Katie and Greg are thrilled when Anna-Kat finally has a playdate with a "normal" girl. But Anna-Kat has a little secret: She's a budding kleptomaniac and has taken something from her new friend Penny's home. Greg wants her to return the item and fess up, but Katie disagrees, especially since Penny's mom, Chloe Brown Mueller, is one of Westport's most infamous gossips.

Greg befriends fellow history buff Stan, but Katie is less than pleased, especially considering he is married to her nemesis, Chloe Brown Mueller.
