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

Near the end of the second season, the Night's Watch continue their march beyond the Wall toward the Fist of the First Men, where Sam finds a collection of Dragonglass weapons. Not long after, a group of White Walkers attack their group. Sam's lack of athleticism leads to him tripping in the snow and being left behind when an eerie mist rolls in and the undead approach. A walker riding a dead horse notices Sam but ignores him and orders the wights toward the Fist, where other members of the brotherhood hide.
