The Big Bang Theory returns Thursday with an all-new episode ironically titled Spoiler Alert Segmentation

While most of the scoops on the respective installment have already been released, new spoilers surfaced in regards to next week's The Tangible Affection Proof episode on Valentine's Day.

The half-hour lover's day extravaganza will feature a whole lot of love in the air for the beauties and geeks. However, complications will arise when Kaley Cuoco's real-life sibling, Briana Cuoco, shows up on the program.

The romantic foursome - which consists of Leonard, Penny, Howard and Bernadette - will go out together for a double date. Although Leonard and Howard have plans of treating their significant others to a nice dinner, the situation doesn't pan out as planned.

While dining, Penny sees her ex-boyfriend Matt and the girl that he was unfaithful to her with, Gretchen - played by Cuoco's sister.

As Penny and the group deal with the less than ideal encounter, Raj and Stuart are plotting a singles-only party at the comic book shop in order to meet some ladies of their own. Sheldon and Amy will be searching for girls themselves.

Mayim Bialik, who plays Amy, recently spoke to E! News and explained that her character's forceful attitude could create quite a stir.

"Amy is really pushing the envelope with Sheldon. It's been really interesting and really multidimensional how he reacts and what he does with that information," she said. 

The moment of culmination in the Sheldon/Amy relationship will more than likely occur in the Valentine's Day episode, which is reportedly being set up to really change the direction of each character's relationship dynamic.

The Big Bang Theory will be airing on Thursday, Feb. 7 at 8 p.m. EST on the CBS network.
