Chapters 11-24 Analysis

Cassie’s characterization changes in significant ways in this section of the novel, as she grows more insecure about her relationship with Joel and paranoid about her past. Cassie’s insecurity about her relationship with Joel stems from the nearly 10-year difference in their ages. The first time they meet Cassie, Joel’s friends—especially Lydia—make comments about Cassie’s relative youth. When Lydia’s daughter Violet notices a physical similarity between Cassie and Joel’s ex-girlfriend Francesca, Lydia dismisses her, saying that Cassie is “much younger than Francesca” (99). Later, when Lydia’s husband Pete refers to Cassie as Joel’s “new woman” (100), Lydia “Lydia corrects him under her breath” (100), calling Cassie a “girl” (100). Lydia’s strong reaction to the difference in Cassie and Joel’s ages causes Cassie to feel insecure in her new relationship, wondering if Joel is “ashamed that he’s dating a girl ten years younger than him” (100). Lydia’s unkind comment foreshadows her later attempt to murder Cassie—she feels affronted on Francesca’s behalf, believing that Joel has thrown her over for a much younger woman. It also highlights the significant power differential between Cassie and Joel: He and his friends are older, more established, and far wealthier than Cassie, and Cassie must contend with The Disempowering Effects of Wealth Inequality as she navigates this new relationship.


Cassie’s insecurities are amplified when she attends a Halloween party at Lydia’s house. Although she knows that “when you go to a party with people ten years older than you, it doesn’t look good to put on your sexiest, sluttiest outfit” (149), Cassie allows her friend Zoe to design her costume and do her makeup. Joel reacts coldly to the costume and avoids Cassie throughout the party, causing her to wonder if her “dress is a little too smoking hot” (161). As Cassie chastises herself for wearing a sexy costume, her doubts are explicitly centered on the differences in their ages: “[S]he’s not going to a college party. She’s going to be with a bunch of professionals a decade older than she is” (161). Cassie’s growing insecurities about her age gap with Joel complicate their relationship moving forward. Because she is a newcomer to this tight-knit group of friends, Cassie misreads Joel’s reaction. He is upset not because Cassie’s costume is too sexy but because it is a nearly exact duplicate of a costume previously worn by Francesca: Lydia deliberately set Cassie up by encouraging her to wear this costume without telling her about its history. This act of bullying suggests that The Insidious Nature of Jealousy extends even beyond those directly affected, as Lydia takes on the role of avenging and protecting her deceased friend against a romantic rival.


This section of The Ex also changes Cassie’s characterization as it hints at a criminal past that she is hiding from both her employee Zoe and her boyfriend Joel. When Cassie’s apartment is vandalized, she is hesitant to call the police because she knows that “if the police come, they’ll want to go into her apartment” (130). Cassie worries that if police enter her apartment, “they might find what Grandpa Marv left behind […] and that would lead to questions Cassie can’t answer” (130). These oblique references aim to create mystery around Cassie’s character. The fact that Cassie is unwilling to report targeted vandalism at her home suggests that she has something significant to hide.


Later, further details deepen this mystery. Cassie freezes when a police officer enters the bookstore she owns. Cassie’s shoulders “sag in relief” when she realizes that the officer is “not here to take her away” (151). Cassie’s physical reaction to police presence reflects her deep-seated anxiety that one day officers “will be coming here with a warrant for her arrest” (151). Although Cassie’s criminal activities are not detailed at this point in the novel, there are certain clues about the nature of her crimes. When Zoe suggests that the bookstore open “an erotic literature section” (159), Cassie knows that her grandparents would be horrified at the idea. However, she privately acknowledges “it’s certainly not the worst thing that’s been done to keep Bookland afloat” (159). This scene suggests that Cassie’s crimes are related to her work at the bookstore. Later, when considering who might have vandalized the bookstore and her home, Cassie first assumes it is Joel’s ex, but then realizes that “there are other people who have good reason to lash out at her” (139). This suggests that Cassie’s crimes are not victimless, but directly affect other people.


The setting of New York City is an important part of the novel, and these chapters depict the city as having the feel of a small town despite being a crowded metropolis. While on a date at the Central Park Zoo, Cassie and Joel unexpectedly run into his couple friends Pete and Lydia and Con and Anna. Later, the Ex unexpectedly encounters Joel’s new girlfriend, whom she has nicknamed “Olive” at a random Starbucks far from either of their homes. As Cassie becomes obsessed with Joel’s ex-girlfriend Francesca, she realizes that Francesca’s restaurant is near her bookstore. She walks by on her way home. These chance encounters help to characterize New York City as a small town where the likelihood of running into familiar people is high.
