Hey guys!

I'm sorry that this week's story is taking a long time, but it's super long and I'm actually really really proud of it.

So in order to write this one I collabed with a friend of mine. luvwrestlinfangurl. She is new to this and just started her stories so please please go read them she is such a good author and please show her some love!

Now, I was having a very hard time figuring out a topic for this week but then I realised I never truly gave enough detail about how Aria and Percy found each other except that little summary in the first chapter, so here it is!

I hope you enjoy please remember to favorite, follow and review this story and if you're new to my stories I (try to) post every week!

Disclaimer: I don't own Percy Jackson, but Aria is mine. Also in the second "Age 15" (haha I know confusing) the part where Percy is getting offered the imortality thing that's all from The Last Olympian. I just felt some of us forgot the specific details from that part so I'm reminding you!

Please enjoy! This is my all time favorite story I've ever written!

Age 4:

New York, Jackson/Ugliano Residence

(Percy's POV)

"Percy! Give it back!" Ariana Jackson yelled chasing her twin brother around their small New York apartment. "You ate your cookie already, that's mine!"

"But Ari I'm hungry!" Perseus Jackson shouted back whining. The two kids continued running around, Percy just that much ahead of his sister. Finally as they were running around the kitchen table, the little boy tripped over his own foot and face planted hard onto the floor, the blue chocolate chip cookie flying out of his hand. Breaking into pieces.

"P!" Aria screamed running to her brother's side. She slowly pulled him up into a sitting position. Percy slowly reached up and touched his now bleeding nose. He then proceeded to erupted into a crying fit. "No no Percy, it's ok!" Aria said shushing him. "I can fix it, but we need to be quiet mom's sleeping remember." Sally Jackson, a failed author, was taking a well deserved nap from working a double night shift to raise her two lovely children. Her husband, Gabe, was somewhere out most likely gambling and drinking again. Aria led her brother to the bathroom, sneaking past their mother's room. Once there, they both hopped onto the counter. Aria then, quietly turned on the water. "Ok watch this." She put her hand out and closed her eyes concentrating very hard on the water. Percy watched as a small strip of water rised from the sink and gently coated his nose. He wanted to scream but he remembered what Aria had said, they needed to keep quiet for their mom's sake. He swallowed his protests and relaxed into the water. Soon, the pain he was feeling started to fade. When Aria opened her eyes again, both kids were amazed to see that his nose was completely healed, like Percy had not done anything to it at all.

"H-how did you do that?" Percy whispered, rubbing his nose over and over again. Aria shrugged and turned the water off.

"I don't know, I woke up one day and I just did it." She said nonchalantly both hopping off the counter.

"Ari, we have to tell mom! She'll be amazed!" Percy shrieked.

"No!" Aria said immediately. "We can't."

"Why?"

"I don't know." Aria said rubbing her arm. "I just have this feeling in my stomach that we shouldn't." Percy noticed how scared his sister looked, as if she knew something he didn't. After a little hesitation, Percy smiled and put a hand on her shoulder.

"Ok Aria, if you don't want to we don't have to."

"Thanks P!" Aria then flicked her nose. Percy smiled and did the same thing. When Percy and Aria were younger they came up with a little gesture that they would do to signal their lifelong friendship.

"Now let's go sneak some more cookies!" Percy said with a trouble-making smirk.

Age 6:

Empire State Building, 600th Floor, Mount Olympus

"There are too many brother!" Zeus yelled.

"No! You can't!" Poseidon argued. Slamming his trident against the floor of the main hall.

"I have already made my decision! You can't stop it." Zeus took a seat at his thrown, quite tired of this argument that has been going on for the past 2 days.

"I would never threaten one of your children, why must you threaten mine?"

"I have told you already, there are too many demigods running around!" Zeus waved his hand around as if gesturing to millions of kids running around his feet. "Brother be reasonable, you are one of the only gods that have most to no children! The council agreed that a god and a goddess must sacrifice 1 of their demigods. Both you and Demeter have been chosen. She doesn't seem to have a problem with it plus you voted yes!"

"Yes Zeus! I voted yes, but that was before I knew you were going to try and take one of my kids."

"It's too late brother. It has been decided, tomorrow at midnight one of your children, Perseus or Arianna, will be executed. But as a gift you may choose who will die and how they die." Zeus paused. "So who will it be?" Poseidon couldn't meet his brother's eyes. He just stared at the floor and tried to make the most impossible decision in his entire life.

"Ariana." He mumbled after what seemed to be millions of years.

"Very well. And how will she die?" Zeus asked.

"I'll do it myself." Zeus nodded. Then in a flash he disappeared. Poseidon was left standing there alone. In a huff he stormed off and made a courageous decision. He was going to save his daughter.

Age 6:

New York, Jackson/Ugliano Residence

11:55 pm (5 minutes before the sacrifice)

(Sally's POV)

"Sally, please wake up!" Sally Jackson was shaken awake. Her blue eyes shot open.

"What? Where!" She shouted. When her eyes focused she was met with beautiful sea-green ones. Ones that she had once fallen in love with. Ones that were passed on from the love of her life, to the loves of her life… her children. "Poseidon?"

"Hello Sally." Poseidon said smiling his shiny white smile. Sally was beyond confused, gods were supposed to cut all ties with their mortal partner and children.

"What are you doing here?" She said rubbing the sleep out of her eyes. She glanced quickly to see if Gabe was there. He wasn't. (Thank the gods) Mostly out with his friends.

"I don't have much time Sally, but I need to take Ariana." He said getting up and walking towards the twin's room.

"What?! No!" Sally said chasing after him.

"Sally please, something has happened on Olympus and this is the only way to save her." Sally put her arm in front of him. She knew fairly well that this arm was not going to stop him, but she was not going to let him get any further to her kids.

"Poseidon, I am truly sorry about what's going on with your godly family but I have made it very clear to you before that I want you to leave my family out of your life."

"Sally, we both know you can't keep this world from them forever! The monsters!"

"I don't care! Not until their ready!"

"Ok, but I need to take Ariana. Her life is in danger and if I don't take her with me she will die."

"What are you talking abo–" At that moment a loud crash of thunder boomed above the building.

"Sally, that's not a normal storm. It's Zeus and he's furious that Ariana isn't dead yet."

"Wait-wait… are you supposed to kill my daughter!" Sally yelled.

"Our daughter!" Poseidon corrected. "And I'm supposed to, not going to."

"You are not helping your case! No way are you getting your hands on my daughter!"

"Sally listen to me, we're running out of time. I'm trying to protect Ariana, Zeus wants her dead but I'm not going to let that happen. I love her too and I need to take her so I can fake her death and keep her safe." Sally hesitated. Sure she fell in love with this god, but she couldn't just trust that he was going to protect her daughter. "Sally I swear on the River Styx, no harm is going to come to our daughter, I will protect her with my life! No matter the risk." She looked straight into his sea-green eyes. The same ones that had distracted her when they first met.

"Fine!" She sighed and opened the door to her children's room. "But you swear to me, nothing will happen to her or so help me I will find you and send you straight to Tartarus. And I'm not lying." He nodded and walked into the room. Poseidon noticed the two different beds in the room. One with a little boy in it and one with a little girl in it. Poseidon, reached down and wrapped his arms around the little girl. Once she was stable in his arms she started to stirr.

"Mommy?" She said, her little eyes opening.

"Hey hey sweetie." Sally said softly, pushing her long raven hair from her face. "Honey, I know this doesn't make any sense, but this is your father, he's going to take you for a little while but Mommy will see you soon." She proceeded to kiss her little daughter on her forehead.

"BOOM!" Another clap of thunder boomed above them. This waking the little boy in his bed.

"Mommy what's going on? Who's that man? Why does he have my sister!" Percy shouted getting out of bed and running behind his mother.

"Percy it's ok, sweetie it's ok."

"No he's taking her!"

"Percy stop!" The claps of thunder were getting louder and louder in turn scaring the kids even more.

"Sally I must go." Poseidon said turning around. She nodded picking up her son. "But before I go… I want you to know I'm truly sorry about this."

"Sorry about wha-" Sally Jackson never finished her sentence, right at that moment her ex-lover turned around and flashed a bright light into her and her son's eyes. Sally couldn't be sure if it was just a hallucination of the bright light in her eyes, but she could have sworn that she saw Percy and Aria do a quick flick of the nose before the light fully blinded her vision. When Sally woke up she and her son were in their appointed rooms. She walked into her son's room, the second bed, she swore was there just last night, was gone. And the idea of having a daughter, just seemed to be a long lost dream.

Age 10:

Atlantis,

"Hi Daddy." Aria Jackson said running to her father's throne. As the daughter of Poseidon ran up to hug her father her stepmother, Amphitrite grimaced at the sight of her husband's other daughter.

"Hello my little Angel Fish!" Poseidon smiled, picking his young demigod daughter up and raising her as high as he could.

"I'm going to go find Triton." Amphitrite said swimming off with disgust written all over her face.

"Ok my dear." Poseidon called after. He knew perfectly well that his lovely wife did not approve of Ariana coming to live in Atlantis and when he first brought her home. Amphitrite had tried to drown her multiple times, but Poseidon was able to convince his wife that this was the only way for him to save Ariana. Once the Queen of Atlantis was well out of earshot he spoke to his beautiful daughter. "Do you know what day it is, Angel Fish?" Sometimes he hated looking at Ariana. It hurt him because she looked so much like Sally Jackson, the true love of his life. The one person he wanted to see more than life, but could never see again. Aria shrugged.

"I don't know."

"Wow, that's kind of surprising." He said still holding his daughter. "Honey, it's your 10th birthday, August 18th." There was slight hesitation on her face, but then the realization hit her.

"Oh right!" She giggled. He finally put his daughter down on the coral floor. He noticed how she was the only one in Atlantis who had legs rather than a fin. Occasionally, when no one was around Poseidon changed into his gladiator form with legs just to make his daughter feel comfortable. This was one of those times.

"Come with me, sweetheart." Poseidon and his demigod child walked around the palace. Right now, Poseidon actually felt content with his life, ah, if only Sally and Perseus could be here too. Once they were in his and Ariana's favorite place in Atlantis, the coral gardens, he stopped walking. "Alright my dear, I got you a present."

"Daddy you didn't have to." Aria giggled.

"Oh hush! I'm your father, of course I had to." Poseidon bent down on one knee so he could face his daughter. "Now, do you remember when I told you that you were very special?"

"Yes, you said I was a demi- a demi- a…"

"A demigod." The god finished. "But you are a very special one. You have amazing powers."

"I know daddy, you've been training me to control and use my powers since I was 6." She giggled.

"Yes and you have mastered it faster than I could have ever imagined." Poseidon ruffled the girl's hair. "Quickly making something out of the water!" Aria did as she was told and put out her hand. Right at that moment water started swirling around her hand then frozen into a small sculpture of a horse. "Excellent!" Poseidon couldn't be more proud of his little girl. "But that's not the only thing you need to know to be a great demigod." He paused. "You also need to learn how to fight and protect yourself from monsters." Aria nodded showing she understood. "So I got you a present to help with that." The god of the sea took out a small ring that had a frosty white diamond in the middle.

"Woah! That's so pretty!" Ariana exclaimed grabbing the ring from her father and putting it on her middle finger. Immediately as the ring made contact with her finger it shrunk to fit. "That's awesome! I love it!" She then proceeded to run and wrap her little arms around her father's neck. When they pulled away, Poseidon explained the rest of the ring's powers.

"Hephaestus made it especially for you. It's magic, it will always reappear on your finger if you lose it, it will grow and shrink to your finger size, and my absolute favorite part… press the diamond in the middle." Aria did what she was instructed. Soon the once small ring turned into a long sword, the blade the color of ice and the hilt was a light blue. The inscription above the handle was written in greek that read, Ice.

"It's a sword?" Aria said amazed.

"Yes, Angel fish. It's celestial bronze, it only kills monsters not mortals."

"Cool, but why does it look like ice?" Aria asked a little uninterested.

"That's the best part! Basically it will scare most to all monsters you'll face. It makes them think that your sword would freeze them, in turn freezing their soul's and if their soul is frozen it would never make it to Tartarus, meaning they would never regenerate." Poseidon saw how his daughter's eyes shined with joy and excitement.

~Time Break~

Poseidon pulled the covers up to his daughter's chin. Her eyelids drooped as she yawned sleepily. "Thank you for the ring, daddy."

"You're so welcome my dear. We'll start your training tomorrow morning." She nodded, rubbing her sea-green eyes that were an exact replica of his own. He started to see that was only similarities that they shared, every other distinguishing feature on her face mirrored Sally Jackson's.

Her dark wavy hair that curled around her face, her high uplifted cheek bones, her light rosy cheeks, the slight curve of her nose, and the overall dazzling effect that made his heart melt.

"Daddy when can I see mommy and Percy again?" Aria asked, shaking Poseidon out of his thoughts.

"I'm sorry, what?" Poseidon started.

"When can I see mommy and Percy again?" Aria repeated, giving him an innocent and hopeful smile.

"Uh… I'm not sure if that's possible." He watched as his daughter's face fell as her hopes were dashed. He despised himself for denying his beloved daughter her one true birthday wish. "You know your Uncle Zeus, he's just not fair sometimes. He says I have too many children and he doesn't want you to see our family."

"Oh."

"But! I'm trying very hard to convince my brother and we're getting really close!" Poseidon lied. Zeus and the Council didn't even know that Aria was still alive.

"Ok daddy! As long as you're trying!" She knelt on the bed and threw her arms around him. "You're the best daddy ever! I love you." Poseidon felt as if a hot dagger of guilt was driving itself into his heart. Before the guilt could complete its meal of his immortal body, he quickly walked out of the room. Aria settled back into her bed. Despite that she wasn't able to see her mortal family, she was satisfied that her father was trying to get her a visit. However, his answer did strike her as a little funny…

As she lay in bed, she subconsiously flicked her nose, a habit she'd grown into ever since she entered the watery realm of her father.

Age 15

Atlantis

(Percy's POV)

Percy blinked into focus. His head was spinning and everything seemed fuzzy. Out of the corner of his eye he saw a shadowy figure. Percy opened his mouth to speak to ask where he was but the only thing that came out of his mouth was, "Beckendorf." The figure jumped from shock.

"You're awake." The figure said. Percy realised that the voice was female.

"What?" The figure came into view. Percy saw a beautiful girl his age, with luscious raven black curls pooling over her shoulders. A stray curl hung over her smooth, glossy brow and her sculpted cheekbones must have been a contributing factor to her drop dead gorgeousness.(Don't tell Annabeth) Her rosy button of a mouth was fixed in a dazzling smile, friendly and concerned. Most distinguishing of all were her eyes, her startlingly bright sea-green eyes. They were so familiar, gentle green played with a darker hue of emerald. It felt as if a hundred bolts of lightning were arcing through his body.

"I said, you're awake." She repeated.

"Uh ok… just got one question. WHO ARE YOU? WHERE AM I? WHERE'S BECKENDORF? WHAT HAPPENED? WHY–" Percy tried sitting up but immediately groaned in pain.

"Don't move," The mysterious girl gently steered him back to his lying position. "You're injuries are pretty bad, it took me almost all night to heal you."

"What? You healed me?" Percy asked astonished. "I must have a thing for pretty girls healing me back to health." Percy thought.

"Well someone had to." This girl smirked. "Now, I know you have a lot of questions so please say them again slowly.

"Ok… uh… where am I?"

"You're in Atlantis."

"Wait wait, Atlantis? You mean my dad's realm?" He noticed how the girl winced when he said my dad's realm as if she didn't want to hear it.

"Yes, your father's realm."

"Right, and who are you?" The girl hesitated.

"I'm uh… I'm Ariana, but most people call me Aria."

"Aria," Percy thought. Why did that name seem so familiar.

"Wait, Aria…" The name seemed to linger on his tongue, as if he said it millions of times before. "Was anyone else with me when you found me?" Deep down Percy knew the answer… he knew that Beckendorf was gone, he knew that there was no way he could have made it too.

"Well uh… the mermen found you but they never reported another demigod, just you." The feeling of disappointment filled his body. Beckendorf, one of his closest friends at camp was dead and Percy couldn't do anything.

"Right… Um when can I see my dad?"

"I guess if you're well enough you can see him right now. I think he's in the throne room." Percy nodded. With the help of this Aria girl, he slowly rised from the bed. He noticed the girl was wearing ripped white jeans, meaning she had legs rather than a fin like the rest of the population had. Weird, very very weird.

"My legs are fine, I'm up here." Aria snapped, shaking Percy from his thoughts. When he looked up to face her he was sure that he was as red as a tomato.

"Sorry." He replied sheepishly.

"Right. Come on." They walked together through the castle. Percy was honestly amazed, the architecture of this place was amazing, high-rised pillars, high ceilings, amazing flooring. Wow Annabeth has been rubbing off on him.

"This place is incredible." Percy awed. Aria nodded, unamazed.

"Yeah it is, but you kinda get used to it after a while."

"Seriously! You act like you've lived here your entire life!"

"I have." Aria said coldly. Percy got the sense that Aria didn't like him, if he didn't know any better he'd say that she was jealous of him. What's to be jealous of?

Aria's POV

Aria couldn't believe her brother was standing right in front of her. Percy Jackson, one of the people she'd been waiting to see for years. Unfortunately she knew very well that she couldn't tell him anything, because if she did, Zeus might realise that she was still alive and find a way to kill her, or Percy. When Poseidon found out Percy was a demigod too, Poseidon decided he need to tell Aria the reason why he took her away from her mortal family and why she couldn't see them anymore.

Of course Aria was furious with her father for keeping this from her, and raising her hopes only to kill them, but after a while she understood that although Zeus was crazy idiot, he was still a powerful crazy idiot, and his wishes needed to be obeyed. Percy and Aria continued to walk throughout the palace until they finally reached their father's throne room.

"Ah! Percy you're awake!" Poseidon rejoiced. He was smiling, but his eyes looked tired and he stooped. "I see you've met my head general, Aria."

The merman standing next to his father harrumphed and crossed his arms. "I still think you made the wrong choice, Father. I would have been a much better choice than my half-si-"

"Thank you Triton,"Poseidon interrupted, a frown line knitting his eyebrows together.

Aria gritted her teeth and clenched her fists. Ravaging fool, they'd been rivals ever since she bested him in combat when they were little.

"Well too bad Triton, I have shown I am the better fighter, even though I have been training even last time than you. But by all means, I am totally willing to face you again and beat you for the 689th time in a row."

"Enough!" Poseidon yelled, obviously irritated. "Aria has been the general for about 2 years now and has done a wonderful job, this is the last time I want to hear this!"

Triton grimaced, but nodded.

"Aria, Trition you are excused. I want to talk to my son alone."

"Okay, da-" Aria stopped herself just in time. "I mean, Poseidon, sir."

Just before she left the room, she turned around one last time to see her brother. Her eyes filled with tears. Who knew if this was the last time they would ever see each other?

"Go on, Aria." Poseidon said gently, but firmly. He knew that she wanted to spend as much time as she could with her brother, but he knew for sure that the longer she spent with him, the more crushed she would be when he had to go. As soon as Aria was out of eyesight she did a quick, sad flick of her nose.

Age: 15

Empire State Building, 600th Floor, (Mount Olympus)

(Percy's POV)

"Perseus Jackson– If you wish, you shall be made a god. Immortal. Undying. You shall serve as your father's lieutenant for all time."

Percy stared at him, stunned, "Um… a god?"

Zeus rolled his eyes. "A dim-witted god apparently. But yes." Percy hesitated. He started to think back to all of the people who had given their lives for this war– Charles Beckendorf, Michael Yew, Silena Beauregard. He thought back to Ethan Nakamura and finally Luke. He knew his answer.

"No." The council was silent. The gods frowned at each other like they had misheard.

"No?" Zeus said. "You are… turning down our generous gift."

"I'm honored and everything." Percy started. "Don't get me wrong. It's just… I've got a lot of life left to live. I'd hate to peak in my sophomore year." The gods glared at Percy. He took a deep breath and began again. "I do want a gift, though. Do you promise to grant my wish?"

Zeus thought about this. "If it's within our power."

"It is. It's not even difficult. But I need you to promise on the River Styx." Percy sighed. "From now on, I want you to properly recognize the children of the gods, all the children… of all the gods."

"Humph," Zeus said. "Being told what to do by mere child. But I suppose…"

"All in favor?" Hermes said. All the gods raised their hands.

"Um, thanks." Percy said awkwardly. He turned to walk out of the throne room but Zeus stopped him.

"Wait Perseus. We have one more gift for you." Zeus sighed in exasperation. He waved his hand at Poseidon.

"Oh uhm… I'm not exactly sure how to explain this Percy but–"

"–You have a sister." A new voice finished. Percy saw a girl walk out from behind his father's throne. It was the same girl he'd seen in Atlantis, Aria.

"Aria." Percy nodded, acknowledging Aria's presence.

"Yeah." Aria let out a deep breath. "Percy, I'm your sister."

Percy was beyond shocked. He had a sister he didn't know about for his entire life. And his father never told him. No words came out of his mouth. The only thing that came to him mind was anger, so instead of saying anything he stormed out of the room leaving everyone behind.

Percy looked at Manhattan. Just a few hours ago Percy had defeated Kronos and killed his friend Luke. Then he got offered immortality but turned it down for a different wish, and then he figured out he had a sister no one told him about. It was all just too crazy for him.

"Hey Seaweed Brain." A voice said from behind him. Percy turned around to see Annabeth walking up next to him.

"Hey Wise Girl." He smiled.

"So…pretty crazy back in there."

"Very." He sighed. Annabeth gave him a sympathetic smile. "This is crazy. We won, but it turns out I have a sister that no one wanted to tell me about."

"But maybe it was for the best Percy. I mean gods do things for crazy reasons but they always have good intentions." He nodded understandingly.

"But Annabeth, when I met her the first time in Atlantis–"

"–Wait you've seen her before?" Annabeth interrupted.

"Yes, she saved me after Beckendorf…" Percy trailed off, he knew Annabeth knew what he was talking about and was thankful that she didn't make him say the words. "But when I met her, I could tell there was either something she was hiding from me or she knew something about me I didn't and turns out she was doing both!" Annabeth put a hand on his arm, that in normal circumstances would have made his heart do an aerial, but because he was so mad it truly didn't do anything. "Why didn't she tell me?"

"Maybe she couldn't Perce." Percy noticed how close he and Annabeth were now. Their shoulders were brushing against each other and their noses were almost touching. "Honestly, I don't think you should focus on that, I think you need to see that she's here now, and you need to get to know her." Annabeth said calmly. Just by hearing her voice, all of Percy's anger seemed to fade away. He was truly amazed at how Annabeth could just calm him down like that.

"You're right." Percy said. "Thank you Wise Girl." Percy pulled Annabeth into a hug that surprised both him and Annabeth. But soon they both relaxed into it. When they pulled away their faces were so close Percy could feel Annabeth's hot breath against his face.

"Ehm." A voice said from behind them. The quickly jumped away from each other. Percy saw that it was Aria standing there, her arms in front of her. "I'm sorry I didn't mean to interrupt, but I was just hoping I could talk to Percy for a second." Annabeth nodded and gave a kind smile. Then she did something that surprised Percy more than everything that's happened today. She gave him a quick peck on the cheek. She then started walking away giving a quick pat on Aria's shoulder. "When did they get so friendly?" Percy thought in his head. Aria walked up and stood next to Percy, but he refused to make any eye contact with her. He knew deep down that everything that's happened wasn't her fault but he was still furious. "She's gorgoues by the way, nice pick." Aria said. It took Percy awhile to understand who Aria was talking about, but then realised she was talking about Annabeth. He smiled a little but then remembered he was supposed to be mad. After that neither spoke, they just stood together in an awkward silence until Percy's ADHD got the better of him.

"So are you my sister sister or my half sister?" He said coldly not even looking at her. Aria hesitated for a second but then spoke.

"I'm your sister sister." She said not looking at him either. "Sally Jackson is my mother too." Percy winced at the mention of his mother… or their mother.

"Why didn't you tell me when I met you?"

"When the mermen found you floating in the ocean, I was with Dad. Because I am the head general of the army in Atlantis, all soldiers are supposed to report to me if anything is going on in Atlantis. When they said that they found a demigod floating in the water, Dad automatically knew it was you. I was beyond excited because I have been asking to see you and mom for years now, but dad always rejected the idea. He wasn't even going to let me see you that day, but I convinced him but there was one rule... I couldn't tell you who I was and what our connection is. I swore on the River Styx."

"Wow." Was Percy's amazed answer. "You're really prepared to answer all these questions." Percy turned his head slightly so he could get a better look of his new sister. He started to see the resemblances he hadn't seen before. They shared the same raven black hair, same highlighted cheek bones and the dazzling sea-green eyes. There was a small smile playing on her lips as if she was reliving memories.

"Yeah, honestly I've been waiting for this day for a long long time." Percy almost felt guilty. This girl has been waiting to meet him for god's knows how long, and he's been here not even knowing she existed.

"Don't feel guilty, Percy." Aria laid her hand on his arm. "Dad wiped your memories- and mom's. And I'm sorry for being so snappy in Atlantis. It's just, I was so relieved, concerned, scared, and I didn't really know how to act."

"H-how did you know I was feeling guilty?"

"You're uh face kinda fell and you were staring at me for like 2 minutes in deep thought so I kind of assumed." They stood together for another while until Percy asked the question he's been waiting to ask ever since he found out about Aria.

"Why did Dad do this?" Aria looked like she was taken aback but controlled her emotions.

"Zeus." She paused and took a breath. "When we were about 6 the council declared that there were too many demigods running around. The gods decided that one god and one goddess with the least amount of children had to give up one of their demigods. Dad voted yes not knowing he was going to be chosen. When he found out he had to kill one of us so he chose me and he wanted to do it himself, this meaning he could take me to safety. So when we were sleeping he took me and wiped anyone who's ever seen me memory. So basically I didn't exist anymore. He kept me hidden in Atlantis where no one could find me. Including you." She finished, small tears filling her eyes. "Percy, I have dreamed of seeing you again ever since I was a little girl. Dad always told me about your accomplishments and what you've been doing since you found out you were a demigod, and I was jealous that you were out doing things and I was stuck in some underwater kingdom. I mean sure it's cool, but it gets boring."

Percy had no words, just a couple of minutes ago he was truly angry at this girl, but after hearing her story he felt incredibly guilty for it. "Well none of that matters anymore. You're my sister, and always will be. I'm very very happy to see you again." Percy's smile grew even bigger when Aria rushed forward and wrapped her arms around his neck.

"I was so afraid you were going to hate me!" Aria sighed in relief. Percy gave a croaked laugh.

"Hard to hate you sister." He joked. Aria and Percy walked together to the throne room, talking, laughing, joking as if they were never separated.

"So I guess this means we have a lot of catching up to do?" Percy said after laughing.

"Yeah I guess it does." After a little pause Aria spoke one last thing before they walked into the throne room again.

"Percy do you happen to remember the gesture we used to do as kids?

"No." Percy said. "But I'm willing to learn." Aria nodded.

"Ok basically all you do is flick your nose." She flicked her nose and he followed what she did.

"Which one of us came up with this?" He asked.

"You did." she said laughing. "When we were little you said handshakes were lame. So you came up with this to, and I quote, "show our lifelong friendship."" Percy smiled.

"I was a genius!" The two Jackson twins laughed and shared one last flick of their noses. "A new lifelong friendship." Percy thought before the walked into the throne room together.
