Did this come up in the dialogue? No one has commented on it yet. The tv version places great weight on Melisandre's belief in the power of the blood of kings, but the Azor Ahai issue is something quite different. The tv version hasn't set this up, but if it's integral to GRMM's plot outline, it has to be introduced at some point.
I would be surprised if Stannis turned out to be Azor Ahai, but GRRM is in the surprise business. This is why he complicates the narrative with so many characters, many of whom are false leads, and disposable.
It is also worth remembering that, in the book version, burnings are not always what they seem.
Very good points. I don’t think we’ve seen any cases of “glamoring” in the TV series - except for the Faceless Men. They haven’t really gotten into the details of Azor Ahai much, but what happened with Shireen seems unrelated to that prophecy. It all seemed to be about Shireen and her having “king’s blood” in order to get the weather to clear up for them.
