So Ziggy’s in for a shock when she enters restaurant Salt and discovers Simone is back, back, back and hasn’t moved to the city after all! To cover the fact he has started a secret affair with Simone, Brody quickly lies that Simone is working at Salt until she can find another job to go to in the city. But will his wife see through his lies?

Later that day, the marathon gets underway with Maggie, daughters Ziggy and Coco and family friend Leah Patterson all competing.
