10 Major Game Of Thrones Deaths You Didn't Give A Sh*t About
2. The White Walker
When Samwell Tarly managed to slay a White Walker while protecting Gilly and her child, it was a great moment for Ser Piggy's character development. Until this point, Tarly had been the most craven of all characters on the Wall, and his encounter with the White Walker was a brave act of heroism. However, many watchers weren't aware of just how important the death of the White Walker was.
This stems mainly from the confusion between the Wights and the White Walkers. While the Wights have been killed on-screen numerous times since the first season, this is the first account of a White Walker being successfully killed in thousands of years. In slaying the White Walker, Samwell Tarly discovered that the creatures are highly vulnerable to blades made from dragonglass.
