What exactly are you trying to say? That Anjean and Tetra look a lot alike? If not please give better clarification on the topic. Truthfully, it would help to better know what you want to discuss before we start out on random assumptions.
Well, they look alike, I'll give you that. But are you implying that Tetra and Anjean are the same person? Well, that's interesting, but that's not possible. Even Anjean mentioned that she met Zelda's ancestors. But who knows.
I...can't see this discussion moving anywhere. Anjean and Tetra are in no way the same person. Anjean is a Lokomo, immortal as a servant race to the Goddesses, and she tells Zelda that she was good friends with Tetra back when New Hyrule was first founded.
