A/N So guys, new idea! I couldn't think what to write for my other story, so what's better than to write a new one? Please review and tell whether I should continue! Love you all!

Percy's POV

It all started with him. Nick. Deceptively vulnerable and scared when he arrived at camp, everyone's hearts went out to him. They wanted to help him, care for him. They were dazzled by his charm, his strength, his handsome face. I was the only one who sensed something else within him, but naturally, no one believed me. they thought I was jealous. And I admit, I was, just a bit. But it was more than that. There was something about him, something dark and twisted, and I hated him.

Of course, he was a great warrior. No doubt about that. And he was a fighter, a leader; the best hero Camp Half-Blood had ever seen, according to Chiron. It seemed to have slipped his mind that he had said the same thing to me not that long ago. Now, I was forgotten and cast aside. But you know the funny thing? I could have lived with it. I could have just accepted it, the fact that I was now unimportant and ignored. But that was before he did something I could never forgive him for. That was before he took Annabeth.

Annabeth. I feel sad just thinking about her. He took her from me, told her things that weren't true. And the worst thing? He's my brother. A Son of Poseidon, just like me. I just couldn't live with him anymore. I couldn't live with her. Seeing them everywhere; I couldn't do it. And so I did the easiest thing I could think of - I left. I disappeared off the face of the earth - and no one came looking for me.

Annabeth's POV

"Nick! What are you doing?"

I walk over to him, shaking my head. This is the second time he's sneaked off to the arena, to do God knows what. Who needs to train at 2 in the morning?

He gives a huge jump at my voice, and for some reason, has a half-guilty, half-angry look on his face. He looks sort of... shifty. He manoeuvres himself so he's facing me, but he's hiding something behind his back, and he's careful not to turn fully, so I can't see behind him.

"What are you doing, Nick?" I ask, sighing.

"Nothing. What makes you think I'm doing something? You don't trust me at all, do you? What's wrong with you? Missing that idiot, Percy Jackson? Percy, Percy, Percy. You don't even like me. I don't know why you choose to go out with me. Might as well just tell me it's over, right? Go on."

He says all of this very fast, and I stare at him in shock. But this is not new either. He's always saying stuff like this. But he's never mentioned Percy before. I want to cry just thinking about him, and that would not generate a great response from Nick, that's for sure.

"Go on!" he shouts, this time, and he steps forwards, so he's very close to me. He looks deranged. What the hell has happened to him? He was perfectly fine earlier.

"Nick. What are you saying? Why are you saying this? You know that I... love you." My voice chokes on this lie, and I try my hardest to cover it up. Luckily, he doesn't realise.

He suddenly looks upset, and grabs hold of my hand and kisses it gently.

"I'm so, so sorry, Annabeth. I don't know what came over me. I'm so sorry. It won't happen again. I love you. I love you. I'm sorry."

He gives me a soft kiss, and runs his tongue across my lips. But I pull away, and peck him on the cheek instead.

"I have guard duty, Nick. Not now." He gives an impatient huff, and gives me another kiss, with much more force than necessary.

I don't mention the real reason I don't want to kiss him. I don't mention that I'm imagining another pair of lips on mine. I don't mention that I'm thinking of Percy - of his perfect kisses and his perfect smiles, his beautiful green eyes and the way he made my heart beat ten times faster. Nick could never compare. I just wish I knew what happened to Percy. I wish I knew why I chose Nick, why I found myself kissing someone else. What did I ever see in Nick?

I remember when he first arrived at camp. He was gorgeous, and tall, and just like Percy, but even more hot. He was kind to me, and he was an amazing sword fighter. I remember thinking he was better than Percy, but now I can't think why I ever thought that. I've seen him fight, and he's even worse than Leo. He helped everyone, and Chiron made him camp leader, pushing Percy out of his place. I can't even remember seeing Percy, the last few weeks before he disappeared. I just remember that night.

Flashback

I've just finished looking over the new campers first sword fighting lesson, and I make my way towards my cabin. It's my birthday, but only Percy and Nick know. I'm so tired, and I just want to get to bed; maybe work on that new building blueprint I've been designing.

I reach my cabin, and am about to go in, when Nick emerges out of the shadows. He looks better than I'd have ever thought possible, and he's coming straight towards me, with purposeful intent on his face. His eyes are mesmerising, and I suddenly feel strange and faint - but I'm fine. I have only one thought. That I must be with Nick, not Percy. Nick is the one for me, not Percy.

I march up to him, and kiss him full on the lips. Half the camp is watching. I don't realise until it's too late that Percy has been standing waiting for me outside my cabin the whole time. He's even holding a present - I remember he hinted about that new dagger I'd wanted. He must have made it for me. But I don't even take it from him. I don't want to. My boyfriend has just seen me kiss someone else, right before his eyes, and I don't even care.

Flashback over

He'd gone the next day. We'd gone looking for him, but for some reason, it was very quickly determined that he was in fact, dead. Nick lead the group who looked for Percy. They'd come back in a few days, saying they'd found Anaklusmos lying by the side of a river, with a pile of clothes. It seemed he had drowned himself. Nobody questioned it. It's only now that I think - how could Percy, a son of Poseidon, who is god of the sea, have drowned? It's impossible, but we all believed Nick then. And what else could Percy be, but dead?

I feel like crying. If only he knew that I did love him - I do love him. Even though he's dead. I can't bear to look at Nick anymore. I'm about to turn away, when I see a gold gleam in his eyes. No, not a gleam. His whole iris blazes gold. The golden colour of ichor.

And I know that he knew exactly what I was thinking, and he didn't like it one bit. And I suddenly know, with alarming certainty, that Nick is not all he seems.

I give him a small, scared smile, before hurriedly making my way back to my post. I don't look back.
