmere sweater and a black miniskirt, topped with some jewelry and light makeup. Her hair was one color, but then it seemed impossible to determine what color it was. Maybe it was blond, or auburn, or whatever, but her eyes still looked like a kaleidoscope. She squealed and hugged herself.

Artemis was wearing a silver tank top and paint-splattered jeans. Her long auburn hair was set in a regular French braid, but she looked a bit too old for her liking. Usually she'd look like a twelve-year-old, but now she looked sixteen, too.

Demeter was wearing a spring-green sundress, which went along with the white flats. Her hair was in pigtails.

Ares was wearing a red muscle shirt and khaki shorts. His hair was in a buzz cut, and he looked like a high school football player.

Hephaestus had on a black leather jacket and holey blue jeans. His hair was messy, and he still looked big and strong.

Hera was wearing a cornflower blue mini dress and heels. Her hair was pinned up. Behind her, Hermes stood there, wearing a plaid shirt and Converse sneakers. And finally, Hestia came, wearing a brown jacket and brown flats. Apollo still looked the same, and he had on a baggy "All-Time Low" shirt and jeans. And his hair was almost brown anyway, because it looked too greasy and stuff.

Silence. Hera put her hands on her hips and yelled, "Zeus! Get your fat butt here!" She really did sound like a teenager.

Zeus groaned from behind his throne. He was wearing a dark blue button-up and jeans. He opened his electric blue eyes and smiled at the army of angry high-school kids.

"Ha!" he gloated, feeling proud of himself. "Now, you're all teenagers! I hope this will teach you a lesson!"

"Guess again, genius," Hera snapped, pointing at the mirror.

Zeus checked his reflection. "Oh, nooo," he moaned. "I accidentally turned myself into a teenager!"
