Edie decides to move out as she is tired of the neighbors' cold attitude towards her, especially Karen McCluskey who insulted her with a crude joke earlier. When she asks Dave why he insists on staying in Wisteria Lane, he avoids the question by saying that they can be happy here and convinces her to stay. The next day, Dave pays Mrs. McCluskey a visit and demands an apology to Edie. Karen refuses, as she believes she was merely joking and claims Dave doesn't know her well. Dave then tells her that Karen must be lonely when he notices she talks to her pet cat Toby like a person and invites him in without hesitation. Toby goes missing after that and Dave offers to help her find the cat on condition that she apologize to Edie. Karen finally does, and tells Edie to inform Dave that they have reconciled. Later, she finds Toby back in her house, and finds her front window is left open. Karen ponders about Dave's true motives and teams up with Katherine to learn more about him.
