Hours later, Castiel found him like this. Hunched over in agony, head bowed, gasping and sobbing as he rocked back and forth in the throes of deepest grief and remorse.
Hovering awkwardly in the doorway, Castiel hesitated, momentarily stunned. Sam hadn't noticed him yet, so wrapped up in torturous pain he was oblivious to his surroundings. Castiel stared at Sam, horrified and transfixed by the man's intense suffering.
