Oh my gosh I am sooo sorry. I said I'd have it up by Sunday, but I didn't. This chapter went through so many revisions, and I liked this version the best. It's not perfect and I'm sorry about that. I was trying to make it a filler chapter that had more information and set up future chapters. I have half the next chapter halfway done so that should be up in the next day or two.

This is so embarrassing. I had someone point out to me that I used a line ("I'm the son of Poseidon. I can't drown and neither can my pancakes.") thay was actually from the HoO series, which hasn't happened yet in this story. Let's just say that it is a running joke between Percy and Annabeth that they use throughout their life time. I will go back and acknowledge this in the actual chapter it shows up in.

Thanks to those who reviewed. It was much appreciated and made me happy!

Chapter 5: My Undercover Mission Starts

Harry POV

I didn't know what to think of the American exchange student. He was taller than me, but not as tall as Fred and George. He had light beach tanned skin and messy black hair like mine, but his sort of messy was nice. Almost like the wind had blown through it just right. He had green eyes like mine, but instead of emerald, his were like the ocean. He looked vaguely familiar, but I don't know from where.

All I knew is that when Percy shook my hand, I resisted the urge to rub my scar. It burned and hurt when he touched me. The last time that happened, it was after I woke up from a dream about Voldemort. In the dream he said he was planning something, something that had to do with me. He killed a muggle who happened to be standing there while he was telling Wormtail to wait until after the World Cup. It was then I woke up with a burning scar and more unanswered questions.

I didn't know what to do. The pains were becoming more frequent, and I didn't know if I should tell anyone. I couldn't be sure it wasn't my imagination either. I mean, my scar only hurt, it seemed, when Voldemort was involved. But that couldn't be right could it? Percy seemed like a nice guy. He was genuinely sorry for breaking the tables; you could see it in his deep, seagreen eyes.

After introductions were in order, Mrs. Weasley insisted that Percy sit down and wait while the rest of us finished setting the tables. She said that he was a guest so he should be treated so. He replied, "I am your guest Mrs. Weasley, but that doesn't mean that I am above all of you. I would like to help you guys too. It's the least I can do for letting me stay with you." Before Mrs. Weasley could say anything, he made his way into the house and grabbed a rather large pot of boiled potatoes and carried them outside.

Soon, the tables were complaining about the weight of the food. All 12 of us sat down around the two tables. Mr. Weasley sat at the head of the table with Mrs. Weasley on his right and Percy, not the Weasley, sat on his left. I sat next to Mrs. Weasley and Ron sat next to me. Next to Ron was Ginny and then George. Hermione sat between both Percys and then Fred sat next to Percy Weasley and Charlie sat next to Percy. Bill sat at the other end of the table.

Arthur, curious as ever, started to ask Percy many questions about America. Percy just laughed and answered all of them. Molly asked if the food was alright to which Percy grinned and said, "Yes!" and then proceeded to stuff his mouth full of chicken and ham pie.

Throughout the dinner, we learned about Percy's complicated home life. His dad left when he was a baby but came back when he was twelve. When questioned more on his dad's side, he seemed to clam up and answered very vaguely. When Ron and I asked about Quidditch, he just looked confused like he had never heard of it before. Hermione asked about Ilvormorney, he answered but vaguely as well. He said things like, "It's a secret" or just winked.

Eventually he turned the topic over to us and asked about Hogwarts. It was then I realized he hadn't said anything about me being Harry Potter, the boy who lived, and it was kind of nice actually. Percy did seem to get sad when Hermione started to talk about the architecture of Hogwarts. Mrs. Weasley asked what was wrong and he just said he was missing someone back home. Mrs. Weasley brought out her home-made strawberry ice cream to cheer him up.

All in all though, Percy seemed like a good guy. Other than being a little bit weird, he was snarky and sarcastic, but also very kind and helpful. I couldn't find a reason as to why I felt that pain in the first place, and I don't know that wanting to be secretive about his school was cause for concern. All the wizarding schools are secretive, especially to each other. At least, that's what Hermione said.

After dinner everyone, even Percy helped clean up dinner. It was moments like this that I was reminded how bad my home life really was. Everyone pitched in with the chores and it wasn't just me. Over the years it has gotten better, but I still miss the fact that I don't have a family like the Weasleys. I'm just glad they have accepted me like one of their own.

Another odd thing about Percy was that he did his dishes by hand. "Why aren't you doing them with magic? Where's your wand?" Ron asked. "Oh um, I broke it. It's kind of embarrassing actually." answered Percy sheepishly.

"Right then, Arthur was unable to get everyone's school supplies so tomorrow we will all go to Diagon Alley. Now off to bed all of you. We have a busy day tomorrow.

Ron and I showed Percy up to Ron's room where he will be staying. Percy asked where the bathroom was and then headed in that direction. "Ron, we need to get Hermione. I've got to tell you something."

Ron, Hermione, and I made our way into Arthur's study which was unoccupied at the moment. "What is it Harry?" asked Hermione, her voice laced with concern.

"It's about my scar. It's been hurting." I said.

"Your scar hurt? Harry, that's really serious... You should talk to Professor Dumbledore! I'll go and check Common Magical Ailments and Afflictions, maybe there is something in there about curse scars." Hermione said.

"Your scar hurt? But... You-Know-Who can't be near you now, can he? I mean... you'd know wouldn't you? He'd be trying to do you in again, wouldn't he? I dunno, Harry, maybe curse scars always twinge a bit... I'll ask Dad." Ron said.

"No, I don't want anyone else to know. It could all just mean nothing and I don't want anything to be blown out of proportion. If it does mean something, I don't want anyone to be involved." I hastily said.

"When did your scar hurt Harry?" Hermione asked.

I told them about my dream.

"That sounds horrible. Bloody scary is what that is." Ron said.

"Harry, if you're having dreams as well you need to tell Dumbledore. The pain and the dreams have to be related and it's nothing good." Hermione exclaimed.

"Wait guys, there was another moment my scar hurt." They looked at me intently. "When Percy Jackson shook my hand."

*****Like break*****

Percy POV

Whenen I got to the bathroom, I used water out of the facet to create a rainbow. After a little practice, I was able to get liquid water to become misty. The light in the bathroom was enough to create a rainbow with the mist.

"Oh Iris, goddess of the rainbow, please accept my offering." I took a drachma out of my pocket and threw it in and it disappeared. "Show me Annabeth Chase Olympus. "

The rainbow showed me a mop of blonde hair piled onto a desk. Snoring could be heard. I did what any good boyfriend would do and shouted, "ANNABETH!"

Annabeth shot up and threw a knife at me. It went through the message (on her end) causing the image to distort and I'm assuming impaled into something I couldn't see.

She glared at me, "Perseus Jackson, you are an insufferable seaweed brain and if you were here I would have tackled you to the ground and kicked your little behind for being an annoying jerk."

"I love you too." I gave her a lopsided grin. "I didn't mean it, honest. Besides, you couldn't kick my little behind. I'm invincible remember?"

"You told me where you weak spot is remember." She answered back cheekily.

"Hey, being snarky is my thing." I stuck my tongue out and she laughed.

"It's so good to see and hear you seaweed brain. I miss you. I heard that you were sent on a quest."

"It's not really a quest. I didn't receive a prophesy so I feel like this is more like a mission."

"Oh? How is the mission going?"Annabeth asked.

"The people are really nice. I'm staying with the Weasleys. Mr. Weasley loves anything to do with muggles. It's what they call non-magical people. Mrs. Weasley reminds me of my mom, although she has fiery red hair to match her fiery personality. Bill is, from what I understand, works at a bank as a treasure hunter? Charlie works with dragons. Percy is really into cauldron bottoms, he's more proud and annoying to be around than you are, Fred and George are the equivalent of the Stoll brothers, Ron loves Quidditch, I don't know what that is, and Ginny is a super sweet girl, but she can be as fiery as her mom. I hope I'm not forgetting anyone, there are a bunch of them. There is also Hermione. You two would really get along I think. Harry Potter is here too."

"He's the one you are protecting right?"

"Yeah. I'm not sure from what. Nothing has happened so far, but knowing my luck everything will go down hill. They are also all so curious. I barely got by today with keeping my secret. I'm afraid that the cover story I was given is just barely passible. I don't know anything about this Ilvormorney school. It'll be hard to keep my cover if they keep asking questions."

"You know, there is something you could to fix that. Research."

I gagged and gasped in mock terror. "I'd rather take my chances vaguely getting by."

She raised her eyebrow, "Percy..." Before she could go any further with an explanation, I asked her about her plans for Olympus. She launched into a whole use if words I don't understand. She had a huge smile on her face and that made my heart flutter a bit. It was nice seeing her smile again. After the war she had bad nightmares too and she wouldn't smile. Being on Olympus and doing what she loves has really helped her. So I didn't really listen, but I smiled and nodded along like I was. After she was done, we talked about our day and then said goodnight. Well, goodnight for me. Time zone difference.

I IMed my mom next. She wasn't very happy that I was gone again, but she was glad that I was alright and being taken care of. She told me to be safe and all that. We said our "I love you"s and ended the message.

I made my way back to Ron's room.

"What took you so long? Ron asked. Suspicion was laced in his voice, but his face showed nothing so I thought he was joking.

"Oh, um," I had to think of something quick. "I'm lactose intolerant. Eating that icecream made my stomach a bit upset. " I silently slapped myself on the inside. What was I thinking? Lactose intolerant? Now I won't be able to eat ice cream or drink milk without revealing the lie. I scowled at the thought.

Harry and Ron looked at each other with expressions I couldn't read.

"Is everything alright guys?" I asked.

"Yeah, sorry. Everything is fine. Sorry we gave you ice cream. We didn't know." Harry said.

I smiled. "Don't be. I enjoyed it anyhow."

With that we got ready for bed and then turned out the light.

*****Linebreak*****

The next morning, we had a quick breakfast of bacon and eggs and then we were off to Diagon Alley. I started to walk to the door when everyone else walked towards the fireplace.

I followed them with a confused expression. My confusion deepened when Mrs. Weasley gave everyone dirt.

Ron looked at me, "Haven't you ever traveled by floo powder?"

"Never. I don't want to get sick. Why would you hold flu powder?" I asked.

Hermione giggled, "It's not flu powder. It's floo powder." All she did was hold out the "oo" sound on the second time and didn't help me at all.

Harry took pity on me. "You stand in the fireplace and you say the name of the place you want to go. Then you throw down the powder and you will be taken to that place."

I said something smart like, "Er okay?" I was still confused.

Mrs. Weasley asked Ron to go first so I could see. He stepped into the fireplace and held the hand full of powder out. He said, "Diagon Alley" and then threw the powder down. Green flames erupted, covered him, and then he was gone.

I let out a manly squeak. (If there even is a way to squeak manly. I was trying to make myself feel better) Mrs. Weasley then took my hand and guided me to the fireplace.

"Don't worry dear it's perfectly safe. Say Diagon Alley loud and clear."

I looked at the sand in my hand and then back at the others. They smiled reassuringly. I took a deep breath and said, "Diagon Alley." and threw the powder down.

Green fire erupted at my feet and suddenly I was on Olympus. It was during the war when Kronos was destroying it. Greek fire was everywhere. I heard his laugh and the sound of his wicked blade slicing through the air I shuddered. The last thing I remembered was the cold feeling his shrill, maniacal laugh still haunting my ears and then black.

So there you have it. A day late I might add, and I am sorry for that. I do plan on updating regularly and set a time frame in which I should update, but sometimes that may not happen. I will update though. I am so excited for the next chapter! I have some exciting things to come. It's been a slow start, but it's starting to pick up now. I don't know about you guys, but I am excited for what I have planned.
