So I actually don't have too much to say about Beta. The episode basically exists to set up Earthlings. Though we do learn some information on the beta kindergarten. It was made to pump out soldiers quickly during the rebellion. Jasper was created in this kindergarten, and she's the only one (that we've seen) that actually came out perfect. We also learn that Jasper has been keeping her "army" of corrupted gems here. We also see what Lapis and Peridot have been up to, which is nice.
And then there's Earthlings. Holy shit, Earthlings. I have so many feelings. So I'm not gonna recap the entire episode but AHHHH it's so great. So we get to Jasper again, which is great because I'm love with her. Amethyst tries to take her on by herself, but can't. Amethyst gets upset, but then Steven comes and gives her a pep talk about how they're alike and have each other. They hug, and then...
FUCKING SMOKEY (SMOKY? IDK) QUARTZ. STEVEN AND AMETHYST FUSION. THEY'RE SO PRECIOUS LIKE SERIOUSLY I LOVED EVERY SECOND THEY WERE ONSCREEN. I didn't expect Steven's first fusion with a gem to be with Amethyst, but I'm so happy with the way it was done. It almost makes you think that it's out of the question that he would have fused with any other gem first. So of course Jasper wants someone to use with, and actually attempts to fuse with a corrupted gem. It doesn't last long, as Smokey Quartz is able to separate them quickly. However, Jasper begins corrupting as a side affect. Many people saw this coming, including me. Steven tries to help, but Jasper refuses, and actually gets a surprisingly sad monologue about why she hates Rose for what she did to her colony, planet, and diamond. Not Yellow Diamond. Pink Diamond. So Rose did something (maybe shattered?) Pink Diamond, and Jasper is upset. She corrupts fully, and Peridot FUCKING PIERCES HER WITH A METAL BAR LIKE DAMN PERI, Jasper gets poofed, and Amethyst bubbles her, while saying "come here, sis." You guys. This episode fucked with me. We got a cool new fusion and CORRUPTED JASPER. So, what does this mean for Jasper? Well, I doubt the show is gonna get rid of her. In fact, this may actually be the setup to her redemption arc. I had doubts about whether or not she'd get one, but I think it might be possible now.
