Connor and Travis hold Percy back as he trying to follow Cacy.

"Don't..." Connor says, panting.

"She likes to be alone." Travis adds.

"Well, how do you know if you never try?" Percy basically yells.

"Seaweed Brain" Annabeth says "You should listen to them. They are at the same house with her for more than six years. If she has a hiding spot, that means she doesn't want to be found."

"But..."

"Hate to admit it, but this time, I think she is right Percy" Nico says. "I know when people wants to be alone. I have been in that sittuation for a couple times."

Percy exhales, then sits down. He looks at Chiron, waiting for an explanation, but the old centaur seems as confused as him.

"Soooo... Let me get this straight." Rachel says. "Poseidon has just claimed this girl, Cacy right? a daughter, which means she is Percy's half sister, right? And I know she is a child of the Big Three and a powerful demigod and Poseidon had broken the oath again and all that but why are you so serious? The Prophecy is done. There will be no more threats for a while. So why every one is basically freaking out?"

"Clarisse throws a glance at the new Oracle:

"You don't know a thing, don't you? Miss Oracle suppose to know these, aren't you?"

"Well then" the red head girl shrugs "Tell me about it."

"She is kinda a misfit." Katie Gardner says. "Even though she has been here since forever, as I heard, but still she is different from us. I think she hopes that when her godly parent claim her tonight, she can finally find a new family, a new life. I guess being a child of the Big Three isn't on her plan."

All the Camp look at her, silent.

"What?" she says defensive. " I do talk with her, okay?"

"But how in the name of Zeus..." Travis says

"...can you actually have a conversation with her?" Connor adds.

"You guys are so unbearable!" Miranda exclaims. "Me and Katie talks to her some times. But you have to start first! She is a sweet person."

"But she just nods or shakes her head or silent every times we try! Luke tried to, and she ignore him! And he was so friendly that no one can ignore him." Chris says and Annabeth starts to shake at the name of Luke, and Percy shoots him a death glare, while holding Annabeth tight.

"Because she didn't trust you yet!" Nico suddenly says "So she wouldn't talk to you! Idiots!"

"Hey people!" Will Solace yells "I thought that we are talking how to calm her down? How can we calm her down if we are fighting? And discussing about her past behavior isn't the right thing to do now."

"Oh shut up you little sun." Clarisse says, obviously isn't over the whole chariot thing. "You don't even know her.

"Oh do you?" Pollux jumps in "You doesn't even give a dam about her!"

"ENOUGH!" Chiron yells. "Stop this. We'll talk about this later, in a council at the Big House. Now, go to your cabin. Camp fire is over. And Percy? Don't push her. She can't handle that."

Percy signs. He gives Annabeth the goodnight kiss and head back to his cabin, not sure how to feel about his new sister.

Cacy destroys everything on her path. Trees, bushes, small animals and some monstes. Her twin daggers become the most dangerous weapon for any ones who dares to come near her now. The tree nymph are cursing her, but she doesn't care. She runs to her spot and burst out crying.

Normaly she doesn't cry out loud. Her tears just flown silently. But now she is sobbing loudly enough for the whole woods can here. She can't hold it back and she doesn't want to. Let the Harpies come to eat her. That would be lease painful.

Well done Aphrodite, well done. Her own brother! She falls in love with her own brother, who is the hero of Olympus (sort of), and have a beautiful, smart, and likable girlfriend. Heck, Annabeth is her idol!

And being a child of Poseidon... She can't even think about it. This cannot happen. How can she be his daughter? He broke the oath twice! She shouldn't even exist! Now for all the rest of her life she will be compare with Percy Jackson, and she knows that Poseidon only claim her because he has to. She is a shame. That's why he didn't claim her. He doesn't want her. Since she was born, her father doesn't want her.

She falls into the hardest sleep ever, with all of her crushes come to haunt her in the dream.

The Iris message fade before Percy's eyes, and Tyson vanishes. Percy has just calls his Cyclop half brother and told him about Cacy. Tyson seemed very excited of having a sister, and he told Percy to tells their new sister that he say hello. He just nods.

To be honest, he doesn't like this. Obviously Poseidon wasn't kidding when he told Percy that he may get a brother or sister soon, but Percy never thinks it is this soon. He feels worried.

What if she is more powerful than him? What if she suddenly becomes the hero and people forget about him? He knows that he doesn't want to be a hero, but deep inside his mind, he has to admit it was pretty cool to be the hero. Rachel has spoke the second Prophecy, which starts with "Seven Half-Bloods answer to the call". He wonders if she is one of the seven...

And what if she hate him, or he hate her? That would be the disaster. And if she try to come between he and Annabeth, like an annoying sister? He would kill her then.

And what about his mother? What will she say then, knowing he has a half sister? And doesn't Poseidon love Sally so much? So why, after just three years, he can have kid with another woman? He knows that Poseidon is a god, and they are always be like that, but still... Ever since he knows the truth about him, he always thinks that Poseidon loves her and only her. Heck, he even break his oath because of her. But thinking he did the same thing with another woman, just three year after his mother... He can't stand this.

When he falls asleep, a thought came to his mind. When Chiron knealed after Cacy has been claimed, he just said "Hail, Cacy...". And Percy has never heard of her last name before. So what is her last name? And what is the story of this strange girl, now his sister?
