Fans of the show know that I'm a bit obsessed with the show Steven Universe. In the off-season I find myself coming up with strange headcanon to make my world view more interesting. In addition to Garnet's voice, lent by the talented singer-songwriter Estelle, the show occasionally features other celebrity voice cameos. What if these singers are Gems from the Homeworld, in disguise? And if that's the case, wouldn't there potentially be many more?
