Hmmm. I read the Ruby not liking the name as it being very reductive - named after just a physical feature like that. Calling someone 'freckles' is unlikely to win you friends.Well, they’re all called “Amethyst” (just as all Rubies are “Ruby,” all Peridots are “Peridot,” etc.) The number designation is the actual individualizing element.
I wonder if Rubies even get that? The squad we’ve seen all seem happy to be called “Ruby,” and the one Steven calls “Eyeball” hates not being called by her name.
