The Halloween fever is taking over the next episode of "Supernatural". Sam and Dean will race to find a witch named Tracy who is sacrificing human lives in order to summon a dangerous demon while Castiel returns with Uriel, a specialist angel who wants to smite the town.
Sam disobeys orders from Uriel to not interfere with certain demons who attack both the brothers and the town, so Uriel threatens their lives. The episode will be titled "It's The Great Pumpkin, Sam Winchester" and aired on The CW October 30 at 9/8c.
The show has taken in a new villain who will appear on the November 13 episode. Mark Rolston, known for his icy look in series like "Aliens", "Cold Case" and others, will take a recurring role as Alastair, the latest demon that becomes the brothers' worst nightmare.
