Jeremiah and Conrad (Situational Irony)
Whereas Jeremiah is consistently kind, patient, and friendly towards Belly, Conrad is hot and cold—at times making her feel special, and at times making her feel like a petulant child. In this summer in particular, Conrad displays a mix of aggression and tenderness to Belly that both confuses and excites her. Ironically, it is not the consistently kind Jeremiah, but the conditionally friendly Conrad that Belly falls in love with.
Jeremiah's Sarcasm (Verbal Irony)
While playing Truth or Dare with Taylor, Belly, Steven, and Belly, Jeremiah playfully chides Taylor about using the word 'gay': "Well, 'gay' doesn't mean 'lame,' Taylor, now does it?" Jeremiah said. He spoke in a sarcastic tone, but even mean attention was better than no attention. Probably he was just mad about all the attention she'd been giving Conrad that day." Jeremiah's statement counts as verbal irony in that though it is literally a chide, it is actually intended to mean something else.
Being with Cam (Situational Irony)
In various instances, Cam and Belly simply don't seem to "get" each other. For example, while at the beach, Belly (seriously) insists on eating the last Fruit Roll Up. Thinking she's joking, Cam eats it. Then, after eating it, he offers to get Belly a drink, but rather than getting her the Kool-Aid he requested, he adamantly refuses: "'I'll bring you water, not Kool-Aid.'" The two share rather different worldviews, yet continue to see each other over the course of the summer. Belly's interactions with Cam serve as an ironic contrast to her easy, comfortable interactions with, for example, Susannah, Jeremiah, and at times, Conrad.
Steven's Departure (Situational Irony)
While Belly bemoans not being able to be part of the crew when Steven is around—because he tends to want to exclude her—when it comes time for him to leave Cousins Beach, she finds herself ironically wishing that he would stay. While Steven's departure from Cousins would guarantee her more time to hang out with Jeremiah and Conrad (and it does), she fears the possibility that Steven's departure may irrevocably change the interactions that have governed her relationships with the Fisher boys since childhood.
