I will admit that I wasn't suuuuper impressed by the episode, mostly because there is a disproportionate amount of screentime devoted to the fight scene, which frankly felt a little meh. (It's a bit of a problem with this series in general... Tons of fighting to show off the cool CGI, but very very basic plots.)

But the rest, basically all the points you highlighted, were pretty cool! If you write, I'll read :D
