but Hunter is nervous and hesitant about revealing the relationship to Michael and Ben who still assume Hunter is gay. When Hunter does tell Ben and Michael the truth, the two are initially surprised but express their support nonetheless. Hunter is forced to admit to Callie that he's HIV positive prior to the two engaging in sex. However, Callie appears non-perturbed and calmly advises him to use a condom. Callie's parents, while initially supportive of the relationship, are shocked to learn of Hunter's HIV status when they read Callie's diary. Having previously arranged to meet Ben and Michael for a cordial dinner, Callie's parents instead use the opportunity to confront Ben and Michael with their discovery and forbid the relationship to continue. The Leesons further demand to know how Hunter contracted HIV. Ben and Michael refuse to answer, but Hunter, overhearing the conversation, angrily reveals his history as a prostitute. This revelation shocks Callie enough to break off the relationship herself the next day at school. Although no longer dating Hunter, Callie remains supportive and sympathetic and even stands up for Hunter when he is bullied at school after his HIV status is leaked to the student body. She further denounces her parents’ hypocrisy after they and other concerned parents try to pressure Hunter into withdrawing from school. Hunter misinterprets Callie's support as an invitation to resume their relationship and is dismayed when he learns that Callie has started seeing someone else. The pain and regret of losing Callie contributes to Hunter's decision to leave Pittsburgh.
