Steven’s smile faltered, but he met her eyes. "Maybe I’m not trying to fix you. I’m... trying to remind you what you already are."

Wait, maybe the user wants a story where Steven is the one "unleashing the light switch," as in awakening his true self. So a story where Steven has to confront a part of himself he's been unaware of, perhaps tied to his role as Steven Universe. Maybe a realization about his power or his parentage.
