There’s no confusion with Rosy and Roxy. They are very different people physically. And Medea is very distinctly recognizable, and not just for her tattoos.
But, you could show me a picture of Maiya and Mariya side by side and I wouldn’t be able to tell you which one is which. If they were by themselves in a picture, it would be even more difficult. They are very similar physically, have dark hair, etc. And, the almost identical names don’t make it any easier.
