Hello! This will be my second piece on here. I guess you could say I'm a veteran. Maybe. Not really.

I've had this idea for a long time, and I've finally gotten down to writing about it. I've actually already got the second chapter written: review and tell me when to publish it, or else I might not! No, I'm going to. Maybe. Someday.

I don't own Percy Jackson and the Olympians or any of Riordon's works, or the Supernatural series.

Percy ran through a maze of streets and alleys, but somehow his pursuers were always right behind him. Of course, it didn't help that he was carrying Annabeth's limp form. The extra weight, paired with the stitch in his side from running, slowed him down considerably. Following his instincts and ignoring his pain, the dark haired, green/blue eyed boy came upon an old stone bridge covering a decent-sized river. It was lit by a single, flickering lamp-post. Out of breath, he stopped and set Annabeth down in an upright position supported by the stone wall of the bridge. He quickly rummaged through her small backpack, finally finding a flask of amber liquid. He uncapped it and had begun to pour some into Annabeth's mouth when he was yanked back.

"Hey, kid! Just listen for a sec-"

Dean was interrupted when Percy kicked his knee and brought his elbow back into his shoulder, throwing him off balance and causing him to release him. Percy took a protective stance in front of Annabeth, shielding his friend from harm. He took out the ballpoint pen that Chiron had given him all those years ago and uncapped it, releasing Riptide's blade. Sam and Castiel stepped unconsciously away from the sharp celestial bronze, but the one who had grabbed Percy before just looked at him quizzically. "What are you going to do with a pen? Write on me?" he said.

"You can't see through the Mist? You're mortal!" Percy exclaimed in surprise. "But you two can...?" He looked to the other men, who could apparently see just how lethal Riptide really was. "Who are you?" he demanded.

"Look, let's all just calm down," the taller man said as he advanced towards Percy and Annabeth. Percy quickly reacted by sticking the point of his sword under the man's chin, and Sam put his hands in a surrendering position.

"Not one more step. I don't know who or what in Hell you are, but trust me when I say I will not hesitate to cut open your throat if you hurt my friend." It was partly a bluff; the celestial bronze would do nothing to regular humans, but hopefully they couldn't see through it.

"Okay, okay," the man said in a soothing tone. "No attacking." The sword was kept at his neck. "Why don't we introduce ourselves? My name is Sam Winchester. This is my brother Dean," he said, tilting his head in the blonde man's direction. "That over there is Cas - or, Castiel. Cas for short." The man in the trench coat studied Percy and Annabeth intently, not saying a word.

Percy waited a few moments, then said, "I'm Percy Jackson, and I'm the last half-blood you want to fight, especially above a river."

~oOoOoOo~

Sam racked through his brain, trying to figure out where he had heard that term before.

Half-blood...half-blood...what is a half-blood?

Then he remembered that case years ago. A man was using an Ancient Greek spell to revive his dead girlfriend, who was - what else - the daughter of a professor in all things Greek. Sam had quickly flipped through some of the books in the father's study, and half-bloods were mentioned in almost every myth, legend, prophecy, and poem.

"Half-blood? Like, half human, half god?" he asked, wary of the boy's sword.

"Come on, Sam, are you saying this guy's, like, Jesus or something?" Dean asked.

"He is not Jesus. Jesus has not been resurrected yet," replied Cas.

"Jesus? In my world, God doesn't exist." Cas bristled a little at this remark. "Now, gods, plural; that's a whole different matter entirely. Specifically the Greek."

"Greek gods? Seriously?" Dean chuckled.

A stormy look in his eyes, Percy raised his hand to Dean, like he was reaching for something. A second later there was a low rumbling underneath the bridge, and a wall of water rose on each side and formed a tunnel.

"Something funny?" Percy asked.

Dean was about to reply when the boy said, "What do you mean, 'Chiron said to bring them back to camp'?!"

The three other men were all confused by this outburst until they noticed a shape floating in the wall of water behind Percy. Their eyes widened as they recognized a glossy, scaled tail, strong forelegs with hooves, and a shiny mane, rippling and flowing through the moving liquid.

Percy cursed in Ancient Greek and told the hippocampus to go back to camp. "Change of plans," he said. "I need you to come with me."

~oOoOoOo~

After they decided not to kill each other, dean and Castiel sat off to the side talking, and Sam stayed with Percy while he tended to Annabeth, asking questions.

"So, uh, I'm assuming you're half human, half god, so...who's your parent?"

"My mom lives in an apartment on Upper East side and likes blue candy; Dad lives in a palace under the sea and likes hippocampi. Take a wild guess."

"Poseidon?"

"Yep. God of the sea and crazy floral prints."

"How are the gods here - in North America, I mean."

"Well, they originated in Greece. Then, Greece was taken over by Rome, and the gods changed form to be with the highest power. Then Rome was taken over by some other guys, and the gods changed again. And again, when those guys were taken over. Basically, the gods take different forms, but the follow western civilization. And that so happens to be today..."

"The United States," Sam finished.

"Right. Exactly. And I guess because America doesn't have a religion with many gods, they reverted to their roots: Greece."

"Huh. So, all the myths. Are they true, or just some of them?"

A low rumble was heard from above, like thunder, but no storm clouds were in the early morning sky. Percy looked up anxiously.

"You better believe that they are, or they'll cut you to pieces. Oh, and my uncle just threatened to 'smite you faster than you can blink'," Percy imitated in Zeus' voice.

It took a moment for Sam to process.

"Wait. That thunder, that was Ze-" He was cut off when Percy clamped a hand over his mouth.

"In my world, name have power. You say it too many times; they'll just come running at you. Believe me, my uncle isn't the most welcoming god."

Sam nodded, and Percy released his mouth. He took out a flask of amber liquid and poured some drops into Annabeth's mouth. Sam asked what it was.

"Nectar," Percy replied. "The chosen drink of the gods. For demigod consumption only. We use it to heal." He put the flask away, still three quarters full.

"Why don't you use more?"

"It's the drink of the gods. We're only half god. Too much will burn us up. Like, literally, 'burst into flames' burn up." He checked Annabeth's pulse. "Good. She's stable. Alright, we're heading out in a few minutes!" he called to Dean and Cas. He whistled like you might for a cab, and then silently watched the horizon.

"What you you-"

"Shh. Aha! They're almost here."

Five tiny dots turned into five horses with graceful wings and one rider. He was tall, bald, and had a tattoo of a rainbow on his bicep.

"Butch! My man! Thanks for getting here so fast."

They man hugged and helped Annabeth onto a black stallion, then Percy got on behind her. The others were still staring in awe at the winged equestrians.

"Come on!" Percy said with a smirk. "Haven't you ever ridden pegasi before?"

Sam eagerly climbed onto the back of a chesnut mare, grinning widely, but Dean and Cas hesitated.

"Oh, come on, Dean," Sam chided, rolling his eyes. "Don't tell me you're still afraid of flying."

"Hey; deathtrap in the sky, 20,000 leagues ABOVE the sea. It's a rational fear!" Dean replied hotly.

"I agree," Percy said.

Sam looked pointedly at his pegasus' wings.

"Oh, not on Blackjack. The skies are my uncle's domain, horses were made by my father. Pegasi are neutral territory. But I pissed off most of the gods at least once, so if I ever fly on a plane..." He mimicked an explosion with his hands. "It'll be fried by a lightning bolt."

"Your dad made horses?" Dean asked while he gingerly mounted a golden pegasi with fluffy, cream-colored wings.

"Out of seafoam!" Percy yelled back as Blackjack jumped off the bridge and flew into the early morning. Sam quickly followed. Dean looked back at Cas, who was still standing.

"You gonna come?"

"I prefer my own method of travel."

"Alright, suit yourself."

Dean's pegasi finally took a running start and lept off the bridge, his knuckles white from holding onto the reins. With an odd glance at Cas, Butch left too, leading the riderless pegasi.

Castiel watched the departing group for a moment, then swiftly turned on his heel. The one lamp post's bulb burst with a crack; there was a flash of light, and the trench coat wearing figure was nowhere to be seen.

So! The trio meets up with Percy and fly to Camp Half-Blood - what happens next? How will people react? Will Chiron allow them to stay? How will the gods feel about this? I DON'T KNOW, I'M JUST THE WRITER, STOP BOMBARDING ME WITH YOUR PETTY QUESTIONS.

Anyway...

Please review, it only takes a minute of your time. I'll most likely get back to you if you have anything you're unsure about. If you ask nicely. And address me as 'Lindsey, Ruler of the Nine Realms, Defender of Literature and All Things Good in This Godforsaken Society'. And no, I probably don't deserve that title. A girl can dream.

Sincerely,
