Katherine's about to start a 10-month comedy tour, leaving husband Bobby in charge of a teenager, a 3-year-old and a toddler for a few days every week.

With the new school year starting, Katherine needs to help 15-year-old Violet focus, but a jaw-dropping act of teenage rebellion leads to an intervention.

Before Katherine takes to the road, she lays down the law between Bobby and Violet, and dashes off for an appearance on Vogue Williams' new podcast.

With her ten month long tour now in full swing, Katherine returns home to join Bobby for very intimate fertility tests and some shocking news.
