VIDEO: Sneak Peek at SUPERNATURAL's Return

When Supernatural returns with all new episodes on Feb. 25, no one is prepared for the un-shore.

Sam (Jared Padalecki) and Dean (Jensen Ackles) have spent the last eight years battling the things that go bump in the night. Over the years, and occasionally alongside the fallen angel Castiel (Misha Collins), and the King of Hell, Crowley (Mark A. Sheppard), the Winchesters have straddled the line between good and evil.
