While Daenerys may have won, is she really a victor? That's the line she used while trying to convince captured Lannister army members to join her, and it probably would have been a lot more convincing if she didn't follow it up by literally annihilating Randyll and Dickon Tarly with dragonfire. And, their master plan sounds pretty unbelievable as they intend to catch a white walker (REALLY). Basically, she ain't gonna win. Even Qyburn's Scorpion failed to bring down Drogon, which was inarguably their best shot at beating Daenerys.
While we knew that Rhaegar Targaryen had been married to Princess Ellia Martell due to there being no suitable Targaryen women for him to marry, we didn't know that their marriage was annulled in Dorne and that Rhaegar had taken another wife.
After three seasons away, Joe Dempsie finally returned as the bastard son of Robert Baratheon, last seen rowing away from Dragonstone in the season 3 finale.
There is a more Targaryen in Dany than I sometimes care to contemplate. Now, it looks like he's gonna be plotting behind her back to manipulate her. Tyrion knew what he was doing was stupid, but he needed to do it, and Rhaegal and Viserion were fairly accommodating. As Bran Stark (Isaac Hempstead Wright) teased in "Eastwatch", the Night King and his army of thousands are heading to Eastwatch, one of the easiest points to circumvent the Wall created to keep them out of Westeros.
As Daenerys said, perhaps Tyrion doesn't want to hurt his people after all. A moment is shared between the two strangers; something that doesn't go unnoticed by Daenerys. So basically, everyone fighting for the Iron Throne, even the mother of dragons, can GTFO because it belongs to Jon.
Moving to Winterfell, Arya's relationship with her big sister Sansa Stark is becoming very icy as days pass by. And she actually kinda does.
At the Citadel in "Eastwatch", Gilly read off Seven Kingdoms trivia while Sam tried to do his boring work and stewed over being blown off by the old maesters in his quest to help defeat the White Walkers. Not only does Gendry know his true heritage, but he also told Jon Snow (a fellow bastard), who knows that allying with Gendry means that they have more great houses at their backs. So yeah, technically, it should be Daenerys bending the knee.
