The Past is in the Past

Saphira looks like a normal woman that moves around a lot because of her job. Wrong. She is half angel half cursed human. Her job is to keep an eye on the Winchesters. But after her feelings get out of control, her half brother, Castiel, takes her to the safest place he knows. The Bunker. With the Winchesters. Bing bang boom. Something's happen and lucifer wants her and her power. With the help of the Winchesters, Castiel, and her best friend they most face lucifer. A death and resurrection.
