It seems that I missed quite a bit while I was out today. A shame, but nothing to worry about. So, do you guys remember that theory I put up a little while Back about Rose being one of the very first to experiment with clusters? What if all of the corrupted gems are the few gems that Rose was able to find the pieces of, and attempted to restore them as well. Since We saw the gems of the clusters trying to escape before having a solid form, it reminded me a lot of how Centipeedle briefly had a similar humanoid silhouette before re-Centipeedle-ing. Amethyst's case was different since her gem was only cracked, but I think that she'd end up like the other gem monsters if her gem was shattered and Steven tried healing it.
