Percy's POV (that's new, ain't it?)

"I'm leaving," were the first words I heard out of Mira's mouth as she walked into our shared cabin. I looked up at her from my place on the floor where I was polishing Riptide. It didn't really need it, but it was relaxing for me, especially when thoughts of Tartarus flashed through my mind.

"You what?" I asked, knowing what she said but hoping I was wrong.

"You heard me. I'm leaving," she crossed her arms in that stubborn way of hers. I stood up, capping Riptide and slipping the pen back into my pocket.

"Where, exactly?" I asked, narrowing my eyes.

"On a quest. With Jake," she answered, jutting out her jaw defiantly. My eyebrows shot up as I crossed my arms as well.

"No, you're not. You know how dangerous they are. You're not going," I said, glaring slightly. I was protective of my little sister and everyone at camp knew it.

"I have to go! We got the prophecy. A child of Poseidon has to go. Rachel said child of the sea and child of Aether along with a guide must go on a quest," she argued, glaring back at me as she moved her hands to her hips. I knew that move. It was the same move Annabeth made when she had her mind set on something and there was no point arguing with her. I thought for a second, looking for a loophole. All prophecies had them.

"Child of the sea? She didn't say daughter, right?" I asked, smirking. Mira's eyes widened as she realized what I was saying.

"You're not going. He's my best friend. I'm going," she huffed angrily.

"Too late," I said, slipping out the door of the cabin and taking off towards Jake's cabin, hoping the little twat was there. I heard footsteps pounding behind me before stopping as I heard Mira shout something about not coming back behind me. I didn't look back. Instead I picked up speed until I reached my destination and slammed open the door, not even bothering to knock. I spotted Jake lying on his bed, staring up at the ceiling. My intrusion didn't even seem to faze him. He must've been too deep in thought to realize I was there. I grabbed the front of his shirt and roughly pulled him up. Let's just say I wasn't really too happy with the kid.

"You're not taking Mira on whatever little quest you have. I'm going. You can't protect her, so she's going to stay right here where she'll be safe, got it?" I growled, my face only inches away from his. Jake didn't seem all to surprised by my hostility. He simply nodded and I released his shirt, letting him fall back on the bed. (A/N: I really love writing protective Percy, sue me.)

"I figured you'd be here sooner or later. I wasn't planning on taking Mira. Two inexperienced demigods on a quest where someone is not going to return? Not happening. I'm not an idiot. I know it'd be better to have you there. You've done this before," Jake said, shrugging. My eyebrows shot up for the second time that day. So the kid was smarter than he looked. Good.

"So we've got a deal?" I asked, holding out a hand.

"Deal," Jake said firmly, shaking my hand.

"Good. And hey man, sorry about all that. She's my baby sister. I'm protective of her," I said, scratching the back of my head and grinning sheepishly. Jake smiled easily back.

"It's cool dude, I'd be the same way. It's Mira, after all. I want to protect her," he said. Maybe I'd judged him too harshly. It seemed he only wanted what was best for my half sister. I nodded, flashing him a smile.

"Thanks bro. You're good to her. If you ever hurt her though," I trailed off, leaving the threat hanging in the air. Jake nodded in understanding and I gave him a wave as I took my leave from the cabin. I stopped on the porch when I saw Mira there waiting for me, a scowl on her face. "You're not going," is all I said. She huffed and pushed past me into the cabin. I heard her and Jake exchange quick words before she groaned in frustration and the door was once again thrown open, an angry Mira storming out. I sighed softly, wrapping my arm around her shoulders and giving them a soft squeeze. "We're just trying to protect you," I said. She sighed and nodded in understanding. I smiled at her softly and led her back to our cabin, arms around each other's shoulders. I knew she wasn't happy, but I also knew she was a smart girl that, deep down, knew what we were doing was best for her. I kissed the top of her head as we reached our cabin and released her from my hold. She climbed into her bed and flopped down, face buried in her pillow. She needed time so I turned and silently left the cabin, giving her space.
