Steven Universe, Season 3

[Greg, Rose Quartz and baby Sour Cream lie down on the beach under a parasol]

Rose:
You wouldn't believe how long it took me to figure out that this and you are the same thing.

Greg:
[beat] What do you mean?

Rose:
You're both human! You have to admit, it's a little confusing. You're big and can talk, and he's small and can only make noises. How was I supposed to know you were the same species?

Greg:
[chuckles nervously] What?

Rose:
I know, it's silly. But then I started to notice that... you grow.

Greg:
Well, can't play guitar with little baby hands.

[Rose giggles and then pauses for a moment]

Rose:
When a gem is made, it's for a reason. They burst out of the ground already knowing what they're supposed to be, and then... that's what they are. Forever. But you, you're supposed to change. You're never the same, even moment to moment—you're allowed and expected to invent who you are. What an incredible power... the ability to grow up.

Greg:
[pause] Wow. Those would make some pretty good lyrics. Hold on! Watch Sour Cream a second. [runs off] I gotta write this down!
