A/N: Hooray! We have reached 100 reviews! In celebration, I will give you guys this chapter. I will never update this fast unless this story reaches 200 reviews in three days, which I do not think will happen. See? This is what happens when you review. I decide to post this early, that's what happens.

Perseus: Master of the Elements

ECHIDNA'S FALL

Before Piper had a chance to respond, Percy continued. "You know I have a girlfriend, right?"

"Yeah." Needless to say, he had a cheating girlfriend. But Percy didn't know that.

Percy looked at Piper for a while. "Just don't do that again." Piper nodded, not daring to meet the sea green eyes.

"Why'd you do it?"

Piper shrugged and didn't answer.

- Ω -

PERCY and PIPER got washed. Percy's arm was feeling a little bit better, when Hazel poured nectar all over it the wound closed up. Piper didn't have a single cut on her body, and she strapped on her armor without any difficulty.

"They're going to do it today, Percy," Piper told him.

"What are they going to do?" Percy asked.

"They're going to attack the Bunker," Piper answered, and they both stepped out of their tent (which they shared).

Jason Grace stood over a very detailed map of the Fields of Mars, giving directions to soldiers. Jason turned around when he heard Percy and Piper approach and smiled widely at them. "Hey, I see that you guys finally woke up." Slyly he whispered to Percy, "And I see that you are both sharing a tent."

Percy gave Jason his wolf stare and Jason smiled uneasily. Piper flushed red with embarrassment. Percy looked at the map. "So, what's the battle plan? Attack the gates?" Percy asked.

"Yes," Jason said. "We are planning on attacking the South, East, and West gates with Reyna at the same time."

"That's risky," Percy observed. "Then, the monsters would only have to defend three chokepoints. It'll be a bad situation for us."

"Well then," Jason countered. "I don't suppose you have any good ideas, eh?"

Percy laughed heartily. "Aren't the walls made of strong mud?"

"Yes," Jason confirmed. "Surprisingly strong mud."

"Well then, what happens when dry mud, regardless of how dry it is, get wet?" Percy asked.

"It gets all soggy and disgusting," Jason answered. "What's the point of this?"

"If some one would, perhaps, shoot a giant stream of water straight into the Southern wall, would it crumble and allow the horsemen to charge straight through, killing anything that wasn't drowned or flattened by the mud?" Percy asked again.

Jason put on his thinking cap. "Well, yes, that would work." Percy's smile probably lit up the Western seaboard. Piper's heart fluttered after seeing him smile. "But the walls are twenty feet high and fifty feet wide. No demigod has that much power."

Percy smiled and pointed at himself. "I do!"

Jason muttered under his breath. Percy didn't hear anything, but Piper could make out the words, "Even Neptune himself would have a hard time doing it."

"Alright," Percy said. "Have your Party Ponies ready to charge. Send Frank in hawk form over to Reyna and tell her that when she sees the Southern wall collapse, have her charge all of her undead, followed by infantry, alright?"

Jason looked unsure. "It would be a good plan, but you would have to deliver your side of the bargain. Somehow you have to summon a twenty by fifty foot wave and have it run about a mile to destroy that Southern wall. Can you keep it up?"

"Yeah, of course," Percy replied.

After seeing Jason's skeptical look, he added, "I swear on my honor as a Roman."

Jason smiled grimly. "If you succeed, you will become a hero of Rome. If you don't... well, let's just say there are some things worse than death, especially for an dishonorable Roman."

"Now go send Frank to Reyna, and come back here when you are ready."

Jason nodded and left to find Frank.

When the time has come for PERCY to flood the Bunker, PIPER found him at the breakfast table, sacrificing all of his food to Neptune. Piper smiled at him and said, "Jason says it's time."

Percy nodded. He got up and followed Piper to the front lines and met Jason there, pacing back and forth. When they arrived, Jason smiled. "I thought that you were going to ditch. Now go and do your work, Perce."

Percy laughed. "Just one thing, Jason. I'm going to have to borrow a horse."

Jason laughed. "There are tons of horses."

"I've noticed," was the reply.

"Here! Bring Percy Jackson a horse!" Jason roared. A soldier got off his own horse and gave the horse to Percy. Percy mumbled thanks and got on the horse.

"What's your name?" Percy asked the horse. Jason raised his eyebrows, but then he remembered that Percy was a son of Poseidon, which let him speak to horses.

A son of Neptune… it thought. We hadn't had one of those ever since ever. My name is Twister.

Well then, Percy said to the horse. Do you mind getting a little bit wet?

Nope, the horse replied.

All right, Percy said. Bring me about one hundred yards away from the Southern gate of the Bunker, just out of arrow shot.

Twister neighed in response. The soldiers parted to give Percy space and they all wished him good luck. Twister trotted down the Fields of Mars, until they were about a hundred yards away from the bunker. Percy could see dracaenae with arrows on the top of the wall, all pointed at him, but they didn't shoot because they knew he was out of range.

Percy looked back towards the barracks and saw the Party Poinies all ready to charge. Then he looked towards New Rome and saw Reyna's banners fluttering in the wind. He looked back towards the Southern wall and closed his eyes. He pictured the Little Tiber, with its water just sloshing around and he pictured the aqueduct's water rushing towards the Bunker. Percy felt a familiar tug in his gut and he heard the gasps of all the monsters and all the demigods. Unable to resist he turned around and was shocked by what he saw. Instead of a twenty by fifty mass of water it was more like a giant tsunami with a length of a hundred feet.

Percy turned around to face the bunker, sweat sliding down his face. He thought about the thing that always helped him when he did stuff like this: Annabeth. Suddenly, at the mention of her name in his mind, a third of the water fell to the ground in a giant wet slosh. Percy panicked, and he started thinking about all other things except for Annabeth when, suddenly, he thought about Piper and how she kissed him. It only lasted a second, but still, it felt so great - even if Percy yelled at her afterwards. Regret filled his body, and the regret became anger, but he calmed himself down by thinking about the kiss and Piper.

With a mighty roar Percy pointed his right arm forward and the sky went dark when the massive water sphere started flying towards the Southern wall. Percy couldn't believe it. Annabeth didn't motivate him, Piper did. But I love Annabeth, Percy thought. His thoughts were interrupted by a humongous crash and Percy looked up. The entire Bunker was flattened out and flooded, the walls were all gone, and Percy could see the crude tents that the monsters lived in.

Percy took out Riptide and roared, "CHARGE!"

The whoops and wild cheers of Party Ponies pierced the air, and instantly dozens of centaurs wielding paint-ball guns mixed with celestial bronze went ballistic, splattering monsters by the dozens. A cyclops was about to crush a centaur when a crack underneath it opened up and the monster fell into the crevice. Out of the pit came the undead warriors, courtesy of Hazel, clothed in old Roman armor. The skeletons fought every monster in sight, and soon enough the fortress became a rumble pit, with skeletons and monsters tumbling around in the wet mud. The centaurs moved to the sides, allowing the Roman demigods to come storming in. Immediately, the battle was turned in the favor of the Romans, and Percy didn't even lift his sword.

That is, until he saw Echidna.

Echidna hissed and swatted a demigod away with her giant tail. She was no longer in dracaenae mode, now she was a full snake that oozed acidic blood and she was headed for one person: Percy Jackson.

Echidna hissed and opened her mouth. Flames rushed out of her mouth, but Percy wasn't afraid. He summoned his water shield and all the fire collided with the water, turning it into steam. Echidna hissed again and slithered away, but demigods surrounded her. Echidna roared and shot flames into the air, but Percy's water shield shielded them all from the fire.

"Leave the battlefield," Echidna hissed, "puny demigods. My fight is with Perseus Jackson alone."

Percy waved off the other demigods, but they still formed a loose circle around Echidna. She hissed again, spitting acidic blood onto the ground. Percy examined Echidna and found that she had numerous arrows sticking out of her, there was even a halberd sticking out of her torso. "All I want is one thing," Echidna hissed, but this time it wasn't so threatening. It sounded as if she had given up.

"What is it?" Percy asked, genuine curiosity welling up inside of him.

"Last words and a quick death," Echidna replied. Surprised, Percy still didn't lower his sword because he was suspecting a trap.

"Alright, speak your last words," Percy demanded. Echidna hissed, and more acidic blood spat out of her mouth.

"You have defeated me, Perseus Jackson, so I want you to slay me," Echidna hissed. Percy was even more surprised.

Percy remained silent. He walked up to Echidna warily and raised Riptide. Echidna closed her eyes and waited for Percy to administrate the finishing blow, but Percy lowered his sword. "What are your last words, Echidna?"

If a giant, twenty-foot snake could grin, then Echidna would've grinned. "Soon, your whole world will crumble. There will be people you cannot defeat and enemies in the least likely of places. Heed my words, Perseus Jackson, for your life is just going to get harder."

In a rage, Percy brought down Riptide with such power that it lopped of Echidna's head cleanly. Monster dust exploded everywhere, and by the time that it was gone, Percy was trembling. Piper walked up to him and gave him a hug. "It's over!" Piper said excitedly. "We can go back to Camp Half-blood!"

"Not so fast," a girl's voice interrupted Piper's happy streak. It seems that Piper's happy streak always gets ended. "Why leave so fast, Hero of Rome?"

Reyna emerged from the crowd in her purple Praetor's toga. Piper instinctively shrunk behind Percy and her hand found his. Percy reassuringly squeezed Piper's hand. Jason also emerged from the crowd and he stood next to Reyna. "After all," Reyna continued. "Your ship seems to be in disrepair."

Jake Mason shouted somewhere, "She's right, Perce! We ought to stay here for while."

Jason and Reyna looked at him expectantly. "Percy, you are a hero of Rome. Even if you want to leave, they won't let you. The least you can do is to stay here for at least until the ship is fixed."

Percy nodded. Jason smiled and said, "Alright Frank, do what you have to do."

Frank and Dakota laughed and hoisted Percy onto their shoulders despite Percy's requests to put him down. Frank, using his loud voice shouted, "Percy Jackson, Son of Neptune, Savior of Olympus, and the Hero of Rome!"

The soldiers around them raised their helmets and cheered loudly, chanting, "Percy! Percy! Percy!"

PERCY sighed. It was the night of the day that Percy slayed Echidna, and he was exhausted. He had already eaten dinner and apparently it was going to take a month to repair the Argo II. Percy sighed and headed towards the bath area. When he reached the baths Percy realized it was crowded and was immediately disgusted until he noticed that everyone was wearing swim trunks and bikinis.

Percy was glad that he was wearing his swim trunks. He didn't want to be the only nude person in the entire bathroom, and plus, it was just wrong. He slipped off the towel and heard some daughters of Venus giggle as they looked at his half-naked body. Percy blushed red and he quickly got into one of the smaller two people tubs and relaxed, letting the hot water do its job. Instead of turning on the jets, Percy made the water rise up and massage his temples and arms. This feels amazing, Percy thought. Now if only the bathroom wasn't so crowded and noisy…

Suddenly the jets turned on and bubbles flew everywhere. Percy looked up and saw Piper relaxing in the same bathtub as he was in. Percy started panicking and was about to get out the bathtub when Piper let out a soft moan of pleasure. Percy immediately got back in the tub because he felt something go wrong in his Scandinavian regions, and if he got out of the tub now he would probably die of embarrassment.

Percy decided to relax. It doesn't matter that Piper is in the bathtub with me; I mean, after all, she is wearing a bikini and I am wearing swim trunks. Right? Percy asked himself. Percy closed his eyes and maintained his composure until Piper accidentally brushed her leg against his. Percy immediately went rigid and curled up into a ball.

Piper opened her eyes and flushed a deep red that made her (In Percy's opinion) look incredibly cute. "So, uh, Percy… how's… the bathtub?"

"Well," Percy said. He thought of something to say without sounding weird. "It uh, just got hot?"

Piper flushed a deeper red, if that was possible. "Oh gods no," Percy quickly corrected himself. "No, I didn't mean it that way, oh Hades no… whatever just forget what I said, ok?"

Piper nodded, still flushing a deep red. Percy tried to keep the conversation alive. "So uh, what are you wearing?"

Piper looked at Percy with a quizzical expression. Percy realized his mistake and tried to keep a calm demeanor, but it was obvious that he was panicking. "Uh, forget that, uh…"

Piper laughed timidly. "Now I think I know by what Annabeth means when she calls you dense."

At the mention of Annabeth, Percy seemed to become a little bit more sober. Percy started rising out of the bathtub. "I think I'll go to bed now."

"Yeah, alright remember your bed is the bottom bed, I get the top one," Piper replied nonchalantly. Percy paled. She's joking, isn't she? No way in hell would Jason make me share a room with Piper. For some odd reason Percy liked the idea of sharing a room with Piper, but he quickly pushed that thought out of his mind.

He quickly wrapped a towel around himself and muttered goodbye to Piper and sprint-walked out of the bathroom. When he was at the room Jason told him he was going to sleep in, he took a deep breath and opened the door with the key. And he gasped.

It turned out that he did end up sleeping on the bottom bunk.
