Previously on GoT: Cersei Lannister screwed over Daenerys Targaryen by taking down her dragonless allies – Yara Greyjoy, Ellaria Sand, and Olenna Tyrell. Jon Snow took Daenerys into a cave and showed her some things. And then Dany torched a decent chunk of the Lannister army with her dragon and almost killed Jaime.
That’s right! Jaime Lannister is alive! And so is Bronn! And they got away and are totally fine and not even injured!
