How does the author use verbal irony in the novel, Ace Hits the Big Time?

The authors use a narrative technique of interior monologue that records Ace's thoughts, memories, and feelings. This reveals Ace's depth of character, as well as his verbal irony. Readers hear Ace think something that differs from what he says. For example, when Raven says "I can't wait to hear what you tell the Falcons" after they request that Ace join the gang, Ace tells Raven "Neither can I" yet wonders, "What am I going to tell them?" Readers hear him describe himself in Latin as "non compos mentisl i.e., out of it. Mentally deficient...i.e., ME!" as he describes his state of mind.
