Arms and the Man - S4.E10

The hours Kate is working in Whitby is putting a strain on her relationship with Nick. At the moment she is rarely at home except for weekends. Ron Cooper ends up in hospital from a breech explosion from his Lee Enfield .303 Army Riffle. Nick investigates as to why he had the gun in the first place and eventually finds hoards of old army ammunition at Cooper's farm. Greengrass has got hold of some grenades which he uses to clear Lord Ashfordly's river of most of his trout. Mrs Swinton thinks she's pregnant and Kate gives her some pills, which will determine whether she's pregnant or not by the next day. We later see Kate taking them, she tells James that she's pregnant, but she's less than pleased with the idea. She attempts to tell Nick but backs down.
