In the “Ice and Fire” novels by George R. R. Martin, Coldhands is really a figure that's undergone by Samwell Tarly and later by Bran Stark, Hodor, Meera and Jojen Reed. In the 3rd season, Sam has recently came back from beyond the Wall and met Bran however the series has yet to introduce Coldhands and fans have already been wondering if that he was taken off the HBO series.
Coldhands acts as helpful information to Bran and his journey to get the three-eyed raven, referred to as the three-eyed crow in the novels, beyond the Wall. There may be different ways to possess Bran reach the final greenseer, such as for example introducing the kids of the Forest before the group achieving the cave of the three-eyed raven so it’s unclear if the type by the end of the brand new trailer is Coldhands or simply a White Walker.
The trailer also provides a glance at Stannis Baratheon, Shae and Theon Greyjoy. The Red Viper and his duel with Ser Gregor Clegane get a bit more screen time aswell. Cersei sometimes appears in a court setting, plainly testifying against Tyrion Lannister following a death of Joffrey Lannister.
