I can see Snow being it. Theres no way in hell stannis is, he seems too fake and I trust what Aemon said regarding Stannis's lightbringer having no heat.

Id hate if Vicatarion was even just 1/3 of the dragon's heads...even though it would fit.

If more than one person could be Azor...then id want Dany, Snow, and Tyrion myself. Id rather bran played a strong role outside of everyone else. That role could be working with or against the others...idc.

Also ya, Kevan dying was pretty troll. It was as if Martin was just like "ok, now everyone thinks he matters....PSYCH, JK HE DEAD NOW LOLOL"
