The psychologist hired to observe Mary, Dr. Shelley Finkle, is played by Ali Marsh, Frederick Weller's real life wife.
This episode features a fast food establishment called "Bob's Burgers". The dialogue implies that it's a national (or at least regional) chain, when one person says, "I didn't know New Mexico had Bob's Burgers." In reality, there really is a chain of fast food restaurants called "Bob's Burgers" and in fact, that shot was filmed at one of their locations (with the corporate logos and menu boards changed), however, its a purely local chain of restaurants, with all of their locations in Albuquerque, or the surrounding area. So, any other restaurant named "Bob's Burgers" outside of New Mexico is not the same chain as portrayed in the episode.
