Percy Jackson and Annabeth Chase (Percabeth)

I paced around my cabin. It had been lonely in my cabin since Tyson left. Lonely, and messier, now that he wasn't here to clean like he used to.

I was thinking about whether I should at least attempt to tidy up my floor (which wasn't completely visible right now) when I heard the door creak open.

I jumped, because no one else at Camp Half-Blood lived in the Poseidon cabin, and then turned around to see… no one. I turned back around, figuring that whatever opened the door would show it's self soon enough.

Something hit me in the shoulder.

I whipped my head around in every direction, uselessly trying to figure out what type of angry animal had crawled in here, when I heard laughing, coming from my bed.

Annabeth.

I walked over, waved my hand around in mid air a few times until I was able to find her head. I took off her hat.

There was Annabeth, her hair ruffled, and a smile on her face.

"You should've seen yourself, Seaweed Brain." she said, still giggling.

"Haha, very funny." I said, trying not to let my smile show.

We had been trying to see who could play more pranks on each other. Annabeth had the advantage of her invisibility hat, and I had the advantage of her being afraid to go near water fountains and sinks, in case I was lurking around to give her a little face-wash.

We walked out of my cabin, playfully threatening each other about future pranks, when Clarisse heard us.

"What're you guys talking about?" she asked. I wasn't sure if I wanted to invite her to a prank war when she was holding her new electrical spear.

"Well…" I said, thinking of what I could say without actually telling her.

"We were talking about a pranking competition we were having." she said. I shot her a "thanks a lot" look, which she didn't seem to see while she was glaring into Clarisse's eyes.

"Prank war?" she asked with a smirk on her face. "Like you guys know how to do real pranks." What she said, mixed with a malicious sound in her voice that I new would bug Annabeth, made cautious of what Annabeth might say in response. I was hoping it'd just be something like, "You're so immature, if you think that we'd do anything more than have a friendly competition between each other, then you're wrong. C'mon, Percy." But no. Of course it wasn't.

"Clarisse, if you think you could do better, just say so." I didn't like how that sounded like a challenge. Even if it wasn't meant to sound like that, that's how Clarisse took it.

"I do think I can do better, and I'll prove it!" she said. I could only imagine what she had planned for us.

I was just about to say to her, "No! By prank war, Annabeth obviously meant a safe, fun game of hide and seek!" but she turned around and strode away, in steps so big I'd have to run to catch up with her.

I slowly turned to Annabeth. "What-" I said, emphasizing each letter, "did- you- get- us- into?"

Annabeth wasn't looking at me, though. She was still watching Clarisse's back walk away. "If she thinks she's so great at pranks, I'd like to see her try against us."

She turned her head to me. "We've got planning to do." She grabbed my hand, and dragged me to her cabin.
