A/N: Chapter two! Thank you to everyone that reviewed, I promise to try to reply to you individually when I'm able! I hope you enjoy the chapter! Please tell me what you think!

"What. Was that." Hazel breathed out incredulously as she panted up the mess hall stairs, Frank right behind her looking concerned. She looked woozy from blood loss and the sudden exertion of fighting off a horde of dragons.

"Dragons." Jason explained shortly.

"Noticed." Hazel grimaced. "I mean, what's going on? I woke up and Mr. Haddock said his son found us and then things started exploding."

They all brought her up to speed while Frank made her sit down and adjusted the bandage on her head that had become disheveled in the fight.

"So that's who we are." Hiccup concluded. "The only question is, who are you guys?"

"You..." Percy faltered. "…believe in gods, right?"

They nodded.

"Percy, no!" Annabeth said.

"They have dragons, Annabeth! And they believe in gods! There's no way they're completely mortal."

"Not completely…?" Hiccup began.

"We're the children of gods." Percy continued. "And I should prove it to you because right now you probably think I'm crazy."

There was a hushed silence. None of the Vikings knew how to take this.

Percy walked over to a barrel of water a few times bigger than a person, probably for dragons to drink out of.

He climbed in and submerged himself. Minutes passed.

"He's not coming up." Astrid said, panicked.

"Don't worry, he won't drown." Annabeth assured her. "Watch."

After much longer than humanly possible to hold your breath, he came up. Not even wet.

"What is going on?" Astrid whispered.

"Is that a miracle, like those Christians are always going on about?" Hiccup guessed.

"Nope!" Percy said cheerfully. "All me."

Annabeth rolled her eyes and smiled.

"Show off." She teased him.

She turned to the Vikings.

"He can breathe underwater because his dad's the sea god."

"Oh! I remember now!" Piper exclaimed. "Astrid! She was a Norse goddess who was more or less a counterpart to my mom."

"And who…who's your mom?" Ruffnut asked in astonishment.

Piper winced apologetically.

"Aphrodite. But I'm nothing like her, I promise!"

Jason grimaced.

"Well, as long as we're telling secrets…"

He casually stuck his hands in his pockets and strode forward, each step carrying him higher into the air.

Fishlegs fainted.

After his friends revived him, the Vikings stared open mouthed as they explained there were two camps full of demigods.

Hiccup shook his head.

"Okay, I sorta get it. So what are you guys doing here then?"

"We were on a kind of quest." Percy explained. "It...well, it's hard to explain but our parents, the gods, they've sort of gone schizo."

"Schizo." Astrid repeated flatly.

"Er, that is, they're divided between two versions of themselves. But they gave us this mission to defeat Gaea who is basically Mother Earth gone Dark Side."

"We were on our way to finish off two of her children that are helping her." Jason said. "Twin giants."

"Twin giants who have my brother." Hazel added.

Hiccup looked at her in surprise. His expression suddenly became serious and determined.

"Well that settles it. We're taking a look at your ship right now."

"Giants." Astrid mouthed as Hiccup dragged her down the stairs with him.

"Aw man, what about dinner, Hiccup?" Snotlout griped, following them.

"It can wait. C'mon, guys."

Leo sat in the middle of the scorched and ruined deck of the Argo, scowling with his face half buried in a blueprint. He used a fire burning in his hand to see the paper under the dark sky as the others inspected the lower decks. He occasionally spat curses in Spanish under his breath.

"I have no idea what language that is, but I can tell what you're saying isn't exactly pretty." A sardonic voice said.

Astrid was coming up the stairs, giving Leo a friendly smile.

He swallowed hard.

"Uh…hi."

Gods, why couldn't he stay cool around a beautiful girl?

"Hi. Mind if I join you?"

"Oh, ah…sure."

She sat down next to him and glanced at the blueprint. Leo blushed at how close she was leaning in.

Astrid whistled.

"Man, that's way too complicated for me. I'm definitely more of a 'show me who to fight and I'll kick their butts' kind of person."

"I wish I were like that! You have no idea what it's like being the scrawniest guy in the universe."

Astrid laughed.

"I have some idea."

Leo didn't know what she meant by that, but she was talking to him which was more than he could have hoped for.

"So where is everybody?" He asked.

"Down belowdecks still. I just thought I'd keep you company. You must be freezing out here."

Leo stared at the palm of his hand that held the flame that kept him warm. He turned to Astrid.

"…You're not a monster are you?"

"Why would I be a monster?"

"Well it's only…girls who are this nice to me usually turn out to be evil. Or have boyfriends. Who could flatten me."

She laughed again.

"Well, I have a boyfriend, but he's not going to hurt you, trust me."

"Who?"

"Hiccup."

"Oh."

Just his luck. A girl who was into scrawny, wimpy, brainy guys and she had to be taken. And from another dimension.

Right on cue, Hiccup climbed up the stairs to join them. To Leo's relief, he didn't seem bothered by him being alone with his girlfriend.

Hiccup just kissed Astrid lightly on the forehead and sat down to pour over the blueprints with Leo.

"Valdez, you are one mad genius." Hiccup proclaimed.

Leo grinned at the complement.

"Let's go to my workshop. I'll have all the parts you'll need there."

"Okay."

Leo was beginning to like this kid. He was, after all, just one of many guys who had his dream girl. Leo couldn't hold that against him.

"Hey, what was that?" Leo said suddenly.

He had spotted a light flickering in the open sea.

Hiccup ran to the edge of the deck and peered over. He squinted to see but his eyes quickly widened in surprise.

"OUTCASTS!" He bellowed.

The other Vikings charged onto the scene with the other demigods.

"Where? Where?" Tuffnut yelled, having put his helmet on wrong so it covered his eyes.

"Over there, idiot!" Ruffnut snapped and Snotlout spun him around to face the right way.

"They're getting away!" Astrid screamed.

Frank knocked an arrow and aimed it at the light. It whizzed across the ocean but the light continued to glow farther and farther away.

"Oh man! Almost!" He cursed.

"Who were they?" Jason asked in consternation.

"Bad news for us." Hiccup answered."They're Vikings that got banished from Berk. Their leader Alvin is obsessed with taking us over. If he had spies on the island who saw you, that is not good."

On Outcast Island, Alvin threw away the remains of his dinner of roast chicken and belched.

Out of nowhere, a small man with a scraggly grey beard and a tattered vest burst into his hut breathing hard.

"Morgan Svenson, come to report, Chief!"

"Eh, ve'y good, Morgan. What do ye have for me, then?"

"Visitors on Berk, sar!"

"Eh, so wha'? Visitors alla time on Berk, innit there?"

"Yes, bu' I was watchin' the whol' time, see, an' one o' um, a lad….he can…can..."

"Forra lova Thor, spit it ou'!"

"He can turn hisself inta a dragon, sar!"

Alvin stared in shock for a second before breaking out into an evil grin.

"Interestin'."
