I've seen a decent chunk of Steven and Amethyst friendship fics over the years, and honestly, a lot of them hit on the same notes—Amethyst's self-worth issues, Steven's optimism. It works, but I've been hunting for fics that flip it. There's this one where Amethyst, after the Diamond stuff settles, starts trying to teach Steven about being messy on purpose, like, not everything has to be a healing project. It's less about Steven fixing her and more about her showing him it's okay to not be okay, to be a bit selfish sometimes. The growth feels mutual instead of one-sided.
Some writers get really clever with the shapeshifting aspect. I read a fic where Amethyst uses it to help Steven process grief, shifting into memories of Rose so they can both talk to a version of her, not to replace her but to argue with the idea of her. It was raw and weirdly cathartic, focusing on emotional tools rather than powers. That angle—using their unique abilities as metaphors for emotional labor—always sticks with me more than the straightforward comfort fics.
