The training ground in the morning is the best place if you need some time alone.

Most of the time , there's no one here in the morning.

I was sitting there alone quietly , doing nothing and thinking nothing.

It has been almost a month since the camp started , and I just can't stop thinking about everything.

About Willy , my dad , the Primordial gods , the dream that I had.

I probably shouldn't be thinking so much about everything that's happening.

I just can't get rid of the feeling that I hate all the stuff that has been happening around me.

"Percy?"

I turned around and found Evan holding a wooden sword.

"Evan? What are you doing here?"

"Morning training , what about you? It's a rare sight to see anyone in this time of the hour."

"Right back at you , never seen anyone doing morning practice."

For those of you who can't remember who Evan is , he's one of Hades son.

His full name is Evan Song , and yes , he's korean.

He got a bit of a funny accent , that only those asian can have it.

"Well , if I ever want to get a quest , I got to polish my skill."

"Heh , trust me , an actual quest is not as fun as it sound."

"I know , but I want to make my father proud."

"Well... Good luck doing that."

Evan smiled , "Why the long face , Percy?"

"Nothing... Just have a lot in my mind."

"You should be happy , we won the game against the Hunters."

"I know , I just—

"I mean the way you and Willy work together. It's really awesome. I mean for all the long years I've known Willy , I never thought he could be that good. I knew he was a demi god , just never thought that he would be the son of Poseidon."

I raised an eyebrow.

"All the long years?"

"Yeah , Willy and I knew each other even before we got recruited to the camp. We knew each other for a really long time. Still , even all those years didn't change his habit of not liking to talk."He explained.

"So you're Willy's childhood friend?"

"Well , if you put it in a way , yes. But we weren't exactly close , since he never bothered to get close to anyone. Mostly he just shut himself from the world. I wouldn't blame him though , ever since that incident with his mother."

So Evan and Willy knew each other even before they joined the camp?

That's completely new to me. Then again , everything is.

"What happened to his mother?" I asked curiously.

"...That's probably not my place to say. You should asked him yourself , you're his brother after all. Besides , I don't know the full detail about the incident anyway."

Easy for him to say , I doubt he'll share that kind of story with me.

In fact , I don't think he'll share any stories with me at all.

"I doubt I can asked him about it , but thanks anyway."

"You're welcome Percy. Now I have to get back to my cabin , I promised my brothers that I'll do the chores today."

"Alright , see you later." I said.

He nodded , and walked away from the training ground.

So Willy and Evan are childhood friend.

Something happened to Willy's mother , that caused him to be like... This (according to Evan of course.).

Oh great , now I'm more curious about it.

All the more mysteries that I shouldn't be bothered myself to solved it.

This curiousity is killing me.

"Why the long face , Seaweed Brain?"

I looked to my back and found Annabeth crouching right behind me.

"Just had a lot in my mind."

"Please don't tell me it's about your brother." She pleaded.

"Half-brother." I corrected her.

"So It IS about Willy. Percy , you really need to stop thinking negative stuff about him."

"I'm not."

"You wouldn't be sulking like this if you're not."

"...I just..."

"You can't forgive your dad , you're angry with him. I know. But that's not a reason to be angry with your brother."

"Half-brother." I said annoyed.

"..You're sulking again."

"..I know... I'm sorry." I said apologetically

"Take a walk at the beach , think about what I've said and cool yourself down." She gave me a quick kiss , and walked away from me.

a-****-

I stroll around the beach , walking around doing nothing but thinking.

I thought much about what Annabeth said , and I calmed myself down.

Willy did nothing wrong to me , and like Annabeth said , I should really stop thinking bad stuff about him.

He is my half-brother after all.

I pick up a couple of stones and start to throw them into the sea.

"You're upset about something?"

I turned to me left side , and the very person I want to meet right now is standing there.

Poseidon , my father , he's there wearing a hawai t-shirt and a short blue pant with a pair of slippers.

"D-Dad... What are you—

"Something told me that you want to speak with me... I have something to tell you too."

"...Yeah."

"What is it?"

"It's about my half-brother , Willy." I said.

My father didn't look surprised , nor did he talk.

"... So you broke your oath twice."

"No , Percy. You're mistaken."

"..What do you mean?" I asked confused.

"Willy... He was an exceptional case. He wasn't even supposed to be here."

I stared at my father with confusion in my eyes.

"I was as surprised as you when I know he was here , I thought he was dead."

"That didn't explained why he's here , or why you didn't tell me about him!" I said angrily.

My dad didn't speak a word , he just gaze at the sea.

".. I know that you're angry." He said.

"I'm not!" I replied.

"But you must know that—

Hooonkk! A sound of a horn interrupted my father.

"... I must go now." He said.

"What? But we're not finished , I still have a lot to asked." I protested

"I know , my son. But Pontus requested my audience. I must meet him."

"Pontus?"

"I believe Artemis already told you about the Primordial gods. Pontus is the Primordial being of the sea , and now he wants to see me."

Before I could say anything else , a blinding light surrounded my father.

And at that quick moment , he dissapeared.

Oh great , I couldn't even get one clear answered from my dad.

I'm annoyed and there's nothing I could do about it.

I turned around from the beach and walk back to the camp.

a-****-

"Feeling better?" Asked Annabeth.

Annabeth and I were sitting at the dining table.

"More or less , I met my dad at the beach." I replied.

"What! What happen?" She asked.

I told her everything , but it's not much.

My dad really didn't tell me anything at all , just more riddles without answers.

"I bet you're thinking that your dad only gave you more question than answers."

I raised an eyebrow , "You really need to stop that , it gives me the chill."

"Stop what?" She asked innocently.

"Guessing of what I had in mind , and on top of that , being right of guessing of what I had in mind."

"You're just too easy to predict , Seaweed Brain." She smiled.

I couldn't help but to smile too , Annabeth really knows how to make me smile.

What she had to do is smile , and unconciously , I'll smile too.

I watched a few campers went to their tables.

Hades campers , Evan and his brothers.

The name Hades hit me in the head , now I have a question about them.

"Hey , Annabeth."

"Yeah?"

"Evan and his brothers , they're the child of Hades , right?"

Annabeth rolled her eyes , "Of course they are , Seaweed Brain."

"Evan is 16 , and his brothers is 13-15."

"Your point?"

"Then... Then doesn't that mean that Hades broke the oath when he had them?"

"You mean you didn't know?"

I shook my head in confusion.

"Apparently , Nico and Bianca di Angelo isn't the only child that Hades hide in the casino."

I was shocked , "You mean.."

"Yeah , Hades hides all his child in the casino in vegas. Hades only let Nico and Bianca out and he decided to keep hiding the rest of his children."

"So Evan and his brothers..."

"Born before World War II , yes." She continued.

Evan and his brothers were born before World War II.

Then that doesn't make any sense.

"Percy?" Called Annabeth.

"I-Im sorry , Annabeth. I need some time to think."

I rise from my seat and ran to the woods.

"Percy!"

When I was deep inside the woods , I stopped and lean against a tree.

Evan said that Willy is his childhood friend , and if Evan is born before World War II , Willy can't be his childhood friend.

Willy is still 17 years old , and he's not a god ,so he's not immortal.

It's impossible for him to become Evan childhood's friend.

Then again , Evan might mistaken Willy for the wrong person.

But that doesn't seems to be the case , Evan got the name , and the attitude right.

Everything doesn't make sense.

If Willy is Evan childhood friend , he should be 60 right now.

Unless... Willy isn't Willy.

My father said to me that Willy shouldn't even be here , that he thought Willy is dead.

It's starting to link together , the bad feeling I had about him , Evan stories , my father.

I was deep in my thought when I saw someone has been staring at me for quite some time.

A girl , in a bright yellow shirt.

She had a bright golden hair tied up in a pony tail.

With long jeans , and a pair of heels.

She looked young , in her early 20 years but she had the immortal kind of face , so it's a bit hard to tell how old she really is.

"You're still a bit faraway from the truth." She whispered with a gentle voice.

I was surprised when she whispered behind me.

I take a step forward and tripped.

I stared at her eyes , and it shocked me greatly.

It was shining brightly , with yellowly glow like a shining gold.

She stared at me with a cold icy look , as if I was some kind of a bug that she could easily kill.

I gulped , as she approach me slowly.

"How sad... Percy Jackson. For you not to realised the truth."

As soon as she finished saying that , she started to glow.

It was so bright that I couldn't open my eyes.

By the time , it was finished , she was gone.

I lied down in the woods , taking my breath away.

Oh great , another mystery.

I lied down closing my eyes , without realising that there's someone watching me from the shadow.
