Lion Pink Pearl

Well... I'm not arguing with your theory, because I REALLY love it.  At first, I thought our Pearl would have been Pink Diamond's, given the jumpsuit she wore in the spaceship episode, but she might have been given to Rose instead.  Rose WAS a pretty high-ranking officer before the rebellion, I think.  Pink Diamond could have seen fit to gift her with a Pearl.  I mean canonically, not in your comic's plot where she's White Diamond's, but...

Well, we won't know what's canon until it's on the air.  With theories, as with so many other things, to each their own.  I for one am just looking forward to seeing what happens if and when any new episodes come out.  And who knows?  One day we might actually learn Lion's origin.  Canonically.
