It's time.

He fingered the black box in his pocket and sighed as he knocked on the Athena cabin. Silence. What if she's not in there?

"Annabeth?"

There was a flash of blonde curls in the door behind the bunk bed.

He heard that voice, the voice of the girl who saved hims dozens of times.

"Okay, Piper, go and call Percy."

"On it!" He recognized it as Piper's voice.

Piper ran out the door huffing and stopped immediately when she saw her.

"What going on?"

"Stuff. Come in there." She pointed to the door and ran back into it.

He was greeted by a pondering Annabeth, an unconscious Jason, a non-caring Nico, a suprised Thalia and a worried Piper.

And, a black portal in the middle of the...bathroom?

"Whoa." Percy gasped.

Annabeth nodded in agreement "It showed up just this morning."

What if it was a monster in there?

Jason was finally up, Piper hanging on to him, because he was still wobbly.

"What happened to Jason?" Percy asked.

Annabeth said "He peered into the portal and...fainted. Almost immediately actually."

Not a monster...

Jason, ran away from Piper and put his hand on Percy's shoulder for support.

He said "Girl...Me...in there!" He said panting.

Okay that just doesn't make sense...

Annabeth said "What? What did you see Jason?"

Jason stopped panting and said "I peered inside, and there was...Me."

Like a mirror.

Annabeth arched her brows. "You?"

"Yes, but at the same time, it wasn't."

What? YOU? But not you, ouch.

Percy scrunched his eyebrows. "Well, that's hurting my brain."

"What do you mean, You, but not you?" Annabeth asked, suprised.

"It was me alright, a GIRL me."

How...odd. Something or someone is in there.

Everyone in the room was silent. Percy said "We have to go in."

Annabeth sighed "But wait, how do you know it was you in girl version Jason?"

"There was a connection. That told me, this-I mean her...is you." Jason said.

I made a conclusion.

Percy nodded. "It's there for some reason."

Annabeth rubbed her chin and said, "How do we know it's safe and stable?"

Suddenly, there was a whir of black hair and someone screamed.

When Percy checked the room, there was no Nico and an innocently whistling Thalia.

did Thalia just...no...no...no...

Annabeth said "What just happened?"

Thalia said "Hey, you said 'how do we know it's stable' so I pushed Nico in."

nononononono...

Piper suddenly piped in (bad pun) "No we really have to go in."

"Yes, yes we do!" Percy said and went in.

The daughter of Athena face palmed herself. That Idiot.

Piper said "Now what?"

"Thalia, you pushed Nico in, so go see what they're doing."

Thalia nodded and murmured "Probably killing themselves."

"Piper, go and tell Chiron we're going on a mission. No details."

"Kay'!" Piper saluted and went out.

"Jason…"

"MMm?" Jason looked up.

"Just keep doing what you were doing."

Jason bobbed his head down again.

"I swear on the river styx I am going to kill him!" Annabeth swore. "Both of them!"

Meanwhile…

Percy had transported to the same bathroom…but…

"Percy?" Nico asked,

"Nico?"

Percy observed his surroundings…Jason was right, the alternate universe.

"Hello, uhm, my boyfriends plan, sorta, uhm, backfired and stuff….so…." Percy directed his head to the voice. And there was…

Him….err….her?

"Anyways, I'm Pearl." The girl let out her hand. She had black hair, green eyes and was wearing a Camp-half blood shirt too.

While Nico was talking to his other self. A girl with short black hair and hazel eyes.

"Who's your boyfriend?" Percy asked. Pearl smirked and said "That braniac." And herfinger pointed to a boy with blonde hair and grey eyes. "Anthony."

Percy gaped. "He looks just like…my girlfriend in boy form."

Pearl said "How akward."

"I know right."

"We don't know anything."

They stared at each other, then combusted into laughter.

Little did they know three more people had come into the portal.

"Percy-?"
