What It's About: Two brothers driving across the country in a black muscle car, saving people, hunting things…the family business. When things go bump in the night, Sam (Jared Padalecki) and Dean (Jensen Ackles) are there to take them out. But after 10 seasons, they've both died, gone to hell, heaven, purgatory, and every other dimension you could think of, and they've got the scars—both physical and emotional and mental—to prove it.
Words to Know: "King of Hell" = the crossroads demon Crowley worked his way up the corporate ladder to become the ruler of all demons. "Mark of Cain" = Dean received the Mark from Cain himself in order to kill the big bad Abaddon last season, but it's affecting him in major ways, making him a demon earlier this season and urging him to kill now that he's back to being a human. "Men of Letters" = Sam and Dean's paternal family come from a long line of scholars who studied and researched all kinds of supernatural phenomenon. They all died out, leaving the bunker filled with records and supernatural objects to Sam and Dean, finally giving them a home base. "Destiel" = the shipper name rabid fans have given the bond between Dean and his angel friend Castiel—though some fans believe the two men are actually in love.
Thing to Say: "I miss the case-of-the-week format from the earlier seasons!" or "I love how this season is telling more personal stories about Sam, Dean, Crowley and Castiel." or "I can't wait for Cain to return to finally help Dean out with the Mark!"
Episode to Watch: "Fan Fiction," or the 200th episode of the CW series. This meta look at the entire series is a great catch up on all the fan-favorite characters and stories in one simple episode. Plus, it's all about one of the longest and greatest running gags of the show: the prophet Chuck Shirley's books (the Winchester Gospels) about the brothers! Many fans believe Chuck is actually God, and thanks to the final scene of this episode, we're believers, too!
