"The Big Bang Theory" season 10 episode 16 shows a big fight between Amy and Sheldon. Also, Raj runs out of his allowance and he needs to prove to his parents that he is mature enough to handle that.

In the last episode of "The Big Bang Theory", Sheldon Cooper shows his love about trains and locomotive engines. Now fans will see his another side, as he fights with Amy.

Amy was willing to drive him out for hours to see a train exhibition in Nevada because Sheldon likes it. Well, it is obvious that Sheldon should also show some consideration. But as written in CarterMatt, being considerate is not something which Sheldon do and he could pose some pretty serious problems for him and Amy in next episode of "The Big Bang Theory".

Episode 16 is named "The Allowance Evaporation" and there is a reason behind that. Rajesh Koothrappali stops receiving support from his father and after that, he feels shocked by watching his financial independence. As shown in "The Big Bang Theory", his father is wealthy and supports him when he needs financial help.

Sheldon is the one to kiss and tell and it is the reason behind the dispute between Amy and Sheldon. Sheldon tells everyone about their sex life and Amy is furious about it. Sheldon is kind of that character in "The Big Bang Theory" who does not know what to speak and what not to speak in public.

Sheldon wants to share what he feels and his experience while Amy likes to keep some things private. There are many dissimilarities between these two, but this is bigger than everything. According to Yahoo News, "The Big Bang Theory" season 10 episode 16 will feature Amy and Sheldon's first major fight as girlfriend and boyfriend.

The promo shows that Amy and Sheldon are having dinner with Bert. While taking dinner, Bert speaks out that Amy and Sheldon only have sex once a year and Amy is shocked to hear that. She asks Bert how he knows about it and he tells that everyone at the university knows about that. When Amy asks Sheldon angrily, he replies that he only told Leonard, Howard, Raj and the lunch lady at the cafeteria and he wonders how everyone else knows about this. "The Big Bang Theory" season 10 episode 16 will air on February 16 at 8 pm EST on CBC.
