Sonja

Sonja was Uncle Gary's fourth wife. She appears in the fifth book, Diary of a Wimpy Kid: The Ugly Truth. She and Gary were on a date at a baseball game, when a plane flew overhead carrying a banner reading "Marry me Sonja?". She says 'yes', thinking it was for her, but it was for another Sonja. She and Gary most likely divorced after learning the truth at their wedding party.
