It appears to be a peaceful submission, the castle taken without a fight. Given her dragons, I’d surrender too.

Daenerys sits on the high seat at Dragonstone. The men opening the door and guarding her on either side appear to be Dothraki.

Grey Worm is ready! Note his new silver Targaryen badge. It will help us find him amidst the chaos when his facemask is on.

Case in point re: his new insignia… We can tell this is Grey Worm because of it! This Lannister man he’s facing has no chance, we’re thinking.

No Grey Worm here that we can see, but we wonder what Lannister site this is (note the sigils and “L”. It could be King’s Landing, or less likely, Casterly Rock.

Melisandre at Dragonstone! The previous shot makes it clear that it’s her. We can’t tell who that is coming up the long walkway, but if Davos is one of them…

Dany & Tyrion view the Painted Table at Dragonstone.

Cersei and Jaime one-up Daenerys’ puny Painted Table with the Painted Floor. Ok, it’s a tapestry, but still, it’s huge, and awesome.

Jorah appears to be held in prison, probably at Dragonstone. Clearly him due to the greyscale.

Other shots seem to show that they are facing a Lannister army. It doesn’t look like Dany is on Drogon, but it is hard to tell. It looks like Jorah leading the charge in the bottom right… Dany may forgive him? Or at least allow him to fight. Or maybe that isn’t actually him.

Ellaria and Yara making out. Alrighty.

Greyjoys fighting others in a boarding action while flames roar. What shield is that in the upper right? Another shot shows Theon on a flaming ship, so this could be the same scene, meaning that Theon is somewhere in this chaos.

Appears to be fighting across a rope bridge, which means it is probably Pyke. A battle at Pyke! Interesting…

Looks like Arya is heading North, unless winter has hit the South (certainly possible!)

Jon is joined by Sansa and Davos at the high table. Littlefinger far to the left, Lyanna Mormont near the front behind a large man. Tormund can be seen as well, and probably the top of Brienne’s head in front of Sansa.

Jon Snow slams Littlefinger into a wall while in the Crypts of Winterfell! (recall when Ned did this to him in King’s Landing?) Possibly he’s just been given some news about his real parents.

Jon, Tormund and others are running from something. They appear to be beyond The Wall.

Possibly related to Jon & Tormund running away, this group of 12-13 men in heavy snow appear to be surrounded and making a stand. Seems likely the foes around them are not among the living…
