Following the gang’s downright emotional hijinx in Season 9, episode 19, “The Big Bang Theory” returns Thursday with an all-new episode. As each member of the group navigates the ever changing world of adulthood and relationships, they find themselves, once again, testing if their collective friendship can withstand the dramatic onslaught. 

According to an official plot synopsis from CBS, episode 20, titled “The Big Bear Precipitation,” will see a double date of sorts. The show’s most prominent pairs will decide to embrace adult life and take a dual couple’s weekend away together. While on a cabin trip with their girlfriends Penny (Kaley Cuoco) and Amy (Mayim Bialik), Sheldon (Jim Parsons) accidentally reveals a secret that Leonard (Johnny Galecki) previously entrusted him with. 

Meanwhile, when Raj (Kunal Nayyar) starts to go overboard getting baby gifts for the expecting couple of Howard (Simon Helberg) and Bernadette (Melissa Rauch), they’re forced to take a stand and put a stop to the cavalcade of free stuff. It seems fans are in store for a pretty awkward conversation between both the members at the cabin and the group that stayed behind, apparently with a very large bear.

Secrets have been a bit of a trend on “The Big Bang Theory” this year. Just last week Sheldon took a major step forward with Amy by revealing his storage unit containing all the things he’s deemed “too sentimental” to throw away, such as every toothbrush he’s ever used. As previously reported, the secrets and adult lifestyle began when Sheldon revealed he was going to propose to Amy just before she temporarily broke up with him. Now, with the couple back together, Sheldon sharing his biggest secret and the duo having finally been physical with one another, there’s no telling what demons from the past could make their way to the forefront and shake up the group’s dynamic.

After all, things will change on the show moving forward thanks to the upcoming birth of Howard and Bernadette’s child. However, as TV Line previously noted, the baby will exist without actually causing dramatic change to the everyday dynamic of the cast. 

Fans curious to see how it all shakes out in the final episodes of “The Big Bang Theory” Season 9 can tune in to “The Big Bear Precipitation” on Thursday at 8 p.m. EDT on CBS.
