Katherine is introduced as the woman who interviews Annie Wilson at the Abbott Playhouse for an internship. Although Annie purposely blows the interview by revealing she was involved in a hit-and-run, Katherine respected her honesty and offered her the internship, though she had some ulterior motives.

She soon began complimenting Annie on her body, looks, and good looks, making Annie think she has a crush on her.
