House and Dominika rehearse and study to make it look like they have been living together even though they have been separated most of the time they were married. Mr. Weinmann comes to 221B Baker Street to interview them and despite asking tough questions, House and Dominika do well enough to fool him. However, Weinmann tells them he has to speak to their neighbors. Dominika is worried, but House has it covered - he's convinced Wilson to pretend to be a neighbor. Weinmann finds Wilson, and Wilson says he's seen House and Dominika together a lot. However, one of House's real neighbors finds Wilson outside his door and recognizes him as one of House's friends. Weinmann realizes he has been fooled and tells House and Dominika to come to his office the next morning.
