Benjen Stark (Joseph Mawle) left fans wondering about the lost Stark's fate when, at the end of Season 7, he sacrificed his life in order to save Jon Snow (Kit Harrington). But did he really sacrifice himself, though? We did see him being grabbed by the flock of White Walkers as he let Jon escape with his horse while he stood firm trying to divert their attention from him. However, chances are that Benjen Stark, the youngest brother of Ned Stark (Sean Bean), is not yet done with his story and we might just see him return for more in Season 8.
Benjen has time and again acted like the hidden guardian of the Stark children, coming more than often to their rescue. However, he is one character who seemed to have been lost from the main events for the longest time.
Considering his experience beyond The Wall, it seems that he knows things which nobody else does. After leaving Jon with the brothers on The Wall, Benjen left to find his missing mates who were killed in the very first episode of Season 1. However, later on, we come to know that he was attacked by the White Walkers but was saved by the Children of the Forest when they resurrected him with the help of a dragon glass.
Benjen reveals this information to Bran (Isaac Hempstead Wight) towards the end of Season 6 when he rescues him and Meera (Ellie Kendrick) from the White Walkers.
Benjen is unable to go on the other side of The Wall since he is technically undead and the curse prevents him from crossing The Wall. He appears once again in Season 7 and helps Jon Snow escape from the hands of the Night King and his army of the undead. While the scene almost portrays that Benjen is being killed, considering that the Children of the Forest actually prevented him from turning into a White Walker, he is technically half White Walker and half man. Could this mean that Benjen has an important role to play in the upcoming season?
Chances are that Benjen might be the one who comes once again to rescue the Stark children as they stand up against the Night King in Season 8. It is unlikely that he will turn into a White Walker since he is already protected with Dragon Glass. He might just help them hold back the Night King a little while longer, considering that the dead have a fully grown dragon on their side now. However, it is not yet confirmed if Benjen is returning and hopefully when 'Game of Thrones' Season 8 returns on April 14, we will get to know more about the wandering Stark.
