S09E13 — The Fine Art of Parenting

When new mom Lucy welcomes guests over to see the baby, Annie immediately becomes concerned, believing that Lucy doesn't fully understand the health risks of exposing a newborn to strangers. Lucy's determination to show everyone that she has parenting under control leaves Kevin to question his role as a father, especially when they're alone. Also, struggling new parents Kevin and Lucy move back into the Camden home, while Martin moves into the garage apartment. Eric is worried that he and Annie are doing too much in helping Kevin and Lucy adjusting to parenthood as they're taking on more than they should as grandparents. Meanwhile, Martin's classmate Zoe (guest-star Katie Cassidy) intentionally falls asleep on the couch of his apartment so that she can tell everyone at school that they slept together. When Ruthie finds out about Martin's overnight guest she sees it as the perfect opportunity to blackmail him into getting her a date with her crush, Vincent (guest-star Thomas Dekker).
