Fire Cannot Kill a Dragon, a new Game of Thrones oral history book reveals some disturbing details about the once-popular show’s legacy regarding sexual violence against women.

According to the book, author George RR Martin was not consulted about the change in a consensual sex scene which was changed into one that showed sexual violence and assault.

Insider reports that David Benioff and DB Weiss never discussed details about Daenerys and Khal Drogo’s wedding night with him. “It made it worse, not better,” Martin said. The sex scene in the book, A Song of Ice and Fire is consensual whereas, in the show, Daenerys gets violated by Khal Drogo.

“Why did the wedding scene change from the consensual seduction scene … to the brutal rape of Emilia Clarke? We never discussed it. It made it worse, not better,” Martin said in the book.

“Here’s a girl who is absolutely terrified of this barbarian warlord she’s being married off to, it’s the last thing in the world she wants, yet somehow by the end of this wedding night, she seems to be in a completely joyful sexual relationship with him. It didn’t entirely work for us,” Benioff said, in defense.
