Elizabeth was a woman who came to work at D&D Advertising and was the assistant of Billy Campbell. He was initially attracted to her because she reminded him of a younger Alison Parker. He confided in her with his feelings after Jake Hanson went missing in the ocean after a boat explosion.
Alison was jealous of Elizabeth because Billy liked her and used some of the same lines on her that he used on her.
After she refused to do her job for Alison, Alison lodged a complaint with Amanda Woodward, at which point Elizabeth was fired.
