For all intent and purpose, White Pearl Is White Diamond. She is a mouthpiece, a glorified phone for White Diamond to speak through. Why do you think the other diamonds are so afraid of her? She barely has any sense of self anymore.

I still cant tell if they are trying to set up White Pearl as the secret villian, being the past Pink Pearl, who now seems like a puppet but shows such intense disdain for her former diamond breaking the laws of their world. Is she enforcing White's laws? Or is she pissed that isnt her by her old diamond's side anymore? .
