Hey Guys, so as promised I wrote another weekly story for you guys. Again I apologise for quitting The Girl in the Water, it's just I had a really hard time finishing it.

So, I really liked the idea of Percy having a sister. Basically I decided, to make up for quitting Girl In The Water, to make Jackson Twins, a series. So I'll give you a quick backstory of Aria.

When Percy and Aria were born, Zeus declared there can only be one child of Poseidon and threatened to kill one of twins. To save his daughter, Poseidon took Aria and hid her in Atlantis with him. Aria continued to know about her past life and prayed everyday that she could one day meet her long lost brother. Unfortunately, Percy's memory of his sister was wiped and he grew up never knowing her had her until he saved the world and defeated Kronos. As an extra present to him, the gods told him about his sister, gave him his memories of her again, and let them meet up. From then on Percy and Aria were known as the Jackson twins. Aria is like Percy, except a little more mature and wise. They both fight as equals, but because Aria lived with her father for so long she got better training with her powers. She has better control than her brother and teaches him new things every minute. Both are strong alone but together they are almost invulnerable.

Disclaimer: I do not own Percy Jackson or his world, but I do own Aria.

Percy's POV

"No!" I yelled my face stuffed into a pillow.

"Come on P you're being irrational!" My twin sister complained. I felt her slowly sit down next to me on the bed. "It's just one dinner! Mom and Paul really want us there!"

"But Ari!" I said rising from my pillow. "It's also a Christmas dinner party for Paul's coworkers."

"So..?" Aria said obviously not catching on.

I sighed at her cluelessness… Hmm is this how Annabeth feels?

"It means our teachers are going to be there, having dinner with us!" Aria rolled her sea-green eyes.

"You are literally such a baby." She said running a hand through her raven black hair.

"Am not! And your bossy!" I yelled crossing my arms in front of my chest and pouted at my sister. She chuckled.

"Alright baby bro first of all never call me bossy!" She threatened. "Secondly, think of it this way, if you go to this dinner and make a good impression on our teachers then you could get A's for the rest of the semester." I will admit, that was pretty smart.

"Alright fine!" I finally gave in after 6 hours of denying.

"Yay!" Aria cheered.

"But for the record, your only older by 16 minutes, so it basically means nothing." I smirked.

"I left your clothes on your bed go get ready!" She giggled getting up and walking into the cabin bathroom probably not to be seen for another two hours.

~line break~

"Come on Ari! You're the one who wants to go, hurry up!" I banged on the bathroom door for the the 50th time.

"Give me a minute! Hold your hellhounds!" She yelled back. I sighed. I looked at myself in the mirror. Paul said that he wanted us to dress nicely so right now I was dressed in a dark blue button down, with a black tie, and black jeans. I smiled to myself. Aria really knew how to dress me. This wasn't super fancy but it also wasn't too casual. I was comfortable, yet I looked good.

"Best thing about having a sister." I thought. She could dress me nice without wanting to kiss me later unlike that stupid Aphrodite Cabin. For the millionth time I have a girlfriend!

"Ok, how do I look." I looked over at my sister. My jaw literally hit the floor. She was wearing a navy blue off the shoulder crop top, (urg I gotta stop listening to Piper and her Project Runway) with a black skirt. She had black pantyhose (ha pantyhose) on underneath, and she was wearing some ankle high boots that made her 2 inches taller.

"Uhh… No way!" I said suddenly feeling overprotective of my sister.

"Perfect! I'm wearing it." She said turning around and putting on her black leather jacket.

"Aria, you look like a stripper." I complained taking off my leather jacket and put it on her.

"Percy I'm fine!" She said taking off my jacket and handing it back to me. "If we don't leave now we're gonna be late so let's just go ok?" I sighed.

"Fine let's go."

~line break~

"Percy, Aria!" My mom yelled as opened the door. "You guys actually came!" She wrapped her arms around both of our necks.

"Mom, it's been kinda long!" Aria said, after about 5 minutes of our mother hugging the life out of us.

"Yeah, this hug as gotten so long, it's beyond awkward." I added on.

"Ok, fine!" My mother said letting us go. "I forgot you're both 17, you don't need your mom anymore!"

"Oh mom! We both know that's not true!" Aria said, walking over to her putting her arms around her shoulders. "We both still need you, I mean look at Percy, he can barely unzip his jacket!"

"Hey!" I yelled.

"Oh tell me that's not true!" She yelled back.

"I-I... you spend too much time with Annabeth!"

"Wow great comeback!"

"Urg! Fish Face!"

"Kelp Head!"

"Woah woah enough!" My mom said stepping in between us. "Paul will be back any minute with his colleagues and their families so please behave for 2 hours!"
"Right sorry mom." I apologized.

"Yeah sorry mom." Aria copied.

"DING DONG!" We heard the doorbell ring.
"They're here! Both of you best behavior!" We both shrugged at her. Aria and I both took off our jackets.

"You still look like a stripper." I whispered in her ear. This earning me a nice, settle elbow in the stomach.

"This, Karen, are my two kids, Aria and Percy." My mom said gesturing to me and my sister.

"Sally, their my students of course I know them!" Karen or Ms. Stewart to us, said. She stuck her hand out. "Nice to see you guys again." We both shook her hand and she gave us a fake sweet smile. Ok, to be honest almost none of our teacher's like us. Me more specifically. Aria is ok, she does good but most teachers don't like me. "This is my daughter, Ashley." She gestured to the blonde haired girl behind her.

"Uh Mom, I know who they are." She said rolling her eyes.
"Right of course sweetie." Ms. Stewart said, obviously trying to hide her frustration in her daughter.

"Looks like someone beat you in the stripper outfit." I whispered, nudging Aria. She rolled her eyes, but I could tell she agreed with me. Ashley was the stereotypical "popular girl," in Goode. She was a bully to everyone (including my sister) and flirts with me every second she gets.

"Oh guys you remember, Neil, or I guess for you guys Mr. Scott." Paul said. Ok, now this was getting good! Mr. Scott was by far my favorite teacher, mainly because he was the new Greek teacher in our school ( he gets most things wrong so Aria and I had to correct him all the time) because he was a young guy who was very down to earth with his students.
"Hi guys." He said sticking his hand out to Aria and I. "This is my wife, Linda and my son Jake." Jake had blonde hair and blue eyes, he had a football player's build, and had a somewhat douchey look in his eyes. I automatically knew I didn't like this guy.

"Kinda looks like a less hot version of Jason, don't ya think." Aria whispered to me. I couldn't help but laugh at her comment.

~line break~

All the "kids," had to sit at their own table and the adults sat at another. Right now, we were eating some turkey, mashed potatoes, stuffing, and other things that I couldn't name. I didn't complain about my mom's cooking because it was delicious but since this was an "official dinner" she couldn't put blue food coloring in it like she normally would. Right now, I was sitting next to Aria, across from her was Jake. I couldn't help but notice how his eyes were never truely fouced on her face, a little lower. I growled. I know she can take care of herself, but I'm still her brother plus I just hated guys like him. Nobody had said anything until Ashely finally opened her mouth.

"So… Aria, where did you get that shirt?"

"Uh, I'm not sure. I think it was a gift from my best friend." She answered.

"It looks hot on you." Jerk face said, prominently checking my sister out. I clenched my fists under the table. I was about to get up and punch this guy when I felt somebody's hand on my wrists. I looked over to see Aria holding my wrist, giving me a reassuring nod. I sighed and opened my palms.

"I know it looks hot on me, why else would I wear it?" She smirked. I smiled at her comeback. We all ate in silence for another long time when Aria started to have a conversation with me. "What'd you get Annie for Christmas?"

"Oh it's really cool." She nodded. "It's a necklace," I bent down and whispered the second part in her ear. "It's a heart necklace that glows when you're truly in love with the person who put it on you!"

"Aww Percy's that's so cute!" She squealed. I couldn't help but notice how her Aphrodite side was showing.

"Who's Annie?" Ashley said. We both looked up at her. Her hands were crossed in front of her chest and she was pouting.

"HA!" Aria laughed, then immediately covered her mouth with both her hands. She slowly removed her hands from her mouth and gave a smile. "Sorry, for a second I thought she asked who Annie was."

"I did." Aria's facial expression grew.

"Percy!" My sister pushed my arm. "I thought you talk about her every second you get! Gods she gonna be so heart broken when she finds out you don't talk about her every waking moment!" I rolled my eyes.

"I do." I muttered. She laughed again.

"Annie/Annabeth is my best friend or Percy's girlfriend." Aria answered. If it was possible for Ashley's face to fall even more than it already did because now she looked like she was on the verge of tears.

"I thought you were kidding when you told me that. I thought you were playing hard to get!"Ashley yelled.

"No, I really have a girlfriend. We've been together for almost 3 years now." I answered. I sighed. This dinner was turning out to be the longest, most awkward, dinner I've ever been to. Ashley looked miserable, I know I shouldn't have felt bad because...well… she was a b**** but I've never broke anyone's heart before and I wasn't ready to start right now.

"So… Aria, I'm guessing you have a boyfriend, but a sexy girl like you derseves someone better, like me." I was furious.
"Oh hades no! No one speaks to my sister that way you little piece of-" I said.

"Percy!" Aria said putting a hand on my forearm. "Stop." She was stern, determined. The adults were staring at us. I looked over to my mom, her face read a mix between curiosity and anger.

"What's going on?" Paul said, standing up too. I looked at Aria, she shook her head.

"Jake was hitting on Aria and he's been checking her out all night." I admitted. My sister sighed.

"I was not!" Jake defended.

"Oh don't you lie! I know you were looking at her lower area this entire night!" I yelled. All the adults gasped.

"Percus." My mom yelled at me. "These are guests. That's no way to act on Christmas." I was shocked. My mom actually took someone else's side rather than mine.

"Mom…" I said, my voice soft.

"Percy maybe you should go out for a while." Paul offered. Staring back and forth between me and his colleagues staring angrily at me.

"Your kicking me out of my own house?" I was astonished. My own family, kicking me out? No one said a word. Paul and my mom just looked down. "Fine." I huffed, walking over to the door, taking my jacket and walking outside into the cold dark night.

Aria's POV

I watched my brother open the door. I looked at my mom, her eyes filled with sorrow.

"Percy!" She yelled before the door closed.

"It's ok Mom, I'll get him." I said before grabbing my own jacket and following to where my brother might have gone. I walked down the stairs and out the lobby door. There was my brother sitting on the stairs that led into my mom's apartment. "Hey," I said taking a seat next to him.

"It's cold Ari, go inside." He said not looking at me. Keeping his eyes on the floor in front of him. "I could say the same thing to you P." I zipped up my jacket and crossed my arms hopefully to make myself warmer.

"I don't want to talk right now." He said, still not looking at me.

"You know what happened in there wasn't you fault right?"

"Yeah, but did you see the way Mom and Paul looked at me?" He finally turned his head to look at me. His eyes, tears filling them.

"Wow, The Great Percy Jackson! Hero of Olympus, destroyer of Kronos, Gaia, multiple titans/giants, and basically every single greek monster alive, main demigod in two big prophecy's, and child of the big three, crying?!" I exaggerated. He laughed at me. I smiled, I loved a lot of things in this world, the beach, my friends/family, and most of all making my brother happy.

"When you say it like that you make it sound like I'm amazing." He said, wiping a tear away from his eye.

"Cause you are."

"Thanks Ari." He gave me a small smile.

"Mom, isn't mad at you. She just wanted to make a good impression on Paul's friends."

"I know, but that Jake guy is very infuriating!"

"Woah, big word. Annabeth's rubbing off on you." I nudged him with my shoulder.

"Shut up. I never said that!" I rolled my eyes. "It's just the way he was looking at you… and all that, it's annoying. I hate guys like him." I smiled at my brother, I placed my small hand on his knee.
"Percy, it's really sweet that you care so much about me, but I can take care of myself." He nodded.
"I know you can, your strong and can fight just as well or maybe even better as I can, but still. You're my sister, and I don't want people doing that stuff to you."

"Percy, you can't control the way other people act. It's just who they are. But you can control how you act. And that starts by trusting me, and letting little things like that go." He sighed.
"And... it's forgotten." I smiled.

"Good! Now, let's go get some ice cream." I said getting up, and reached my hands out for him to take.

"Won't mom get mad that we're not back?" He said, staring back up at me.

"Well, considering you ran out and I chased you, I feel like she knows I'd take you somewhere to make you feel better." He let out a soft laugh before taking my hand and we ran into the darkness of the night.
