>>101841488Jasper is a tragic character who has shitloads of issues and trauma and still tries her best. She's also kinda badass.
She goes well with Pearl because they're the sort of opposites who'd complete each other; Pearl wants someone strong (she has a type) to fuse with and needs to be her own gem and get over Pink and be appreciated for who she is, meanwhile Jasper needs to be accepted and appreciated, needs to experience a couple of consensual fusions, needs to learn to appreciate Earth and come to terms with being an Earthling. Pearl was PD's personal pearl and understands better than no-one what went down with Pink and Earth, and could help Jasper come to understand and accept that. Jasper's from Earth and hates herself because of it, because she's been made to believe Earth fucked everything up and led to her diamond being shattered and all the Earth-made gems labeled as tainted or defective - but in truth, her diamond loved Earth so much she gave up everything to protect it. They're also both formerly PD gems.
Also they both have a muh battle glory and honour boner, love to win, are smug as fuck when they get the chance and are a bit anal about things being done right, and so forth. They're both veterans, formidable in their own ways - Pearl has risen above her original station and learned to fight and be a skilled tactician, sort of embodying the "grow and choose who you want to be" attitude Pink idealised, Jasper appreciates tactics and so on and so on.
