'The Big Bang Theory' season 10 spoilers news: Sheldon's big mouth upsets Amy as Koothrappali goes broke

It seems that Sheldon (Jim Parsons) is in dire need of a little relationship ethics, and the next episode of the CBS sitcom "The Big Bang Theory" may give him just that. Although the occasional fights may actually be helpful in strengthening relationships, will Sheldon survive the one he's about to have with his girlfriend, Amy (Mayim Bialik)?

In the episode titled "The Allowance Evaporation," a fight breaks out between couple Sheldon and Amy, which will count as their first one since moving in together. What could have happened to bring this on? Will both or either one of them cool down soon enough to try and fix things before their relationship completely crumbles?

The trailer for the next episode may have just revealed the reason behind the couple's altercation: Sheldon's big mouth. It turns out that Sheldon has been sharing intimate details about their relationship to his peers, which, in turn, has spread said details to everyone else at the university.

"Other than you two only having sex once a year, you're the perfect couple," a mutual peer tells Sheldon and Amy in the trailer. It may have been an innocent remark meant as a compliment, but it still hits Amy in all the wrong ways.

Since Amy has previously expressed her disappointment over a lack of marriage proposal from his boyfriend, what Sheldon does to remedy this little bump in their relationship could be crucial to keeping Amy by his side. Will the engagement ring storyline from before finally be explored or hinted at again in the upcoming episode?

Meanwhile, the true meaning of the episode title concerns Koothrappali (Kunal Nayyar), who will stop receiving financial support from his father and will thus be forced to face the shocking realities of financial independence.

"The Big Bang Theory" season 10 episode 16 airs on Thursday, Feb. 16, at 8 p.m. on CBS.
