”Crystal Sapphire! You are needed immediately.” Crystal nods distantly and closes her eyes, seeing a mental map to where the Great Diamond Authority awaits her. She pauses in front of the White Diamond and salutes her. ”My Diamond.” 
White Diamond dips her head in acknowledgment. ”Crystal Sapphire, we need you to inspect a group of rebel gems, which call themselves the Crystal Gems. Change, and leave tonight. You will be undercover and report to us periodically. We need as much information on this group as you can gather.”
Crystal curtsies, and bows her head. ”Of course. Whatever you wish, for your wish is for the best.” At a small noise from White Diamond in dismissal, Crystal turns and leaves.
