This episode focuses on the strong bonds within families and the challenge of breaking bad news. Bill, who's 92, arrives at King's with breathing difficulties and a swollen leg. He's accompanied by his stepdaughter Jo. As he's treated, doctors suspect the shortness of breath and swelling could be due to a clot and send him for X-rays. But the test results suggest there may be something more serious wrong. Meanwhile, Bill talks about reaching his nineties and his strong bond with his stepdaughter. Andy comes into King's with stomach cramps. The 45-year-old had a liver transplant 10 years ago and, as doctors investigate the cause of his discomfort, Andy reflects on living with someone else's liver, growing up in the East End, his time as a punk living in a squat in Waterloo and his career with the Royal Navy. Sarah, who's 25, has been finding it hard to stand up and has been brought into King's by her mum and grandfather. Sarah has learning difficulties as a result of an inherited genetic disorder. Her dad died from the same condition when she was just seven. As her symptoms deteriorate, doctors are concerned she may have suffered a stroke. Sarah's grandfather Clive is by her side throughout. He reflects on his strong bond with Sarah and their mutual love of Charlton Athletic.
