As we know, White Diamond (along with the other Diamonds) got a change of heart and is now Steven's loving but awkward "grandmother".
And something tells me that part of her fullfiling her role as Steven's "grandmother" is doing the right thing and giving her "grandson" Pink Pearl because she was his mother, Pink Diamond's Pearl.
I also think that Grandma White Diamond give her to him on his birthday (It's a given that the Diamonds will be at Steven's birthday because they're essentially his "family").
Then, if that happens, it's inevidable White Diamond will get a new Pearl to replace her. (And since the Pearl will be a brand new Pearl, it's given she'll be the gem equalivalent to a baby and will act like a baby and small child. She'll be White Diamond's new baby Pearl and I can see her acting like a new mom with her brand new Pearl because she'll essentially have to relearn how to be a good "mother" and learn how to be a good "grandmother" and I can see White's hypothetical new baby Pearl being just adorable)
Anyway, what do you guys think this happen?
Also, I did do acouple posts on this speculation and White's possible new baby Pearl.
