He was one nasty son of a bitch.
Dean stared at the demon trapped in the circle. He was already twitching from the words that Sam was reciting, the smoke billowing from beneath his collar. Dean hoped he had a long, painful trip back to the Pit.
"It's not going to end this way," the demon said through gritted teeth.
"You keep telling yourself that." Dean circled the trapped demon, his gaze occasionally flickering upward to keep an eye on Sam. He knew it was silly for him to keep thinking Sam came back wrong, but he kept looking for that reassurance away.
Sam, appearing none the wiser, kept up the exorcism, just like he had always done. Dean allowed his gaze to linger, double-checking just one more time, before he went back to stalking the demon. Only this time, he found the demon smiling. He wasn't smiling to taunt Dean, or mock the situation. This was a full smile, one gleaming with hellish delight only reserved for a demon, and that joy was focused solely on Sam.
Dean felt his back prickling. Angry, he stepped closer to the circle. "What the hell are you smiling about?"
The demon ignored him, eyes only for Sam. He chuckled even as he stood there convulsing. "If you're not going to step up to the plate, then we'll find a way."
Dean grunted and threw holy water in the demon's face. "Don't you talk to him." He turned his head, trying not to show concern that Sam had stopped. "Sam?"
Sam went back to reading the exorcism. Once again, Dean started his slow stalk around the circle. There was something about this demon that set him on edge. Not that they all didn't, but he didn't like the way this one seem so focused on his brother, so intense and determined.
Dean was so busy staring at the demon he nearly missed the item in the demon's hand. His eyes widened. "Sam!"
The demon chucked the stone at Sam. Even as Dean bolted over to Sam to intercept, it was too late. Sam looked up, saw the stone, his natural reflexes kicking in as he caught it. As soon as the stone touched Sam's hand there was hearty rumble, like the ground was splitting, and suddenly Dean found himself ripped sheer across the room by an unseen force.
He braced himself for impact. Dean's body hit the wall full force, his head cracking against the cement. He felt his body slide against the wall as it slumped to the floor. Little dots of white flashed before his eyes before they were quickly consumed by a growing blackness. He struggled against the coming darkness, the numbness and the detachment, as he saw Sam's confused face split and distort under his failing vision. Then, everything around him went into a dead silence and he was gone.
An urgent tugging brought him back.
"Dean." A shake. "Come on, Dean."
Dean groaned. Everything seemed to echo around him and there was a painful, sharp throbbing at the back of his head.
He reached up to touch the source of the pain and winced. He could already feel the lump forming under his hair. With a sigh, he slumped back against the wall. He just wanted to drift off again.
He felt a sharp digging pain in his shoulder as Sam shook him again. "No. Get up."
It took effort, but he finally willed himself to open his eyes.
Two Sams danced in front of him.
Dean scowled. "Fantastic. I'm seeing double."
One of the Sams grimaced, but the other didn't. Dean wasn't sure what kind of double vision could do that sort of trick, but he thought it was kinda neat. In fact, he thought it was funny and all kinds of awesome until the other one dug his fingers into his other shoulder.
The smile wiped clean from Dean's face. "What the hell?"
The identical Sams sighed in unison. "We have a problem."
