Yeah, I guess Daniel's right... As much as I love the name "Nadia," even King Guardia called her Marle in one of the endings. (I've always tended to think it was a mistake though.) I believe it was the ending where Crono is dead, and Epoch is not destroyed. (The king hangs Nadia's Bell instead of letting her do it, and when he is left hanging, he says "Marle? Where did you go?")
