 Ling is the only major character in "Ally McBeal" who does not have a story for the origin of her particular neurosis.She is exempt from the psychoanalytic focus given to others in the series, which Smith attributes to her Asian "mysteriousness".Woo is cast as a villain, underscored by her frequent appearance to the theme music that accompanied the Wicked Witch of the West in the "Wizard of Oz".
