since everyone was saying she was foreshadowed like this. it fits her a lot, i think! gives that creepy doll vibe.
if you look a little closer, there’s a gash on her stomach that reveals her gem. this is a reference as to how Cloud Connie was sliced in half by the real Connie (if it’s really a foreshadowing of WP, then i’m REALLY worried for her.)
I have a theory on what exactly WD’s powers are: Permanence.
We know that YD can poof gems, and was able to heal the majority of Nephrite’s physical form. She has powers over gemkind’s physical projections.
BD obviously holds power over the emotions of gems, and their minds. She was able to heal Nephrite’s speech and return most of her mind.
PD healed the last bit of Nephrite, her ability to process. Her aura has the ability to speak to gems telepathically, and communicate effectively even with ones whose minds should not be able to understand(Nephrite, the Cluster).
Nephrite was fully healed and functional, until the three diamonds let go of her, which caused her to revert right back to being corrupted. Blue mentions that White might be what was missing.
White is… different. Blue and Pearl said it themselves. She obviously is implied to be the most powerful of the diamonds, as even Blue and Yellow seem to fear her. What could she possibly inflict that another diamond would fear?
White has the ability to harm gems in a permanent way. Even if a gem she strikes reforms, the damage remains. That is why her pearl’s eye is missing, but her gem unharmed. White will leave a lasting impact on gems without having to crack them, leaving them functional, but stricken with a wound that will always remind them of their insubordination, their powerlessness, their unimportance. No matter what another gem tries to do to reverse the damage, only she can undo it. Not even another diamond (or three) can make any lasting change to her work.
