Game of Thrones Season 8: What could be the end “sweet-bitter” promised by George RR Martin?

A few months before the release of the season 7 of Game of Thrones, one wonders about how the series could end.
The wait is long, very long until the return of Jon Snow, Arya Stark and others and melty continues to help you wait until this summer. After listening to 3 major plots that will probably not be seen until the end of Game of Thrones’ season 8 , we’re just back at the end of the saga and wondering how all this could end. Some time ago, author George RR Martin stated that A Song of Ice and Fire would end in a “bittersweet” or bitter sweet and the possibilities to match this description are many . We propose you a possible end for Game of Thrones knowing that it is only speculation and that it is also possible that the end of the series and the end of the books are not quite identical. As usual, Reddit members like to find theories and this one is far from being uninteresting.
An Internet user points out that in addition to R’hllor, Melisandre has already spoken of his supreme enemy, the “Great Other” god of cold and darkness. She describes him as “a wooden face, a white body, a thousand red eyes and a boy with a wolf head at his side” that she assumes to be the Great Other champion, just as she assumed that Stannis was The champion of the Lord of Light. Could it be that Bran Stark, who by his connection with the Sacred Wood and his wolf, although he is dead, could be the champion of the god of darkness? In this case and if Jon is the champion of R’hllor, we can expect a confrontation between Jon and Bran at the end of the series at the end of which good or bad would prevail – if We define things in a Manichean way.
Obviously this supposes several things, starting with a correct interpretation of the visions of Melisandre – area in which it has not shone so far. After having mistaken Stannis Baratheon, there is no evidence that she is not once again making a mistake since it is also possible that Daenerys is the champion of R’hllor . But it must be admitted that a fight between the two half-brothers / cousins, being part of the family that introduced us to the series, would constitute a bittersweet end. Anyway we still have all the time before us to speculate on the end of the series and it is not the possibilities that are missing. While waiting to know what will happen in the last episodes, we wondered if Daenerys would die to make a prophecy in Game of Thrones’ season 8. And you what do you think ?
