She locates and then yells at Greg, as Greg went to the Expo without his mother's permission, and then makes Greg leave the Expo, stating he should put the Diaper Hands business behind him. It is then that everyone realizes Greg is Diaper Hands from the viral videos and trends, When Susan reveals that Greg is Diaper Hands, he and the audience chant, "Diaper Hands! Greg Heffley!" Digby is not seen again for the rest of the film.
