Other mistake: When Lucas and Zoe are at the restaurant, Zoe steals the staff list from the kitchens. It is an established fact that a waitress named Stephanie works in the restaurant, however when the camera closes on the list, her name is not listed among the other staff members.
Francis Underwood: Such a waste of talent. He chose money over power. In this town, a mistake nearly everyone makes. Money is the Mc-mansion in Sarasota that starts falling apart after 10 years. Power is the old stone building that stands for centuries. I cannot respect someone who doesn't see the difference.
