Stheno, Euryale and Medusa!

Percy's P.O.V

I stared up at the ceiling, bored out of my mind. Stupid ADHD. I heard someone coming and saw Thalia come in.

"May I speak with you?" She asked.

"Sure." She let out a shaky breath then tackled me. I instinctively tensed then I realised that she was hugging me.

"Thalia? What-"

"I know it's you Percy. You don't have to lie to me anymore." She sobbed, tears running down her face.

"You know? How?" I asked.

"I overheard you, Apollo and Artemis talking. Gods, I shouldn't have been so stupid to believe that you would've broken up with Annabeth!"

"It's okay. It's okay." I soothed her. I didn't realise I was in human form until I noticed myself stroking her hair.

"I'm so sorry." She said.

"It's all right. Pinecone Face." I added. She laughed slightly and wiped her eyes.

"We better go and help them pack." I said and shifted into a wolf again. We walked out of the tent together and saw the hunters almost done packing.

"Wow. That was quick." I said.

"Yeah, looks like we're ready to go."

"I'll go ahead and scout the area." I said and shifted into a bird. Thalia gasped.

"Y-you're a phoenix?" She asked in disbelief. I laughed and launched myself into the air. Feeling the wind in my feathers. Soon the hunters were far behind. I narrowed my eyes as I saw something. Another camp. I flew over it and saw people, guns in their hands. They don't look like demigods though. Then I saw someone who almost made my heart stop. Krios. Then I realised that it wasn't a demigod camp, it was a mortal camp.

"Oh no." I muttered. I glided down until I was in hearing range. Krios was speaking to the mortals.

"-and when those pesky hunters of Artemis come this way, we will kill them!" He shouted. I quickly flew back to camp and landed in front of Thalia.

"Krios! He's here!"
