Daughter of Poseidon/ Chaos

I meet Percy and a bunch of others

A couple minutes later, Percy was walking alongside Chiron. I wondered if he looked like me. I had nearly jet-black hair, sea green eyes, tan skin, and a bunch of other stuff I can't name. As he came closer, I saw he had jet-black hair, sea green eyes, and normal skin color.
I could actually see curiosity in his eyes. He was curious! Hilarious! I started to laugh. His face contorted to something between curiosity and confusion. "Why are you laughing? What is so funny?" Obviously he couldn't realize that he was actually curious about me. I laughed even harder. Then he looked like he was thinking of all the possible ways I could be laughing.
Finally I laughed so hard that tears streamed down my face. "So-Hilarious-you-were-curious-and-" I managed from my mouth. "You were laughing that hard because I looked like I was-" I cut him off with,"Thinking and curious," I managed while still laughing my head off.
Finally I calmed down and he showed me our cabin. I ran. He decided that I was racing him. Obviously he was out of practice, because I easily beat him. "I beat you!"
"I beat you inside the cabin sis!"
" I beat you to the beds!"
"Shut up, Percy!"
Yes, and we did that all the way to lunch. Everyone decided to watch us argue. Fortunately we were very entertaining, or everyone would've told us to shut up and eat our lunch.
