Why does jack insist that it …

Jo's insistence that the wizard should hit mommy, angered Jack. Jack insisted that it was the wizard that was hit and not, the mother because every time Jack created a story, he laced it with some autobiographical details. Roger Skunk's insult was out of his own childhood—he remembered 'certain humiliations' of his own. Jack felt he was telling her 'something true, something she must know'. Thus, when Roger Skunk's mommy found the smell of roses awful, she took him back to the wizard. She hit the wizard right over the head with an umbrella and made him change his smell to the original one. When Jo insisted the wizard hit mommy, Jack retorted sharply. With 'rare emphasis' Jack defended the mommy as if 'he was defending his own mother to her. He was not witling to alter the end and insisted that the little skunk loved his mommy more than he loved all the other little animals and she knew what was right for him.
