7 Things From the Game of Thrones Trailer That We Need to Discuss

"Enemies to the east . . . enemies to the west . . . enemies to the south . . . enemies to the north," Cersei Lannister says at the beginning of the trailer. And it's true: she's pretty much surrounded right now. Daenerys has combined forces with the Iron Fleet, meaning she's now convinced the Dothraki army, the Greyjoys, and the Unsullied to help her claim the Iron Throne. To the north, we obviously have Jon Snow and the rest of his armies. And let's not forget Dorne. Ellaria Sand clearly has a vendetta against the Lannisters. Will Cersei be able to take down all her enemies? Things are looking bleak.

Based on this trailer and the ones that came before, we knew Daenerys would, at the very least, claim one throne in season seven: the seat on the Isle of Dragonstone, home of House Targaryen. This means Daenerys has successfully made it to Westeros, and she's not far from King's Landing.

But that's not all! Another shot shows Arya huddled up in some icy woods. Does this mean she's made her way up North? Could she be close to reuniting with Jon Snow and Sansa? Now that Winter's here, she might be further south than we think.

Perhaps it's Ser Davos who seems most aware of the Night King's threat. Based on his counsel, it's clear he's worried about the White Walkers. "If we don't put aside our enmities and bound together, we will die. And then it doesn't matter whose skeleton sits on the Iron Throne." He's got a point: if all the houses spend too much time fighting among each other, they might not have the force or foresight to contend with the ice zombies from beyond the Wall.

OK, so, Yara Greyjoy and Ellaria Sand are definitely making out. This begs a lot of questions: how did they end up in the same place? Are they just hooking up, or is this some kind of half-boiled side plan to take over the Seven Kingdoms? Is Ellaria literally poisoning her in this very moment?! We're concerned.

Jon Snow is perhaps in the toughest position of all. Based on other shots from the trailer, it's clear the White Walkers have begun to infringe on human territory. We see some of the North's forces scrambling to battle and trying their best to survive the chilly blizzard conditions. At the same time, he must come to terms with the other "Great War." How will he play into the fight for the Iron Throne?

Littlefinger is working his own sneaky angle, and now we have proof. In the trailer, he's making it clear that Sansa is "the last best hope against the coming storm." Littlefinger doesn't want Sansa to rule in tandem with Jon. He wants her to wrench the title from his hands. In another scene (in what looks like the crypts), Jon Snow slams Littlefinger against the wall. Could it be about Sansa? Does it have something to do with his true parentage? If anyone were to know about Jon Snow's actual lineage, it would 100 percent be Littlefinger.

And then we have the dragons. They're bigger than ever, and Dany is rolling them out for battle. The dragons could prove to be the most formidable force in this last great war.
