Disclaimer: Dean, Sam, Alec and any characters from the TV shows Supernatural and Dark Angel do not belong to me in any way (sadly). I am just playing with the characters. This story is written purely for enjoyment, with no profit of any kind expected, intended or desired.

As I'm doing a crossover this is going to be AU for both series, although events up to the start of the story will remain as canon as possible for both Dark Angel and Supernatural.

I want the boys to be fairly close in age for the purposes of this story... So I'm pulling Alec into the story aged about 20/21, sometime just after The Berrisford Agenda. Dean and Sam will be pulled from early season 2 of Supernatural, making Dean approximately 26/27 and Sam therefore 22/23.

This obviously shouldn't work as season 2 Supernatural is set back in 2006 and Dark Angel is in the future, but the answer to this mystery forms part of the story.

Seeing Double

Chapter One

There was something unyielding and cold pressing into his cheek bone… or maybe it was his cheek bone that was lying on something… yeah, that's it, thought Alec, his faculties gradually coming back on line. He was lying on a concrete surface and it was cold, cold and wet. He shuddered involuntarily, feeling around him with his heightened senses. He couldn't detect any immediate threats so he opened his eyes slowly.

He was lying in an alleyway. It was dark where he lay, just outside the pool of light from the main street. He remembered feeling odd, dizzy, turning into the alley on his bike, away from the street and curious eyes.

He pushed himself up to a sitting position, leaning his back against the rough bricks behind him. His cat DNA allowed him to interrogate the shadows with ease and informed him that his bike and packages were gone. Normal was going to be so pissed.

He climbed slowly to his feet, bracing himself against the wall. He felt weak, dizzy, nauseous, his head pounding. He checked himself over carefully… no injuries. It didn't feel like the onset of the shakes and transgenics weren't meant to just get sick, not with their enhanced immune system.

Carefully, Alec took an experimental step; he nearly fell and dropped against the wall, panting. All his muscles were hurting and his legs were shaking so much he wasn't sure he was going to be able to make it to the end of the alleyway let alone back to his apartment on foot.

Unwillingly he pulled out his cell. He didn't want to call Max and he'd never hear the last of it, but she'd come if he asked. He flipped open the cell; the screen was white, blank. "Great," he thought. "Just… great."

He moved slowly, shakily towards the end of the alleyway, grateful it seemed relatively clear of debris. By the time he reached the end his vision was tunnelling and he gripped onto the brick corner with desperate fingers. The street seemed… tidy? Neat pools of light showed a swept sidewalk, no garbage, no graffiti.

Directly in front of him was a beast of a car. Even in his weakened state Alec felt appreciation for her sculptured lines and the dark gloss of her paintwork and chrome. A figure straightened from the trunk, slamming the lid.

Alec took a shaky step forwards and the world flipped; vaguely he felt the impact as the side of his head cracked sickeningly onto the sidewalk. There was a muffled curse and then someone had hold of his shoulder.

"Hey buddy, you okay there." A deep growl of a voice, oddly familiar even through the ringing in his ears.

Strong hands took hold of his shoulders, rolling him onto his back. There was an expletive, followed almost immediately by a sharp slice of pain across the back of his wrist. Alec tried to protest but couldn't get out much more than a grunt. His eyes shot open in shock as something cold and wet splashed into his face.

The dark silhouette leaning over him sighed. "Sorry kid, gotta be sure." Firm fingers took hold of his jaw, rolling his face towards the light. There was an intake of breath, a grouse of "What the hell are you?" as hands checked over him in a pattern he recognised from field first aid.

Alec began to float, his eyelids sliding down.

"Sonofabitch! I should just leave you here, but that's not your face."

Alec felt a surge of panic, struggling as hands slipped beneath his shoulders and knees. He couldn't think of any good reason why some stranger would pick him up because of his face.

He was swung up into the air, cushioned against leather. He tried to pull free but pain and nausea swept through him.

"Keep still, you're heavy dude."

The ease with which the man carried him made a lie of the words as Alec went limp, his head rolling to the side, forehead coming to rest under the man's jaw. A familiar and oddly safe scent filled his nostrils. The smell of his own skin under the summer sun, his own scent, but not. This was no transgenic. The temperature of the skin alone told him that.

There was a moment of weightlessness and then he was down, folded carefully into the passenger seat of the shiny, black car. He whimpered, hating that he had made a sound and hating his own vulnerability.

The driver's door slammed and the vehicle snarled into life with a deep rumble. Barely conscious now, Alec rolled towards the familiar smell, his head coming to rest on the leather seat close to the man's leg.

"Well this is just awesome." The voice grumbled even as something warm was tugged over his shivering form.

Alec curled in on himself as the vehicle surged forwards, giving into the darkness and slipping away into silence.

Continued in chapter two…
