Game Of Thrones: 12 Ups And 4 Downs From Season 6

6. Hold The Door

It feels a little weird referring to this as an 'up', because, well, the events here are among the most heartbreaking that the show has ever seen fit to put on screen. At the same time though, it's a major reveal, the answer to a long-standing mystery, and a truly heroic end for one of the show's genuinely good and innocent characters.

The whole build-up to this moment was fantastically gripping and tense, and gave us a devastating look at the White Walkers. Bran, ignoring the Three-Eyed Raven's warnings, goes it alone in a vision, only to be touched by the Night King. That mark means the White Walkers can find him, and also now enter the cave.

After that, it's a thrilling sequence with the Walkers arriving and laying waste to the weirwood tree, the Raven being killed, Meera killing a White Walker, and it all culminates in 'hold the door'.

The intercutting of the scene with Bran and Wylis in the past is superbly done, and the gradual realisation of what is happening, and why Hodor is called Hodor, is absolutely haunting, a scene likely to stay with viewers long beyond the end of the series. If you didn't shed at least a single tear, you're probably a wight.

Furthermore, this show opened up a whole new realm of Game of Thrones and what the show could do: time travel. Bran's actions were responsible of Wylis becoming Hodor before Bran was even born, a causal loop that could be extrapolated into any number of major events throughout Westerosi history.
