The fans were shocked and angry over a scene in which Sansa Stark was raped on her wedding night by her new husband Ramsay Bolton.
The story plays out more brutally in Martin's book "A Song of Ice and Fire" but in it Ramsay is married to someone else and not Sansa. Martin said there will always be differences into what is in the book and what finally appears on the hit HBO show.
"There have been differences between the novels and the television show since the first episode of season one. And for just as long, I have been talking about the butterfly effect. Small changes lead to larger changes lead to huge changes," Martin said.
The author admitted that it was a demanding task to adapt his "lengthy (extremely) and complex (exceedingly) novels" which come with multiple layers of plots and subplots.
"And yes, more and more, they differ. Two roads diverging in the dark of the woods, I suppose... But all of us are still intending that at the end we will arrive at the same place," Martin concluded.
