When Vivian discovers that Ethan is a Jew, albeit 'non-practicing', she gets him to agree to convert to catholicism so she can have her church wedding, but he realizes he can't give up his entire identity for a woman he doesn't even really love and cancels the marriage. Libby is grateful to Ethan for resuming her fertility treatment, but when the initially secret pregnancy comes to William's ears, he's furious at both. The sex study becomes ever bolder, involving both 'researchers' ever more physically, yet she refuses to be paid like other subjects, while even their eager secretary changes her mind about being filmed.
