With the Cottages off doing things, House suddenly remembers that Wilson exists and goes to visit him. He finds him wrapping up with some old lady patient, who tells him to "give Sara a kiss for me." I don't know if that's spelled "Sara" or "Sarah" so I'm going with "Sara" because it's a better way to spell it and it saves time with the fewer letters. Of course, House demands to know who this "Sara" is, but Wilson claims he has no idea, figuring the patient is in the early stages of dementia. House accepts this and tells Wilson to pick which bar they're going to tonight to celebrate the end of Wilson's traditional three month post-break-up mourning period. Wilson says he can't make it tonight because he's "busy." He scampers off before House can pump him for details, so House has to ask Cuddy instead. He thinks this has something to do with the mysterious Sara. Cuddy says she has no idea who Sara is.
Taub and Foreman search Nadia's apartment. She has some strange artwork -- a bunch of framed puzzles. I didn't think anyone actually framed their puzzles. Especially someone with a perfect memory who can just take apart and re-assemble the puzzle any time she wants. Foreman tries to quiz Taub to prepare him for the exam, but Taub says he doesn't want to be challenged -- he actually picked Foreman to be his tutor because he figured he wouldn't want to get involved in someone else's problem. Um, you mean like how Foreman didn't get involved with Taub's problems last week and didn't call his almost-ex-wife to tell her that Taub was trying to save a kid's life? While Taub casually brings up the possibility of buying a copy of the exam, Foreman finds an empty bottle of laxatives in Nadia's garbage.
