Wil's Escape
When Wil finally reaches his girlfriend's car, he thinks he is safe. Ironically, just at that moment, he realizes that he led his persecutors straight to her, so even if "it had been so hard to get here, [...] now he had to run again."
Schools
Soon after Emily has arrived at the Academy, she tells Charlotte that this building does not look like a school because of its splendor, which is the opposite of what she has expected. However, Charlotte opens Emily's eyes by saying that the schools she may be used to are more like child farms than schools, whereas the Academy is a place which actually helps its students to reach their potential.
Jeremy's Dream
When Jeremy was a child, his family had two chickens, one of which was insane. Jeremy's dream was to become a zookeeper because he liked animals very much. He even "imagined this chicken becoming his friend, and people saying, 'Jeremy’s the only one who can go near that chicken.'" Ironically, this never happened because "one day the chicken attacked him, pecking his face, and his father wrung its neck."
Campbell
Just before Campbell goes into Broken Hill, he tells Eliot "That stuff is old school. Obsolete. And you older guys, if you don’t watch out, you’ll be obsolete with it." Ironically, it is Campbell who is killed shortly after, becoming obsolete, while Eliot survives the trip to Broken Hill.
Dramatic Irony in News Clippings
The story is interspersed with clippings of news reports, which retell the story from an outsider's perspective. They are an example of dramatic irony because by the time the readers read them, they are already familiar with the actual events. Most of the time, the news clippings fail to connect all the dots; for example, when Wil's movements through the airport are described as "an earlier disturbance in which a man ran through the Arrivals hall in an agitated state, initially thought to be connected to the shooting, [...] found to be unrelated," when the reader knows full well that he was part of it.
