The other students, particularly those from wealthy families, initially view him with suspicion and disdain. David struggles to fit in, feeling the weight of their expectations and prejudices. His athletic talent in football earns him some respect, but underlying tensions about his identity and social status create a constant sense of unease.

David and Charlie Dillon start as friends, bonding over their shared experiences as athletes. Charlie, portrayed by Chris O'Donnell, initially supports David and admires his talent.
