I feel it’s not only Garnet, but also Pearl who regularly mediates to centre herself.
When Garnet and Steven arrive at the very beginning of Adventures in Light Distortion, Pearl is on the ground looking despondent.
It is only a short while after they arrive that she make a face as if surprised, which means she wasn’t already aware of their presence earlier.
And then she stands up and says, “Oh, you’re back!”
That she and Amethyst had relieved and almost glad reactions to their return shows what I feel implicitly goes on between the gems. I’m willing to bet Garnet told her and Amethyst nothing about where she was going, why she was afraid, and what she was going to do. All they likely knew was that she was going to find Steven.
And it speaks of Garnet’s action-orientedness in times of conflict, but how it can also cause the people around her to worry without her meaning to cause them stress. Pearl mediates too, as much as it would seem like she just lets her feelings explode around her.
It’s a testament to how well the Crewniverse understand the cartoon short format. This scene made full use of moving images and sounds and that’s what made it so compelling and urgent. Just posting the photos could never capture the feeling. What they’ve accomplished requires a deep familiarity and respect for the medium.
