Brandon and Brenda are sitting in the room with the other set of twins when Harriet Strathmore gives them a series of tests to determine their closeness and the other set of twins make Brandon and Brenda feel uncomfortable with their closeness. Glen asks Cindy about what if she hadn't met Jim. Cindy needs to leave for home, but he will only let her leave if she agrees to go to his art opening tomorrow.
