Yes, the secret about Jon/Aegon is officially out, and Varys and Tyrion are thinking about damage control. "Maybe Cersei will win and kill us all, that would solve all our problems," Tyrion muses. That's seeming more and more likely, too, as Dany and her dragons almost make it home to Dragonstone, but are ambushed by Euron and the Scorpion weapon, which quickly takes out Rhaegal. The Greyjoy fleet then decimates the rest of the Targaryen ships...and that felt way too easy. Also, R.I.P. Rhaegal!!!!
We don't even have time to mourn, though, because back at King's Landing, Cersei is trying to seem like a nice person by sheltering people in the Red Keep. She tells Euron she's pregnant with his child (false) and that their Lannister-Greyjoy child will rule the seven kingdoms (ugh, vom). We see that Missandei is her prisoner...and we almost feel more nauseous about this episode than we did during last week's battle.
Another quick convo between Varys and Tyrion: this time, about "the realm," who the true leader should be, and whether Dany/Jon as a couple (Jany, if you will) would be able to rule the Seven Kingdoms side by side as husband and wife. Varys reveals that he really would turn against his dragon queen if it meant saving more lives of the "realm." Tyrion begs him to remain loyal and not turn his back on her, but it's looking like that ship has already sailed. Varys is a true betting man.
Back at Winterfell, Jaime leaves for King's Landing, but not before telling heartbroken Brienne that Cersei's hateful, but so is he. Whether Jaime's reverting back to his old twin-sister-loving ways, or hoping to exact his revenge, the jury's still out. We're wailing with you, Ser Brienne.
