Alliances were the driving force behind the newest episode of "Game of Thrones."
On "Stormborn," Daenerys received an unexpected visitor in Melisandre, the Red Priestess who believes she and Jon play a central part in a prophecy about a great hero. Meanwhile in the North, Jon faces a revolt when he decides to accept an invitation from Dany to meet with her in Dragonstone. And while Tyrion thought he had the conquering of Westeros all planned out, an attack by Euron wipes out many of Dany's allies.
