So, I'm rewatching the show and taking screenshots of interesting objects and characters and making new observations, one of which is that in the episode Serious Steven the mechanism powering the pyramid-like battle foretress is powered by a white gem. The mechanism surrounding the gem is black, white and grayscale, much like Zebra Jasper, whose identity hasn't been determined on the wiki yet and who is among the gems that got uncorrupted in Change Your Mind.Â
She is the only one whose colour scheme and approx. gem shape matches this unknown gem. I'm posting here to hear what others think about this, and whether this should be added to her wiki page. Photos to check out for yourself
