How does Jo want the story to end and why?

Jo wants the story to end on a note where the old Wizard hits Mommy Skunk hard on her head and refuses to get Roger back to his original smell.

She wants this to happen because she cannot see Roger Skunk being left alone by his friends. According to her Roger is perfect in smelling like roses and that his friends won’t run away from him anymore. She doesn’t understand the purpose behind Mommy Skunk’s eagerness to her little roger back to smelling foul.
