 The episode was written by the showrunners David Benioff and D. B. Weiss , based on the original novel by George R. R. Martin . The chapters included in " You Win or You Die " are 46 , 48 @-@ 50 , and 55 ( Eddard XII , Eddard XIII , Jon VI , Eddard XIV , and Daenerys VI ) , making it the episode that includes fewest chapters of the source novel in the entire first season . Among the scenes created specifically for the show were a meeting between Tywin and Jaime Lannister ( as Lord Tywin is field dressing a stag ) and a " training " session between Littlefinger and two new female recruits for one of his brothels .
