"Home, sweet home." Percy said as he stared at everyone in the room. His mouth twitched into an evil smirk as a scared look came over Cas's face.

"Nice to see you again little brother!" He called over. His eyes searched the room before landing on Annabeth and Chiron.

"The daughter of Athena and her teacher. How wonderful." He drawled as he pushed up off the game console and crossed his arms.

"I assume you've come here to learn more about myself Winchesters?" The demon asked, tilting his head and grinning wickedly. Cas's blue eyes narrowed at Percy, as something felt off.

"I'm not here to hurt any of you. If I was, you'd all be dead by now." Percy sighed. His tough demeanor wavered a bit. "I'm here just to show Annabeth that, yes, I'm alive, and to call off the Hunters looking for me. I don't want them to get hurt." Percy continued, wlaking around the room.

"I doubt that." Dean growled at him. At this point, he knew nothing could stop Percy, so the gun was more for comfort than anything. Percy rolled his eyes and flicked his hand, grinning ever so slightly as the gun flew to his hand.

"They are led by my cousin Michael's Sword. I don't want her dead." Percy clicked his tongue as he tapped the gun against his chin, studying Annabeth, smirking as Dean winced at his words.

"My dear Wisegirl. You really have forgotten to take care of yourself, haven't you?" He asked, noting the dark circles under her eyes and the tangles in her hair as he walked around the room. Annabeth's stormy eyes flashed.

"You don't get to call me that." She said defiantly. "Only Percy does." The demon sighed, and spread his arms as he turned away from Semouyr to look at the group.

"I am Percy, daughter of Athena. Just not your Percy." He flashed her a smile. "I never was." He added. "You see, my little brother was correct in saying I believed I was a demigod until I was around 17. But what he doesn't know is that I had been hearing angel radio, so to speak, since I blew up Mount St. Helen." As Percy spoke, he gestured with the gun wildly, causing everyone else to duck more than once. He paused for a moment, letting his words sink in. As soon as the words had registered, Same made a choking noise.

"You caused that?" The hunter managed, staring at Percy, which only warranted an eyeroll.

"Yes, Sammy, I caused that. Isn't that what I just said?" He said. Sam made a slight face, but kept himself from saying anything. While Percy's back was turned, Dean pulled out the demon knife. He might have promised Cas to trust him until he proved himself untrustworthy, but Percy was not making it easy.

"Anyway, Calypso's magic was strong enough to break the barrier separating my mind from angel radio, but not enough to bring back my memories." Percy explained, completing his circle around the room, stopping next to the Pac-Man machine. "I thought it was something that happened once you were that close to death, and that it would go away after a bit. But it never did." Percy shook his head, in something akin to regret.

"Why did you never tell me?" Annabeth demanded, fingers tightening around her dagger hilt.

"What would you say to someone you liked, if you thought you were going crazy?" He asked, his voice harsh as he stared her down. "What would you say, to someone you loved Annabeth?" When Annabeth went to answer, she caught his gaze and almost gasped outloud. His sea-green eyes were filled with so much pain, suffering, and anger, it was no surprise anymore why he was acting like this. Sure she knew he was a demon, but she had never met one, so she had nothing to compare it to. Percy moved his gaze to look at Chiron.

"My dear old centaur. How difficult must it have been to lose one of your favourite students, especially so soon after the son of Hermes death." Percy drawled, eys flashing black for a fraction of a second. This didn't surprise Chiron- nothing did anymore- but it did sadden him. The centaur didn't answer, instead casting his gaze at the floor. Percy rolled his eyes and stretched, tossing the gun back at Dean.

"I've done what I came to do." He shrugged, watching the gun fly back to the Winchester, who caught it with a surprise grunt. Cas watched his brother, an uncommon worried and sad look on his face.

"Don't look so down little brother. You'll see me again. Toodles" Percy laughed, and disappeared in a cloud of mist. In his place, a note fluttered towards the ground. Sam was the first to react, snatching up the note as Annabeth turned to Chiron. Quietly, she spoke.

"That isn't Percy." She told him, a fear he had never seen before in her eyes. Chiron looked at the daughter of Athena with sad brown eyes.

"It is his soul, his body. It may not seem like it my dear, but that is Perseus." He spoke softly. Annabeth shook her head defiantly and turned back to the hunters and angel.

"Well? What does it say?" She demanded, refusing to look at Chiron as he clopped up next to her. Sam opened the folded piece of paper and read it aloud.

" 'Something I couldn't say outloud. Angels everywhere are looking for me, now that they know I'm back and they would've heard me. They will know that I have been at Camp, so I suggest you put warding on Thalia's Pine, and each of the cabins, plus the Big House. Also, you should probably get the remaining Seven, plus Thals, Neeks, and RARA together. A war might be coming your way and you need to be ready.' " As Sam read the note, a small smile came onto her face. When the younger Winchester finished reading th enote, he looked up the the Camp Half-Blood occupants.

"Who are the people he mentioned?" Annabeth lenaed over and snatched the paper from him, and scanned it for herself.

"Freinds, Family. People who helped us defeat the giants and Gaea." She explained.

"The Greek Goddess?" He asked, confusion spilling over his face. Dean raised an eyebrow.

"Mother Nature, evil? I doubt it. And even if she was, I doubt a few teenagers could beat a force that powerful." He scoffed, knowing he shouldn't, but he couldn't believe that a couple of teenagers had defeated someone so powerful. Sam looked at him, eyebrows raised in surprise.

"And you say I'm the nerd." The younger Winchester laughed as Dean scowled at him. Annabeth turned to him, eyes half blazing with anger.

"Yes Dean, and we would all be dead if a few teenagers hadn't almost died, and if two of us hadn't gone through literal Hell." She told him calmly, but her eyes told a different story. They continued to blaze with anger, but hidden within the depths was a saddness, an emptiness, that Dean knew all too well. It was one he saw everytime he looked in the mirror. Moving away from the hunting trio, Annabeth turned to Chiron, avoiding his eyes.

"I will IM the Hunters. You message the remain seven, along with Reyna." He spoke softly. Annabeth nodded at him and looked over her shoulder at Cas, Sam and Dean.

"Sam, come with me. I'll show you what IMing is. Dean, Castiel, you stay with Chiron." Without waiting to see if Sam was following her, Annabeth spun on her heel and walked away from them. Sam scrambled after her, while Dean and Cas looked to Chiron. The centaur turned his sad brown eyes to them.

"We have a lot to discuss. But first, we do need everyone here."
