"The game of Thrones" has long ended, but the fans of the series again and again find the reasons to be upset due to missed plot opportunities. This time, the object of attention was the "Battle of Winterfelle", in which a very weighty problem was discovered.
To the dark, reigning throughout the episode, fans have come for a long time ago, but by the fact that no one thought to use the dragon glass to create weapons, it seems to be indignant for the first time. One of the users Reddit noticed that at least this substance was found in the seventh season, for some reason, neither John Snow, nor Daeneris occurred to make up the arms from it, which would help to deal with white walkers without problems, and with By the king of the night, and even with Vierion.
And this indignation looks logical, because there were no objective reasons why John and his allies could not prepare before the battle as many tips as possible. Surely the famous ability to make Gengri's weapon with such work would cope with such a work, and if for some reason it was impossible, it was worth clearly called the reason.
It turns out that the entire mission of John, when he went to the meeting with Daineris in the seventh season, did not help the soldiers of Winterfella. So the story with dragon glass can be considered another lost possibility of the "Game of Thrones".
