Back from Israel to get a rare oil, Castiel tells Dean that it would be his last day on Earth and that he has no plan but sitting quietly until the sun rises.
"Supernatural" gives another preview to its upcoming episode called "Free to be You and Me" through a clip. Over 2 minutes long, it shows Dean discovering that Castiel will soon perform the ritual and after that will vanish like the other angels. Knowing that this would be Castiel's last day on Earth and the angel has no plans but starring blankly in the room, Dean takes him out for booze and women.
"Free to be You and Me" is airing on September 24 on The CW. Dean, intent on stopping the Apocalypse, continues hunting on his own and teams up with Castiel to find the Archangel Raphael, as Castiel believes Raphael knows God's location.
Not sure he trusts himself anymore, Sam decides to give up hunting, but a late-night visitor won't let him off the hook that easily. Adrianne Palicki is back as Sam's old flame Jessica who wants to save Sam from himself.
