Why did Kaguya ask Finn to bring her a moon stone? Because to her, the moon looked just as lonely as she felt. However, the moon wasn't alone at all—it could always count on the sun to lend it its light.

Himiko must have put her up to it—which, when you look past the embarrassment, proves that Kaguya is no longer alone either.
