I've been staying away from most of the internet for the last 3-4 weeks so that I don't get spoiled, with pretty big success. I'll try and summarise my thoughts on each episode quickly.
DBD: Pretty fun, I absolutely loved seeing Steven's superstrength finally being used and emphasised.
Mr. Greg: Not gonna lie, it made me ship Grearl very hard. Good songs (with the exception of the one they sung right before going to Empire City, not Don't Cost Nothing), very good animation, and seeing Steven forming a keikaku of his own was great.
TStR: I expected a fusion of any of the three, or a fusion of all three, but it was still good. Seeing new powers is always welcome, especially Peridot who didn't have any. Though it seems like some people still believe she can shapeshift, but I personally reject that. I think Metalbending is something all Peridots have that can't be "removed" (like Sapphires with future vision or Rose Quartzes with healing power).
TNL: I'm just glad that Lars didn't have any control over Steven's body. Pearl would have shattered herself if she saw Lars!Steven.
BCD: Being honest, I didn't watch it. I tried to but the video players wouldn't work for me. From summaries it seems that Steven was acting way, way out of character.
RW: It was funny, I feel really bad for Ronaldo loosing his girlfriend, but it was nice seeing two otherwise irrelevant background characters being relevant (Ticket Girl and Suitcase Sam). And it was a nice touch having the other three CGs unquestionably follow Steven with his plan, whereas they might have not done so or slipped up if they were the same as they were in S1.
KPDS: I don't have much to say about it. It was a nice, good episode, but I'm not really feeling compelled to watch it again.
MR: It was great seeing Peetle again, and it was sad seeing her getting corrupt again. Steven's healing power finally works again (though it's probably always worked, just in a different way), I'd definitely reckon that as good news.
AAS: I wasn't expecting to see Jasper this early, and desperately wanting to fuse with Lapis again. Pic below proves to be more relevant than ever, yet again.
GtB: Rose was a big goof, confirmed. It's almost a wonder she managed to lead a revolution. Maybe conversation and being social isn't one of her qualities?
GH: Nice seeing that Pearl is able to joke. Again, I didn't expect Jasper to be back THIS quickly, especially right after AAS.
CtW: Poor Amethyst, I felt really bad for her after I watched the episode. And about time that Stevonnie actually did something beside run, jump, dance, and give Lars an erection, it's just a big shame that it took 2 years. Too little too late, personally. Oh, and Jasper keeps getting BTFO'd.
Svs.A: I'm really glad seeing Steven training, but it's also really heartwrenching to see Amethyst still hurting. Steven's spike bubble was cool and a very pleasant surprise to say the least.
Bismuth: I was trying to stay away from judging Bismuth (the character, that is, not the episode) before I saw her episode, and now that we've finally seen it I have to say that she's probably my Worst Gem. I think that if the Breaking Point was actually used in the war, it would not only have escalated to an entirely new level, but it would have also created a divide between the Crystal Gems between those who were okay with shattering Gems, and those who only poofed them. This could've caused them to loose, considering that they just BARELY won and only three CGs survived, not counting Amethyst.
Beta: Not much to say about this, I guess it's good that Lapis and Peridot are able to get along, after all.
Earthlings: This really was a great episode, definitely a favourite and I could see myself watching this one time after time. I'm so glad that Steven finally fused with a Gem (though I'm sure you people already figured this by now) and though I did want him to fuse with Pearl first, I have to admit that it makes sense for his first partner to be Amethyst considering the development they've both gotten recently.
And I have to say, I really do like Smokey (Smoky?) Quartz. They had a great first impression on me, almost everything was on-point. Cute, fun personality, great fighting, and cool weapon. I'd definitely love to see more of them soon. But this is something I've kind of been wondering recently, did Rose and Amethyst ever fuse? It felt like the first time for them, but that could be from Steven being, well, not Rose.
