Who Is This Man?
We interrupt this flurry of frenetic action and suspense to ask -- who is this mystery swordsman? His face is deliberately obscured and he's in a brand-new setting for the trailer. Still, using a bit of insider knowledge, this looks like the Italian ruins which are rumored to play the part of the Dragonpit -- a location in King's Landing in where the Targaryens of old used to house their dragons. As for the man, our best guess is it's Sandor (or the Hound if you like), now basking in the warm sun after his trip up north.
If true, then he's in King's Landing for one reason and one reason only -- to fight his brother, the Mountain, in the dream showdown long held by fans called "the Cleganebowl". There's obviously a lot of speculation surrounding this particular shot, including set reports that these Dragonpit scenes included more of the core cast than any other scene and theories that by this point Sandor has been killed and resurrected by Thoros of Myr, only it was a botched revival and he's now a zombie like his brother. Whatever is really going on here, it's significant, otherwise it wouldn't be so mysterious.
What follows is a montage mostly comprised of scenes which back up the suspicions raised by previous shots in the trailer. Jon confides in Davos, likely before or just after his first meeting with Daenerys on Dragonstone; Jon fights a White Walker, again using his Valyrian blade, Longclaw to parry their attack; more from the field of fire; another shot of Theon and his few Ironborn coming ashore and looking defeated; the trailer's one and only shot of Euron, here likely taking part in that fiery sea battle; and Daenerys sitting rather triumphantly atop Drogon.
As has already been made abundantly clear, season 7 will manage to fit in a lot of stuff for only seven episodes. Just in this short blast of shots alone, the trailer jumps from Jon fighting White Walkers to the battle between Yara and Euron's fleets to Daenerys' dragons scorching her enemies where they stand -- all big action set pieces that in previous seasons would come only after an episode or two of slow and deliberate developments. Season 7 doesn't have that kind of time and this trailer practically promises what it does have will be action-packed.
"The Lone Wolf Dies"
Bringing everything back around, this second Game of Thrones season 7 trailer ends on two core elements of the series -- "Winter is Coming" or rather, it's here, and the family famous for uttering those words. They were the first family introduced, the one that deep down we're all rooting for, and the family subjected to tragedy after tragedy. Every win for the Starks usually comes tinged with loss, and it'd be foolish to expect anything less from season 7.
A slow progression of shots -- an unlucky group, either Jon's or Beric's (or both?) surrounded in a snow storm; a lone survivor (possibly Sandor?) fleeing on horseback; Jon cutting down an attacking wight -- all set to Sansa's solemn voice over: "When the snows fall, and the white winds blow, the lone wolf dies, but the pack survives." The phrase is a favorite of Ned's and one that in the novels, Arya finds herself remembering, placing herself in the role of the "lone wolf" and relating pack with her surviving family members. Here it's Sansa, but it's still Arya who remains separate from her siblings, her pack, and that isn't a good sign.
It's a chilling end to a frenetic and fast-paced trailer, evoking the stubborn spirit of the Starks and teasing their potential return to power. But it's also hard not to read that phrase, "the lone wolf dies", as something ominous, even if "the pack survives" in the end.
