 This is especially evident in Series 3 where every character has at least one subplot revolving around the issue.Chief among these is the series-long arc in which Ruth and Anthony try to conceive a child non-sexually — he because his relationship with his naturally-conceived daughter has fallen into ruin, and she because of an inability to sustain a meaningful romantic relationship with a man.Because of the inclusion of several recurring characters who are not practicing pathologists, but rather administrative or laboratory staff, the programme can also be classed as an office comedy in the vein of the television programmes, "30 Rock", "The Thin Blue Line" and "NewsRadio".
