History TheBigBangTheory / SeasonEleven

* {{Revival}}: InUniverse. A new version of ''Professor Proton'' is being planned, and Sheldon is not too happy about it. Especially when [[spoiler:Creator/WilWheaton is cast as Proton.]]

* WriteWhoYouKnow: Invoked in "The Novelization Correlation". Leonard's mystery book has a character named Inga, who is blonde, beautiful, and mean to the main character. Bernadette assumes the character is based on Penny, while Penny thinks it's actually Bernadette. Leonard then realizes that he had unconsciously based her on [[spoiler:his mother, and he decides to stop writing.]] The scenes reenacting scenes from the book also feature Howard and Raj as two scientists and Stuart as a bumbling janitor.

* WorthlessYellowRocks: In TheStinger for "The Bitcoin Entanglement" [[spoiler: it's revealed that the Batman flash drive containing the now very valuable bitcoins was accidentally left in Stuart's comic book shop, he wiped the drive and resold it for ten dollars]].

* ItsAllAboutMe: When Sheldon and Amy are figuring out wedding details, they become concerned about choosing the right people for the best man/maid of honor positions, in part because they don't want to hurt any feelings for not being chosen. After a long episode where they run tests on their friends to see who would be best suited for the jobs, Leonard tells him that since it is his wedding day he is ALLOWED to be selfish and everyone will understand. "You have kind have been training for this your entire life."

* EurekaMoment: Sheldon reached a new discovery about the nature of String Theory by explaining it to Penny. She has functionally no clue what he is actually talking about, but the process of simplifying the problem and her asking basic questions made him look at it in a different perspective.

Sheldon and Amy finally get engaged. Howard and Bernadette are expecting again. Raj cuts Howard from his life after finding that his constant ridicule has affected his confidence.

* OddFriendship: Raj slept with a girl and found out that she was technically still married, she had separated from her husband just a few weeks prior. He ended up meeting the husband when he came looking for him, despite seemingly like there was there to attack Raj he instead broke down in tears over what happened to his marriage. They ended up becoming friends and Raj ended up creeping out the girl enough that she went back to her husband. And they STILL hang out.

* StatusQuoIsGod: Discussed by Leonard and Penny when trying to write a Christmas letter about their lives, as they both had a tough time with work (Leonard released from the air force project and Penny hates her job) and they were in their second anniversary but [[ForgottenAnniversary both forgot to celebrate it]], leading to their highlights as being "Still Employed" and "Still Married." They end up discussing where they go from here, even bringing up buying a house and having kids, but end up agreeing that life is good right now and they don't have to rush into any big changes.

* OOCIsSeriousBusiness: When Raj gets upset noticing how mean spirited Howard can be as a friend, Penny realizes she unfairly teases Leonard in a similar way and tries to be more positive around him. Leonard was not prepared for that, feeling like it is another form of SarcasmMode.

* TheFoodPoisoningIncident: In "The Celebration Reverberation", Sheldon makes an authentic pioneer meal for Amy's birthday, based on her love of ''Literature/LittleHouseOnThePrairie.'' They spend much of the rest of the episode throwing up.

* CharacterDevelopment: After years of WillTheyOrWontThey, CommitmentIssues, {{Romantic False Lead}}s, TrueLoveIsExceptional, TrueLoveIsBoring and PoorCommunicationKills, Leonard and Penny have reached a place where they are more in tune with what each other is feeling and what they want. The previous season they had a big fight where Penny expected Leonard to surprise her with a romantic evening, the season premiere Leonard got her a cake worried that she was feeling ignored after all the attention given to Sheldon and Amy getting engaged and Bernadette being pregnant. Later on, Leonard was struggling with writing a Christmas card and how mediocre their year has been (Leonard was removed from the air force project and Penny is making good money but hates her job, meaning all they can really say is "still employed"), and Penny consoles him that they don't need to do anything big but just enjoy their time together.

* TheFoodPoisoningIncident: In "The Celebration Reverberation", Sheldon makes an authentic pioneer meal for Amy's birthday, based on her love of ''Literature/LittleHouseOnThePrairie''. They spend much of the rest of the episode throwing up.

* RelationshipRevolvingDoor: It's mentioned that the other characters have nicknames for the different times Leonard and Penny broke up. Which is kind of interesting, as officially they got together in the beginning of the third season, only one actual break up later in the season and they get back together tentatively in the fifth season (becoming more affirmative in the sixth) so they were never really depicted as constantly on-again, off-again. So it is something of a RetCon, but multiple episodes do depict them as ending with a big argument with no real resolution (such as the season seven "Hesitation Rammification" where a drunk Penny proposes to Leonard), and that might be what the other characters are referring to.

* FencePainting: In "The Collaboration Contamination," Sheldon is jealous that Amy is collaborating with Howard on a project, and Bernadette uses this to get him to do chores around the house, telling him that Howard loves doing chores and Sheldon doing them for him would upset him. She even mentions the TropeNamer when she asks Sheldon if he's read ''Literature/TomSawyer.''

Sheldon and Amy finally get engaged. Howard and Bernadette are expecting again.

* BaitAndSwitch: In "The Proposal Proposal", Amy walks over to Ramona, but instead of confronting her for [[spoiler:kissing Sheldon]], she thanks her because it caused him to propose.

* ForgottenAnniversary: Played with as both Leonard and Penny forgot their anniversary. Leonard made a cake for Penny, worried she was feeling left out after the attention given to Bernadette's pregnancy and Sheldon and Amy getting engaged. Penny thought it was for their anniversary, and after Leonard checked his phone to confirmed it WAS their anniversary Penny already had a mouthful of cake while exclaiming "Happy anniversary!"
