Although he would later deny it, Dean Winchester found himself completely at a loss for words. This, of course, doesn't happen often. In his lifetime, Dean had lived through so many, frankly bizarre, experiences that he felt nothing could surprise him anymore. He had been to Hell for Christ's sake! He traveled through time and fought demons and basically has an angel on speed dial. But this, this was something new. Again. Jesus, he was getting too old for this shit.

In his shocked silence, Dean stared at the kid for a long time. Probably too long, he should have acted by now. Survival is often guaranteed to those who act quickest. But damn it, he was tired. They have a leviathan tied up in the basement of Rufus' cabin and Sam is still hallucinating and all Dean wanted was a walk to clear his head a bit. But he stood on the bank of a shallow creek, staring at the kid sitting in the water. The kid stared back. He didn't look afraid exactly, but he seemed to be waiting for Dean's reaction. However, at that moment Dean didn't have a reaction to give. He watched as the cut on the kid's forehead slowly closed and disappeared, as if it were never there. When it became apparent that Dean wasn't going to speak first, the kid stood up from the knee deep water. Keeping half an eye on Dean, he approached the headless body of the leviathan, floating listlessly nearby and nudged it with the toe of his sneakers. Black ooze seeped out of the severed neck and he made a face.

"Huh. Normally the monsters dissolve, or explode or something." He commented thoughtfully, a New York accent evident in his voice. The kid's words broke the silence and pushed Dean out of his shock and back into action. He brought up the gun, previously hanging loosely in his hand, and pointed it at the kid. The kid immediately stepped back; his hands flew into the air.

"Whoa! Ok, it's cool, dude. It's cool, just—"

"How did you do that?" Dean interrupted, "Where'd your sword go?"

"Do what? What sword? I don't know what you're talking about." The kid's eyes were fixed on the gun. Dean wasn't impressed.

"Look, kid—"

"Percy." The kid said.

"What?"

The kid gestured loosely to himself. "My name is Percy." Dean threw a hard look at the kid, who gave him a little shrug and dropped his hands to his side.

"Whatever, fine. Percy. You can't bullshit me. I saw the sword and I saw the water. Water doesn't move like that. I didn't move the water. The Levi didn't move the water. That leaves you."

"Levi? Is that what they're called?" Percy glanced back at the floating corpse with interest.

"Leviathans."

"Oh. I've never heard of those before."

"Well they're sort of new." Dean said, "Hey, don't get off topic. You were explaining yourself." Apparently Percy no longer felt threated by Dean because he stepped out of the creek and picked up the backpack he had dropped on the ground.

"And you can see them." Percy said.

Dean lowered his gun but didn't put it away. "Of course I can see them. I also saw that sword you pulled out of nowhere. What kind of kid carries around a sword?"

"I'm almost twenty, thanks. But you must be clear-sighted then." Percy commented as he dug through the pockets of the bag. Dean could feel himself quickly losing control of the conversation. Over in the creek, the leviathan's detached head began to make its' way back to the body.

"My eyes are fine."

"I can tell." Percy said. He looked up from his bag. "Have you seen my phone?"

"No. Now tell me about the sword. You didn't have it when the Levi first attacked and you don't have it now, so where do you keep it."

"I could tell you, but then I would have to kill you." Percy said. Dean rolled his eyes.

"C'mon, kid."

"Percy."

"Whatever."

"Do you want the truth?" Percy paused in his search for the phone.

"Yeah."

"You can't handle the truth." Percy said. He grinned when Dean kicked a rock in frustration. "You kinda walked right into that one, dude."

Percy jumped back into the creek and began feeling around for his phone in the water. He absentmindedly kicked the head away from its' body again. "Do you mind helping me look for it?"

Dean wasn't quite sure what else to do, so he tucked the gun back into the waist of his jeans and started sifting through the leaves on the ground with his boot, looking for Percy's phone.

"What are you even doing out here?" Dean asked, switching tactics.

"I could ask you the same question."

Dean rolled his eyes and swept his foot through another pile of leaves. "I have a cabin near here."

"Oh. In that case, I got lost. Must have took a wrong turn." Percy said, still searching for his phone. Dean thought about pointing out that the nearest town was easily twenty miles away and the nearest road was a good half hour of a walk, but felt it wouldn't really change the kid's answer. Percy was now on his hands in knees in the water, sifting through the rocks at the bottom.

"Hey! I found it!" Percy stood quickly, holding a small flip-phone triumphantly in his hand and shaking the water off. He opened it and grinned when the screen lit up. "Sorry dude, but I gotta go. If I'm late my girlfriend is totally gonna flip shit." Percy climbed out of the water, picked up his bag, and slung it over his shoulder.

"At least tell me what your sword is made of." Dean pressed again. Percy looked up from his phone.

"It's a special kind of bronze. Kinda rare." Percy said sympathetically. "Look, sorry I can't help you with your monster problem. If I were you, I'd bury the head somewhere deep and then burn the body. That might work."

Dean grimaced as they both stared at the twitching body in the creek.

"Well, I gotta go. Like I said -girlfriend- can't be late." Percy said, "Nice meeting you…" He trailed off expectantly.

"Dean."

"Dean. Yeah." Suddenly Percy's phone began to ring. He glanced down at the number. "Styx." He muttered.

"Hey, Annabeth! Yeah, I'm on my way… No, I totally left on time… I just hit a little speed bump on the way. Got lost. Took a wrong turn." Percy held the phone away from his ear. "Dean, where are we right now?"

"Montana."

"I ended up in Montana… I don't know how… No! The map you drew was fine…" As he talked, Percy casually away from Dean and the scene where, just moments ago, he wrestled and beheaded a prehistoric monster. Abruptly, he stopped and turned back to Dean.

"Oh, um… good luck with your monster. Bye." Percy gave a two finger salute and spun back around. Dean watched as he disappeared through the trees, still placating, who Dean assumed was his girlfriend, through the phone. When he was gone, Dean turned back to the headless Leviathan in the stream. He grimaced.

"How am I gonna explain this one to Sam?"

Welp. I'm not really sure where this came from. But I hope you enjoyed this one shot. I was too lazy to do anything actually productive today so here this is. Shoot me a review if you want to see more close encounters between the Supernatural crew and the demigods because these little stories are quick and fun to write.
