(I don't own PJO.) In the next few chapters, I won't be writing in Percy's POV due to the fact that I can't speak horse.

December 16-17

Nathan's POV

Black fur sprouted from Percy's wrists up to his face. I started thinking that he was turning into a donkey from Pinocchio, but the hair was a lot thicker and the ears were shorter. I stood in horror, and possibly with my mouth hanging half open, of the black stallion laying on the cabin floor in front of me.

Suddenly, Michael tripped me and my head hit the wood of the Poseidon cabin. My vision turned blurry and I must've hit a nerve because my body felt numb and tingly.

"He won't remember what happened," I heard Jason say; "A good whack to the head will cause memory loss. Isn't that great, Michael?"

"Totally!" Michael picked up a cricket bat. He raised it above his head and I found myself muttering a prayer to Zeus knows who.

Annabeth's POV

The conch horn sounded for bed and we trailed back to our cabins. It was getting late anyway. Once everyone was in their cabins, I was the last one in the cabin area.

"Where's Percy?" Jennifer asked me. She was walking by me the whole time and I hadn't realized it.

"Oh, um... I saw him walk towards the cabin area a few minutes ago. Why?" I asked. Jennifer stopped in her tracks and gasped. I turned my head to see what was lying on the ground next to the Poseidon cabin: Nathan's unconscious body. Why didn't people notice him before?

She ran up to him and knelt, "What happened to him?"

"I'm not the detective around here," I said, standing over her. The doors of Percy's cabin opened and... a black stallion was standing in the doorway?

Jennifer slowly stood, her face was totally confused, "Whaaaaat?"

She stole the words right out of my mouth. Then I caught something very unnatural to horses. His eyes were deep green like the sea. The horse looked down at Nathan's pale body and nuzzled his hair. I stepped back warily.

"C'mon Jennifer," I warned, "He could have rabies for all the gods know."

She backed away and I grabbed her hand, pulling her into the Athena cabin. The last thing I saw was the horse's green eyes. Slamming the door, I turned to the rest of the cabin members.

"What was that?" I irritatingly asked. Everyone started staring me and Jennifer, though I didn't feel uncomfortable.

"Um..." Jennifer started, "A horse?"

"No, it was something different. Something about the eyes."

"I was too busy worrying about Nathan," she hauled herself up to her bunk. I decided to drop the subject and forget about what just happened by getting dressed for bed.

"Someone knocked him out," Jennifer stated, "And I swear I'm going to kill Michael and Jason if they did it."

...

The next morning, Chiron said that Nathan had been placed in the infirmary for head trauma and I've been starting to believe that Michael and Jason did knock him out. Though, I wasn't in the mood to argue since I haven't seen Percy all day. I asked a few of the kids around the arts and crafts and they said they haven't seen a single trace DNA evidence of him.

About that horse I'd seen last night, he's been staying in the forest, but whenever I come near, he tries to hide his face behind a tree. He doesn't show any signs of harm or anything. His eyes are really what caught my attention, and it's a surprise to me that Jennifer didn't notice it in the first place.

As for Michael and Jason, they were put on probation by Chiron in case of interrogation. Injuries aren't recommended during interviews, but when some people just don't answer truthfully, we beat the Styx out of them. Speaking of interrogation, I asked Chiron if we could do it to Jason to see if he knows anything about Nathan's head trauma.

"The horse bucked him," he explained. We were sitting at a table in the Big House, "We were able to alert Chiron but the horse disappeared. We haven't seen any signs of Jackson anywhere."

"You're lying," I firmly said. I can always tell when people are lying. It's a gift from Athena, plus Hermes children are prone to tell fibs to make up for thefts.

"If you don't believe me, ask Michael!"

"I already talked to him and he said the same thing. Spit it out or I'll use force."

And basically after that, he started arguing with me and trying to change the subject. Chiron, in wheelchair form, rolled in from the kitchen, "Nathan is up, if you want to see him."

"Thanks Chiron," then I turned to Jason, "We'll talk later."

Once I entered the infirmary, I found Nathan propped up in bed while holding an ice-pack to his head.

"Hey Annabeth," he groggily said.

"How's your head?" I asked, walking over to him.

"I can't remember anything from last night. Chiron said it might be amnesia."

I sighed, "It might be. You got a pretty good bump on the head there."

Nathan touched the bruise on his forehead, but then he winced at it.

"If your memory comes back," I stated, "Notify me."

"Yeah, sure."

I left the Big House and made my way towards the forest after sword practice. As usual, the black stallion was there, still hiding his face behind a tree. Slowly walking up to him, he huffed and turned his face to look at me. The horse trotted close enough to me where I could touch his nose.

Curious, I raised my hand to feel the soft fur, and a shock went through me like I'd just been electrocuted by Thalia. A familiar voice appeared in my mind.

Annabeth, it desperately said, What am I?

Since no one else was around, I spoke aloud, "A.... horse?"

The stallion's sea-green eyes widened and he stepped back.

"Wait," I told him, "Who are you?"

I knew that water jug was enchanted! It was Michael and Jason's fault!

My hand dropped from his face as I stepped back. The voices stopped fuming through my head. I could tell that my face showed confusion. I could tell that was Percy's voice.

I know! I know it's a short chapter. But hey, I had a little bit of Writer's Block (GASP!). If anybody cares, send me ideas via review and I'll give you virtual cookies!
