125. Silver

"The shifter got away," Charlie panted, leaning against the wall. Sam, Dean and Castiel glanced around at each other suspiciously.

"C'mere, Charlie." Dean took Charlie's arm, took her leather-hilted silver knife and made a shallow cut. Charlie winced and hissed at the pain but she didn't react like a shifter would, so Dean stepped back and let her wrap up her bleeding wound. He turned to Sam, who easily held out his arm and let Dean test him. Castiel knew that he was next, so he willingly held his arm out. But something was wrong. Dean's grip was too firm and he carelessly made a slash on Castiel's arm, rather than gently nicking him like he always did. Castiel frowned at Dean and something changed in his green eyes.

"Sam, Charlie," Castiel said warningly. "He's –"

But before he could finish, 'Dean' tightened his grip on Castiel's wrist painfully. In a blur of motion, Castiel found himself pinned to the shifter's chest, his wrist clamped in a vice grip and the silver knife glinting threateningly in front of him.

"Where's Dean?" Castiel snarled.

"Dean's a little…tied up at the moment," the shifter said lightly, tapping Castiel on the nose with the knife. "So I'm in charge now. I promised him I'd have lots of fun with his angel. I wonder what I should do first. A few cuts?" Castiel let out an involuntary sound when the shifter made a long slash down his face from his eye. "Maybe some broken bones?" He squeezed Castiel's wrist until a popping sound was heard and the ex-angel cried out.

"Just leave him alone!" Sam snapped, taking a step towards them. But, quick as lightning, the point of the knife was resting just below Castiel's right eye.

"Dean loves his angel's pretty eyes," the shifter taunted. Castiel tried to ignore how the monster was using Dean's voice but it wasn't easy. "So bright and blue…wonder what he'd say if I carved them out?"

"He wouldn't like it one bit," an identical voice said. The shifter whirled around, dragging Castiel with him, to see another Dean, with a swollen face and a pissed expression. "Let go of Cas and back off. Now."

He raised his silver knife threateningly. Castiel attempted to take advantage of the shifter's distraction and free himself but the shifter seemed to have all of Dean's knowledge about him because he tightened his grip, sending pain lancing through Castiel's wrist, and slashed a bloody trail down Castiel's face from his eye. Castiel stiffened. This was different from the other monsters that had taken him hostage. This one knew all his tricks, knew everything about him, and without the ability to see the horrible creature underneath its skin, Castiel didn't know if he could kill it while it looked like Dean.

"Sorry, angel, but I know all your tricks," the shifter tutted, tapping the point of the knife underneath Castiel's other eye. "Now quit squirming or I'll make you look like Bloody Mary."

"I said let him go!" Dean barked, his green eyes flashing furiously. Castiel caught sight of a sliver of red out of the corner of his eye and, hoping that Charlie and Sam had a plan, attempted to throw the shifted off balance. The shifter growled and sliced another trail down Castiel's face, making him look like he was crying blood.

"Stop moving!" he bellowed. This moment of distraction was enough for Charlie to plunge Sam's knife into the shifter's back. He let out a choked gasp and his grip on Castiel loosened and disappeared as he collapsed bonelessly, the knife sticking out of his back. Dean was immediately by Castiel's side, very gently examining his swollen wrist.

"Dude, you gotta stop letting the bad guys grab you," he joked, lightly poking Castiel's wrist to assess the damage. Castiel let out a pained sound, so Dean immediately let it go.

"The only reason he took me hostage was because I recognised that he wasn't you," Castiel forced out. "Otherwise, I think he would have just killed us after refusing to let us test him."

Dean gave him an odd look.

"How could you tell?" he said. "Even Sammy had trouble back in St Louis with Becky and that shifter."

"I don't think he was being terribly careful," Castiel said as Dean guided him after Sam and Charlie, who were heading back to the Impala. "He wasn't gentle with me and there was a look in his eyes. I'm certain that had he concentrated more on maintaining appearances, he would have fooled me."

Dean rolled his eyes.

"Don't sell yourself short, angel. Now, let's hurry up and get home so I can patch you up and we can have a whole night of healing sex."

"Dean!" Sam complained from ahead. Dean just cackled and tightened his arm around Castiel's shoulders.
