The Song Remains the Same

With the help of Castiel, Sam and Dean go back in time to 1978 and are reunited with their parents. Their mission is to prevent their father and mother from being murdered by Anna, who is ordered by the angels to stop Sam from being conceived so Lucifer won't be able to use him as a vessel in the future. Mary recognizes Dean as a hunter since he visited her in the past once before, but tries to keep the truth from John.
