Elsewhere in the episode, viewers will find Amy and Penny going to a party for scientists, but when they reach there the girls realise they are the only ones left as they arrived an hour late. The party is hosted by Amy's colleague Bert, and Penny discovers that Amy is actually one of the popular girls at the work place. However, her own husband, Leonard, is just known for convincing a hot girl to marry him.

Another storyline that will be touched upon is that of Bernadette's pregnancy. Because Howard is busy with the project for the military, Raj will decide to keep Bernadette occupied and he tries to convince her to allow him to be in the labour room when she gives birth. Although Bernadette gets mad at Raj for his interfering ways, she later forgives him when Raj asks his father to talk to Bernadette and help her with her pregnancy mood swings.

The synopsis for The Dependence Transcendence reads: "Sheldon has problems working late hours on their Air Force prototype, Amy and Penny go to a party at work and Raj spends the day with a pregnant Bernadette."

The Big Bang Theory airs Mondays on CBS.
