This isn’t the first time an actor’s role in the show has been rumored to be put on hold due to a lack of book material. The show’s executive producers admitted that both Bran and Hodor won’t be appearing in the upcoming season, as the show has caught up to their timeline in A Dance With Dragons. There is still plenty of Arya material from the books to cover, but from Maisie’s comments it sounds like the show is catching up far more quickly than anticipated.
The next installment in the series, The Winds of Winter, has yet to confirm a release date, but author George R.R. Martin has taken a step down from the show to focus on finishing the novel. ~Kelly Townsend
