Valerie, who's 63, is rushed to St George's after falling from a horse. Consultant Will is concerned about potential spinal and head injuries, and she's whisked off for an emergency CT scan. Valerie's daughter Vikki talks about how, with no father around and no brothers or sisters, her mum's been the one person who taught her about life: 'mum and dad rolled into one,' and her fears about losing her. Lisa, who's 66, may have damage to her prosthetic hip. Her husband Tony found her lying on the kitchen floor. Doctors send her for X-rays to find out if she'll need emergency surgery. Lisa reveals that she struggled with anxiety and agoraphobia as a young girl and how she spent a year and half in her bedroom.
