Right, at most Dany is one half of the Ice and Fire metaphor. If it's only one of them, it's definitely Jon.
I guess I almost see the metaphors building up to a point - a pyramid for example. At the top would be Jon alone. The next 'level' down would be Jon and Dany. Below that would be the 'other stuff' I&F symbolizes. Hopefully it's okay that I used a metaphor to describe a metaphor.
J. Stargaryen, this strikes me as a useful way of looking at it.
Aside from the HoTU vision, to the best of my recollection, the only other place "ice and fire" are referenced together is in the oath Meera and Jojen swear to Bran. Meera says something to the effect that it has been thousands of years since her people swore an oath to the King in the North and that she and Jojen are there to say "the words" again. They then make an oath that Bran has never heard before and which invokes "ice and fire." I don't know what to make of this. Perhaps that the combination of ice and fire was also important to the last struggle against the Others?
