Sunday night's episode of the HBO show "Game of Thrones" was a shock to viewers of the show, but not to readers of the books.

There was some serious carnage and major characters were violently killed off and judging by this video of casual fans of the tv series, it came as a total surprise.

Watch the reactions of differnet people watching, it reminds me of when "The Sopranos" ended with a black screen and I thought the cable went out.

The season finale of "Game of Thrones" airs this Sunday on HBO.
