Castiel is back and he informs the Winchester brothers that lethal weapons have been stolen from heaven.
The "Supernatural" trio are back. Sam and Dean call Castiel for help when they investigate a case about several dead police officers who seem to have been killed by the plagues of Egypt.
Castiel confirms the staff of Moses was used to kill the cops and tells Sam and Dean that Heaven is in a state of chaos and God's weapons have been stolen. The three head off to find the thief and come face to face with an old enemy.
"The Third Man" airs October 8 at The CW. If the preview is to be believed, then this episode will also be the one where Jared Padalecki takes off his top and works out on a bar.
The sixth season of "Supernatural" debuted well on September 24 with 2.8 million viewers which is slightly better than season 5's 2.6 million.
