Jane and Michael follow Mary Poppins on her day off, to Heaven, and they meet the boy Jesus, who is still slightly scared of Mary Poppins because she was once his nanny, and the Holy Ghost, who complains that he has not been able to get his sheet properly white since Mary Poppins left, and God the Father, who says, “There’s no making her do anything. Not her. She’s Mary Poppins.”
