In contrast to Dany’s struggle against Aegon VI or Cersei or the Greyjoys, I feel like her conflict with Stannis will be more metaphorical in nature. If Stannis’ plot goes as I expect, finding out that his Aulis sacrifice was for naught and seeing dragons in the flesh is going to leave him profoundly disillusioned. I don’t know if Dany will need to do more than show up and demonstrate that the prophecy meant her and Jon (and Tyrion) instead.
