There are only 4 episodes left before the end of Game of Thrones season 8 and some people think they have already guessed it.
A few days before the release of episode 3 of Game of Thrones season 8, we are already interested in the end because a particular theory could well become reality. According to the member of Reddit zyuko22, the scene in which Beric ignites the young Umber became specter in the middle of a spiral of arms and legs is the key moment that could predict the end of the series. And at the heart of this theory is still the spiral symbol left, a priori, by the Night King or the White Walkers. The same symbol that the Forest Children draw around a tree-heart when creating the first White Walker, the Night King itself.
The Reddit surfer argues that there is a particular tree-heart, the most powerful of all, which would be at the root of all the magic of Westeros. It could be the one on which was attached the man who was turned into a Night King, or another tree-heart that is in the little wood of heart-trees in which the Children of the Forest and the First Men signed their peace treaty to unite against the White Walkers. In any case, this big tree-heart surrounded by a spiral would have a primordial role and it is by igniting it in his heart, as Beric did with the young Umber, that they could get rid of all the spectra.
