I got a theory. On the new translated scans (thanks to bittermeat), the picture of the "Mystery Girl" looks like Aqua. But just because she looks like Aqua, doesn't mean she is Aqua! Just like Roxas and Ven! And the "Mystery Girl" could be the 14th member, but she dies in KH:358/2 Days, so there's no proof of her existence in KH1, and KH2. Any Comments?
