A brief preview to episode 4.03 of "Supernatural" has been unearthed. This upcoming episode is called "In the Beginning" and will be aired next Thursday, October 2, at 9:00 P.M. on The CW network. It reveals that Dean is faced with the fact that if he alters the future, his hard works of saving people will all vanish into nothing.
In the new episode, Dean is thrown back to the year of 1973, and to much of his surprise, he finds himself landing in Lawrence, Kansas. Unsure why he is sent back to the time, he soon enjoys the experience after he bumps into young John Winchester and Mary who have just fallen in love. In this past era, he also meets his newly-found grandfather, who may be hiding a secret that is key to his and his brother dilemma.
Teaming up Jensen Ackles and Jared Padalecki as the Winchester brothers, "Supernatural" follows Dean and Sam who travel across the country to investigate paranormal events and other unexplained occurrences which often force them to combat supernatural creatures. The Eric Kripke's TV series falls in its fourth season starting on September 18.
