Bobby was working on his old beat-up truck all day. The fan belt and alternator were broken.
"Stupid piece of..." Bobby cursed but before he could finish he heard yelling.
"BOBBY!!!!!" he could hear the blood curling scream from Cas inside his home. Bobby dropped everything and ran. When Bobby got to the panic room he pieced together what happened. Bobby started to break down right away.
"Cas? are you okay?" Bobby tried to stay calm and help Cas.
"No, i'm covered him his blood...i'm...i'm covered in his blood" Castiel whimpered. Bobby put his hand on Castiel's shoulder and Cas looked up at Bobby. Their faces were painted with sorrow, pain, suffering and many many tears. Bobby managed to get Castiel to let go of Dean. Bobby hugged Cas right away. Now Bobby had Dean's blood on himself and felt broken.
"Bobby...I...I tried to stop him...he looked right into my soul...then he...he..." Castiel sobbed.
"Let's get ya out of the room for a moment before we prep his body" Bobby leads Castiel to the doorway. Castiel looks back at his dead friend. Bobby was so angry at Dean. How could he do this?? Why didn't Dean say anything?? Now Bobby felt the pain of losing both of his sons.
"Here, it helps" Bobby handed Castiel a glass of whiskey. Castiel didn't take his time, he chugged it down and poured himself another. Bobby downed the drink just as fast as Cas.
"Did he leave any note? Or said anything?" Bobby asked.
"I don't know, maybe check his pockets" Bobby suggested. The silence for a brief couple minutes were heavy and unease.
"Bobby...I found them" Castiel gave Bobby the envelope with his name on it. They both opened their letters.
Bobby started to sob. He called me Dad, I lost my sons. Bobby thought to himself. He noticed Cas finished his letter.
"That bastard!!" Castiel screamed out with tears streaming down. He threw the letter on the ground and walked out the house. Bobby let him go to cool off. Bobby picked up the letter Dean wrote for Castiel.
"How could he..." Bobby even started to cry all over again.
Bobby and Cas didn't have the heart to burn Dean's body so they buried him beside Sam in the forest Sam and Dean would play in when they were kids visiting Bobby.
"Stay Cas, we need to help each other. I don't want to lose you too" Bobby asked Castiel to stay with him.
"Bobby, I'm here for you. I will stay" Castiel agreed to staying with Bobby. In all honesty they were watching each other. They both loved Dean and Sam so much. They didn't expect Dean to do this though.
