Sam trudged into the bunker, boots heavy, heart infinitely heavier. Dean was gone. He told him it was okay for him to go but it wasn't. It was what he needed to hear though.
Sam couldn't bear to leave him in that barn. When Dean went silent, motionless, Sam gently pulled him from the rebar and carried him to the Impala. He was still there. It was his happy place. Sam would give him the hunter's funeral they had given so many others. Later. For now, Dean could sleep in the Impala one final time.
When Sam neared the door of the kitchen, his mind focused solely on retrieving the half-empty whiskey bottle Dean left behind, he paused. He could hear the soft sounds of someone pacing. Sam's heart thudded as he quietly pulled his gun from where it had been tucked in the back of his jeans. It had to be a threat. There was no one left. Cas was gone. Jack was gone. Dean was...
Sam crept around the doorway, lowered his gun and froze as he caught sight of the familiar trench-coated figure.
This cannot be happening.
Cas turned to face Sam with a nervous smile on his face that quickly fell when he observed Sam. Red eyes, blotchy cheeks, hunched posture, the epitome of despondency.
"Sam?" The question in his tone was clear.
"Cas," Sam choked out as tears he couldn't believe were left started to form and run down his face.
Cas walked slowly over to Sam and placed a hand on his shoulder. His face was full of concern but there was the tiniest glimmer of hope that would soon be extinguished.
All Sam could do was shake his head as the tears started falling faster and his breathing became shallow.
And there it goes. The hope.
Cas dropped his arm and stepped back.
Sam closed his eyes. He couldn't watch this.
Sam flinched and peeled his eyes back open when he heard a thump. Cas was on his knees, shaking, with his face in his hands. He was silent for a few moments until the unmistakable sound of a sob escaped.
They wept together, Sam frozen on his feet and Cas slumped on his knees, for several minutes.
Slowly, Cas pulled his hands from his face and the look of despair he had was so visceral Sam wanted to look away. But he couldn't.
Cas opened and closed his mouth a few times as if trying to form words that he couldn't manage to choke out. Eventually, a barely audible sound trickled from his lips.
Sam closed his eyes and nodded.
