Let it be
Dean Winchester's life changed forever the night a demon appeared in his brother's nursery and killed his father.
As a hunter Mary is determined to protect her sons from the evil she has run from her whole life - the same evil that took John. But Dean also trusts his protection to the angel in a trench coat he talks to in his dreams. Through years of tribulation and uncertainty, the Winchesters (plus a corgi that might be magic and an angel that may not be real) must fight monsters, demons, and even fate itself to survive as a family.
Or: The one where Mary lives, Cas is there, and nothing and everything changes.
