 " Baelor " marks the first appearance of the German actress Sibel Kekilli , in the role of the prostitute Shae . Executive producer George R. R. Martin commented that she was extraordinary in her audition , in which she read the scene where Shae meets Tyrion in a tent the night before the battle of the Green Fork . According to Martin , " a lot of beautiful young women read for Shae . [ ... ] But there 's another dimension to Shae as well . She 's not as practiced and hardened at this as a more seasoned pro . There 's still a girl next door quality to her , a sense of vulnerability , playfulness , and , yes , innocence . [ ... ] All of our Shaes were hot as hell . But only a handful of them captured that other quality , maybe three out of twenty , and Sibel was the standout . [ ... ] Watching those auditions , any red @-@ blooded male would want to take every one of our Shae candidates to bed . But Sibel made you fall in love with her as well . "
