External office. Chase says the problem is probably neurological. House is more interested in getting quizzed on his wife's brothers' names. Adams thinks it's weird that House memorizes every detail of their lives, but can't seem to grasp his wife's details. Park suggests multiple sclerosis brought on by the testicular damage. House says she's on the path to being team leader, but she's the only applicant. Suddenly, Chase and Taub both want to be it.

Chase, Adams, Taub and Park walk through the halls talking about the position. They all want it now. Taub thinks they should stop fighting, but I notice he's not pulling his name out of contention.

Taub tells Joe they'll be looking for proteins in his spinal fluid and also running an MRI. Joe says he's feeling weird about the testosterone. What if his big spiritual change was just chemistry? Adams says to think of the assault as a catalyst, which seems like even more chemistry to me.

Chase wants Foreman to tell House to drop the team leader idea. But Foreman thinks it's a good idea. Now Chase just wants it to not be Adams. Or Park. Or Taub. Foreman points out that Chase is angling for a job that he mocked back when it was Foreman's. He is not interested in his problems.

House and Dominika rearrange his apartment and put pictures of famous Ukrainians on the wall. She dances about. It is weird. Park arrives and objects to the Amy Grant. She's here to make them study. She brought a protractor on the grounds that, "You never know when you might need to make a pie chart." She is going to be a harsh taskmaster. But she brought Red Bull! I'm going to be perfectly honest here: I would be totally into the idea of a woman coming around to my house to make me study. No, you shut up!

Taub and Adams talk about testosterone's effects on behavior. They also occasionally glance at the tests they're supposed to be running on Joe. His brain stem and spinal cord are clean. He doesn't have MS. But when he goes to scratch his nose, he reports that he's seeing double.
