Last week’s THE BIG BANG THEORY was all about the gathering of family for the re-enacting of Leonard and Penny’s wedding. We met Penny’s mother and brother for the first time, and we picked up where last season left off in the supposed encounter between Leonard’s father and Sheldon’s mother — there was no “there” there, although there was a hint that there may be a “there” there some day in the future. And as Amy drove Sheldon’s mother to the airport after the wedding, Sheldon’s mother taught Amy how to put Sheldon in his place. All good fun.
In this week’s episode, we’re treated to two important story lines. We knew from last season that the military was interested the guys’ award-winning paper and the resulting patent on the infinite persistence gyroscope. Last week a representative from the Air Force Department of Material Command showed up to talk with Howard, and Howard, who has been nervous about government “spooks” following him everywhere, avoided contact. This week, he finally gets the visit. Also last season we learned that Howard and Bernadette were expecting a baby, and this week we find out that Bernadette has been keeping the news a secret at work. Only, a certain friend let the news slip out to a colleague and now Bernadette is worried about the impact that might have.
