Treading Carefully - S4.E11

Nick and Kate's relationship is really put to the test. Nick is slacking in his work, whilst James that her quality of work has also reduced. Nick confides in Blaketon and James is there for Kate to talk to about their problems. Kate tells Nick she is pregnant but he is a lot more keen than she is and is upset when she suggests bringing up the baby on her own, because of their ‘unworkable marriage'. Kate ends up performing first aid on top of a church roof, and Nick is annoyed at her for taking the risk going up there, but she informs him simply that its ‘her job'. Later the situation is reversed when Nick arrests a man with a knife. In the final scene Kate tearfully realises the baby and their marriage is most important and is upset to think she may have ruined her and Nick's special time, but Nick comforts her, telling her everything will be all right and the couple make up happily.
