House limps into Cuddy's office, takes one look at her face and her body language, and decides not to take Wilson's advice. "You know," he says. Cuddy says she does. "Oh, thank god," House says, which is probably not the response Cuddy was hoping for but he just can't help but love it when his suspicions are proven to be correct. Cuddy says she's waiting for an apology, but House doesn't think he did anything wrong. He was just doing his job and lying to Cuddy saved his patient's life. And he lied to her at work and not in their personal life, so it's different. Not to Cuddy, it isn't. "You don't get to lie to me about anything," she says, which is a lot different from before when she was saying she didn't want House to change and stuff. "I can't compartmentalize my life like that," she says. Great, then DON'T DATE AN EMPLOYEE. Idiot. Anyway, House isn't going to apologize and Cuddy's just going to have a sulk until he does.
Ultimately, Taub doesn't have to tap all of Julie's joints as he spots a big smallpox-looking rash on her knee. Too bad for Julie that he didn't spot that before he tapped all her other joints. Also too bad for Julie that she has smallpox. While the Cottages wait for the CDC to arrive and take over, they put on their spacesuits and examine Julie's body for more pox. Julie whines that she's going to die. House tells her to not to be so hasty -- smallpox is only 30% fatal. Unless they find evidence of hemorrhagic smallpox, in which case Julie's pretty much dead. Martha finds another rash in Julie's armpit that House describes as a "regular rash," which somehow means it's not smallpox after all.
