Tetra is Zelda in the same sense that Shiek is also Zelda, but reversed whereas in OoT Zelda turned into Shiek, Tetra turned into Zelda (or at least had her clothes magically change). If it helps, think of her like a long lost heir to Hyrule, being royalty is something that she was born into even if she didn't know it herself. She was raised as a pirate, therefore she is a pirate who happens to be a princess.
And everyone knows that Tetra prefers pumpkin soup.
