"The Big Bang Theory" season 10, episode 16 promo was recently released and it seems to show that Amy is really mad at Sheldon. This is reportedly going to be the first major fight between the couple.

According to Yahoo, the promo showed that Amy (Mayim Bialik) and Sheldon (Jim Parsons) were having dinner with Bert (Brian Posehn). As they continue eating, Bert exclaimed about why the two were only having sex once a year.

Of course, this was considered as a personal detail of their relationship. That is why Amy was surprised that Bert knows about it. And later on, she found out that all of the people in the university they were attending is aware of it.

Meanwhile, Amy asked how Bert knew and he answered that Sheldon himself said it. In fact, not only he revealed this to Bert but to several people as well. This includes Leonard (Johnny Galecki), Howard (Simon Helberg), and Raj (Kunal Nayyar). The worst part is that he even told the lunch lady at the cafeteria about it.

What is there to expect in this episode? The couple will be having a serious discussion about this matter. One scene showed that Amy and Sheldon had the chance to talk inside their bedroom. The latter's girlfriend is furious by the fact that their privacy has not been secured.

TV Guide released the official synopsis for episode 16 titled The Allowance Evaporation. It stated: "Amy is incensed when she discovers Sheldon has shared intimate relationship information with people at the university, and Raj is knocked for a loop when his father stops sending financial support."

Raj will have a financial struggle in episode 16. It has been reported that Raj's (Kunal Nayyar) parents will stop giving him the allowance. This is to teach him a lesson of being independent.
