So, some of you guys might be wondering how I updated this so fast. I think I sort of explained in the last chapter. Well, I initially had 6000 words for the first chapter, but I decided to split it since I felt like it was going way too fast.

Now, reviews.

Sheeta Anime: Thank you so much for reading and reviewing! Yes, this takes place during the summer, right before Annabeth leaves with her dad. You'll see that in this chapter. The summer of everything in the Prisoner of Azkaban (basically after this story is over) will be when the Sea of Monsters takes place. Again, thank you for reviewing and I hope you enjoy this chapter too :)

LET THE CHAPTER BEGIN

Disclaimer: Last I checked, I was a 13 year old girl writing a fanfiction in my room, not two authors who have made the best books ever

~Previously~

The young wizard clenched his fists in anger and growled out, "I had a little brother?! VOLDEMORT KILLED MY BABY BROTHER?!" As he shouted, the mailbox near him exploded as a result of his rage. At the name "Voldemort," Ron, Ginny, and Hermione flinched in unison while Dumbledore remained stoic.

"No, Harry. Your brother is still alive today."

At that moment, all the anger in him dissipated, only to be replaced with an overwhelming amount of hope. This hope seeped into his voice as he unclenched his fists and unconsciously leaned towards Dumbledore in anticipation. "Where is he?" he asked, a little out of breath from the sudden change of emotion

The headmaster smiled, the twinkling in his blue eyes intensifying at his student's happiness. "He lives in the States with your other aunt. She is your mother's sister. Her name is Sally Jackson, since she took your great uncle's last name when she went to live with him."

Harry practically began hopping from foot to foot, his face about to split in two because of his wide grin. "So, are we going to meet him? What's his name? Is he a wizard?"

"Yes, we're going to go meet him in a few minutes. His name is Perseus, and he is indeed a wizard. We're hoping he can come to Hogwarts, along with his friend who I have discovered is a witch," Dumbledore responded, amusement clearly into the old man's voice. "Now, I shall send your things to the Burrow and we'll be on our way."

He waved his wand and the luggage, along with Hedwig's cage disappeared, however Hedwig herself remained there. She flew up to Harry's forearm and pecked his shoulder affectionately. "Head to the Burrow, okay? I'll see you soon."

The snowy owl hooted in response and flew off as Harry smiled in her direction. The young wizard then turned towards his school's headmaster. Dumbledore held his arm out and said, "Grab onto my arm. We're using Side-Along apparition."

Harry gulped, suddenly nervous. What if his little brother didn't like him? What if his aunt and brother were like Petunia and Dudley. "Uh, Professor Dumbledore, how old is he exactly?"

"Well, my dear boy, he's a year younger than you, Ginny's age. Though, if he and his friend decide to come to Hogwarts, we'll be putting them in your year along with Ginny."

Harry turned to Ginny, smiling. "Ginny, that's great! We'll be having classes with you."

Ginny smiled back at him, albeit a bit nervously. "Right then, grab onto my arm," Dumbledore told the children. They did so, and once they arrived at their destination, every single one of them fell to their knees. Well, Dumbledore didn't, but the old man was used to apparating by now.

Harry gagged one last time before shakily standing up. "If that's what apparating feels like, I prefer using my broom."

The others nodded in agreement, still gagging. Hermione had her hand over her mouth in an attempt not to puke while Ron actually threw up a little in his mouth. Ginny just grimaced as she got up shakily. Dumbledore glanced down at Harry through his half-moon spectacles. "It does not feel as weird when you get used to it."

"So, this is New York?" Ginny asked, raising an eyebrow and looking around at the huge amount of people walking through the park. There were so many people, in fact, that no one noticed the five people that just appeared out of thin air, behind a few trees. Only some dogs noticed, but they barked at the trees as their owners pulled them along.

"Yes, I believe we're in Central Park," Hermione commented, smiling and looking around the beautiful park, though there was some garbage in the small lake and on the green grass. But hey, it's New York.

"Correct again, Ms. Granger," Dumbledore complimented, before coughing a little. "Now, follow me. We'll be walking to their apartment."

Dumbledore lead the way through the city, with Harry walking just behind Dumbledore. The others trailed behind them slowly, talking quietly. They passed by a lot of tall building and stores, and some playgrounds, when Dumbledore stopped them right in front of an apartment building.

"He lives in this building?" Harry asked, excitement seeping into his voice and established clearly onto his face. Ron chuckled quietly and nudged his friend's shoulder. Hermione just smiled at Harry, happy to see her friend so excited. Ginny smiled a little, thinking about what the two kids her age would be like.

The headmaster nodded, and rang the buzzer for apartment 4E. The buzzer was answered with a soft feminine voice that sounded hopeful. "Percy? Is that you?"

Harry, Ron, Hermione, and Ginny all froze at the voice, unsure of what to do, while Dumbledore cleared his throat. "No, Sally. It is I, Dumbledore. May we come in?"

The woman was silent for a minute before she shakily answered. "Of... of course."

The door unlocked and the group of five was let in. Hermione pressed the button, then they waited for the elevator. In a few seconds, the metal doors opened and the group piled into the small space. "Whoa, is this what muggles call an escalator?" Ron asked curiously, looking all around him, though it was a bit difficult, considering the fact that the elevator didn't have much space.

Hermione and Harry exchanged a look of amusement while the two Weasley siblings stared confusedly at them, waiting for an answer. "No, Ron. This is an elevator," Hermione corrected, suppressing a giggle. Harry had to suppress a chuckle as well. "An escalator is similar to an elevator, but the stairs move up or down instead of a small 'room.'"

"Oh," Ginny said thoughtfully.

The elevator beeped as the steel door opened into a narrow hallway. The group of five walked through the hallway until they found a door that read "4E" on it, labelled with iron. Dumbledore knocked on the door a few times until a woman with long, wavy, brown hair and blue-green eyes opened the door. She was biting her bottom lip nervously. "H-hello, Dumbledore. Oh, hello children. Please, come in."

The five entered into the small apartment as Sally closed the door behind them. She led them to the new living room and invited them to sit. "Please, sit down. Forgive me for the boring room. I just moved here last month after my ex-husband disappeared," she explained, wincing a little as she said "ex-husband."

Dumbledore nodded. "I suppose you know why I'm here, Sally?"

Sally sniffled, nodding stiffly. "Yes, I do. Are you going to take Percy away? He's—he's all I have," the young mother told him, a few tears coming to her eyes.

The old headmaster shook his head, frowning. "No, of course not, Sally. He is your son, after all, even if not biologically. You raised him. We just want to bring him to Hogwarts, along with his friend Annabeth Chase. She is a witch as well."

The brunette stood, sighing. "He's still at Camp Half-Blood. I'll go call him," Sally offered before walking into the kitchen to the house-phone.

Everyone glanced at Harry to see his reaction. They were all shocked to see that his eyes were widened and his mouth was hanging open. "Harry, you alright, mate?" Ron asked, obviously concerned for his best friend.

The Potter boy nodded, closing his mouth, though his eyes were still widened. "Y-yeah. It's just... Professor Dumbledore, you said she's my aunt on my mom's side, right?"

Dumbledore nodded in response. "Yes, she is. She was your mother's younger sister by two years."

"So, why couldn't I have gone with her along with my little brother?"

The grey-haired man hesitated before speaking. "We needed you in England. We could've protected you better."

"Then why didn't you leave him with me? Why did we have to be separated?"

Just then, Sally walked into the living room. She caught her first glimpse of Harry and staggered backwards. "Harry, is that you?"

Harry hesitated for a moment before nodding. Sally smiled sadly. "I wish I could've taken you instead of my older sister, Petunia. I could have raised you and Percy and you wouldn't have had to have been separated. How are they treating you there?"

Harry shook his head, frowning. "They all hate me. They locked me in a cupboard for 11 years!"

Sally let out a sigh of frustration. "Petunia always was jealous of Lily's ability to do magic. I told Dumbledore he should've given you to me!" she explained, glaring at Dumbledore.

Suddenly, a loud noise sounded in a room nearby with the door closed. "MOM!" a young boy cried out.

"Ms. Jackson?" a girl called out cautiously.

~Percy~

Percy was recovering from the scorpion's sting. He was standing on the porch of the Big House, hugging Annabeth goodbye.

"Make sure you IM me at least once a week, Seaweed Brain," Annabeth ordered, pulling away from him with a gentle look on her face.

Percy gave her a lopsided grin. "Of course I will, Wise Girl."

Just then, Chiron walked back out onto the porch, looking grim. "Percy, my boy. Your mother is on the phone."

Percy turned to Annabeth, his eyebrows furrowed with a silent question. Can you stay until I talk to her? With a sigh and a roll of the eyes with a small grin, she followed Percy inside to the house-phone. The son of Poseidon picked the phone up and spoke into it, not knowing it was on speaker. "Mom?"

"Percy, I need you to get home right now!"

"Wait, what happened?" he tried to ask before his mother hung up.

Annabeth stared at him with her eyebrows furrowed. "Percy, I think we should go to your new apartment. What if your mom is in danger?"

Percy nodded. "Yeah, of course. Wait, did you say 'we?'" he asked, his eyes widening.

The daughter of Athena smirked. "Yes, Seaweed Brain. You think I'm going to let you run into more trouble by yourself?"

He grinned at his second best friend and nodded. "Alright then. I think we should take a pegasus home. It'll be quicker than the van. Go let your dad know and I'll meet you at the hill."

Annabeth nodded and ran off towards the hill as Percy ran off towards the stables. He stopped sprinting once he was outside the stables, then he walked in, huffing. "Hey, who's the fastest pegasus here?"

'I am,' a single male voice responded. The son of Poseidon looked into the direction of the voice and saw a beautiful white pegasus standing there. It was the one he always saw Silena riding on, teaching the younger campers how to ride pegasi.

"Well then, would you mind taking me and my friend, Annabeth, to my apartment? I think my mom's in danger."

'Sure, why not?' the pegasus responded.

The pegasus kneeled onto the ground so that Percy could easily get on. Once the raven-haired boy climbed onto the pegasus' back, they flew off towards the hill. "Um, what's your name, by the way?"

'I'm Porkpie.'

Percy had to suppress a snort at that as they landed on the hill. Annabeth was hugging her father and was just about to pull away when Percy hopped off the pegasus. Annabeth grinned at Percy, who bit his lip nervously. "A-Annabeth, you ready to go?" he asked tentatively.

The daughter of Athena nodded. Porkpie kneeled down onto the ground so that the two demigods could get on easily. Before Percy got on though, he walked up to Annabeth's dad and held his hand out. "Um, hello, sir. I'm Percy Jackson, son of Poseidon, it's, uh, nice to meet you," Percy greeted, blushing when he stuttered.

Frederick smiled and shook his hand. "Nice to meet you too, Percy. Thank you for keeping my daughter safe on your quest."

Percy snorted before he could stop himself. "Me, keep Annabeth safe? No, Mr. Chase. She made sure I didn't die the entire time, but don't tell her I said that."

"I heard that, Seaweed Brain!" Annabeth exclaimed, smirking. "And he's right, I did make sure he didn't die. But he did the same with Grover and I."

The son of Poseidon blushed. "Shut up, Wise Girl. Anyway, we should get going now." Percy hopped onto Porkpie, Annabeth following suit. "I really hope my mom's okay," he admitted, biting his lip for the millionth time that day.

"I'm sure she'll be fine, Percy. But let's go check." As the white pegasus launched into the air with Percy giving him directions mentally.

"Hey, thanks for coming with me, Annabeth."

Annabeth smiled. "Of course, Percy. Like I said, I have to keep you out of trouble, don't I?"

Percy let out a chuckle. 'Hey Percy, we should be at your place in two minutes.'

"Whoa, that was quick!"

"What? Are we almost there?" Annabeth asked curiously.

"Yeah, Porkpie said that we'll be there in two minutes. You really are the fastest pegasus at camp."

A few minutes later (or more specifically, two minutes later), Porkpie landed on a fire escape. The two young demigods jumped off of the white pegasus and waved to him. "Bye Porkpie. I'll see you soon," Percy said, waving. Soon, the grin left his face and worry replaced his initial excitement of riding on a pegasus. "Annabeth, take your dagger out, I'll get my sword."

"Whoa, Percy," Annabeth interjected. "How do you even know that this is your mom's apartment?"

Percy rolled his eyes. "It says 4E on the corner of the window," he explained as he uncapped a pen and it grew into a three-foot bronze sword. Annabeth unsheathed her dagger and picked the lock on the window. The two kids slid through the window, inside the apartment.

"MOM!" Percy cried out, unable to calm himself down. He had, after all, lost his mother earlier that summer.

"Ms. Jackson?" Annabeth called out carefully.

When nobody responded, Annabeth silently cursed. Her friend's mother might be in trouble after all. "Percy, keep your sword out. We need to come up with a plan."

~Harry~

"Percy, keep your sword out. We need to come up with a plan," the girl said quietly. Wait, sword? Also, wasn't his brother's name Perseus and his Aunt Sally called him Percy for short? Still, what was Percy doing with a sword?

"But what if they already took her, Annabeth? I can't lose her again!" the boy argued, sounding distraught. Harry could swear that he heard him sniffle. Again? Harry thought, alarmed. He shared a look with his friends, and they looked just as baffled as he felt.

"Percy, I'm sure that if someone did take her, she's alive."

"That makes me feel a lot better, Annabeth."

"Now let's come up with a plan," she stated, ignoring the boy's statement.

Harry's breath quickened. His brother and his friend were already here. His little brother had a bit of a higher voice, but to be fair, he was 11, about to turn 12. Then Harry heard someone take a step forward as the girl (Annabeth, or something like that) was talking (probably Percy). A loud thud was heard in the room as Annabeth burst out laughing. "Seaweed Brain, you idiot!" she teased, giggling.

"Shut up, Wise Girl," he demanded, embarrassment plain in his voice. The wizard could imagine that he had a red face.

"Honestly, Percy, they probably already know we're here with your clumsiness," Annabeth joked, before lowering her voice. "Let's just burst out there. We might be able to surprise them and gain the advantage like that."

They heard quiet footsteps coming closer to them before the door was pulled open. Just before then, Harry snuck a glance at his aunt's face, and she looked... amused? Anyway, the two kids burst out of the room, pointing weapons at them. Harry studied the boy (his brother), and to his shock, saw that he looked almost exactly like him. There were only small differences, like how he had sea green eyes instead of emerald green and Percy's hair was a mix between curly and wavy, and it was a longer than Harry's. He was also a bit more tan.

His younger brother's friend, Annabeth, had long, curly, blonde hair that was tied up into a ponytail. She was also tan, and with a silent gasp, Harry realized that her eyes were dark grey, and they were very intimidating.

Also, why the heck did Percy have a bronze sword and Annabeth a bronze dagger?

What?

"Crap, Annabeth. They're mortals," he whispered loudly. He exchanged another look with his friends. Mortals?

Annabeth rolled her eyes and punched his arm. "You think I didn't notice that, idiot?"

The raven-haired boy pouted and rubbed his arm. "Ouch, Annabeth. That hurts!" he complained as he seemed to study their faces. Once seeing Aunt Sally's face, he dropped his glimmering, bronze sword and ran to her. "Mom! We thought you were in danger!"

Wait, mom? Does that mean that Percy doesn't know that Aunt Sally isn't his real mother? Sally kissed Percy's forehead before pulling away from the hug. "Sorry, Perce, but I needed you to come as quickly as possible."

Percy narrowed his sea-green eyes slightly at them as he backed towards his sword again. He picked it and put a pen cap on it. What was the supposed to do? His question, however, was answered straight away when he saw that it had shrunk into a ballpoint pen. Percy put the sword-pen away, into his pocket. "Annabeth, you should put your you-know-what away."

She nodded, sheathing her dagger again and hiding it underneath her orange CHB shirt. "Hey, I'm going to try to manipulate the Mist." Geez, Harry had so many questions right now. Why did they have weapons? What the heck is the Mist? Does Percy know who his real parents are? Annabeth then looked them all straight in the eye and snapped her fingers. "You saw no weapons and you don't remember anything except for us walking in empty-handed."

Ron nudged Harry, snorting. "She's mental. What is she talking about?"

Harry, Hermione, and Ginny shrugged in confusion. The blonde facepalmed. "Well, Percy, we're screwed. They're clear-sighted mortals."

"I'm no mortal," Dumbledore interrupted, his blue eyes twinkling. The two kids raised an eyebrow in unison. "Son of Hecate, at your service."

More questions! Son of Hecate? Harry vaguely remembered reading a Greek mythology book, and it said that Hecate was the god of magic, or something like that.

Percy's mouth dropped open as he gaped. His mouth began opening and closing like a fish. Annabeth smirked as she push his jaw up so that his mouth was closed. "Seaweed Brain, I think you're turning into the fish that you were always meant to be. I think your father would be proud of you."

Harry's eyes widened. Did they know who Harry and Percy's father was?

The son of Poseidon rolled his eyes. "And what are you meant to be, Wise Girl? An owl? Ooh, or better yet, a book?"

Harry could tell that they were pretty good friends if they had nicknames for each other. Annabeth narrowed her eyes and punched his arm. "Whatever, idiot."

The headmaster chuckled, interrupting their bickering. "Well, I am Albus Dumbledore. You may call me Dumbledore. We're here to talk about your family."

Sally bit her lip. "Let me tell him, Dumbledore. Percy, I... I'm not your mother."

Percy staggered backwards, his eyes becoming comically huge. "Wh-what?"

"I'm your aunt. After my older sister, Lily, died, you were given to me."

The green-eyed boy fell down to his butt, his eyes still widened. Annabeth kneeled next to Percy, her eyebrows furrowed in obvious worry. She sat down with him and put an arm over her shoulder. Dumbledore cleared his throat as he stood. "Please, let me explain Sally. Hecate, the goddess of magic,—"—Harry had said that Hecate was the god of magic. He'd bet anything that if he told her, Hermione would be offended—"—created a world of wizards and witches. Her children were some of the first magic users. Purebloods are those who have descended from her children. Muggleborns are those who have been blessed by Hecate. Half-bloods-"-here he winked at the two demigods on the floor-"-are the children of purebloods and muggleborns.

"Annabeth Chase, you are a witch. you are a half-blood-in more ways than one,—"—what was that supposed to mean?—"—as well. Your father is a squib, though he doesn't know it. A squib is a person born from a wizarding family, though they possess no magic. He was from a family of purebloods, but they wanted nothing to do with him when they found out that. Magic is known to skip generations from time to time. Percy, you are a half-blood as well. Your father, James Potter, was a pureblood, and your mother was a muggleborn. That is why Sally cannot perform magic. Your parents were killed by a dark wizard who was seeking to kill all muggleborns and muggles, because he believed that they were not worthy. His name was Voldemort. He murdered your parents because he was looking for a boy with raven-black hair and emerald green eyes."

Harry winced. "But I have sea-green eyes," Percy told him quietly. The older Potter boy shook his head.

"Ah, but I wasn't talking about you, Perseus."

"It's Percy," he corrected subconsciously, which probably meant that people called him Perseus at first a lot if he didn't introduce himself as Percy.

"Right. I was not talking about you, Percy. He was looking for the first-born child of James and Lily Potter."

Percy's head whipped up to face Dumbledore, his eyes looking excited and hopeful. "I have a full-blooded older brother? Is he alive and okay? Wait, can I meet him?"

Harry smiled at his younger brother as he stood. "You already have," he answered, before Dumbledore could say anything.

I'M SORRYYYY! I meant to post this on Saturday, but I kept forgetting about it and I had to edit it. Next time I update the story, it'll be on Saturday. Honestly, I'll most likely have two or three chapters, depending on my memory. If not, then you'll only get one chapter. In my defense though, I have final exams in two weeks and all my academic classes have to hurry so that we can review everything we learned in the year. I love school.
