Long may he reign!

The King of Hell will be sitting comfortably on his throne when Supernatural returns for its tenth season: Mark Sheppard, the man behind fan-favorite Crowley, has officially been added as a series regular for the year. We don’t know how many episodes he will appear in at this point, but considering Dean’s hellish situation, we’d bet that Crowley’s involvement will be key.
