* Paul's blindness: This is the most obvious and central irony of the novel. Paul's literal blindness to the world around him makes him acutely aware of the figurative blindness of others. They fail to see the truth of the situation at Lake Windsor Downs, the real reason for Erik's bullying, and the actual danger that surrounds them.
* Erik's "superhero" image: Erik Fisher, the seemingly popular and powerful athlete, is actually a deeply insecure and troubled boy. He uses violence and intimidation to mask his vulnerabilities. His facade of strength ironically hides his true weakness.
* The "perfect" community: The seemingly idyllic community of Lake Windsor Downs is plagued by corruption, violence, and a lack of accountability. The "perfection" they strive for is a façade that masks the darkness beneath the surface.
* The football team's victory: The football team's victory is celebrated as a triumph, but it comes at a high cost. The team is built on lies and manipulation, and the victory is ultimately hollow. The true cost of this "success" is not acknowledged, highlighting the irony of celebrating such a shallow achievement.
* The "justice" system: The justice system, which is supposed to protect and uphold the law, fails to address the serious issues at Lake Windsor Downs. This ironically highlights the inadequacy of the system and the failure to truly protect the innocent.
Overall, the irony in "Tangerine" serves to highlight the contrast between appearances and reality. The novel exposes the hypocrisy and the darkness that often lie beneath the surface of seemingly perfect communities. This irony forces the reader to question the values and assumptions of society and to confront the consequences of blind acceptance.
