Cuddy and House collapse on the bed, naked and sweaty and breathing hard. So were they having sex while hovering in the air above the bed? Standing up on the bed? That can't be good for House's leg. Cuddy totally ruins (or possibly enhances) their post-coital bliss by asking House why he didn't let Wilson in the apartment. "You were thinking about Wilson while we were having sex? That's so cool! So was I," House responds. Huh. But while House may have been thinking about Wilson's body, Cuddy was thinking about House's motivation not to let Wilson in. "You were hiding me from him. Why?" Cuddy demands. House says he was simply "protecting [Cuddy's] privacy." This from the guy who once announced to the entire PPTH lobby that he was having sex with her. "Why would we be doing all this if I wanted to be private?" she says. Um ... because it's more fun that way? Oh, and because everyone at PPTH will surely think less of Cuddy for dating an asshole like House? Or maybe because someone is bound to call children's services just in case House comes anywhere near Cuddy's child? How about the fact that, as of yesterday, Cuddy was engaged to another man? There are so many reasons. Then it occurs to Cuddy that perhaps House isn't ready to go public about being with her.
