* Neil Perry: His intense desire to be an actor, coupled with his insecurities and the pressure from his father, could be seen as a form of jealousy towards those who seem to have more freedom or confidence. He feels the need to prove himself and seeks validation in ways that might be fueled by a feeling of inadequacy.
* Todd Anderson: He struggles with shyness and a lack of self-belief. While not directly jealous, he admires Neil's courage and charisma, which may be rooted in a desire for those qualities for himself.
* Charlie Dalton: His rebellious nature and disdain for authority could stem from a perceived lack of respect from his peers or a feeling of being overlooked. He uses humor and defiance to mask potential insecurities.
* Knox Overstreet: He is initially drawn to Chris, possibly out of admiration for her beauty and intelligence. However, his relationship with her could be fueled by a desire to prove himself or outdo other students, creating a competitive dynamic.
It's important to note that the film focuses more on the students' internal struggles and their search for self-discovery than on explicit jealousy. However, the themes of ambition, conformity, and pressure can be interpreted as creating an environment where competitive feelings might arise.
