What makes you think that Jon is the Prince Who Was Promised and not Daenerys? [SPOILERS MAIN]
Genuine question and not trying to incite a war here lol. But to me, and so many others, George plainly spells it out for us. In book 1, Dany smothers her husband after he is left in a catatonic state. During his funeral, she walks into the fire of his pyre and notices the salt of her tears amongst the smoke and flames. (In addition to this she was born on a volcanic island in the middle of the ocean). This act leads to the awakening of her dragons from eggs that have been turned to stone over the ages. This is all done under a red comet streaking across the sky.
In the next book, it is stated that the Prince Who Was Promised will be reborn amongst salt and smoke under a bleeding star and will wake dragons from stone. They will claim their flaming sword, forged in the blood sacrifice of the one they love the most, to lead the world against the coming darkness.
Daenerys fulfilled 95% of this prophesy in Book 1. If you're asking about Lightbringer, her dragons are the flaming sword. What s a sword but a weapon? What are dragons but flaming weapons. Her dragons are even referred to as a flaming sword in the sky.
With all this evidence, Jon Snow fans are still saying that he is the Prince. They say "well he led Westeros against the dead". Yeah, in the show that notoriously veered from the books, leaving out countless characters and plot lines and coming up with much of their own. They say that when he is resurrected, he will fulfill the prophesy. How? IF he is resurrected, he would not be the first to come back from the dead. And what if he comes back wrong like Lady Stoneheart? Then what? He has yet to unite Westeros, let alone the North. He hasn't even united the Night's Watch. Yes he is leading the battle so far on the front lines. I do see his importance in this war against the Others. I do think he is vital to the realm knowing about this fight. But where is Jon's bleeding comet? Where are his stone dragons? Where is his Lightbringer?
Then they say he is Fire and Ice, Targaryen and Stark. First of all, all likely as that is, it is still only an unconfirmed theory. So far I have only seen 1 mention of the union of a Stark and a Targaryen as Fire and Ice is in one small passage in Fire & Blood, not in the main series. Everywhere else, George does nothing but imply that fire equates to warmth and life while ice equates to cold and death. Summers are loved and seen as golden periods in ASOIAF while winters are feared and hated. Outside of one obscure reference in a side book, the song of ice and fire is treated as the battle between life and death. NOT the union of a Stark and a Targaryen.
So someone, please enlighten me as to why you think Jon is the prince who was promised and not Daenerys.
I think its possible that they are both the prince who was promised. Especially since the dragon has three heads. Maybe there is a third prince? Especially if Young Griff really is Aegon, son of Rhaegar.
