Even after talking with the Princess, the King was unable to get clues about the real perpetrators behind Adeline's kidnapping because he never asked the right questions to the little girl.
He never asked questions like, "Who took you away from the garden?" or "Where did you go when Hawisa and Osanna went away from the garden?" And because of this, Queen Lillian was never mentioned in Adeline's story.
The King directly started his inquiry from questions like where she was and who Prince Theodore was. And after that his next question was "Who took you to the hill?"
And all Princess Adeline told him was that a nice man had taken her there. Adeline regarded General Osmond as a nice man because he had promised her to take her to her father and he had carried her, fed her, and took her to her new friend's home. Osmond had never assaulted her neither did anything to scare her.
