14 Times MVP Samwell Tarly Literally Changed the Course of Game of Thrones

Sam meets Gilly in the second season when the Night's Watch stop at Craster's Keep during an expedition beyond the Wall. We learn that Craster is a wilding who marries his daughters and sacrifices the sons borne of these illegitimate unions to the White Walkers. Among the women is Gilly (who we later learn is pregnant with a boy). Sam is heartbroken by her mistreatment and vows to rescue her when the ranging party returns.
