Ella's POV~

I stumbled back and stared at my friend in horror. Her face twisted into an expression of hate that I never want to see there again. "Alive again." She hissed in an unfamiliar voice. "Thank you mistress."

"Cas!" I gasped. I tried to move forwards, but Annabeth grabbed my arm.

"No, don't." She said.

"But-" I started, but there was definitely something weird with Cas. She drew her sword and shield and scowled at us.

"Its an eidolon, Ella." Percy said. "You know, dead guys that possess people?"

"I can't get it to leave." Nico said, focusing on Cas.

"I'm not going anywhere." Cas's new voice hissed. "I shall kill you all in the name of our mistress. After all, you can't fight me. You don't want to hurt poor Caspian do you?" It twisted its expression and did a bad impression of Cas. "You wouldn't hurt me would you?" He, she, it, whatever, laughed.

"We can't fight it." Percy said. "We'll hurt Cas."

"We have to." Annabeth said. "We have no choice." Zombie Cas charged, sword raised. I jumped to the side just before she skewered me. Nico drew his stygian iron sword, and Cas seemed to wince a little, but Cas sidestepped and knocked it out of its hands.

"Cas stop it!" I shouted. "I know you're still in there - fight it." Suddenly, the gold light faded from Cas's eyes and she looked stunned and confused.

"Ella?" She said, breathlessly. "Help me, he's too stro- Ah!" She doubled over, and when she straightened up, her eyes were gold again. "Stay down, child. This is my body now." Zombie Cas hissed.

"How can we help her?" Biron asked. I was surprised at the level of worry on his face.

"Maybe if we just knock her out." Nico said hopefully. Unfortunately, Zombie Cas wasn't going to wait for us to figure it out. She charged Annabeth, and Annabeth barely managed to avoid the blade. Cas jumped onto the table and pulled out her javelin. She threw it, and it stuck in the ground between my feet.

I fell on my back and Biron pulled me to my feet. "Close one." He said. Cas leaped off the table and attacked Percy. He had to defend himself, but Cas was pressing him backwards.

"Cas, you have to fight it." I shouted, but she ignored me. Percy disarmed Cas, who screamed in rage and grabbed him by the neck. Annabeth tried to pull her off him and Nico fished his sword out from under a plastic table. Meanwhile, the mortals had finally noticed what was going on and were screaming and streaming out of the food court. Security guards were pushing them out the doors. We only had a few minutes before we got arrested.

"Okay, I'm really sorry Cas." I said. She turned towards me, confused, and I ran at her, bow raised. I cracked it over her head. Her eyes rolled up in her head and she collapsed. "Sorry." I repeated.

"Put down the guns and put your hands in the air. No sudden moves." A gruff voice said. It seemed the security officers had finally bucked up their courage to confront us. And apparently, they thought we were holding guns.

I turned. Sure enough, a dozen people in blue uniforms had tasers and stun guns pointed at us. I set down my bow and raised my hands. Everyone else did the same, except for Cas because, duh, she was unconscious.

They cuffed us and dragged us over to the police station where they put us in a holding cell. I banged my head against a bar and sighed. "Now what?" Biron moaned.

"I'm hungry." Cas said suddenly. "And where are we?" She was sitting up, rubbing her head where I had hit her. "And why does my head hurt so much? Weren't we in a mall?"

"You're okay!" I hugged her.

"Ow, OW!" She said. "Ribs hurt."

"Sorry." I said. "You were possessed by an eidolon." It took a while to explain that. Then we started thinking how to escape.

"I could just, you know, shake open the wall." Cas suggested.

"No, I have a better idea." Biron said. "But I need my bag." He pointed to the table in the hallway that connected to our cell. On it was our stuff.

"How can we reach it?" I wondered.

"Theres a water fountain over there." Percy grinned. "No problemo." He held out one hand and focused on the fountain down the hall. In no less then a second, a pipe burst underneath the water fountain, sending water streaming down the hall. He focused on it, and it blasted Biron's backpack off the table and across the floor. Biron lay on his stomach and grabbed it.

He pulled it up to the bars and pulled out the beaker of red jelly that he had shown me back at camp. "Is that the-"

"Yep." He unscrewed the top and a wave of smell hit me, like gym shorts and bad eggs. "Should be enough here for all of us to go once or twice."

"What is that stuff?" Annabeth asked.

"Potion I made. It lets you walk through walls. Its only enough for each of us to use once." He reached in and scooped up a fingerful. He popped it into his mouth and gagged, but handed me the jar. Then he did something amazing. He stepped right through the bars.

"That is so cool." Nico said. "But maybe we should go through this wall directly onto the street instead of through the office." Biron nodded and grabbed all our stuff off the table, then stepped back through the bars. It seemed to be more difficult to do the second time, like the bars were snagged on him, but it worked. We all shouldered our bags and passed around the jar. Biron had to take more, and in ten seconds we were ready.

I pressed one hand against the wall, and suddenly it just passed right through, like it was made of syrup. I stepped through and found myself standing in three feet of snow on the sidewalk.

The others joined me a second later, Biron holding the empty jar.

"Just a second." Cas said. She turned back, and I saw that our footprints in the snow lead directly from the wall. She crouched and wiped out the prints.

We took a bus to the edge of town, where I hijacked a mobile home. It was really pretty nice. There was two little cots, a bathroom with a shower, a kitchenette with a mini fridge and stove, a tiny breakfast nook.

Annabeth took use of the showers, Percy drove, and Cas and Nico napped in the two cots. I found a little food in the fridge and made us nachos. I really wished that Leo was there with his tacos, but I was a decent cook. Biron and I ate in the breakfast nook after I took a plate of nachos up to Percy.

"So." I said, leaning forward on my elbows. There was something I had wanted to talk to him about. His panic when Cas was in trouble at the mall was that of more then just a friend.

"So?" I glanced around to make sure that everyone else was out of hearing range or asleep.

"How about you and Cas?" He went from normal-colored to pink in less then a millisecond.

"We're friends. Thats all, nosy."

"Really? Because I spend way more time then I should with the kids of Aphrodite, and I have picked a few things up. You totally have a crush Cas." He fidgeted and went from pink to bright red. "And if I'm right? I think she likes you." He looked surprised.

"Really?"

"Bro, I'm her best friend. She has a crush on you."

"You're not kidding?"

"No, genius. I'm not kidding. You should ask her out." He went purple.

"No way!"

"You should." I could tell he was about to get up and start ignoring me, so I said in a rush- "She likes art and swordfighting and if you ask her out which you should you should take her to the fireworks on the fourth of July and-" He stood up.

"Okay, thats enough."

"Remember! Fireworks!" I hissed as he sat down next to Percy in the front. Percy started talking to him quietly, and I could tell that Percy was asking what he seemed so flustered about. I tiptoed forward to hear what they were saying.

"You don't think its a terrible idea?" Biron asked.

"No, its great. And I'm her brother, so thats really saying something. She likes fireworks."

"Thats what El said."

"Its true." I had to stifle my giggles at the fact that Biron and Percy were having girl talk. It was pretty funny. I turned and sat down in the breakfast nook, setting my head on the table. I drifted to sleep.
