to inquire about his squawking condition again. House initially diagnoses it as acid reflux causing his vocal cords to tense, but when Schwartz adjusts his belt due to soreness, House realizes Schwartz has pancreatic cancer, which was the root cause of the acid reflux. At the same time, it is reported that the patient with alien hand syndrome, Scott, is really suffering from a reaction to an ingredient in the industrial-strength antiperspirant he uses. House then goes to talk to Cuddy in her office, and asks her if she could possibly be overreacting to the previous night. She finally admits that maybe she is, since he's "said plenty of lousy things to [her] before." House seems confused, as he assumed that she was overreacting to her and House having sex and what it could mean to their employer-employee relationship. But he realizes that Cuddy's reactions all day have been consistent, and in fact it is his own memory of the situation that is faulty. He turns his attention to the lipstick Cuddy left at his apartment, which he has been playing with all day, and is troubled that Cuddy's coffee cup shows no lipstick smears; his memory of the prior evening included smears of lipstick on his face from kissing Cuddy, so he expects her lipstick is the sort that smears. He asks Cuddy whether she has another type of lipstick, one with a "sealing agent", that might explain the discrepancy between his memory of the smeared kiss and the reality that now confronts him of the unsmeared coffee cup. House then has a flashback to the night (from the episode "Under My Skin") before when he thought he told Cuddy that he needed her help with his addiction. He suddenly sees the reality of what has happened: he never told Cuddy he was having hallucinations that night. His final words of the evening were: "You can go suckle the little bastard child if that makes you feel good about yourself." Upset by this remark, she left the office and went home, never accompanying him to his apartment. House snaps back to reality and tries to explain to Cuddy that that's not what actually happened, saying "I told you I needed you, and you helped me." He reaches into his pocket to remove the lipstick, but, to his shock, he discovers that it is actually a bottle of Oxycodone. He
