Dean was seriously starting to question his life choices when his back met with the ground, Percy's sword pointing at his throat. He groaned as Percy laughed, thankfully removing the blade away from him. "You okay, old man?"

Dean slowly pulled himself up to his feet, picking up his sword with reluctance. "Shut up, Nemo," he growled as he stretched out his back.

He heard Sam walk in. "Okay, so remind me how times Percy has beaten your ass today?" His little brother chuckled.

Dean made a face and flipped him off, making Sam and Percy laugh even more. "Best two out of three?" Dean proposed. Percy shrugged his shoulders.

"Sure. I'll even go easy on you," he added, smiling innocently. Dean just gave him a deadpanned look, settling into a battle stance.

Then he got an idea.

"No swords," he challenged, tossing his sword aside before raising his fists. "Just hand-to-hand combat."

Percy casted a glance to Sam, who shrugged his shoulders in response. Percy looked between his sword and Dean's raised fists and back again. He nodded and capped his sword and placed it in his pocket. "Sure, hand-to-hand. Why not?"

Percy mirrored Dean's stance and nodded to Sam. "Call it."

Sam counted down. "Three..."

"Scared, Jackson?" Dean smirked as he and Percy circled each other.

"You wish," Percy called back, a teasing light shining in his eyes.

"Two..."

"You're going down, Nemo," Dean playfully threatened.

"One..."

"In your dreams, Losechester," Percy replied, then cringed at what he said. "Sorry, bad pun."

"Fight!"

Dean threw the first punch at Percy's jaw. The demigod dodged the throw and backed up a few steps, a slight bounce to his feet. Dean followed.

Percy threw an uppercut, but Dean blocked it. The two exchanged punches and kicks for a couple of minutes, but neither were getting a good hit in.

A few punches later, Dean feinted to the left, which Percy fell for, making him an open target for the older hunter. He kicked him in the side and Percy promptly crumpled to the ground.

Dean stood above him for a second. "Who's the old man, now?" He grinned, turning towards Sam.

His little brother shook his head. "Why do I have you as an older brother?" Dean heard his younger sibling mutter.

Dean rolled his eyes. "Because that's life, bitch."

Sam scoffed, which made Dean smile.

He turned back to Percy, who was still hasn't gotten up yet. "Percy?" Dean moved closer to the demigod. "You alright?"

Percy didn't answer.

"Shit," Dean cursed, kneeling next to Percy. He gently placed a hand on Percy's back. "Percy?"

 The next thing Dean knew was that he was on ground and Percy was on top of him, a smug smile on his smug little face.

"Pinned ya," the kid joked. The little bitch had the nerve to smirk at him!

"Get off," Dean grumbled, shoving Percy off him. Percy laughed as he landed next to him.

"Best three out of five?" Percy innocently asked.

Dean just glared at him in reply.

The kid shrugged, still grinning. "Your call, man." He got up and turned to Sam. "How about you, Sam? Wanna fight me?"

"No thanks, I'm good," the younger Winchester declined. "Maybe later. In the meantime, your friends are here."

Sam held up his tablet. Dean and Percy made their way over to Sam, looking over his shoulder. Dean could see the demigods standing outside their door, but there was one other kid there with them that Dean was not familiar with.

The kid looked around Percy's age, with messy white hair and a blue jacket with eloquent designs covering it. And for some reason, the white-haired boy had a stick slung across his shoulders and was he...

"Why doesn't that kid have any shoes on?" Dean pointed to the boy.

Percy smiled. "Long story. But when did you guys add security cameras? I didn't see any when we first got here." He looked expectantly at Sam.

Sam shrugged. "I put them up when Dean and I got back after the, uh, the black smoke attack."

Sam seemed to tense up when he said that, making Dean's brotherly senses tingle. Something was up with Sam ever since they reunited after Sam had taken care of the hospital and Dean with Jenna. He knew something must have happened at the hospital, but Sam refused to tell him what.

The only reason why Dean hadn't questioned Sam about it was because of the whole Percy scenario, fighting Greek myths and trying to find out what primordia's do for a living.

But whenever he does ask, Sam just brushes him off, saying that he got lucky at finding the cure. Which sounds normal for an ordinary Winchester. Except, Sam's not your ordinary Winchester and he's not exactly a lucky person.

There was something bothering Sam, Dean's going to make sure his little brother is alright. They've been through too much crap to not know when there's something going on with the other.

But, as of right now, that's going to have to be pushed aside. They have visitors waiting.

"Well." Dean clapped his hands together. "Let's go meet your godly friends."

***********

"Whoa!" Leo exclaimed upon entering the bunker. "This place is so-"

"Huge?" Hazel suggested.

"Spacious." The Latino elf shook his head. "I could fit at least ten Bunker 9's in here! I wonder where the inventor of this place-"

"Leo?" Frank interrupted.

"Yes?"

"Shut up."

Dean covered up his grin with a cough before looking over at Sam. His brother seemed to be engaged in a conversation with Leo while everyone else greeted Percy with a hug.

The only one who had yet to greet him was Annabeth. She stood apart from the group, arms crossed over her chest, a strange expression on her face that Dean couldn't read. Happiness? Anger? Worried? Possibly all three?

Dean made his way over to the blonde demigod. "Everything okay?"

Annabeth gave him a sideways glance before returning her attention to her boyfriend. "Fine. Just thinking."

"What are you thinking about?" Dean leaned against the wall, crossing his arms as well.

"How I'm going to kill Percy again," Annabeth simply stated as Jason embraced Percy, then proceeded to punch him in the arm as they pulled away.

"What happened the first time?" Dean furrowed his eyebrows.

Annabeth sighed. "The first time, Percy had returned to Camp Half-Blood two weeks after he exploded Mount St. Helens. I didn't really do anything then, expect punch him in the arm."

Dean nodded, remembering how Percy told him and Sam about his quest into the Labyrinth.

"The second time," Annabeth continued. "Hera had swapped the two camp leaders from Camp Half-Blood and Camp Jupiter, a Roman camp for, well, Romans. So we got Jason and-"

"The Romans got Percy in return," Dean finished.

Annabeth nodded. "Percy was missing for eight months before we finally found him." She cracked a small smile. "I judo-flipped Percy when we reunited."

Dean chuckled in return. "Well, I'm sure you'll figure something out."

Just then, Percy looked over to where Annabeth and Dean were watching. The demigod walked over to them before stopping in front of Annabeth, neither one of them saying anything for a moment.

Then Annabeth flung her arms around Percy's shoulders and kissed him.

Dean looked at them approvingly, moving away, before Sam elbowed him in the ribs.

"Dude," he whispered.

Dean hissed in pain and turned to glare mockingly at his younger brother when suddenly there was a loud thud.

Dean turned back around to find Annabeth on top of Percy, her arm across his throat.

"What'd you do this time?" Dean called out. He couldn't help it. He had missed her doing her thing and he wanted to know what happened.

Annabeth narrowed her eyes slightly, as if she were sending a telepathic warning to Percy before getting to her feet and helping her boyfriend.

"Just giving him another warning." Was all the scary blonde demigod replied, shooting Percy a look. Percy smiled sheepishly at her before leaning towards her and planting a kiss on her forehead.

"Looks like the gang's all here," Leo excitedly stated. "But seriously, though. Keep that in the bedroom." He aimed that sentence at Percy and Annabeth, who sent him a death glare. Leo gulped and jumped behind Piper, who just rolled her eyes.

"Did you guys find anything new?" Jason asked, getting down to business.

Percy shook his head. "No. We're still trying to figure it out." He walked over to the library and sat down in a chair, everyone else following his lead. "All we know is that Tartarus is planning something and he might be getting some help other than Michael and Lucifer."

"I told you guys!" Annabeth exclaimed. "I knew  there had to be someone else helping Tartarus."

"Okay, time out for a second," The white-haired boy, who introduced himself as Jack Frost (yes, the Jack Frost. Don't worry, the news startled Sam and Dean as well. Oh wait, you knew that already. Carry on.), commented. "Who are Michael and Lucifer?"

"They're archangels," Sam answered. "They've been in Lucifer's Cage for about six years now."

"Weren't you paying attention when we talked about this?" Annabeth asked, her brows furrowed at the winter spirit.

Jack sheepishly shook his head. "I was...thinking about something that someone had said to me earlier before I found you guys."

Dean knew that Jack wasn't telling the truth, as did Annabeth because she studied him with that I know you know that I know you aren't telling the truth  look. But she didn't push him any further.

"But why does Tartarus need two archangels and Pitch Black?" Jack changed the subject, getting everyone to not pay attention sorely on him. "Unless, he's planning on trying to terrify people, then what's the point?"

"Whoa, wait. Back up," Dean said, something in that sentence bothered him. "Who the hell is Pitch Black?"

"Pitch Black is Jack's enemy," Hazel supplied. "Well, the Guardians' enemy."

"Who are the Guardians?" Sam asked, scrunching his eyebrows in confusion.

"The Guardians are protectors," Jack stated proudly, but Dean noticed there was an odd look in his eyes. "We protect the children of the world."

"No offense," Dean replied, coldness hinted in his voice. "But what are you doing here if your job is to help keep kids safe?"

Jack hesitated for a split second before answering. "I'm here to help find Percy," he slowly said, almost like he was choosing his words carefully. "He and the others helped us in fighting Pitch when he was killed." Jack shifted uncomfortably in seat, as everyone stared at him. "He's also one of my friends and I figured I owed him," he mumbled as an afterthought.

"Dean wasn't trying to make you upset," Sam tried to apologize, shooting Dean a glare. "We just...we've never encountered someone like you."

Jack nodded in silence.

"You don't owe me anything," Percy protested to his friend. "It was my choice."

"But it's still my fault that you died," Jack replied bitterly.

And with that, the white-haired boy stood up and flew out of sight.
