Red Wedding

George R.R. Martin has stated that the infamous "Red Wedding" was the hardest chapter for him to write in "A Storm of Swords." He was so emotionally attached to the characters that he actually wrote the rest of the book first, and then that chapter last. David Benioff and D.B. Weiss, upon reading it, declared it was one of the major reasons they decided to option the books for a television series. Their dramatisation differs from the book in a few details. Most notably, Robb's wife is not present at the wedding, nor is she killed. Whether she is pregnant is unknown.
