Castiel stood silent as he watched from afar. Sam held the demon knife tightly at the demons throat, but was not killing it. Castiel wondered why Sam was hesitating. Then he saw Dean, knife held to his throat, standing a good distance from Sam and his hostage demon. They were in a stand off. Castiel had to think fast. He had no angel abilities, no power, and no grace. He had to think fast. Castiel thought of a plan, but the plan was very risky. Then, Castiel pulled out his angel blade and was able to sneak up closer to where he was behind Sam and his hostage demon. Castiel then thought of what to do next. He would get into position where he would throw his angel blade and, hopefully, stab the demon holding Dean. After moments of listening to Sam and the demon argue over who would kill who first, Castiel was in perfect position to throw his angel blade. Castiel's eyes met Deans...and Dean nodded...Castiel knew he must know of his plan to handle the situation. Then, he aimed with hid angel blade...right at the demons head. He pulled back, and then with all his might threw the blade at the demon holding Dean. The blade shot right between the eyes of the demon. The demon fell. The angel blade stuck in its forehead. Castiel glanced and saw that Sam had killed the demon he had been holding. Castiel turned back to see Dean barely standing, holding his left side with his hands; blood oozing around his fingers. Castiel ran over to Dean's side, and gently caught Dean from hitting the ground. "Heal me, Cas, god dammit this really hurts." Dean coughed blood. Castiel stared into Dean's eyes. "I cannot." Castiel buried his head in his hands. "I have no grace, no power Dean. I cannot heal you." "Cas," Dean breathed deep. "Watch over Sam, you hear?" Castiel couldn't believe what was happening. He was losing Dean right before his eyes and he could do nothing about it. Castiel gently grabbed Dean's hand. "I will watch over Sam, Dean." Castiel leaned down to whisper into Dean's ear. "I will find you." Castiel felt the air leave Dean's body. Dean was dead.
