On the episode “The Collaboration Fluctuation” – Leonard, Penny and Raj adjust to their new living arrangement, and Sheldon takes an interest in Amy’s work, on a rebroadcast of THE BIG BANG THEORY, Monday, Sept. 18 (8:00-8:30 PM, ET/PT) on the CBS Television Network. (Originally broadcast 3/30/17.)
Leonard and Sheldon are brilliant physicists – geniuses in the laboratory but socially challenged everywhere else. Enter beautiful, street-smart neighbor Penny, who aims to teach them a thing or two about life. Despite their on-again, off-again relationship in the past, Leonard and Penny have finally gotten married.
Even Sheldon has found a female companion, entering into a “relationship agreement” with neurobiologist Amy Farrah Fowler, and he recently took their relationship to the next level by proposing marriage. In their free time, Leonard and Sheldon enjoy fantasy role-playing games with their ever-expanding universe of friends, including fellow scientists Koothrappali, Wolowitz and Wolowitz’s adorable microbiologist wife, Bernadette, who is adjusting to life with their new baby girl.
