When Caroline's mother visits, Annie becomes upset at the blandness of their relationship and encourages Caroline to have a healthy fight as she and Angie do. When Caroline timidly tries to open up to her mom, Margaret repostes with a real shocker: she hates Caroline's comic strip. Meanwhile, Del and Charlie go to Atlantic City at the request of a potential investor, and Richard tags along for the free ride, desperately trying to finish the new John Grisham thriller while resisting everyone's determination to tell him the surprise ending.

Caroline and the gang visit her family's home in Wisconsin and learn her parents are selling the house. Distraught, she prolongs her stay (while Richard unwillingly bonds with the locals), and ultimately decides to preserve her childhood memories by buying the house herself.

After deciding they can't wait to get married, Caroline and Richard plan their nuptials for the following week. But while Caroline and Annie search for the perfect wedding dress, Richard shows up at the bridal shop with a bombshell announcement regarding his ex-wife: Julia has given birth to their son. Caroline gets an unexpected visit from Randy; and Annie and Del flirt with the idea of having a no-strings-attached fling.
