In a continuation of the very first episode, a couple face up to the harsh realities of living with Alzheimer's. Mac gets involved when Derek turns up at the surgery. Jo is upset with Ross.
Dr. 'Mac' McGuire warns Margaret Richmond that her daily trips to her husband Derek's care home will probably lead to her exhaustion and warns her to slacken off. She does not listen and ends up crashing her car, meaning that she will not be able to see Derek for a while.—don @ minifie-1
