On Sunday night's episode Breaker of the Chains, Jamie raped his grieving sister Cersei over their son Joffrey's dead body, even as she was constantly trying to fight off his advances.

The disturbing rape scene from HBO's blockbuster fantasy drama triggered a vigorous debate among fans and critics alike and many have said it was 'gross' to feature it on television.

The season 3 of Game of Thrones has seriously tried to transform the once villain Jaime Lannister into a hero but show director Alex Graves ruined all those efforts with the controversial rape scene in the latest episode.

Graves later explained the 'forced sex' scene in an interview to Hollywood Reporter:

"Well, it becomes consensual by the end, because anything for them ultimately results in a turn-on, especially a power struggle.

"He is their first born. He is their sin. He is their lust, and their love, their everything, if he's gone, what's going to happen?" he added.

While many critics slammed the show director for tarnishing Jamie's character all over again and glorifying rape on television, entertainment site vulture.com explained why it was rape and not consensual as the director claims.

"Cersei says "no" and "don't" repeatedly, begs Jaime to stop several times, and the scene ends on weeping "it isn't right," while Jaime grunts "I don't care," the report said.

Meanwhile, author of the Game of Thrones novels George R.R. Martin distanced himself from the entire controversy stating that he was never a part of the 'rape scene' discussion.

"In the novels, Jaime is not present at Joffrey's death, and indeed, Cersei has been fearful that he is dead himself, that she has lost both the son and the father/ lover/ brother. And then suddenly Jaime is there before her," Martin explained in his blog.

"The whole dynamic is different in the show, where Jaime has been back for weeks at the least, maybe longer, and he and Cersei have been in each other's company on numerous occasions, often quarrelling.

"The setting is the same, but neither character is in the same place as in the books, which may be why Dan & David played the sept out differently. But that's just my surmise; we never discussed this scene, to the best of my recollection."

Meanwhile, fans expressed their displeasure on the 'Jamie rapes Cersei' scene through Twitter calling it unnerving and horrible. Check out some of the fan tweets here.
