Despite the stories of lost romance that Percy has apparently been telling every goon he has hired or convinced to do his dirty work over the last 3.5 years, there was no romance. “Lisa” was his hired companion. An escort. A sex worker. She never saw him but he paid for her time (quite a bit, too). While he took up a lot of her free time with emails and phone calls, she overcame her annoyance and indulged him because he was a well-paying client.
But that’s all he was, a client. At the time, he was married. A client almost twice her age, unattractive in every way, overweight, balding, with a small, non-working penis. He had no sexual skills or abilities that she was able to discern. She preferred to avoid having sex with him as much as possible, to the point where he complains.
Still and all, she had affection for him, but he was never even within shouting distance of being among her favorite clients. Being completely annoying as well as terrible in bed kept him out of the running.
At this point, 3.5 years later, he is routinely referred to as “the client from hell.” That is, when “Rita” isn’t describing Percy Isgitt as a pusillanimous, fatuous gasbag; which phrasing “Lisa” also uses.
