Ruby and Emerald are both names for gemstones. They must be sisters. Summer and Winter are sisters too! Neptune and Mercury are cousins! Fox and Dove are both named for animals, Nora, Ren, and Sage all named for flowering plants. Lie Ren and Yatsuhashi have East Asian names as well, surely the're related to Yang, Yue, and Taiyang as well, yes?

Another good reason to advocate for Yue is that, while we cannot disprove the existence of a character named Raven in the show, we can prove the existence of a character named Yue thanks to Monty's Tweeted image of his computer.
