P.C. Joe Penhale (John Marquez) has an unexpected visitor - his ex-wife Maggie (Julie Graham). She appears to have completely forgotten that they split up a couple of years ago. When he tries to tell her they are no longer married she accuses him of over-reacting, and wants to know why he packed his bags and left her. Joe struggles with a mixture of distress and elation at seeing Maggie again. He has thought about her every day since they parted. He realizes she is clearly not well, and tries discreetly to ask Dr. Ellingham about her symptoms without telling him that he is talking about his ex-wife. Meanwhile, Martin and Louisa's baby still doesn't have a name, and P. C. Penhale warns them that time is running out. If they don't register a name for the baby soon the State will step in and name the baby. After protracted discussions the couple finally reaches an agreement.
