Dean walked into the building and found himself in the back staircase of a really old, grimy building with peeling paint and a distinct smell of damp mold growing somewhere.

He pulled out his silver blade and held it in front of himself, in case Annabeth jumped him. With the blade in his hand, he took a second of consideration.

Up or down?

He decided on down and started following the square shaped stairs. It was cold and he could see his breath.

Other than his feet against the hard, stone steps and his soft breath, there was no sound in the seemingly abandoned building. But Dean knew better. If he closed his eyes he could almost sense the presence of another body down a few more flights of stairs.

The yellowish light flickered once but Dean didn't think much of it. This wasn't a demon case, it was just a shifter.

He finally reached the bottom of the stairs and he stood for a minute. There was piles of boxes covered in sheets, and pipes sticking from the walls. It felt damp and gross and a good place for a shifter.

"What are you?" A sharp voice asked suddenly from somewhere off to the side.

Dean whirled around, but he didn't see anything.

"Excuse me?" He asked.

"What are you?" The voice came again. It was definitely Annabeth's voice.

"Annabeth?" He asked.

There was a moment of hesitation and Dean grinned.

"Yes. But you didn't answer my question. What are you and why were you following me? You're no FBI agent and you didn't have me fooled for a second… your brother either."

"How'd you know we're brothers?" Dean asked carefully. The situation suddenly wasn't funny anymore.

"Oh, please. I'm not blind. It's written all over both of your faces, plain as day. Even Percy could see it. That's why I'm here, you know, because Percy called me the second you guys left his house."

Dean began walking around, looking behind boxes and other covered things, looking for Annabeth.

"So you want to know what I am?" He asked.

"I'm dying to know."

He spread his arms out wide as if to say, 'here I am!' and continued circling, trying to find where the son of a bitch was hiding.

"I'm a hunter." He said proudly.

"A hunter?" Annabeth asked doubtfully. "So you're just a mortal? Why are you following me, then?"

"A mortal? What, is that some kind of insult?" Dean shook his head. "I was following you because you need to be hunted, you son of a bitch."

"Me?!" The shock in her voice was evident.

Silence fell between them again as Dean allowed Annabeth think this over.

"How much do you know?" She asked carefully. He voice didn't waver and Dean couldn't even detect any fear in her voice.

"That depends…." Dean returned. He was getting frustrated. It sounded like she was standing right behind him but he couldn't find her. "I know you and your boyfriend have been racking up the body count lately, you could have done it quieter... I know how to kill you, how to make you suffer." He stomach clenched up as he realized he would gladly torture this monster before letting her die, for no reason. He held up his blade. "It's silver. That stuff burns, don't it?" He grinned cruelly but he could feel the familiar hate he held for himself burning in his stomach.

"Why would silver be different from any other blade?" Annabeth asked. Now she sounded confused.

"Well, uh, you're a monster… and, uh, silver hurts you?" Dean almost asked. Now he felt all muddled, she was tripping him up. Other blades would hurt her?

"I guess silver would hurt, but it would be like any other knife…"

"What are you?" Dean asked now.

All of the sudden, the door from upstairs burst open and Dean could hear feet thundering down the steps.

The person who was coming down obviously didn't care about the element of surprise.

Percy appeared at the bottom of the steps and he pointed a gun at Dean. The image of the gun shuddered and Dean had to blink a few times before he could focus on it again.

Dean held up his hands, quickly trying to come up with a plan. Where was Sam?

"Annabeth?" Percy called out, his eyes never leaving Dean's face.

"I'm here, Percy."

"Put the knife down." Percy ordered. His voice was sharp and clear, it was apparent Percy was used to giving orders.

"Percy," Annabeth voice was urgent. "He's a mortal. He's not a monster."

This news surprised Percy. He blinked and then lowered his gun half an inch. "Oh… So what do we do now?"

"Run?" Annabeth suggested.

"I don't think so." Sam said.

Without anyone noticing, he had come in from the door and snuck down the steps. He was now standing with his silver blade raised behind Percy's back.

"Sammy! No!" Dean yelled.

Sam stopped just as he was about to plunge the blade into Percy. He looked up as Percy backed away.

"They're not shifters." Dean said.

"Shifters?" Percy asked. "What's a shifter?"

"What? What are you?" Sam ignored Percy's question. "Are you a demon? A ghoul?"

Percy's eyes searched the room carefully before he said anything, weighing his options. This was obviously an important question and getting it wrong obviously meant fighting to the death.

"Annabeth? Could you come out for a sec?" He asked.

Right beside Dean, holding a knife near his throat, Annabeth appeared, holding a Rasta cap in her free hand.

She didn't say anything but the look she gave him meant 'I could have killed you.'

Her steps echoed against the damp floor as she took her place beside Percy. They held whispered counsel for a few seconds as Sam and Dean exchanged confused glances.

When they stopped whispering, they looked up and glared steadily.

"I don't know how much you know," Percy began. "But obviously, you know something about something weird…"

"Trust me, man, weird is our life." Dean said, quoting Percy from earlier. But he relaxed, for the moment, content to talk.

Percy chewed on his lip, and he looked at Annabeth again for support. She gestured at him as if to say 'go on!'

"Are you guys… Greek?" Sam asked. His eyes wide and his body tensed up again. That why they had felt familiar before. They were demigods.

"How'd you know?" Percy asked. He took a step back and pulled his gun up again.

Sam blinked and tried to steady his breathing. "We saw Annabeth do something earlier that the superstitious Greeks used to do." He explained. "And your necklaces… they have some… Greek… things on them, I guess."

For the first time, Dean noticed the leather necklaces both the teens were wearing. They had beads on them that were decorated with bright paint. The necklaces looked like something one would make at a summer camp.

"Sure, we have…" Sam said. "We've dealt with stuff like that before."

"So you already know that they're real?" Percy asked.

Sam nodded his head.

"Yeah, finding out they're real wasn't a shock… it was finding out how big of dicks they are that was the big surprise." Dean said, kind of bitterly.

Percy laughed nervously. "Great, so you already know the basics." He smiled apologetically. "How about I introduce myself again?" He held out his hand to Dean. "Hi, my name is Percy Jackson, son of Poseidon, god of the seas."

Dean looked at Percy's hand, then up at Percy, then to Sam.

"If you don't shake my hand, this will get awkward." Percy stage whispered.

Dean slowly took his hand and shook.

"Annabeth Chase, daughter of Athena, goddess of battle strategy and wisdom." She held out her hand to Dean as Percy went to shake Sam's hand. "And, the official Architect of Olympus."

She smiled proudly.

"Right." Dean drawled.

With a glance at Sam, they both pulled out their guns from their belts and pointed them at the teens.

"Alright, demigods, we're still hunting you."

"Whoa! Whoa! Whoa!" Percy jumped back, holding up his hands in surrender, even though he was still holding a massive gun. "Dude, I thought we were friends."

Annabeth rolled her eyes and lowered one hand to punch Percy in the arm.

"We're kids!" She said, turning on Sam, like she knew he would have more sympathy. "Are you really going to murder us?"

"It's no murder, we're hunting." Dean said.

"Plus, for all we know, you could be hundreds of years old." Sam added.

"You know they're not hundreds of years old…" Lucifer whispered in his ear. "You just want to gank 'em for the thrill of it."

Percy rolled his eyes. "Dude, I'm seventeen."

Sam pointed his gun at Annabeth. "Me too!" She frowned at the nose of the gun. "You seemed to think we were responsible for the girls that have been going missing…" She put her hands behind her back and started pacing back and forth, like she knew they weren't going to shoot. "To make this work without one of us getting killed, we need to know what you know and how you know it."

Sam lowered his gun and quickly pressed into his hand. The pain shot up through his arm and seemed to flick a switch in his brain that that turned Satan off.

"We were brought up in The Life." He started, trying not to let anyone notice how distracted he was.

"Sammy…" Dean moaned.

Sam continued. "We hunters. That's what we do, we travel all across the country looking for monsters, spirits, ghouls, ghosts, demons… stuff like that. It only makes sense that we would run into some Greek stuff, too."

Percy looked really interested. "You hunt monsters for a living?"

"Not really." Dean said. "We don't get paid… It's more like, we pay them with blood, sweat and tears and we get dead friends and bitter lives in return."

"Oh…" Percy looked down.

"That's about it…" Dean continued with a pointed look at Sam. Don't mention angels. He silently begged him.

"Well, now it's our turn." Annabeth said. She went into her teacher mode. "The Greeks gods, or the Olympians, are the source of the Western civilization… Where the point is strongest, that's where the Olympians go."

"So the Greek gods are in New York?" Sam asked. "Where?"

"Top of the Empire State Building." She hesitated. "Don't bother looking, it's covered by the Mist."

"What mist?" Dean asked.

"The Mist, with a capital 'M', is this force, no one really knows how it works, but it prevents mortals like yourselves, from seeing what's really out there. You probably think that Percy's holding a baseball bat, or a gun or something." She pointed to Percy.

Percy held up his weapon and snapped his fingers loudly. The sharp sound echoed off the walls and bounced around, ringing in Dean's ears. Nothing extraordinary happened except that the gun he had been holding turned into a long, bright, bronze sword from Ancient Grease.

"We're demigods, half-bloods, heroes, mistakes, we've heard all the names." Percy picked up from Annabeth. "When we're born, we look normal, we act normal, we are normal, until our sent gets stronger."

"I'm sure some deodorant would fix that." Dean joked in a strangled voice.

"Our sent attracts monsters." Percy ignored Dean's attempt at humor. "So we're trained to fight, to live… go be the god's playthings when they get bored…" Percy shrugged. "It's a hard life but it's ours. And we're not immortal, like you seem to think. Honestly, I'm surprised I made it to seventeen."

"Sorry, this is a lot of information." Sam scratched at his head. "Um, so you don't know what's happening to all the missing girls?"

"Nope, at least, we don't right now." Annabeth said. "We went and talked to Nancy after we talked to you guys in the Pizza parlor… She really did see a hellhound, I think."

"Which means Hades is behind it." Percy filled in. "Or something else that has control over those monsters."

"Hades? You mean, like, the actual god of the underworld?" Sam asked excitedly.

"Nerd." Dean coughed into his hand.

"That's the one." Annabeth said brightly. "Quick way to do this would be to IM Nico, see if he knows what the hell is going on in his dad's mind."

"I don't want to talk to Nico." Percy complained. "He hates me…"

"Who's Nico?" Dean asked.

"Nico Di'angleo. The one and only son of Hades." Percy said. "We had a few problems a couple years back, I'm not sure we've sorted them all out."

"Don't be such a baby about it." Annabeth said to Percy, rolling her eyes, as if it was just him being petty about the whole situation.

"He betrayed me and gave me over to his father!" Percy cried out. "We could have lost the whole war because of him."

"Yeah, but we didn't."

"Hold on," Sam stepped closer, holding his hands out.

"War?" Dean demanded. "What do you mean war?"

Both of the demigods averted their eyes. It was a touchy subject for both of them, Sam could tell, but he needed to know.

"We had a war last summer because Kronos, the King of the Titans, was rising." Percy raised his eyes and looked right into Sam's eyes. "He pulled a lot of crap and a lot of ours went to his side, the war happened right on the streets above us."

"It wouldn't have happened to be around the middle of August, would it?" Sam asked.

Percy looked surprised. "Yeah, why?"

"No reason." He said quickly. He shot a pointed look at Dean to say 'we'll talk about this later'.

"So, shall we give Nico a call?" Annabeth asked in the awkward silence that followed.

Dean and Sam shrugged at each other. "It looks like the only lead we got."

"Percy? Would you do the honors?"

Percy flushed bright red. "Please don't freak out." He begged Sam and Dean. "This is just something I can do, it's not evil so don't shoot me."

Then he closed his eyes and waited. The water dripping from the walls and ceiling stopped falling on the ground and all started to move together in front of Percy. They formed a little puddle on the ground and then the drops went up in a cloud of mist. Because of all the oils and whatnot in the water, it made the muddy water look like a rainbow.

"Yuck." Annabeth commented.

She pulled a large, gold coin out of her jacket pocket with strange imprints on it.

"Oh, Iris, goddess of the rainbow, please accept our offering." She threw the coin and Sam and Dean both sucked in their breath and looked at each other when it disappeared in the muddy mist.

"Show me Nico Di'Angilo in the Underworld."

The wall of misted water started swirling and moving until it formed into a picture of a young boy, sitting in a dark room with skulls and bones lying around.

Right the moment, he was throwing a small sword with a black blade at the wall. It would stick and then he would get it and throw again. Like a really dark and morbid game of darts.

"Hey, Nico." Annabeth greeted, rather grimly.

Nico looked up startled. He relaxed when he saw it was Annabeth.

"Oh, good!" He said. "I'm so glad to see you guys!" He got up from the bed where he had been laying and stood in front of the IM.

"Nico, what's wrong?" Percy asked, picking up on the panic in his voice. "Are you in trouble?"

The boy only nodded. His large, dark eyes stood out against his pale face. Dean thought he looked more like a spirit than a person, let alone a powerful demigod.

"It's my father, he's gone insane!" Nico said.

"What is he doing?" Annabeth asked.

"He's trying to be a good dad."

Percy slapped his head. "Aw, Nico…"

"No! You don't understand! He's kidnapping girls to 'be my friends' and interviewing them and-."

Percy didn't even let Nico finish his story.

He doubled over, laughing, holding his stomach. He laugh rang out and vibrated the whole room. Annabeth leaned onto him for support as she shrieked with mirth.

"Guys! It's not funny!" Nico stamped his foot in frustration. He looked freaked out and his hands clenched into small fists.

"I'm sorry, man." Dean chuckled, "But your dad really needs to learn how to talk to girls."

"Who the hell are you?" Nico demanded over Percy and Annabeth's laughter.

"I'm Sam and this is my brother Dean." Sam said, trying to keep from laughing at the ridiculousness of the whole situation.

Nico's eyes grew large. "Winchester?" He asked disbelievingly. "Sam and Dean Winchester?"

"Who's asking?" Dean asked, on guard again.

Nico scoffed. "I'm the son of death... It's a game we play down here to see when you'll come next and how long you'll stay."

This quieted Percy and Annabeth.

"What?" Annabeth wiped tears from her eyes. "You guys have been to the Underworld?"

"Are you kidding me?" Nico said. "They've both been down here more than either of you."

"That's impressive." Percy nodded approval. "Elysium or Tartarus?" He asked jokingly.

Nico looked grim. "They've been to both but even Elysium didn't seem to make them happy. Even there they were hunted." Nico wrinkled his nose. "They see the whole bible stuff. Heaven and hell? Pretty religious guys, if you ask me." He shook his head sadly. "They've both got 'death' written all over them."

"Fun stuff." Percy said drily. "Maybe you should stop dying?" He glanced over at the boys and immediately wished he hadn't said that. "So, anyways, your dad." He changed the subject because he could tell Sam and Dean were getting uncomfortable.

"I tried telling him to stop but I got locked up in here."

"Doesn't he see it's a little bit creepy?" Sam asked.

Nico shrugged. "That's how he got his wife."

"You're fifteen!" Percy said.

"He's really stuck on the 'old ways'."

Annabeth sighed. "Do you need us to come talk some sense into him?"

"Yes, please." Nico said weakly.

"We'll be there in a few more days… Stay strong, kid." Percy said.

Nico blushed. "Okay, but you two." He looked at the Winchesters again. "Right now, the darkest part of Tartarus has your names on it. I'd try not to die again, if I were you. You're running out of 'get out of jail' passes. You have one hellish place waiting for you."

Even though the kid was a scrawny fifteen year old, Sam and Dean shuddered at his words. Combined with the creepy decor and his pale, sunken in face, he looked like he had endured his own personal torment his whole life and even he wouldn't want the Winchester's in the hell that was waiting for them.

"We'll try our best." Dean said, with grim smile and a wink.

Nico nodded.

"Hurry." He said to Percy and Annabeth. Then he reached out to disconnect the IM.

"Wait!" Sam called out. "Can you… could… Is there any way…?" He struggled to find the right words.

Nico cocked his head to the side, silently watching Sam with an expressionless face.

"Do you know where the people go, when they die?" Sam asked, finally.

Nico nodded.

Sam took a deep breath. "There is a lot of people I feel responsible for…" He started to say. "Could you let me know… are they… okay?" Sam asked. He winced at his own words.

Of course they weren't okay. They were dead.

"People like Jo?" Nico asked. "And Ellen? Ash? Your parents?" He hesitated. "Jess?"

Sam pursed his lips. Each name hitting him like a punch in the gut. "Yeah, those people." He voice was horse.

"Sammy…" Dean's voice was thick too.

Percy took Annabeth's hand in his own. They both looked on sadly, each knowing what it was like to feel so desperate for the answers.

Nico was unsmiling as he shoved his bony hands into his jacket pockets. He chewed on the inside of his cheek.

"I'm not supposed to share information like that." Nico said.

"Please…." The word held so much weight, it physically pushed Nico down.

"Most of them are okay." Nico said. "They're waiting for when you come to stay, so you can all be together." His eyes sifted around, not settling on anything except the floor.

"Thank you." Sam whispered.

Dean narrowed his eyes. He wanted to believe so badly what Nico was saying that it hurt… but something was stopping him. Lips pursed, he turned his head away so Sam would see him.

Nico's hand swept put and quickly disconnected the IM.

"It's hard… having people you love die." Annabeth's morose voice broke the silence.

Sam and Dean remained still.

"I guess we're off to the Underworld… Time to go see Uncle Hades, again…" Percy made a face, trying to get them to talk.

"No offense, but it sounds like you guys should really stay out of Hades way, so maybe you should….?" Annabeth let it hang.

"Eh, don't worry about it." Sam said, coming back to earth. "You guys go on your quest… As long as the kidnappings stop, we'll be happy."

"You got it." Percy held out his hand to shake with the Winchesters, who made a show of putting away their guns.

"Here." Annabeth gave each of them one of the large coins they had seen her throw into the mist. "If you ever encounter another demigod, show them this and tell them that you're a personal friend of Percy Jackson. They won't hurt you and they'll do their best for you. But if it's a monster, tell them you never met us?" She smiled again. "It also works for the quick message that I just used, throw it into a rainbow and ask Iris nicely and she'll connect you, got it?

It looks like you guys have a long ways to go in your quest." She added. "If you're ever in New York again, I'd love to meet up, I want to know all about this 'hunting' job."

"Trust me, sweetheart," Dean shook her hand. "You don't want to know."

"It'd be a nice switch up, though. Being the hunter instead of the hunted." Percy shrugged. "You never know.
