Plot summary
Virginia has trouble telling Bill that she cannot accept his proposal, but Bill informs her that Scully has cancelled the study because he found out they were monitoring couples having sex. Bill believes it was Ethan who told Scully and fires Virginia on the spot for sleeping with him. Bill moves the study to a brothel with the help of Betty, but he and the participating prostitutes are arrested shortly after. Meanwhile, after being rejected by Virginia, Ethan tries to replicate their sexual liaison with other girls, but to no avail. Virginia coaxes some reluctant prostitutes to rejoin the study, and Bill temporarily takes her back to work with him, but refuses to commit beyond the day-to-day.
