I don't know. Part of me doesn't want them to just turn Jasper (and Peridot to an extent) into redeemed characters. Considering the seriousness the show does give off with what's going on, Steven turning them nice with The Power of Friendship sparkle sparkle rainbow seems like it wouldn't fit.

Could they come up with a reasonable way to take their characters? I don't doubt it. But so far, I'll be on the fence about actual redemption. Especially since we'll inevitably have Lapis joining with them whenever the Malachite plot is resolved.

You kidding? Redemption and the power of love are this show's bread and butter! Just think about everything they've done with the bubbled gems, those aren't just there for decoration, they're there for the gems to fix when they figure out how.
