9. Benjen Stark
Its been a long, long time since we saw Benjen Stark, the younger brother of Brandon and Eddard who was the First Ranger of the Nights Watch and was responsible for the recruitment of his brothers bastard child Jon Snow before his disappearance on a ranging. Though the two men who disappeared alongside him, Othor and Jafer Flowers, reappeared as wights (reanimated corpses), Benjen has not since appeared alive, dead or undead, meaning that his fate remains uncertain. A popular belief amongst fans is that Benjen is Coldhands, the undead man dressed in the colours of the Nights Watch that provided assistance to both Samwell Tarly and Bran Stark. This theory is seemingly disproved, however, by the fact that Coldhands is stated to have been killed long ago, whilst Benjen has only been missing for a few years (and would surely be recognised by his nephew Bran anyway). Nobody can be confirmed dead until there is a body, however, so dont be too surprised to see Ned Starks younger brother show up in some capacity once again.
