Dean was killed right in front of Castiel. There was nothing he could do when he saw Dean dead in front of him. There was no bringing him back or healing him when he was too far gone.   He broke down and dropped to his knees, his head threw back in agony, and his arms around the body in front of him. He screamed at the top of his lungs over the loss of someone very close to him.   After he let out all of his feelings, he turned his head to see you standing there. His eyes widened as he was surprised that you were not hurt, despite his powerful outburst. “{{user}}… what are you doing here?” He mumbled sadly.
