Let me know if the characters sound a bit OOC and give me some tips on how to correct my mistakes.

Percy Pov.
Today I feel like I can fly, but tthen again, only Jason can do that. Just because Annabeth's here, I feel like my old self. I can tell that the same goes for her. My friends who stayed here after the war are surprised to see me have such a fast recovery from my 'Annabeth Deprived State of Mind'. The only thing that seems to keep me going is her. While I was walking through the white tiled hall, I saw my friend Carter by my locker. He seemed surprised to see me with a wide grin. It's like he was seeing me for the first time, although he has seen me all year. Hmmm, maybe I am happier.
I had my arm over Annabeth's shoulder and she had hers around my waist. "Hey, man! Did you get ahold of some happy pills?" Annabeth looked at him with her calculating look, that can make just about anyone want to die in a hole. And lot of the school population, male and female, were staring at all of us.
I was like the one everyone thought was different from my first year. One year I'm all happy, the next is filled with depression. This was a side of me I've kept concealed."This man right here was the King of Depression. I'm surprised he hasn't tried to jump from a cliff yet." The thought that he said that made me want to laugh in his face, 'If only you knew!' I smiled at the thought and almost burst out laughing. Okay, I did start to laugh. Annabeth began to laugh just because I was, which caused us to have another round at it. "Hello? Earth to Percy." He said in a terrible walky-talkie voice. I stopped, composing myself to a barely contained giggle, and realized I was rolling on the floor with Annabeth. Blushing, I stood back up, holding my hand out to her. "Yes, psh, Percy to N.A.S.A. Over." He then began to laugh. "Now this is the Percy I've been waiting to hear all year."


Annabeth's Pov.
I feel like my issues have just melted away. I feel happier than Tyson with peanut butter, which is pretty happy if you've seen him in action. Percy start having a laughing fit after what his friend said. It was such a relief to hear him start to crack-up, that I started to laugh too. Soon we were both in a pile on the floor. "Hello? Earth to Percy." said his friend Carter. Percy of course had to have some sarcastic remark to follow."Yes, psh, Percy to N.A.S.A. Over." Carter began to laugh. Leo, who appeared while we were giggling, began to laugh to,"Perce, when did you cheer up?" Startled, I went for my knife, and held it against his throat. Percy had his sword out to his back. He winced. "Jeez, guys. No need to freak out. I know you had some tough times going through hell, but no need to go all ninja." He said this all in Greek. I replied in same manner, " Don't sneak up on us, or we might not check to see who it is first." "Yeah, we don't want a Leo-ca-bob. Make your position known before you come up behind us." Percy warned him. Leo nodded so fast, I was afraid it would bobble right off. "What are you guys saying?Is that Greek? Dudes, that's awesome! How do you guys know Greek?" Percy glanced in my direction as if to say 'HELP!'.
"Oh, er, one of our parents are Greek. Percy's dad, Leo's dad, and my mom." He replied with a very intelligent answer, "Oh, cool." His friend answered with an answer worthy of Percy."Why are you both pointing a ruler and a marker at his throat?" We removed our weapons. The warning bell rang. Saved by the bell. "See ya,Carter!" The three of us, Leo, Percy, and I made our way to our Greek lesson.


Carter's Pov.
Those students are strange. Sometimes I wish I can see into their brains to find out what makes them tick and not their front to keep to themselves. Annabeth told her goodbyes, but didn't realize that I had Greek too. I saw some of Percy's normal group and all the new students from Annabeth's school. They were all speaking in that language they knew and... was that Latin? Maybe they all have a parent not originating from America. I made my way to class, avoiding students with things in their hands and finally sat down my assigned seat.
