While making Claire's bed, Jay finds her diary. Of course she reads it, and that leads to a mother-daughter talk about sex. Meanwhile, Jr. takes an unofficial driving test when he takes Michael to an eye-doctor appointment. And all Kady wants to do is play hide-and-seek.

Tennis star Serena Williams guests as a teacher in an episode in which Jay volunteers to direct Kady's kindergarten-class play ("Romeo and Juliet"), and volunteers Michael to help her. But Jay, who has a very competitive side, doesn't want anyone to stand in the way of her "vision." And she treats her charges as though they were army recruits and she was a drill sergeant.
