House arrives at Cuddy's house for dinner early, all the better to sneak off and play with Rachel while Cuddy finishes making the food. Cuddy doesn't find House's desire to spend time with her daughter at all suspicious because she is stupid now, and once inside Rachel's room, House grabs a bag of toys he was hiding beneath her windowsill that are identical to the ones in the preschool playroom. Rachel isn't interested in playing with the new toys, and House mutters that she is a moron. Yeah, that won't traumatize her or anything. Cuddy is insane for leaving House alone with her daughter. House knocks Rachel's block tower over and shoves her old toys away, which is just mean, and tries again to get her interested in the preschool toys. She tries to eat one of them.
Chase arrives at who I'm assuming is the shortest of the three's apartment. She's surprised to see him, then worried that he's here to tell her he gave her herpes or something. He immediately accuses her of taking the naked picture, which she claims to know nothing about, forcing him to show it to her. It also gives him a glimpse of her living room, which is all pink and full of hearts and kittens in a way no sane adult would possibly decorate. She informs us that the picture of Chase has indeed been altered, but says she didn't take it. And she wasn't even the right height to take that picture since she was wearing high heels the entire time she and Chase were together. And she wouldn't have since she wasn't upset about anything that happened between them and, in fact, wouldn't mind if it happened again.
The next day, Chase tells his co-workers all about the woman's apartment and also that he slept with her again. As House enters, they change the subject back to Driscoll, noting that none of their tests showed anything and his heart rate is getting worse. All of the Cottages get a page, but it's not about Driscoll this time: it's from the ER.
Whoever runs the ER now that Cameron is gone shows them to a recent admit with the same symptoms as Driscoll: Landon. Oh, I guess I was wrong about him being just a red herring after all. I should have known when I realized he was the guy from Everybody Hates Chris that his part would be significant.
