Carter and Abby examine CC, who's sporting a nice raspberry on his cheek. "He's got it, doesn't he?" he asks mournfully. "Dimon -- he's got the High Five." Abby doesn't understand this strange hip lingo. "HIV," clarifies CC. Carter cites doctor-patient confidentiality, but does ask if Dimon is aware of CC's condition. CC nods. "But my viral load's been zero, and he only gives," CC explains. "I told him, 'Wear a rubber anyway!' He said, 'What for?' It wasn't sex to him." Carter's jaw drops slightly. He and Abby simultaneously realize that CC wasn't sleeping with Aisha after all. They're twenty minutes behind the rest of the world on that one. "He's on the DL," spits CC. Carter and Abby have no idea what that means. "Down-low," CC clarifies. "See, he ain't gay. He can't be a faggot and be legit. He only does guys because women get so stressful." The last sentence is tinged with bitterness. Carter begs him to try to get Aisha's pager number so that she can return and get tested. His face cloudy as Dimon's urine, CC agrees.
Outside the room, Carter tells Abby that he's off to lunch with his father, and that she should page him when CC gets Aisha's number. "So, 'down-low' is 'bisexual'?" Abby asks, puzzled. "No, 'on the side; in secret,'" Webster Carter replies. "In the closet?" she tries to clarify. "No -- to be in the closet, you have to be gay," Carter explains. Abby shakes her head. "He is gay," she points out. "No, he's on the down-low," Carter says with a snicker. Abby sighs. "If he's having anal sex with his friend, he's gay," she rationalizes patiently. That's my favorite line of the episode, heightened by the absolute matter-of-fact delivery. Carter repeats that the anal sex is just for release. "So 'down-low' means 'in denial'?" Abby giggles. Carter laughs too. That whole bit was entertaining, actually.
