units Stark Arya
Benioff and Weiss sometimes assigned characters to particular writers; for example, Cogman was assigned to Arya Stark for the fourth season. The writers spent several weeks writing a character outline, including what material from the novels to use and the overarching themes. After these individual outlines were completed, they spent another two to three weeks discussing each main character's individual arc and arranging them episode by episode. A detailed outline was created, with each of the writers working on part of it to create a script for each episode. Cogman, who wrote two episodes for the fifth season, took a month and a half to complete both scripts. They were then read by Benioff and Weiss, who made notes, and parts of the script were rewritten. All ten episodes were written before filming began since they were shot out of order by two units in different countries. Benioff and Weiss wrote their episodes together; one wrote the first half of the script with the other writing the second half. They then passed the drafts back and forth to make notes and do rewrites.
