"The Big Bang Theory" Season 8 is on two weeks Thanksgiving break. There is no episode on Nov. 27, 2014. The popular CBS' comedy series is scheduled to return on Dec. 11, 2014, with episode 11. The title of the new episode is "The Clean Room Infiltration." The synopsis of the episode reveals that Amy will be busy preparing Christmas Eve dinner for her boyfriend and friends.

According to the official synopsis of "The Clean Room Infiltration," "Amy will fix a traditional Victorian Era Christmas Eve dinner whose guest list is going to include Raj's newly separated father, visiting from India." It is in episode 9, "The Septum Deviation," that Raj found out that his parents are separating.

The last episode saw Sheldon and Amy co-hosting the final episode of Sheldon's Web series "Fun with Flags." However, at the end of the episode, Sheldon decided to revive his show after receiving a comment that it was sad to see the series end. Also in the episode, Leonard, Raj and Howard reflected on their career while cleaning the office of a professor who did not accomplish anything. And, Penny tried to make Bernadette realise that her behaviour made her colleagues upset.

The spoilers reveal that Sheldon and Amy are going to kiss again in the upcoming Christmas special episode. In the last season, Sheldon kissed Amy on her lips and he liked it. And, in one of the previous episodes of the current season, Sheldon confessed to Amy that he loves her.

In "The Clean Room Infiltration," Amy's kiss is not going to make Sheldon happy. According to the spoiler, Sheldon will be in a mood to punish Amy. His idea of punishing his girlfriend is by buying her a present. According to the spoiler, he will give Amy a photo of himself with the Santa. She is going to like the present. Amy also has a present for Sheldon -- his favourite cookies from his maternal grandmother's (Meemaw) recipe.

Also in the episode, Leonard and Howard will be performing an experiment on Christmas Eve. A bird will put a break on their work. Raj will join them and the three will be seen arguing about who is smarter, according to the spoiler.
