The numbers are in for the initial viewing for this weeks episode of Game of Thrones. "Sons of the Harpy" had a total of 6.82 million viewers for the first airing of the episode. This episode was just slightly higher than last weeks episode, "The House of Black and White", which had 6.71 million viewers for the initial airing.
Although "Sons of the Harpy" saw a slight rise from the previous week, the shows viewership has been quite stagnant since the season 5 premiere. I think next weeks episode, "Kill the Boy", will see a dramatic rise in viewership - being the first non-leaked episode of the season. If episode 5 does as I expect it to, then I think we will see a consistent rise in viewership for the rest of the season.
