Did Rhett ever come back to Scarlett? One example of a good open ending where the reader can speculate. The Pilot's Wife, not so much. Too many weak open ended questions, such as why in the world would Jack lie about his mother being deceased? Why did he not divorce his wife? (He could have cared for Mattie in spite of a divorce) Why did he not make provision for his Irish family? Too wishy washy for satisfaction.
