When you watch Masters of Sex Season 4 Episode 8, you'll see Bill and Virginia go undercover at a rival clinic. Dody stops by Bill's motel room, and she reveals she never got his proposal letter, but she would have said yes. Virginia finds out about Dody's visit, and questions Bill. Later on, they have sex for the doctors they are investigating and Virginia tells Bill she loves him. Nancy and Art are approached by Mr. Clavermore about the possibility of expanding the clinic to New York where they could run it. Nancy uses the information Virginia told her about Art and manipulates him into considering it when she lies and says she doesn't want to swing anymore. Austin tells Guy he should partake in the sex study, but Lester urges him not to. Libby considers going to school.
