He wants to feel good from the inside, but he doesn’t know how to do that. They, all having new powers that are more altruistic in focus, try to help Steven, but he doesn’t want superficial changes. He ends up giving in to that malevolent side of himself and accidentally shatters Jasper, so he flees to the Diamonds for answers. The problem is that Steven digs down too deep and starts going Tetsuo. Steven is angry and afraid of that anger, so he goes to Jasper, someone who can teach him to harness that anger. Greg recounts a very laced up, conservative family that didn’t let him do anything, but what Steven sees is the stability that he has been denied. When his Greg returns early from tour to take care of Steven, we get another episode where they revisit Greg’s childhood. Steven recounts all the things that have happened to him, all the physical and emotional pain throughout the series, and he’s told that his body is reacting as if it’s the end of the world to every single bit of stress-because that is the kind of stress his body is used to.
It’s stated that they healed as soon as they happened, but the cracks are still there. Connie’s mother examines Steven in the hospital (his first doctor’s visit), and we see an X-ray of his skull, showing fractures there, as well as other parts of his body. In “Growing Pains,” the story finally addresses what’s going on: Steven is suffering extensive psychological trauma. He has never been to school, he doesn’t really have any employable skills, and because he is older, all of the things he has suppressed inside of him are no longer able to stay there. That leaves Steven to realize that he does not have a purpose of his own. Connie is in school preparing for college, and Greg is on tour with a new band. Garnet, Pearl, Amethyst, and the others have jobs and lives outside of just Steven. His powers are still growing, but there are not really any battles to fight. Steven is restless and largely purposeless. At the beginning of Steven Universe: Future, our hero is living in the utopia he created.
When Steven Universe ended, he had saved the universe, convinced the Diamonds to stop being despots, and brought back the corrupted gems of Earth. Nothing really sticks to them, and they are able to bounce back from their trauma because saving the world is worth it in the end. When it comes to child heroes, they are usually portrayed as a sort of emotional Teflon. In the final bunch of episodes of Steven Universe Future (which I binge-watched this weekend for maximum tears), we saw our hero, Steven Quartz Cutie Pie DeMayo Universe, deal with the fact that he may have saved the universe-but it left a lot of scars that need to heal. What do you do after saving the world, instilling democracy across the universe, and ending an era of brutality and warfare? You realize how none of those things have prepared you for the simpler things in life.
