Angel With a Shotgun

Kayla is an Angel of the Lord and has always loved the way humans worked. One day she see's Lucifer hurting and torturing Sam Winchester and come's down to Earth to help him even though the other Angels told her not to. What will happen when she becomes closer to Sam like Castiel is with Dean?

I sadly do not own Supernatural and the characters, but I do own Kayla and some other characters. Enjoy :)
