By the time Sam got Chase within his sights again (although staying unnoticed), the other guy was clearly visibly upset.

He was yelling at one of the rainbow images, which by now Sam assumed was basically like video calling.

In it, Sam could see Nico, who looked visibly flustered. In the background was a room much like Sam expected Dracula's would have lived in -all dark and creepy, like a mythical vampire.

"Why the hell didn't you tell me they were here?" Chase yelled.

Nico shrugged. He looked vaguely apologetic, but mostly like he thought things would end up good so he wasn't too concerned with his current situation. "Surprise?"

Chase looked like he was about to strangle Nico.

"Gah!" He yelled. Sam wouldn't have been surprised to learn that Bobby and Dean could have heard it from inside the house. "Nico, this is not a good surprise! You know who Sam is!"

Apparently Nico finally hit his breaking point. "Yeah, I do! That's exactly why I sent you, of all people! You need to deal with this!"

Chase grabbed his hair in frustration. "I can't, Nico. Not with this. Besides, I can't stay here. I can't fight the things that the Winchesters do. These monsters, they're just... they're not like the ones we're used to. They're too unpredictable, at this point. Nobody really knows anything about them. And our campers can't all fight them. Actually, none of them can!"

Nico sighed. Without answering Chase, he said, "The Hunters have started dying."

Chase stilled. "No."

Nico nodded. "Annabeth told me. It's why I came here, why I left you mostly in charge over there."

"Why?" Chase demanded. "What's killing them?"

Nico looked worried. "That's the thing... we don't know. Every night, one of the girls ends up dead, and Artemis is MIA. We can't contact her, and even Mr. D is getting worried. He seems actually scared."

Chase groaned. "Well this is just getting better and better." The sarcasm was just like Percy, same inflections and everything. Again, it made Sam wonder if Percy had ever had any family that he just hadn't talked about (Sam definitely remembered the wild stories about Aunt June) because Nico, and now Chase, acted a lot like him.

Except... Chase didn't look anything like Percy. His hair and eyes were similarly colored, but his facial features were way different.

Chase had started pacing around, walking in circles while Nico watched him gravely. He was visibly upset at this point, more than just yelling. He had a lot of nervous tics, it looked like, that were exactly like Percy's, like the drumming of his fingers, so Sam recognized it easily. "I can help, Nico! Why am I stuck over here? I'm one of our best fighters, and the gods trust me, I can be doing so much more. I made it through Tartarus, why can I not just help?"

"Because you're forgetting that adept though the Winchesters may be, one of them has died before, and it turns out that Celestial Bronze works on demons. You're more help there than at camp."

Chase stopped wandering around and stared Nico down. "...Fine."

"And one more thing," Nico added. He whispered something that must have been Greek again because Sam couldn't make out any familiar words. Except—was that Perseus? Chase's eyes widened, and Nico laughed. "See ya, Chase."

He waved his hand, and the rainbow fizzled out of sight.

Chase didn't move for a moment, still staring at the spot the rainbow had been in, before he spun around, so he was facing the Sam's direction. "I know you're there." He called. Sam didn't move, hoping that maybe Chase was bluffing. "Dude, really? I mean, whatever, if voyeurism is your thing, I'm not gonna judge, but seriously can you at least quit hiding? It's annoying. Besides, it's not like you heard anything you weren't supposed to. I've got no evil plans, promise."

Sam walked closer, and Chase sighed. "What do you need?" He didn't look at Sam for very long, though, and again his eyes slid away, so he was looking at his shoes.

"I heard yelling." Sam answered. "It seems like you don't want to be here."

"Well, I mean, this isn't my favorite place, but I've been in worse. I'm not gonna die here." Chase seemed far too casual, but the way he fidgeted said he really didn't want to be talking to Sam right now.

Sam decided to ask. "Tartarus?"

Chase winced. "Okay, so maybe you weren't supposed to hear everything."

"It is actually Tartarus? Like, the Greek hell?"

Chase turned his shoulders slightly, and kept his head down. There was a long moment before he spoke, and then, "Yeah. Exactly like that. But worse than what you're imagining. A hundredfold worse than the most horrifying stuff you can think of."

Sam wasn't sure. He had seen some pretty awful stuff, having practically been raised hunting, and now that he was with his brother again, it wasn't exactly as if all the monsters became nicer.

Before he could open his mouth, Chase spoke again. "And yes, I'm aware of what you do for—well, not exactly a living." He chuckled lightly. "But whatever. I'm going inside. Have fun staring at cars."

He turned and walked away without another word, heading back in the direction of the house.

.:~*~:.

"Excellent job with the witnesses. Although, you seemed to have some help."

"You were hip to all this?" Dean asked. He was suddenly much more irritated.

"I was, uh, made aware." Castiel answered.

"Well, thanks a lot for the angelic assistance. You know, I almost got my heart ripped out of my chest."

"But you didn't. And you received help, even if not from us."

"I thought angels were supposed to be guardians. Fluffy wings, halos—you know, Michael Landon. Not dicks." Dean said, narrowing his eyes.

"Read the Bible. Angels are warriors of God. I'm a soldier." Dean noticed he tilted his head slightly, as if listening for something. After a moment, his gaze flickered to some corner of the kitchen.

"Yeah? Then, why didn't you fight?" Dean challenged, ignoring whatever it was that the angel was sensing.

"I'm not here to perch on your shoulder. We had larger concerns." The words seemed careful now, measured.

Dean was getting edgy, but he did his best not to show it. "Concerns? There were people getting torn to shreds down here! And, by the way, while all this is going on, where the hell is your boss, huh, if there is a God?"

"There's a God." Without answering his actual question, Dean noticed. Just confirming the existence of something bigger.

"I'm not convinced. 'Cause if there's a God, what the hell is he waiting for, huh? Genocide? Monsters roaming the earth? The freaking apocalypse? At what point does he lift a damn finger and help the poor bastards that are stuck down here?"

"The Lord works..."

"If you say 'mysterious ways,' so help me, I will kick your ass. So, Bobby was right... about the witnesses. This is some kind of a... sign of the apocalypse." There was a faint noise. Dean spun around to look at the living room, but everyone was still sleeping. Chase was still off in the corner, motionless.

Dean looked again. Chase was gone, and it was just a pile of books, covered with a blanket. How had he mistaken that for Chase?

He turned back to Castiel, who was actually smirking slightly. Smug bastard.

"That's why we're here. Big things afoot." And now he was actively making fun of Dean.

"Do I want to know what kind of things?" Dean asked.

"I sincerely doubt it, but you need to know. The rising of the witnesses is one of the 66 seals." The angel answered gravely.

"Okay. I'm guessing that's not a show at Seaworld." Dean said.

There was that noise again, only it was louder, clearer. It sounded like someone was laughing at him. Dean spun around again, and the other room was exactly the same. And Chase was still missing.

"Those seals are being broken by Lilith." Castiel seemed oblivious to the noises.

"She did the spell. She rose the witnesses." Dean said, still watching the other room.

"Mm-hmm. And not just here. 20 other hunters are dead." Castiel agreed.

"Of course." Dean realized, turning to face the angel again. "She picked victims that the hunters couldn't save so that they would barrel right after us."

"Lilith has a certain sense of humor." Castiel turned his head, focusing on something, this time intently. Dean spun around, fearing the worst, and saw Chase standing there.

When Chase saw Dean's attention on him, he checked himself.

"Oh." He said. "I'm corporeal."

Dean looked at Castiel again, and saw the angel nodding. "Yes, Jackson. You're also invading."

Chase crossed his arms (and Jackson? Was that his last name or something?) and made a face. "Well, it's not like I can help it or anything. Usually, though, people just don't notice me."

"I am not people." Castiel replied. "I noticed you nearly as soon as you fell asleep. However, I don't know why you've solidified enough to become visible to the human."

"Hey!" Dean said. He was ignored, though.

"Whatever, dude. One way or another, it doesn't particularly matter. But still. Seals? What happens when all the seals break?"

"Lucifer walks free." Castiel said.

"Isn't that the cat in Cinderella?" Chase asked.

Dean liked Chase just a little bit more.

However, Castiel just rolled his eyes. "No. Lucifer is a fallen angel, and despite your parentage, he'd squash you like you would a bug."

"Okay." Chase said. "But he can't really be worse than the giants, can he?"

"Yes, he is." The angel answered simply.

"Wait, wait, what? Giants?" Dean asked, incredulous. "And who the hell are your parents?" He didn't understand anything that was going on. And the mysteries connected to Chase seemed to only be piling up.

Chase turned to face Dean. "Listen, I promise I'll explain everything, once I can actually trust you. But for now, you're gonna be confused, and there's a lot you can't know."

"Do you really intend to keep all of that a secret for so long? What are you going to do without the Mist?" Castiel asked. He was staring intently at Chase, as if trying to see deep into his soul. Maybe he was. Who knew, with all the freaky angel powers

Chase turned—well, stink eyes was the only really way to describe it—on the angel. "It isn't any of your business, angel. Aren't you above such pesky mortal things, anyways?"

"I am involved, because whatever you do will influence the Winchesters." Castiel hesitated. "Make the right decisions. I will not have you destroying them."

The angel disappeared.

And Dean opened his eyes, feeling a distorting sense of vertigo as he was suddenly sideways on the ground, waking up.

Sam was in the kitchen, awake already and making eggs, and Chase was standing silently in his corner, watching Dean.

As soon as Dean saw him, Chase walked over and helped Dean up. "What happened in there-" he tapped Dean's forehead harshly. "-is none of your business. Don't ask about it."

He walked away, into the kitchen, smiling brightly. When Sam's back was turned, he added a dash of salt and something else to the eggs, and stirred it quickly.

And then he snapped his fingers, and Dean forgot what he had just been doing.
