clearly-clarity:

Can we talk about Amethyst in this episode though? She usually clashes so often with Pearl, but in this case she literally defended her when Pearl admitted that she lied. And remember that part… where Amethyst looks down a bit sadly and says “No, I don’t think that’s it” when Steven asks if Pearl wanted to learn about the communication hub. And I think it’s because Amethyst relates to her. She really gets Pearl, because she feels the same way herself.

She basically says, “We both feel stronger with you” and I think it’s because fusing with Garnet makes them both feel like they’re loved, and Pearl wanted to keep doing that. Amethyst feels the same way. Both of them struggle with serious issues of inferiority and feeling unwanted, and fusing with Garnet seems to alleviate that, if even a little.
