The weaknesses of angels are not well known. Angel blades and holy oil being the most common, but there are some other rarer things. Things irresistible to angels, things hardly known to man at all. It was the scent that caught his attention, and the song that lured him in. The pull was strong enough to pull him off his assignment. To pull and angel away from an order was an unearthly power. Something almost as strong as angel's themselves possessed it. His senses led him to a small rocky island in the middle of Lake Superior. The trench coat flapped in the wind as cold water sprayed at his face. This place was something too barren to be habitable by anything human, too cold and harsh to sustain life. Yet out of the dark surf walked a being of ethereal beauty and unparalleled horror. The angel could not look away. He could not run away. Her skin was translucent and giving off an eerie glow, as if she was a jelly fish that became human. Her hair was the color of the angry water, long and clinging to her body. She held out a hand of long lethal claws webbed together with filmy skin to the angel, and led him into the small wood on the island. He did not resist, he did not pull away. His eyes never left her face, he noticed she had demon eyes, but this was unlike any demon he'd ever met.

"I never want to hunt another sasquatch again."

"Who knew those suckers would be so hard to kill."

"And the smell!"

The brothers shook their heads in mutual disgust.

"Aww, first bear hunt?" The waitress well past her prime asked as she walked to the table.

"Yeah, something like that."

"Never quite is what you expect. What can I get you boys?"

Before they could answer, a boy no older than 19 walked up to them. He was the color of creamed coffee with almond eyes and wild hair. He carried with him a surreal calm.

"Leave us," he commanded the waitress. She left as if I hypnotized. He made a motion for Dean to scoot over so he could join them in the booth.

"Uh, can we help you?" he asked impatiently.

"You are friends of Castiel."

The brothers looked at each other uncertainly.

"I'm his brother, Remiel."

"Great, more angels. What's this about, Remi?"

"Castiel is missing."

"He's what?" voicing their belief in unison.

"He is hidden from us. We are not able to track him. He never made it to, nor returned from his mission. He was last seen in this area. It was decided that you may be of help."

"And what if we're not?" Sam asked tentatively.

"Then we assume Castiel is lost. We have been searching for three days."

"Only three days?"

"Three days to you is akin to a year to us, Samuel Winchester. Time is relative to the being."

"It's just Sam."

"So you guys are just going to give up on him? Just leave him to die? Some family you are."

"I was told you have a special attachment to Castiel," he looked at Dean who looked like he was about to shoot flaming holy oil out of his eyes at the angel.

"What of it."

"You may know where he has gone."

"I haven't seen him since before he disappeared."

"So then Castiel is lost," something flashed across his face, a hint of emotion for a fallen brother. "Thank you for your help."

The two men were left alone in the booth, neither had an appetite left. They left and drove back to their motel in silence. Sam was desperate to help his brother; Dean was desperate to help Castiel.

"Dean, do you think Cas has that phone you gave him?"

She whispered enochian in his ear, promises of things more beautiful than he'd ever seen. Long rituals are hard to complete when you can only live in the dark. He stayed, he wouldn't disobey her, couldn't disobey her. He had to stay, see her again. He could not see anything beyond the island, or hear, or feel. His grace blocked by something he'd never felt. But it was nice, so nice and silent. No one calling to him, or ordering him. He just sat and watched the sun move across the sky and waited for her return. When the sun dipped below the horizon and she stepped out of the violent lake he followed her back to the wood. He would sit on the altar she had carved out of the ancient stone with her malicious hands and she would groom his grace. Her claws laced ancient threads of magic through his grace, through his feathers and down to the tips of his wings. They were gentle, she sang to him as they branched out through him, her voice dulled the pain. The choking vines spidered through his grace.

"Soon," she keened in a voice that sounded like water trickling over pebbles. He couldn't wait for the time to come, though he was unsure of what it would bring.

"Listen, I'll give you $1000 right now if you take us to that island."

"Do you not see the storm brewing? It's almost dark, it'd be suicide."

"Do you not see the size of my fist?" Dean was frantic.

"What will it take for you to do this?"

"$2500."

"It's yours. Let's go," Dean said shoving past the man onto the boat. He was less a fan of water travel than he was of flying, but Cas. "Thank god for GPS. That was a good move, Sammy."

"I know how important he is to you," He put a hand on his brother's shoulder.

"Hey, no chick-flick moments."

Dean's nails had been chewed to the flesh. He hadn't stopped nervously fidgeting since Remiel had left. He didn't know if it was the rough water making him nauseated or the thought of Castiel being hurt.

"We're almost there. I wasn't sure if there was still a dock on that island, but lucky for you crazy bastards I called a buddy in the coast guard and he said there still is."

Within an hour they were docked, finally on solid ground Dean could breathe again. It was late, the clock on his cell phone read 3:37am. He grabbed a flashlight and stumbled around the rocky coastline calling to his angel.

The angel could not hear the voice crying his name. He could only hear the song of the mermaid lacing her tentacles into his grace to steal it.
