You know, the only two episodes I remember any Lucy appearances are the pilot (S1) and Metallo (S2). They were different actresses, and they were asked to behave in different ways by the script and by the respective directors, so I'd say you can describe her just about any way you want to. And if anyone calls you on it, you can just tell them that she went to the same plastic surgeon and the same personality transplant surgeon that Jimmy did after S1.
