When I got to her cabin she was in the arms of someone I never expected to see, especially not here. It didn't make sense but at the same time the pieces of this mysterious puzzle were falling into place.

"Percy? What are you doing here?"

"What's he doing here?!" I pointed to the tall skinny blonde son of Hermes that had his arms wrapped around her. He should have been dead, I saw him die. Yet here he was, standing in front of me like the Titan War had never happened.

"Hades owed me a favor; I thought it was time to cash in."

"But that's Luke Castellan!"

"Um Aero, who is this guy?" It was the first thing Luke had said since I entered the cabin, and it struck me as odd, since he knew exactly who I was.

"Luke, this is Percy Jackson, son of Poseidon. You've already met him though; remember what I told you about the amnesia. You hit your head and forgot a lot of stuff."

"Right, you did say that." I heard the soft giggling of Lukas as he entered the cabin and Luke scooped him up. "There's my little man. I could never forget you"

"So Luke is Lukas's father?"

"It shouldn't have taken that long to figure it out Percy."

"How is this possible?" she took my hand and led me to the door of the cabin.

"Luke I'll be back in a few minutes, I have to discuss something with Percy." I saw Luke nod to her as she led me out. "I already told you Hades owed me a favor."

"Hades owed you a favor, and you decided of all things to bring Luke Castellan back from the dead?"

"I love him Percy."

"But he tried to bring Kronos to power and over throw the gods."

"What Hades brought back was the Luke from before, before he was a part of Kronos's plan"

"Can Hades even do that?"

"Percy, Luke wouldn't be here if the King of the Underworld couldn't do that."

"That's why he didn't know me isn't it?"

"The Luke from before didn't, Percy, so this Luke doesn't know you. He doesn't know about anything that's happened in the past couple of years. He doesn't know about the Titan War, or his part in it."

"You can't hide it forever though; so many people he knew have died he's bound to notice."

"Don't you think I know that Percy?!" The next thing she said I don't really think I was meant to hear. "If Octavian hadn't been here to help me heal him, he might not have even made it back."

"Octavian? Is that the blonde boy I saw you with at dinner? The one you were speaking with in that weird language?"

She sighed "Yes Percy, that was Octavian, and we were speaking Latin."

"You know Latin?"

"Percy, when you live as long as I have, you learn a few things."

"So who is he?"

"My cousin."

"You're cousin?"

"Yes he's my cousin, well sort of, he's not really like a direct cousin, but he's family anyway, I just call him a cousin so it's not all complicated and junk."

"Well that makes since, Greek families tend to get complicated." I smiled and chuckled. By the time we walked back to her cabin Lukas and Luke had fallen asleep on the bed that, I hadn't noticed was there before. "Aero, I have something I want to ask you about. The other night, before I even met you, I had a dream about you. How is that possible?"

"Hmm. Well you have a psychic connection with Grover. Maybe it's the same thing?"

"So you don't know what it means either?"

"No, but if it's there it's there for a reason. You and I are connected, like a tide pool."

"A tide pool?"

"Yep. The gravitational pull on the seas caused by the moon. That's actually just a tide but tide pool sounded better." She laughed

"I still don't get how that relates to us."

"The moon and the sea, Percy. I am a daughter of the moon, and you are a son of the sea."

"Oh well that makes sense I guess."

"We're unique. One of a kind."

"Well there are other sons of Poseidon, I'm not that unique."

"Well, I guess that's true, but how many of those children are mortal Percy, how many of them are human."

"I don't know."

"You're his favorite."

"What?"

"Poseidon wanted to become mortal, and stay with you and your mother. It was the big gossipy news when you were born." She smiled. "Get back to your cabin Percy. It's late."

I nodded and walked back to my cabin. I laid there listening to the ocean waves hit the beach. I also heard the soft sound of a flute playing. I felt I had heard the music before, but didn't have time to think about it because the music had lulled me to sleep.

The next day things got even weirder. I went to breakfast and found Aero there, with Luke. No one seemed to be bothered by the fact that he was here. Except for Annabeth, she seemed overly bothered by it

"She's messing with the Fates, Percy. How can Hades just bring him back?"

"I don't know, maybe they owed her a favor too?"

"Owed her a favor? That's how she did this? Hades brought Luke back because he owed that stupid moon girl a favor."

"Annabeth maybe you should just calm down."

"Why do you keep siding with her? Maybe she should be your girlfriend and not me!" She stormed away to the training arena. I looked over at Aero; Luke had taken Lukas somewhere, which gave me the opportunity to ask more questions.

"What did you do for Hades?"

"What?"

"What favor did you do for Hades so that he owed you?"

"I looked after his kids."

"His kids?"

"Nico and Bianca di Angelo."

That took a second to register in my brain. She couldn't possibly know the di Angleos. Could she? "You know Nico and his sister?"

"Didn't I tell you I spent time in the Lotus Casino Percy? How else could I still look this young after all these years?"

"You are very mysterious."

"Really Percy? No one else seems to think so." And with that statement she left the table.

Why did she intrigue me so much? I couldn't get her out of my head after what she said about the tide pools, and this morning had just made it worse. She was so mysterious, but what she had said about no one else thinking so made since. I haven't seen anyone else question why she's here or who she is. After careful consideration, which was really hard to even get considering I'm ADHD and got distracted while thinking about it, I decided to ask Chiron, so I walked to the Big House. Much to my displeasure Aero was also there. How was I supposed to ask questions about her if she decided to show up there too? It looked as if they had been arguing about something, and I think I might have heard her say something about Hera. As she left the Big House, I noticed a thin silver flute attached to her belt. 'So that's what the music had been last night.' I thought as she walked by me. Although her personality had changed, she seemed more hostile than she had this morning, and she had this look of pure terror on her face. The kind of look you only get after seeing the Oracle. When she noticed me noticing her, she looked scared, but scared for me, like maybe the Oracle said something would happen to me or something. I went to bed that night thinking about how much pain she seemed to be in.

I woke up surrounded by wolves. I had no idea where I was, or even who I was. I could only remember two girls. One of them had a name, Annabeth, but the other only a face. Her silvery blue eyes, gave her this pained expression.
