Mack is attempting to tidy things up at his stall, but Molly has been distracted by a funny poetry book. Meanwhile, Moira brings two new arrivals to the Kids Club for the first time – her granddaughter Caitlin and Caitlin's best friend Euan. Everyone is very excited to meet them and they immediately set about building a cool spy den for all the children at the Kids Club.
As Caitlin takes charge, people notice how like her Granny she is. However, Moira is offended that people think Caitlin is nosy and bossy like her! Can Molly the poet find a way to help the grown-ups make it up to Moira?
