Your Guardian Angel
Castiel had watched as Dean struggled through life. He had been watching over Dean for years, long before he had pulled him out of hell. He wasn't just an archangel; he was assigned to be Dean's guardian angel.
So now here he was watching as Dean, bruised and bloody, collapsed to the ground, due to the demon that he was currently fighting. Sam was yards away dealing with his own fight. He then watched as the demon picked Dean up by the throat choking him. And he could see the blood starting to come out from Dean's mouth. That's when Castiel took action. He flew down and grabbed the demon's hand prying him away from Dean. Dean dropped to the ground as Castiel threw the demon, impaling it on a tree.
Castiel kneeled down and took Dean into his arms. He could feel the life slipping away from him. He tried to heal Dean, but there was just too much. It would take a lot of energy. Dean's body then went still.
Castiel could hear Sam's pounding footsteps as he ran towards them. He handed Dean's lifeless body over to Sam. "I'm sorry…"
Sam looked up at him. "Can you do anything?"
Castiel shook his head. "it would take to much, I don't know if I can…"
Sam broke down as he held his brother's lifeless body, yet again. "Dean…"
Then something clicked inside of Castiel and he looked up at the crying sky. "Forgive me God…."
Castiel placed his hand over Dean's heart and looked up at Sam as he started to glow. "Close your eyes…."
Then there was a huge eruption of light and Castiel was gone. Sam opened his eyes after the blast and heard a gasp. He looked down to see Dean breathing again. Sam broke down and held his brother close, he realized what Castiel had done. Castiel had casted aside everything to bring Dena back to him.
