Promotional clip + boredom = this.
Steven and the Crystal Gems watched in shock as Centipeetle, freed from corruption, returned to her original form. Once she finished materializing, she turned around and revealed herself to be...a Variscite?
"Who...helped me?" said a Peridot-like voice.
Steven took a couple steps backwards, too shell-shocked from the revelation to speak. Centipeetle turned to look at the boy, eyed him...and left him something before promptly fleeing.
