Who is Kimberley Wilder from Hocus Pocus and what is their importance?

Kimberley is Jason's daugher. She is a student at Tarkington College, who agrees to wear an audio recording device so that her father can gather evidence of Eugene's "radical" nature. Kimberley does exactly what her father tells her, baiting Eugene with highly charged questions, which in turn, force him to give her honest if unconventional answers. The audio recordings will later be edited to use against him.
