Decapitation of... who?

Castiel’s POV

“Who the hell are you!” A huge, very well muscled guy demanded. I recognized him as a vampire.

“Castiel.” I replied calmly. “I am an angel of the lord.”

The big guy scoffed.

“Who the hell are you?” I shot back.

“Vampires,” Dean said, really casually.

My eyes widened, as I immediately thought of the worst scenario. 

“They captured you! We got to kill them!”

Dean laughed a little. So did the vampires. 

“I’d like to see you try,” a blonde-haired vampire, who stood beside the muscly one snickered.

I raised my eyebrows, smiling, “I’d like you to see my true form.”

Dean put a hand on my arm. “Cas.” He warned.

Suddenly I heard a loud buzzing sound in my head. “Castiel,” I heard, “ Castiel you son of a bitch. I kinda need you so get your feathery arse down here.”

“Sam.” I whispered.

“What?” Dean demanded.

“He summoned me,” I whispered.

“This is awkward,” Dean muttered. Then he shook himself. “Where is he!”

“I don’t know Dean. I really don’t know.” I said sadly.

“Go find him then.” Dean commanded. “And come back to tell me where he is.”

 I found myself in a room that looked like a warehouse. Sam was in front of me, looking worse-for-wear. His lip was cut and bloody, his arm, broken, hung at an awkward angle. He was tied to a chair, but was not gagged.

“Cas! Behind you!” He exclaimed in a husky voice. I swung around. Another vampire had the Colt gun pointed at me. “I’ll be back,” I whispered to Sam. And disappeared.
