Game Of Thrones Season 7 Implications: What "The Queen's Justice" Really Means
3. Highgarden Falls
With Tyrion ingeniously sending the Unsullied to Casterly Rock for a symbolic victory over his family, his plans were pretty horribly undone by the fact that Cersei sensibly abandoned the place as a pointless landmark. Instead, she and Jaime attacked Highgarden - mimicking Robb Stark's victory over the Lannisters at the Battle Of Whispering Wood - and defeated the Tyrells in a battle so resounding that we didn't even get to see it on screen.
And thus falls the House Of Tyrell, whose riches will now be swallowed up by the Lannisters - and used to pay off the Iron Bank - while Dany has once again lost a valuable ally.
Incidentally, it's an outrage that all we've seen of Bronn so far is a tiny flash of him looking cool on a horse behind Jaime. He's being badly underused - though there is some solace to be taken in the fact that he hasn't just been killed off as a superfluous character yet.
It's probably still coming though.
