Supernatural's last pre-hiatus episode airs on the CW this Thursday, November 20, 9/8c. The TV Addict has a first look at the episode, titled "Heaven and Hell." Then it's time for the show's usual winter break, while fans of the horror drama, which is notorious for going into hiatus with a cliffhanger or at least game-changing revelations, are left to speculate, discuss, and wait. The show will return on January 15, 2009.

The January 30 episode, TV Guide reports, will be titled "Afterschool Special" (in keeping with Season 4's theme of using titles like "Are You There God, It's Me Dean Winchester" and "I Know What You Did Last Summer"). Sam (Jared Padalecki) and Dean Winchester (Jensen Ackles) look into a haunting at their old high school. We get flashbacks to the Winchester brothers as teenagers. Sam runs into trouble with some bullies, older brother Dean watches his back – as he always has.

Colin Ford, who provided a spot-on young Sam Winchester in Season 3's "A Very Supernatural Christmas," will reprise his role. Brock Kelly, who has appeared on Days of Our Lives (where Jensen Ackles was once Eric Brady), will portray teenaged Dean.
