Overview
Nina Campbell is a teacher's aide as well as a student at Pendelton State University in Rutherford, Ohio. She works for Doctor Mary Albright, who unfortunately, shares an office with the eccentric Dick Solomon. Nina was unaware of Dick's true nature, which included being an alien from another planet. Dick would often consult with Nina on affairs of the heart, but generally dismissed whatever advice she would give him in favor of his own opinion. Nina often grew frustrated with Dick's behavior and has voiced her own concerns about him on more than one occasion.
