I've been seeing Steven Universe fans asking this question....
How does White Diamond know what happened to Pink Diamond, who Steven is, and what a human/half-human is of she's been locked away in her ship on Homeworld for thousands of years?
I think I know how.
Remember those white lumonious butterflies that appear time to time on Steven Universe?
I believe those butterflies are created by White Diamond and they are her in her spirtitual form.
Also, think about it, they look like White Diamond when she was in her ship.
Bright and lumonious. And she also seems to create light too.
So, that's why I think the butterflies are her's.
And I think she created many after the Rebellion and sent them to Earth so, she can watch everything that's going on.
The butterflies were also in Stevonnie's mindscape in Mindful Education.
And guess who has mind powers?
White Diamond.
Also, notice how the butterflies went to Steven twice in Serious Steven? I think that was really White Diamond focusing on who she thought was her "youngest daughter", Pink Diamond when it was really her "grandson".
So, I really think if Steven talked to one of the butterflies, White Diamond will speak through it.
And now she's a loving "grandmother", she'll probably send more butterflies just so she can be there with her "grandson" spiritually.
I also think her room is infested with the butterflies as well.
Anyway, I just wanted to share my speculation. What do you guys think? Do you think the butterflies belong to White Diamond too?
