But it isn't!

Homeworld is full of Gems who are created knowing exactly what their stories are meant to be, but Earth is full of Gems who decided to be something more. Pearl was designed to serve, but that's not what she is now, and it hasn't been for thousands of years. Sapphire was designed to spend her whole existence telling Blue Diamond how to direct her armies, but now she's half of the fusion who's leading the rebellion. Amythest is more than a soldier. I'm more than a coloniser.

And you're going to be more and better than what you were designed to be, just as soon as you stop believing that your design is your destiny.
