In the original Japanese version, Molly's (Mi's) mother's disappearance is not addressed on-screen. When the Japanese filmmakers were asked about this, they provided a detailed story about her and her absence. So Molly's mother is shown in the American version as a Pokémon researcher, like her husband, and her disappearance is explained early in the movie. The film's final credit sequence was re-edited so that the American audiences would be sure to see the return of Molly's mother and father, which is only shown in the Japanese version at the end of the final credits.
