Daenerys Targaryen, 'Mother of Dragons,' Daenerys the 'Unburnt,' is Azor Ahai returned.
She fulfills the ancient prophecy: Star, Salt, Smoke, Sword, Sacrifice, Dragon, Blood. With Daenerys' brother dead, that makes her the rightful heir to the Iron Throne.
The big twist may be that Jon Snow and Daenerys share the same noble mother.
Interestingly, Snow slightly fits into Azor Ahai's prophecy - The magic sword, coming back from the dead. Will we eventually see him riding one of Daenerys' dragons in the future?
Glad they brought back the Dothraki storyline. Got to love the muscularly men.
