The trailer seems to confirm a great many rumours we've been hearing about season 7, including Danaerys in her ancestral home of Dragonstone, and that definitely sounds like Jon Snow making a plea to Dany in the voice-over. (Also, is that... is that Cleganebowl?). As for our fears, well, the White Walkers look to be making their move, a lot of things are on fire, and Sansa seems to be pretty confident not all Starks will survive the season.
Check out the 2nd trailer below:
Not long to wait now!
