There is a guy who says nothing but Hodor. It turns out that this is because he once had to tell people to "hold the door". The Blondie Lady is called Daenerys something-or-other. She is the mother of dragons; this may or may not be literal but she does have pet CGI dragons who burn people up for her. She is known as the Khaleesi. She acquires and then frees a CGI slave army who choose to freely follow her because what else are they going to do?
There is a brother and sister who are shagging each other. They tip a young lad (close relative?) out a window when he catches them at it. The young lad mysteriously survives. Meanwhile the brother and sister have a son (passed off as son of the sister's husband) who becomes the Mad King Joffrey, who is mad and bad. He is eventually killed.
