So I have a theory regarding Leslie's missing wife. My theory is, the woman in question is Elena of the turks. This is because in the original game, Don Corneo's return when the party go to Wutai involve him kidnapping Elena (and Yuffie). So, I just think that this would tie in well with Leslie getting his revenge on Don Corneo.

Sure, we see Leslie's wife in a flashback scene, but it still could be Elena IMO, she could have changed her look when she joined the turks. Also explains her disappearance.

What do you think?
