Accidents Happen

Percy's POV

I watched as the golden sun set across the sky. At the moment, I felt horrible. I felt as if the whole camp was mad at me, which they probably were. The ocean waves splashed my ankles as I stood in the water, deep in thought. I was interrupted by a loud "Eh-hem" behind me. I was expecting a mad Ares camper, but I was relieved to see Annabeth when I turned around.

"Hey Seaweed brain." She said, her voice soft which seemed to make me feel better.

"Hi." I said flatly, my voice dull and emotionless. My eyes returned to the sea.

"Percy, the whole camp knows it was an accident. Demigods always cause trouble."

"Yup, well, they're still mad at me."

"Not many people are mad at you..."

"Annabeth, I kinda destroyed the entire Ares cabin!"

"It was an accident-"

"A little Apollo girl that was near the cabin is in the infirmary because of me!" (A/N: He caused a mini earthquake, a the cabin landed on the girl.) I said, silent tears streaming down my face, hopefully unnoticeable. It wasn't just because of that little girl that I was crying.

"Percy," Annabeth said, noticing my tears, "I know you're upset because of you mom passing away,too , and I understand that it was wrong for Clarrise to be picking on you while you're so... emotional, but you can't start thinking everything that goes wrong is your fault. You can't help doing stuff when you're mad... same with any other demigod."

I sighed. She had a point. There was no use arguing with a daughter of Athena.

"Let's go get dinner." she said, leading me to the Pavillion.

Clarrise's POV

I was fuming. My entire cabin was gone - of course it was being rebuilt and was going to be done by the night, but Jackson was gonna pay. I kinda felt bad for the kid, losing his mum and all, but he didn't have to be such a prissy about it. I saw him and the smart a** walking towards the pavillion, his eyes red and puffy from crying. He was such a wus.

"Jackson!" I called out in rage. Just seeing his face angered me. I could see his face was full of guilt. He silently walked past me, but I grabbed his arm just in time. "Jackson, I swear if you mess with me or my cabin, you will end up like your mother. Dead." I said, giving him a punch which did nothing, his skin like iron from the Achilles stuff.

He gave me a look of hatred and took out his pen and uncapped it, out came the three foot long bronze sword. I could tell he was about to slice me open with the sword, but he noticed people were watching. He capped the pen/sword, and ran.

"Wait Percy!" The wise s*** Annabeth said, and took off after him. People started gathering around me.

"Are you okay?!" Chris asked.

"I'm fine." I growled through my clenched teeth.

"Well it's official. Jackson has gone crazy and wants to kill the Ares kids." My half-brother Paul said.

"Like he could!" I snorted. My siblings laughed in agreement.

Percy's POV

The moment I had heard Clarrise mention my mother, I wanted to rip her heart out and make her eat it. Ever since my mom passed away, -You could say she got killed- my emotions have been uncontrollable.

I ran to my cabin, Annabeth right behind me.

"Percy!" she said when. We got in.

"What?!" I practically yelled, mad at myself and the world.

"Are you okay?!" She said, pulling me into a hug and kissing my cheek. I noticed I was shaking head to toe, and tears were streaming down my face.

"Yeah.." I whispered.

"You should go talk to Chiron... I think you need some help." She suggested.

"What, do you think I'm a crazy, mental freak like the others do? Unstable maybe? I heard what the Ares kids said." I snapped.

"No, I don't think you're any of those. I just think you're a bit depressed because of things going on."

"Whatever." I said not noticing the rude tone until after I had said it, "I'm going away, I need a break from all of this."

"Percy, let me come with you..." She pleaded, probably thinking that I was going to do something stupid.

"I'll IM you every night, ok?" I said, starting to pack money, drachmas, Ambrosia (not like I'd need it.), and some spare clothes. Annabeth stood there, motionless and speechless, no doubt nervous that she wouldn't see me again."I love you..." I said, kissing her forehead. I could hear her mumble a barley audible I love you. I walked out to the stables hopping on blackjack.

Yo boss, where to? He said.

"London." I said, shaking. I didn't understand my emotions, and I regretted leaving as soon as we took off, yet I didn't have the strength to turn back.
