Chapter 1: Coupleshow 101 - Airs after Doomsday

Disclaimer: (whew! almost forgot) I do not own Percy Jackson and the Olympians it belongs to Rick Riodian nor do I own the Mortal Instruments, it belongs to Cassandra Clare, but the plot is original and rightfully belongs to me (mine! all mine! mwhahaha)

Percy's POV:

Me and Annabeth were sleeping in ally when I woke up to a screech.

"Percy!" Annabeth shouted. I woke up in a instant.

"What, what is it?" I shouted.

"Monsters!" she shouted, "Lots of them."

There were, indeed, so many monsters surrounding all of them. There was no way to defeat all of them. I slashed out with the riptide. One of them raked out their talons and scratched my arm. The pain burned, but I kept on going. I would not let them capture me and Annabeth. Annabeth fearlessly fought their right by my side stabbing an ugly Karpoi that exploded into grain. Gods, she was pretty when she was fighting. Don't get distracted, idiot, I chaisted myself, as another monster attacked. A lingering sense of doom fell over them, the endless sea of monsters just kept on coming and coming. It would be like loosing the war all over again. Gaea would get them and Annabeth, oh gods, Annabeth… no not now, I thought, just fight, fight, fight! I moved the riptide around in a deadly arc, stabbing one monster after another. But they just kept on coming. We were surrounded. No retreat. Another monster made a lunge for my throat. I quickly stabbed it and kept on fighting, jumping, dodging, stabbing, my only goal to kill as many monsters as possible, before they got captured. Then Annabeth screeched, a monster splattered fiery acid all over there. She fell backwards onto the pavement. I jumped in front of her and stabbed the monster attacking her to dust.

"ANNABETH!" I screamed "Annabeth! Annabeth! Are you all right? Annabeth!" I sobbed. Gods, if Annabeth wasn't ok… another monster attacked, which I quickly dodged and sliced off its arm. It staggered over and I promptly killed it, its remnants exploding it to monster dust. I quickly checked for Annabeth's pulse. It was soft but still there. Thank the gods. Another monster jumped out when I heard a voice call out.

"Alec!" yelled the man. He had bright blonde hair and amber eyes, and he was indeed, handsome. "Grab the kids, we'll fend off the demons!"

"Fine!" shouted the other boy, who I assumed was Alec.

"Where do you want to take Annabeth! Do you work for Gaea?" I shouted at the boy. I had no idea wether I should trust them.

"I can help her!" the guy, Alec, I suppose, shouted. I made a split second decision; Annabeth needed help.

"Fine!" I shouted, "I'm coming with you then! Who are you people! Demigods? I've never seen you at camp? Are you in the legion?"

"Legion? What no? We're Nephlhim!" the Alec guy shouted back. "Whatever! Let's go!" We ran to what I suppose was their getaway van. It was a hideous neon yellow. It looked like a dead banana. Alec set Annabeth in the back seat and hopped into the drivers seat.

"You take shotgun!" he shouted. I wanted to be in the back next to Annabeth but now was not the time to argue. I yanked the door open and hopped into the front seat. Alec speed off onto the road. He was silent for a while before he started interrogating me.

"Who's Gaea? Is she the creepy Earth tyrant that appears all over the mundie news?" said Alec.

"What's a mundie?" I asked curiously. How did he fight monsters and not know about Gaea?

"You," he said.

"Excuse me?" I asked.

"Unless you are shadowhunter of course. Then no offense. But a shadowhunter as young as you couldn't have been sent on any Clave mission. What where you doing out there anyway?" he asked.

"What's a shadowhunter?" I said. This was starting to get annoying; I really hated being out of the loop. The guy looked puzzled but didn't respond.

"Here's the institute," said Alec. Annabeth let out a quick gasp from the back.

"Annabeth," I said with newfound urgency.

"We'll take her to the infirmary," Alec said reassuringly, "Magnus can handle demon poison."

"Huh?" I responded, rather stupidly on my part. "Nevermind. Where's this infirmary?"

"Look there," Alec pointed, "you should be able to see it. All shadowhunters can." I still didn't know what was up with the whole shadowhunter thing but I looked where he was pointing. At first I saw a rubble-ish looking thing but I had a feeling it was more then that. I looked again and the the image seemed to waver and it revealed a castle? Institute… right. What kind of school was in a secret castle?

"Come on," Alec said. I didn't need to be told again. I grabbed Annabeth, held her, bridal style and jogged up the institute.

"Mayrse!" Alec shouted, "Get the first aid kit?" then gestured for me to follow him. I walked after him into a grand looking room full of hospital beds. I softly set Annabeth onto one of them.

"Annabeth," I murmured softly.

"Your girlfriend?" he asked.

"Yeah," was all I said. I was gazing lovingly at Annabeth's face. Annabeth, the girl I loved, who I went through hell and back with. She had to be ok now.

"Don't worry, we'll take good care of her," said Alec.

"Do you have a girlfriend?" I asked, curious. He looked sort of surprised, and a little freaked out. "Oh, sorry, it was wrong of me to ask-"

"No," he said, "I'm gay. I do have a boyfriend, he's Magnus." I nodded still looking at Annabeth.

"You don't seem very phased by that do you? Most people freak out when I say that," Alec said with a hint of surprise in his voice.

"I had a friend who was gay. His name was Nico. I have no idea where he is now. I haven't seem him since the war with Gaea" I said sadly.

"Gaea?" he asked, confused, "Nevermind. You should probably shower and rest. I'll ask in the morning. There's a bunch of guest rooms upstairs. Go in whichever one you want. I'll ask Mayrse to leave some clothes up."

I nodded gratefully and headed upstairs. I didn't know who these people were, but in times like these anyone who didn't work for Gaea and who was wiling to offer help would do. Especially with Annabeth in bad condition. I looked around the institute. It was beautiful, it reminded him of Olympus but it had more of a gray scheme. It was like Olympus and Hade's palace combined with more of a victorian gothic feel to it. Annabeth would love it when she woke up. I saw an entire hall full of doors. I opened one that revealed a sweet looking guest room.

"Nice," I murmured. Curiously, I opened the door next to it. Inside was a similar looking guest room. I walked in and just slumped in a chair for a while. Someone knocked on the door. I jumped up quickly, ready for battle. Then I remembered Alec sent some clothes up for me. Groggily, I answered the door. A stern looking women stood with a set of clothes.

"Hello. I'm Mayrse head of the institute. You must be the boy Alec was talking about."

"Yeah, hi, I'm Percy."

"Here," she said, handing him the clothes, "You can come down in the morning." I smiled, gladly taking the clothes and hopping in the shower. The water was so refreshing, and felt good trailing down my back. Water was just awesome that way. After taking a shower, I tumbled onto the bed, and passed out cold. Just a nice warm bed, finally, for once. Surprisingly, I was able to sleep dream-free.I woke up in the morning, feeling pretty refreshed. The clothes I were given hung loosely, a little big for me, but not that big. Then I remembered, Annabeth. I rushed down stairs to check on her. There she was hanging down at the bottom of the institute.

"Percy!" she shouted, love filing her eyes, "Seaweed brain!"

"Wise girl!" I shouted, embracing her in a hug. We fell onto the couch and I kissed her fiercely on the cheek. "Annabeth," I breathed her name.

"Percy," she murmured.

"Thank every god your ok," I said, going for another kiss. I was interrupted by a laughing voice.

"Gosh, you guys have more of a PDA problem then Jace and Clary," said a gorgeous looking black haired girl. She was skinny, and tall, and reminded Percy alot of the women who gave the clothes to him yesterday.

"Geez, Izzy, they're having a moment. Besides, you know no one can display more affection," he said, wiggling his eyebrows, at the red haired girl across the room, whom I'm guessing was Clary, "then me and Clary."

"By the angel, Jace" she sighed, "just come here," the red head girl said, and kissed a happy looking Jace on the cheek, who quickly returned it, falling into her embrace. Suddenly, a very glittery man, walked in.

"Mmm, so were all having the couple show, aren't we?" he said, and grabbed Alec by the front of his shirt, and kissed him as well. Alec looked surprised, but quickly started to return it. Guessing this was Magnus. For a guy who wore so much glitter he had a regal… air to him. Lke there was a hidden seriousness in him behind all the flashy wardrobe decsions. I could see how he hooked up with Alec, who seemed serious, but I sensed he could be fun too.

"What? No fair! Simon isn't awake yet," said the pretty black haired girl.

"Kids! Stop that!" shouted the older looking version of black haired girl who handed me the clothes yesterday, Mayrse, I think. Hopefully, I didn't get that wrong. "We are here for a very serious conversation."

Magnus POV:

I walked in the room, excited to see Alec again. I was shocked to see Mayrse's meeting was overthrown buy a barrage of kissing couples. Perfect.

"Mmmm, so were all having the couple show here, aren't we?" I noted. I walked straight up to Alec and grabbed him in a deep kiss. He looked surprised but clearly he was enjoying it as much as me. That made me ridiculously happy. Me, the High Warlock of Brocklyn, felt slightly cliche as my pulse speed up and I swear my heart skipped a beat. I wrapped my arms around Alec, pulling him in. I pressed my lips against his cheek, slightly parted, inhaling his scent. I was about to kiss him again, when Mayrse of course had to get back on business. Darn shadowhunters. I suppose it was a business meeting, I mentally grumbled.

"I have some questions to ask all, once your are done with, your ahh.. scene, if you'd excuse me," Mayrse said, mainly directed at the new demigod kid, with the black hair and sea green eyes who was currently smooching a pretty blonde on the couch. Guessing Mayrse didn't intend to have the couch used for that reason. I snickered. Mayrseshout me a glare. It didn't phase me. I gave Alec another smooch then lazily sat down on an open couch. Alec hesitantly sat down next to me. I cuddled him, happily. Mayrse began to begin her lecture. I had to say, my interest was soon pipqued.

"Who are you? I was given a report that you use odd weapons, so it's unlikely you are shadowhunters," said Mayrse. The green-eyed boy gave a glance towards the other girl, who I assumed was his girlfriend, considering they were just kissing earlier. The blonde girl gave a slight nod and started to speak.

"I'm Percy Jackson, I am a demigod, a son of Poseidon from the greek myths," he said.

"I'm Annabeth Chase, I'm a daughter of Athena," blonde girl said.

"You're kidding right?" Jace said, cocky as ever.

"Demigods," I mused. Me, being the all knowing High Warlock of Brooklyn I had some insight on this situation. It was not long ago, I met someone else who knew about demigods. Nico Di Angelo and Will Solace.
