Fiona visits Karen (Meg Ryan) and performs therapy there in an effort to uncover evidence that may clear her name; and she hatches a plan to silence Robin for good. Meanwhile, Robin reveals that she recorded some incriminating video.
Against Fiona's wishes, a pair of long-distance lovers take a significant step to resolve their issues. Meanwhile, Fiona takes on a new client who is a compulsive gambler (Matt LeBlanc); and she receives a puzzling video voice mail from a woman (Chelsea Handler) who seems to know her.
Fiona's mother calls to check on Kip; compulsive gambler Nick discovers that his therapist is his online gambling nemesis; Austen announces that his baby is on the way; Fiona's plans for Sylvie backfire; the mystery woman from the voice mails calls again and reveals intimate knowledge of all things Fiona.
