It would only make sense that the Iron Bank's final move would be to back the most stable investment: Daenerys Targaryen and her three dragons and two armies.
In the end, the biggest thing that Westeros can possibly hope for at this point is for her to receive some good news that he is still alive, given that you don't want her getting into some murderous rage where she just starts to destroy anyone and everyone around her. This clearly contributes to the dire situation in Kings Landing with no grain and limited supplies. If she does, it could be ammo for Jaime to turn his back on Cersei and side with his younger brother. But it's also a lesson Sansa learned the hard way and strengthened after witnessing what none of the other Stark children did, like the beheading of her father.
The last Game of Thrones just gave us the "Loot Train Attack" (yes, that's what it's officially called) and a lot of fans were absolutely floored by the sequence. And there's also no glimpse of what's happening at The Wall, which is suspicious for an episode named after the fortress Eastwatch, based by the frozen sea. They're seeming more Team Targaryen by the minute. The promo opens with Daenerys (Emilia Clarke) asking the remaining Lannister soldiers to pledge their loyalty to her and "bend the knee". The scene ended there, but when we see them walking out of the cave he's trailing a few steps behind, as, say Prince Philip does behind Queen Elizabeth II. She seemed anxious for his counsel.
Fan theories suggest that Drogon's life is in serious danger after being wounded by the Scorpion aka Qyburn's (Anton Lesser) massive crossbow machine. Are the arrows poisoned?
The opening scene of the entire season - in particular, Arya's "tell them Winter came for House Frey" drop-the-mic moment - seems to have spiked our heart rates more than any other non-action scene. Bran has already confirmed that Ayra has a to-kill list. Meanwhile, Sansa, too, is anxious about grain supplies and feeding her own people. Still, Euron Greyjoy, who has her, and his fleet must be reckoned with.
What role might the Hound and the Brotherhood without Banners play?
In new stills from the forthcoming installment, titled Eastwatch, Tyrion Lannister is seen grimly surveying the scorched landscape in the ensuing aftermath.
