Although I thought the part of the other Amethysts teaming up with our Amethyst was a little odd (I mean just because they're the same kind shouldn't automatically make them on her side), though maybe it made things easier to reason with them. I loved the Skinny Jasper though. Also I think the red one was a Carnelian.
Well Holly Blue Agate aims to impress, but I still like her.
And poor Blue Diamond, she must've really loved Pink Diamond and wants to preserve her memory. Poor thing.
The last escape part was really awesome though!
Overall, I'd say this arc was like the next "Jailbreak" arc, and it was really darn cool!
