This episode focuses on the precious relationships between family and friends that pull people through difficult times. Neil, who's 84, has fallen down the stairs at home. His wife Jenny reflects on the shock of realising that their life may never be the same again. Doctors become increasingly worried about damage to Neil's shoulder and an underlying heart condition. Meanwhile, his daughter Jane reveals how Neil carved out a long career as one of London's leading tree officers, and how proud she feels when she sees the trees he's saved and the legacy he's left for London. Danny, who's 25, has been knocked off his motorbike. Orthopaedic registrar Sadia is concerned about a serious leg fracture and that Danny may have other hidden internal injuries.
