Summary
Ah, well. Dean figured Alastair would get impatient eventually.
As if on cue, the basement door swung open. A part of Dean tensed, his muscles ready to leap into action but Dean knew better. He forcd himself not to move, to remain at least a picture of calm.
Until a body was flung down the stairs.
Dean blinked.
Blinked again.
“Well that's new,” he mused out loud to himself. And then he realized it was Alastair. He hummed, jumping to his feet. “Definitely new.”
A set of footsteps started down the steps and he waited with bated breath, not quite sure what the hell was going on but eh. He’d learned to roll with the punches.
And boy, what a punch this was.
It hit him right in the gut even.
The man walking down the stairs was beautiful.or. Dean is accidentally captured by the guy he was gonna murder and is saved by his angel

Summary
He finally notices the body laying prone near his feet, the strange blue-eyed Alpha kneeling next to it. The body is sprawled across the path, the Alpha halfway on the path, halfway covered by the trees next to him. The Alpha’s pretty eyes are wide in surprise and Dean doesn’t have time to even think as words break through his mouth.
“The fuck? Couldn’t have done this away from I don’t know, the path that people walk on?”
Jesus fuck. Dean might have a death wish he’s realizing as he notices the Alpha holding a fucking butcher knife in his right hand, raised over the again, fucking body at his feet. Blood is dripping from the blade and even still Dean isn’t afraid.
God, he’s broken, isn’t he? Finally happened. Dean finally fucking snapped.Or
The silly fic I decided to write where Dean interrupts Cas committing a murder and gets heart eyes for the hot ass alpha.

Summary
Like the wood, he was stained. It caked under his fingernails, in the creases of his skin, discoloring his flesh just like it had the lamb’s soft wool. His thoughts flickered to memories that he hadn’t touched in years—his father’s cold stare, the harsh crack of a belt, the smell of whiskey mixing with that of mildew and rot.
Dean clenched his jaw, pushing the thoughts away. Not now. He didn’t have time for that today. After ensuring one last time that there was no trace of the event left for his parishioners to see, with shaky hands Dean lit the candles as he had originally intended to do, clinging to the normalcy of this routine as if it would cleanse him.

Summary
“Don’t come any closer."
The man stops his approach. “Or you’ll… throw a book at me?”
The stranger’s eyes follow the chain from Dean’s ankle to the wall and then centers back to him and the book. He can practically hear the guy thinking something like, ‘what good is a book gonna do you when you’re chained up like an animal?’
“Are you gonna kill me?” Dean hesitantly looks up. It’s a little disorienting to be met with the biggest kicked-puppy-eyes he’s ever seen before. He didn’t expect that sort of expression on the face of someone who was choking a guy to death a few minutes ago.

Summary
Castiel Novak is a solitary creature. Corporate engineer by day, serial killer by night, and always by himself. Just the way he likes it.
Until a new coworker's long, bowed legs, green eyes, and crooked smile catch his eye.
He's certain he'll have to kill Dean, at first. He can't afford distractions, living the double life that he does. When the time comes, though, he just can't bring himself to do it. Artistic inspiration, long dormant in Castiel's life, replaces murderous intent.
As his obsession grows, so too does a newfound wish that he could share the deepest, darkest depths of himself with Dean. That Dean would understand, would accept, would even celebrate Castiel's bloody inclinations. But that's absurd. Unthinkable. Dean isn't like that.
Is he?
