I really don't think that Jasper will be redeeming herself, at least any time soon. As we saw, she was after Lapis in order to fuse again. She doesn't see Fusion like the Gems do. To her, Fusion is only an increase of power. I don't feel bad for her at all. The beef between Jasper and Lapis seems like some sort of abusive relationship. Yes, Jasper is a horrible individual, and supposedly Lapis is as well/was at some point an even worse person, but the two have this warped bond that keeps them in each other's minds, thinking about the other and wanting to feel the power rush that is Malachite. Lapis know's that it's a bad idea. She refuses to go back into that relationship with Jasper, even though she wants so. She knows how much power they'd get, but at the cost of her own sanity and personality.

with fusion on the mind, I'm also thinking back to Peridot. Peridot almost fused with Garnet. For whatever reason, something was stuck in her mind, and she quickly refused to do it. As revealed this week, Peridot cannot shapeshift. Era-2 Peridot's are not made the same as Era-1 Peridots are, and because of the dwindling resources of Homeworld, shortcuts had to be taken. Peridot cannot shapeshift. Normally, I'd go into things, but her not being able to bend her physical form like the other gems do does bring some things into question. Because of this, it doens't seem like she'd be able to fuse either. Maybe she was scared that Garnet would find out that she can't even fuse, letting people down even more than she already has. I don't know for sure, but it's something to think about.

Since we all know that SU essentially finds adult human issues and explains them to kids metaphorically, in a lighter tone, I think that Jasper and Lapis's fusion withdrawal mayyyyyy(sarcasm) be a representative of drug addiction.

That's one way to look at it, and there is a case for it, but I'm more in the camp of people who say it's an analogy for an abusive relationship. Considering how fusion has always been likened to a relationship, and the fact that dialogue between the two is reminiscent of such a situation(especially from Lapis' point of view of how she missed being malachite).

Aside from that, is anyone else more interested in Lapiz's backstory after hearing about how she liked to push Jasper down and how Jasper said she was the worse of the two? What secrets is our Eli teen gem hiding from us I wonder?
