White Diamond has finally appeared. Holy ****.
I expected her to be amazing and likely nightmarish, but just like Pearl explained, she really isn't like the rest of the Diamonds. She's much more godlike and unnatural-looking, not to mention even bigger and taller. It seems like her own body is projecting a bright light, so much of it in fact that it's hard to get a detailed look at her.
Not helping matters is that she didn't move at all during her first scene, stuck in something akin to a t-pose. Her Pearl is the same way, and also moves via levitation, doesn't share the same voice of other Pearls, talks rather like a robot, and has a freaking scar where her left eye should be. What the heck. Permanent injuries are not normal at all for Gems, and despite behaving unnaturally, she doesn't appear to be defective otherwise. If this Pearl isn't just a flat-out puppet directly controlled by White, then she's probably instead been thoroughly broken by her. There's also evidence that the scar came from her Gem possibly be forcibly removed from it's original placement, somehow. That's not normal either, to say the least....
To top it all off, White says things that make her seem very understanding and forgiving of Pink's actions....but her calm tone sounds very off and forced, and combined with her choices of words it makes her come off as very passive aggressive. Like she wants to handle things calmly with Pink, but is actually absolutely pissed, and that she could lose that facade and burst into pure rage at any second. Which is made all the more unnerving by the fact that she is more than likely the most powerful and godlike out of all the Diamonds
In short, I'd call her terrifying and enigmatic. I've been waiting for White's reveal for so long now, and I am not disappointed. I'm hyped for the rest of this season!
