For almost 10 years, the Winchester brothers have been entertaining with their unconventional storylines and their good looks. Sam ( Jared Padalecki) and Dean ( Jensen Ackles) have fought against supernatural evil – even in the depths of hell – without getting a scar on their handsome faces. Yet, after all these years, it seems circumstances are getting a bit of a shake- up, with the siblings going out on their own. And to make things even more interesting, they have each acquired a “partner” to help them out. Tonight, Castiel ( Misha Collins) teams with Sam to find evil Gadreel, while Dean and the King of Hell, Crowley ( Mark Sheppard), form an unlikely partnership.
