The episode titles came from HBOAsia which uploaded the info to its Game of Thrones episodes page. So they’re not confirmed but they do seem more than likely. And they are “Book Of The Stranger” (6.04) and “The Door” (6.05). As Winter Is Coming points out “The Door” is rather generic and could refer to many doors – literally and figuratively – but better guesses can be made about “Book Of The Stranger”. It seems to refer to a section of the Seven-Pointed Star, the holy text of the Faith of the Seven, with each of the seven sections having a related “book”. The Stranger is the Westerosi god most closely associated with death. All of which indicates a big role for the High Sparrow and the Faith Militant in the episode.
And here are the running times the site has posted:
- Episode 2 “Home”: 54 minutes
- Episode 3 “Oathbreaker”: 53 minutes
- Episode 4: 59 minutes
- Episode 5: 57 minutes
- Episode 6: 52 minutes
- Episode 7: 51 minutes
- Episode 8: 59 minutes
- Episode 9: 60 minutes
Finales tend to be extra long, with the longest episode in the series so far being the season four finale, “The Children,” which was 66 minutes. So expect episode 10 to be over an hour.
