Sorry for not updating the last couple of days, I've been working crazy hours and haven't had a chance. I'm back now though! ^_^

Percy and Louisa managed three days with their mothers before they were ordered back to Camp. "Chiron knows how to deal with crazy better than us combined. You two are taking the cake."

"There's cake?"

"Oh, go!"

"I get the feeling we're not wanted here, sis."

"Funny. I was gettin' that too, bro."

"It's not that you're not wanted, it's that you're driving us crazy. How many other sixteen year olds sit in a fort eating junk food and colouring in? And wearing big blankets as capes."

"We never got to do fort-building though." Percy stuck his bottom lip out.

"'N' it's not all colourin' in. We've been drawin' too."

"And you're jealous of our style."

"The day I'm jealous of blanket capes will be the day pigs fly."

"Ooh, don't." Percy shook his head. "I've been caught out on that one." Jessica did a double-take. "I'd be happy to tell you. But you've upset the royals of the Fun Fort."

"'N' the punishment for that is complete exclusion from the Fun Fort."

"And there needs to be a ten foot distance between you and the royals."

"I'm sure Camp Half-Blood is more than ten feet away."

And that was why and how they were atop Half Blood Hill, three weeks before they were supposed to be, and not very impressed with either mother. They looked out over the camp for a moment and then Louisa considered Thalia's tree. "What's Thalia like?" She asked. "I don't think I've met her."

"I can introduce you to someone that you don't already know?"

"You ain't still sulkin' 'bout the Nico thing, are ya? Dude, I've known him for ages, I ain't gonna pretend I don't ta make you feel better."

"Treason." Percy muttered. "I'll take your cape." Louisa took a large step to one side and pulled the blanket tighter around her. "Thalia's a Hunter of Artemis. They drop in sometimes, but we don't always get on with them. And boys are a no-no too. Hunters are sworn to maidenhood, like Artemis, and they're made immortal."

"I'm likin' the sound of that."

"You would." Percy shook his head. "Race you." Louisa grinned.

"Bye." And she was gone, down the hill like a flash, cape billowing behind her. Percy sprinted after her, but it had long been determined that she was faster. He was still trying to beat nymphs in tree form; Louisa could get them to chase her. So, of course she won, she was sitting on her bunk with her blanket over her head, her eyes alone visible and gleaming victoriously. Percy said a few unsavoury things and felt a sharp tug on his cape.

"What the hell are you doing?" Annabeth demanded.

"We're royals. Of the Fun Fort."

"So you need to wear 'capes'?" Annabeth did the air quotes.

"Naturally." Louisa's muffled reply came. Annabeth didn't even question it, shaking her head. Louisa dropped the blanket about her shoulders. "Hey, you're datin' that. 'N' that makes me your honourary sister-in-law."

"Excuse me?"

"It's Lou-Logic." Percy shrugged. "She's adopted your cabin as her honourary brothers- and sisters-in-law."

"Uh, OK then." Annabeth rubbed at her forehead. "Why are you back so soon?" The twins took it in turns to explain. Annabeth admitted she honestly could not blame Sally and Jessica, "if I had to put up with you two behaving like toddlers, I'd send you somewhere else too."

"Gee, I hope ya don't mother any children soon."

"What?" Annabeth blinked at her. Percy suddenly realised he needed the bathroom and promptly vanished. Louisa just smiled, grin broadening cheekily as Annabeth turned red. "I'm going to go now." The blonde mumbled, batting into the door frame before managing to actually leave. Louisa counted to thirty and called her brother back. Percy creaked the door open a fraction, just enough to stick his head out and check the room was clear.

"She's gone." Louisa promised.

"Why'd you say that?"

"Oh, come on, bro, it's obvious that's what ya want."

"I never said- that's not- that's years off."

"Years off, mmmm?" Percy glowered at her, redder than Annabeth had been. Louisa flashed a wicked grin and he disappeared back into the bathroom. "You'd better name one of 'em after me!"

"I'm disowning you!"

"You'll regret it!"

"Hey. Hey, Beth. Wake up." Louisa bopped Annabeth on the head. Annabeth muttered and rolled over. "Blonide, wake up. I need ya help." Louisa gave a sharper tap to the blonde's forehead and hissed at her. Annabeth groaned and sat up groggily.

"Whaaat?" She whined, eyes heavy with sleep. "It's dark out, I should be sle-"

"Percy's gone."

"What?"

"He's gone. I woke up ta pee 'n' his bunk's empty. I've looked everywhere 'n' I can't find the prat."

"Underwater?"

"Duh." Louisa stood back, taking Annabeth by the arm to help her up. Annabeth caught a whiff of something metallic, spying a dark stain on Louisa's arm.

"What happened?"

"Harpy." Louisa muttered. "Look, that don't matter. I'm gonna keep lookin' for him, I need ya to go 'n' talk to Chiron."

"Why me?"

"Can you swim at the bottom of the ocean?"

"Fair enough." Annabeth pulled on a jacket and her sneakers and they raced out. Louisa disappeared at Cabin Three, a splash following a few seconds later. Annabeth kept going, the shrieks of harpies filling her ears. "Chiron!" She called, clattering up the steps to the Big House. "Chiron!"

"Annabeth?"

"Chiron, you haven't seen Percy, have you?"

"Percy? Not since dinner, my dear. Why?" Annabeth relayed what Louisa had told her. "Has he left anything? Belongings, a note?" Annabeth hesitated. Chiron directed her back out, dispelling the harpies with a wave of his hand. They searched Cabin Three. Louisa had obviously torn the place apart beforehand, Tyson was sitting up in his bunk, sobbing quietly. "Tyson, my boy, it is alright. We will find your brother. I'm sure he hasn't gone far."

"No. I cannot smell him." Tyson's bottom lip wobbled. "My sister is looking for him, but he is gone. Far away."

"Did you see him leave?" Annabeth asked. Tyson shook his head and burst into a fresh wave of noisy tears. "Chiron?" Annabeth looked to their mentor, patting Tyson's arm. He wailed and Louisa crashed in, tripping over a pile of clothes she had chucked to the floor.

"Ow." She groaned.

"Did you find anything?" Chiron quizzed.

"I found my paintbrush." Louisa pulled it from under the bed. "But nothin' about Percy."

"The light took him!" Tyson wailed.

"Light?" Louisa pushed herself up. "What light?"

"There was light! It woke me up! I thought it was morning, but the stars are out! Then I saw Percy was gone!"

"Why didn't you wake me up?" Louisa demanded hotly. Tyson's bottom lip trembled and her temper faltered. "Ty, I'm sorry, but-"

"You woke up. I thought you saw the light too, but you went in bathroom. You did not see until you came back." Louisa moved forward and put an arm around her brother's shoulders.

"Light?" She asked of Annabeth and Chiron. Chiron's expression was grave. Annabeth was chewing her lip worriedly. "Is this some godly crap, has someone taken him?" Louisa demanded, voice raising. "Annabeth, watch Tyson. I'm gonna have a word with Dad." Louisa stomped out and dived back into the ocean. Annabeth looked to her young Cyclops friend. Thick tears stained his face, his eye fixed on her.

"Hey." She said softly. "It'll be alright, we'll find him."

"Promise?"

"I promise." Annabeth squeezed his shoulder. Tyson managed a watery smile and hugged her. "We'll find that idiot, Tyson, and give him a good slap for making us worry."
