Bran Stark is in grave danger on HBO’s “Game of Thrones.” In Season 6, episode 5, he lost both the Three-Eyed Raven and Hodor after narrowly escaping from the cave. Meera is dragging Bran through the snow, and the Night’s King will continue to pursue them. But the two might have help from an old family friend in episode 6.

One Reddit user suggests that Benjen Stark (Joseph Mawle) will return in episode 6 to save Bran (Isaac Hempstead Wright) and Meera (Ellie Kendrick). Publicized by Bustle, the theory suggests there is evidence pointing to the return of Benjen. In the Season 6 trailer, a man is shown on a horse fighting off wights with fire. The last time Benjen was seen was when he left on horseback to go on patrol beyond the Wall in Season 1. But he never returned to Castle Black, and many believe he was killed.

For those who don’t remember, Benjen is the younger brother of Ned Stark (Sean Bean) and was first ranger of the Night’s Watch. He played a part in recruiting Jon Snow (Kit Harington) to join the Night’s Watch and has served as his role model in a way. A younger version of Benjen appeared in Season 6 in one of Bran’s flashbacks where he saw Ned teaching his little brother how to fight.

While some believe Benjen’s return is imminent, others think Coldhands, a character from George R.R. Martin’s “A Song of Ice and Fire,” will debut on the show. Coldhands is a mysterious character who dresses in clothes of the Night’s Watch and rides on a great elk, but never shows his face. He serves the Three-Eyed Crow in the books and was the one who took Bran and Meera to the cave. He also helped save Samwell Tarly from wights in the novels. Some believe that Coldhands is actually Benjen, but it has not yet been revealed.

In the episode 6 promo video, Meera and Bran were still on the run from the White Walkers. Hodor (Kristian Nairn) did his best to hold the door closed on the White Walkers, but they eventually started to break through. Hodor gave his life to protect Bran, and now all Bran has is Meera. Wights are closing in on them in the promo video and Meera is heard saying “I’m so sorry,” but help could be on the way.

“Game of Thrones” Season 6, episode 6, airs Sunday, May 29, on HBO at 9 p.m. EDT.
