The Narrow Sea passage to King's Landing
What happened: Daenerys Targaryen ended Season 6 with a fleet of Greyjoy-, Martell-, Tyrell-, and Targaryen-branded ships she looted after killing the masters in Astapor. She's riding the waves with 100,000 Dothraki screamers and their horses, plus 8,000 elite Unsullied warriors, plus three fully grown fire-breathing dragons in the sky.
What will happen: Based on her course, many assume Daenerys will, at long last, engage Cersei's army at King's Landing. Concept art that trickled from set strengthens the argument -- if you're a spoilerphobe, skip ahead.
The painting depicts a ruin adjacent to King's Landing known as the Dragonpit, where we expect Daenerys will lead Tyrion (Peter Dinklage) and her allies to a wight. Set photos confirm that nearly every Thrones star was present for the shoot, including Harington as Jon Snow and Headey's Cersei. One spy shot even sees Snow shaking hands with Tyrion, a sight we haven't seen since Season 1. Is this the super army that can take on the Wall? The alliance won't be that easy to pull off -- onlookers also caught Emilia Clarke on set for Nikolaj Coster-Waldau's big army battle, leading many to believe the season's big action sequence will pit Daenerys against Jaime.
