This is my concern. I don't understand why there isn't more exposition in the show. Take the Harrenhal scenes; did anyone actually mention they were at Harrenhal? And the Davos / Stannis scene about the finger bones; how on earth is a non-book viewer supposed to understand what's happening there. I mean, it's not that challenging. When everyone approaches Harrenhal, someone says: "That's Harrenhal, it's warped and grizzly because dragons burnt everyone alive there hundreds of years ago." As for Davos, someone could just ask him about the bones. He tells them the story. Bingo. If they couldn't have worked that dialogue into the script, why not simply cut that bit of mishandled characterization out completely? Interestingly, on the UK airing on Sky Atlantic we actually got the HBO 'previously on Game Of Thrones' recap pre-credits, which we've never had before. I wonder if broadcasters, of not producers, are concerned that audiences are (still) watching but in danger of not following what's happened.
