This episode explores the importance of friendships for both staff and patients in A&E. David, who's 23, is brought to King's after having seizures uncontrollably for 30 minutes. He was found on the floor at home by his housemate Mike, who has accompanied him to hospital. This is David's second trip to A&E in a fortnight due to his epilepsy. 'If someone doesn't stop to fit after half an hour, we will become very concerned,' says Dr Ling. 'Brain damage is a concern, so there's a pressure to get on top of the situation quickly.' David isn't responding to drugs so Ling weighs up the benefits of putting him into an induced coma to stop the seizures. Meanwhile, 49-year-old Suzette and her grandson Azario have come to King's after Suzette was knocked over by a cyclist. While Suzette waits to be seen, four-year-old Azario races around A&E on his scooter, reminding visitors and patients to wash their hands. And best friends Selin and Maria have come to King's after Selin cut her hand while taking the stone out of an avocado. While Selin has her finger stitched up by Dr Ling, she and Maria discuss what friendship means to them.
