Talk:Back 2 the Moon Part 3/@comment-26548131-20150904110358

Beta = Pearl (because she's the beta, and that's also what she thinks of as herself)

Earthlings = Amethyst (because she was born on Earth)

Back 2 the Moon = Garnet (because "2" the moon, and she's a fusion)

I'm gonna guess these episodes have to do with their lifestories, or how they met Rose, it could be anything.
