Took me a little while to decide what to do next, but here's the next chapter!

A little way into the tunnel, there was barely any light left to illuminate the way, even with Leo's blazing hand. Odd formations of rocks decorated the walls and ceiling of the cave, though the floor was smooth, and the path was straight, a clear sign that it was not naturally made.

The path seemed to go on forever, which gave Jason plenty of time to think about the potion in Hazel's dream. Then he realized something that almost made him stop. The sons of the Big Three...Both of the sons of the Big Three were currently together in this dark tunnel. What if it was a trap? Jason didn't think that the giants would be reckless enough to accidently allow one of them to learn about the crystal.

Then Jason's thoughts turned to his companions. Leo had been kind of withdrawn and closed ever since Khione had blown him off the ship, like he was heartbroken or something. Obviously, he had met a girl he liked (which didn't help much, since Leo liked a lot of girls), and either the girl hadn't liked him back or he had had to leave her behind to return to the Argo II. Leo had refused to discuss what had happened, and all Jason knew was that Leo had gotten a magical fireproof pouch for Frank.

Percy, on the other hand, was a lot more serious and quiet. Despite that, he and Jason had been getting along quite well, at least better than when they had first met. Jason thought that Percy was a good leader and was well admired by the rest of the crew.

Eventually, Jason saw a faint blue glow at the far end of the tunnel. "What do you think that light is?

Percy squinted. "Looks like...water."

When they reached the blue glow, now more of a glittering turquoise shine, Jason saw a large room with a fountain was elaborately carved. There was a tunnel on the other side of the room, and Jason hoped nothing dangerous came out of it.

Percy shuddered. "That figurine at the top of the fountain looks like the statue on the head of the boat Princess Andromeda. Not exactly the most reassuring sight."

"The what boat?" Leo asked.

"Never mind. It was before you arrived at Camp Half-Blood, during the Second Titan War."

Jason walked over to the side of the fountain and looked in. The water did seem to be the source of the glow, and there were a pile of coins at the bottom, so Jason assumed it had once been a wishing fountain.

"Look. There's the jewel we were looking for." Percy and Leo were now by Jason's side. A large multicolored crystal was at the bottom of the pile of coins. As Jason reached in to grab it, Percy stopped him.

"You don't feel it?" Percy asked. Jason raised an eyebrow.

"Feel what?" he asked.

"You know...That sense of evil lurking in the water?" Percy tried to explain. Leo shook his head.

"Bro, I have no idea what you're talking about. Let's just grab the crystal and go. I don't know about the water, but this place gives me the creeps."

"Well, then you should let me do it. I might be able to figure out why the water is like that," Percy said.

"Go ahead," Jason said, glancing warily around. He agreed with Leo. The place just didn't feel...right. "We should get back as soon as possible."

Percy hesitantly reached a hand into the water. Jason saw his fingers closed around the jewel, and immediately, Jason saw that something was wrong.

The crystal began to glow with a soft light, but the water darkened and started to swirl. Percy quickly pulled his hand out. But the crystal seemed to have absorbed some of the water and was now glowing a much darker color. In fact, the crystal was now a dark greenish-black.

"What's going on?" Jason leaped back from the fountain. Percy tried to put the crystal in his pocket, but to his dismay, the crystal seemed stuck to his hand.

"Uh, a little help here?" Percy asked. Leo ran over and began to pull at the jewel.

"Geez, that's stuck pretty tight. I can't seem to budge it." Leo grunted.

Jason looked up at the tunnel on the other side of the room. "Um, guys, I think we've got a bigger problem," Jason said, taking a step back. The large, shadowed outline of a giant filled the mouth of the the other tunnel.

With one last tug, Leo pulled off the crystal, and it flew across the room, directly into the giant's waiting palm.

"Hmm...It seems that it has chosen." The giant examined the crystal and then pocketed it. Jason winced as the giant spoke. His voice was deep and caused a prick of pain with every word.

"Hey! What do you think you're doing! That's ours!" Leo stepped forward defiantly.

"Is that so?" the giant raised an eyebrow, amused. Percy drew Riptide and stepped forward as well.

"Yeah, that is, Meat-Face. I don't know why you're here, but we claimed that first," Percy said.

"Well then. I hate to disappoint you, but that crystal was in my possession long before I put it into the fountain." The giant chuckled.

"You placed it there? You sent that dream to Percy on purpose? This was all just a trap to lure us into this cave?" Jason asked furiously. He wasn't sure if he was mad at the giant or at himself for letting them fall into the trap so easily.

"Well, not all of you. Not that scrawny little runt of a demigod over there." Leo uttered a sound of protest. "I only needed one. But no matter."

"Whoa, stop right there. Did you just call me a scrawny little runt? You're going to have to pay for that," Leo said angrily. "You are so dead." Percy put a hand on Leo's arm.

"Let us deal with him. You don't have a weapon right now."

"Yeah, a screwdriver won't do the trick," Jason drew his sword as well. The two of them faced the giant.

"Which giant is he? I don't recognize him," Jason whispered to Percy.

"I don't either," Percy chewed his lip thoughtfully. "If only Annabeth was here."

"Hmm, two demigods? Is that all? I guess I'll have to inform you that you'll need the help of a god to defeat me, and the gods are a little...indisposed right now," said the giant leisurely.

Jason ground his teeth in frustration. The giant was right. How would they defeat him? Suddenly, Jason started feeling a little nauseous and sick.

But before Jason could do anything, the giant yawned. "Well, enough talk. You're starting to bore me. It's time I got what I came for."

The giant advanced, but Jason stood his ground, sword pointed out in front of him. "And what exactly did you come for?"

"Well, you'll find out soon enough, won't you?" The giant opened his robe and took out a small vial. He took off the cork stoppering the vial, and immediately, the thick gray smoke inside the tube swirled out towards the demigods.

"That doesn't look like it would really help our health, so we're just going to go now," Leo said nervously heading back towards the tunnel. "Come on, you guys."

Jason backed away from the mist, but it just kept on coming. Percy was still standing there. "Percy? Are you coming?"

"We won't make it in time." Percy sounded completely sure of that. "You guys go back and alert the others. I'll um…fight the mist?"

"I see we have the right choice," the giant said, picking out dirt underneath his fingernails. "It's only a matter of time."

Jason didn't have time to ponder the giant's words. The fog was rolling closer. "Come on, Percy. We can't leave you behind. What would Annabeth say?" Jason pleaded. Percy hesitated. But it was too late. Much too late.

Jason stared in horror as he saw the smoke envelope Percy. Who knew what it would do? "PERCY!" he yelled.

"Come on, we have to leave, otherwise the mist will reach us too. I don't want to leave him behind either, but some of us have to alert the others." Leo tugged on Jason's shirt. But as it turned out, they didn't need to leave. The mist cleared, and Jason saw that the room was now empty. No fountain. No giant. No Percy. Only Percy's sword was left on the ground.

"Where did he go? Where did Percy go? Annabeth's going to kill me," Jason muttered. He ran into the room and picked up Riptide. "Percy? Percy!"

"Maybe down the other tunnel?" Leo suggested. But as Jason turned towards it, a large rock slid down in front of the opening, unseen before because it had looked like a normal rock outcropping.

Jason stood there in dismay. What were they going to do? Percy had disappeared, and they couldn't just leave him behind like that.

Jason became dimly aware that Leo was shaking him. "We have to leave. It's our only option, and our only hope of finding Percy."

Leo headed towards the tunnel the had entered through, and with no choice left, Jason followed, taking one last glance at the cave where Percy had disappeared.

Oh no! *gasp* What will happen to Percy?

I need some ideas for the next chapter so please suggest some!
