This episode focuses on the bond between families and what holds them together through thick and thin. John, who's 84, is rushed to St George's after losing control of his car and crashing into a road sign. He bullseyed his windscreen, and when his blood pressure drops dangerously low doctors declare a Code Red, giving him an emergency blood transfusion. As doctors discover that John has a broken pelvis and will need emergency surgery, his wife Gwynaeth talks about how she's leaned on John over their years of marriage: 'I don't think I know anyone else who I could rely on who could get me over the humps.' Reggie, who's seven, has broken his arm while doing a cartwheel to celebrate England beating Wales at Euro 2016.
