Dean wiped his brow as he took a deep breath and let the shovel rest against the dirt on the ground. The field was quiet and empty, the only sound was the wind blowing through the trees around the field he was standing in. Baby was playing a tune in the distance. He didn't think much of the song until the words hit him a little too hard, and as he stood over the hole in the ground, the body in the hole still and motionless, he wept.
"It was not your fault, but mine. I really fucked it up this time..."
Dean dropped to his knees, the tears falling harder each time the chorus played that line. The salt and gasoline sat beside him untouched and ready to be poured over the grave.
Dean's cries seemed to wave him over to the point where he didn't want to move, didn't want to pour the salt and the holy oil over the grave. He was holding in his emotions as he placed the body gently into the trunk of the impala and closed her up. He was holding in his emotions as he drove to an empty field, his heart was heavy and blue.
He knew it was time to do this deed and he felt so terrible about this.
Dean grabbed the salt and slowly poured it over the body and took a deep breath. The next part was the holy oil, and he didn't want to do it, he tried so hard to pour it into the grave. The last line of the song began, and just as he grabbed his matches, he felt a presence and he turned around.
"Dean."
"I'm sorry Kevin. I know I fucked up."
"Don't worry. I kinda knew this would happen sooner or later."
"I just feel so shitty about putting you through all this crap, you know. Being a family is harder in this business."
"I know Dean. You gotta stop being so hard on yourself and let stuff like this go. It's tearing you apart inside, man. Go fix Sam and enjoy doing what you love doing."
Dean was still crying as he lit the match he held in his hand. "Go ahead, Dean. Going out like a hunter is the best way, am I right?"
"Say hello to your mom for me." And with that last word, Dean threw the lit match into the grave and watched the flames engulf Kevin's spirit and disappear into the air.
Dean took a deep breath as he waited for the fire in the grave to die down. Grabbing a cold beer from the cooler in Baby's backseat really makes him feel better in a way.
As he was about to open his beer, he thought "Cas where are you man?"
He heard a flutter of wings and he turned his head to see a familiar figure leaning against Baby and an extra case of beers in hand.
"Hello Dean." Dean took ahold of the all too comforting trenchcoat and pulled the angel into a hug and wept into his shoulder. Castiel knew he was feeling alone, with Kevin the prophet now gone and Sam now gone and Gadreel taking ahold of his body, Castiel was the only one who hadn't left him.
"I don't know what to do, Cas."
"It's okay, Dean. I'm here for you. We'll get through this together, right?" Dean let go of Cas to see the ocean blue eyes pool around and around, putting him into a happier mood.
"Thanks, Cas."
After the fire died down, Dean placed the dirt he dug back and grabbed the makeshift cross he created at the bunker, the initials "K.T." carved into the wood and peirced it into the dirt next to the grave.
Dean took one last look at the dirt and gave a soulful look before sliding into the impala and driving away, Cas riding shotgun.
Castiel turned the radio on before Dean had the chance, and he smiled as he knew the song he picked was perfect.
"Carry on my wayward son..."
