With George RR Martin’s last two books in “A Song of Ice and Fire” still on their way, fans are making their own conclusions about how HBO’s “Game of Thrones” will end. In the most shocking plot twist, pundits believe that the Night King is actually Bran Stark. Here are some plausible pieces of evidence that fans have picked up over the last six seasons.

An accidental warging

Bran has the capability to warg and it was amplified by his time learning with the Three Eyed Raven. More than observing, Bran has the capability to travel through time and be in the moment.

During a White Walker attack, he sought help from Wylis, and he met Hodor in that famous and heartbreaking “Hold the Door” scene. When he comes face to face with the Night King, he was even touched by the leader of the White Walkers, proving that he was part of the scene and not an invisible bystander.

When he was starting out with his time traveling, it can be recalled that the Three Eyed Raven advised him not to get stuck in the past, knowing the strength of his abilities. However, with so many answers living in the past, it is possible that Bran’s curiosity may have gotten the best of him. Ultimately, this may have led to the creation of the biggest threat Westeros has ever seen, reported PopSugar.

Reddit user TurmOil26 suggested that in realizing the extent of his powers, Bran may have tried to travel back in time before the Children of the Forest created the White Walkers. He could have warged into one of the First Men and accidentally became the Night King himself.

A connection with Jon

Fans have often wondered why, in all of his encounters with Jon Snow, the Night King seemed to have a moment with The King of the North.

Theories suggest that since Bran is the only person to know about Jon’s true parentage, he also senses a bigger role he has in the wars to come. Perhaps the Night King sensed that Jon is the Prince that was Promised?

A slip-up by the Children of the Forest

In a scene in Season 5, Leaf tells the story of the White Walkers to Bran and makes a telling statement.

"We needed to defend ourselves... from you." Leaf later amends it to "from men," to make the statement more general. However, fans believe that this was a significant slip-up that the Children of the Forest knew Bran from way before he came to the cave, a Bustle report stated.

There may still be loopholes in the theories but with these reasonings, but they sound plausible enough as a George RR Martin plot twist. Fans of the renowned author wouldn’t put it past him to make a protagonist turn into the show’s biggest villain. For now, there are two episodes left for “Game of Thrones” Season 7 and a final season remaining to answer all of the questions. It is likely to come sooner than Martin’s last book “A Dream of Spring.”
