The king of sitcoms teamed up with Bill Prady and Steven Molaro as both producers and head writers to create the Big Bang Theory series, it definitely came as no surprise that the series has been a big bang.

Episode 1 of The Big Bang Theory Season 12 began with Sheldon and Amy’s honeymoon in New York. Sheldon displays queer desire to schedule their sex life much to Amy’s chagrin. Raj instigates a feud on Twitter with renowned American astrophysicist, as Mr. Fowler, Amy’s dad, is seen hiding from his wife but is scared into returning home by Penny.

The newlyweds had a hard time figuring out their wedding gift from Leonard and his wife which turned out to be a gift from Raj to Howard and then from Howard to Leonard. Raj, on the other hand, is desperate for a relationship and turns to his father for help in finding a wife. His father chooses Anu whose domineering attitude leads to her proposing marriage to Raj. Yes, he accepted and upped it by giving Leonard and Penny, a relationship questionnaire to complete. This reveals that Penny doesn’t desire a child while Leonard does but comes to accept her wish. Meanwhile, Stuart ‘stupidly’ began to bring Denise home at night.

Sheldon made up with Tam, his Texan childhood friend who abandoned him for a girlfriend as Penny and Bernadette try to form a friendship with Anu, embarrassing Raj in the process. Like all newlyweds, Sheldon and Amy have challenges with balancing their career and time together; Sheldon hurts his wife but apologizes. Also, after much skepticism, Raj allows Leonard to join him on his show and they do just fine.

Halloween comes with lots of drama and hurtful actions for the group and just after that, Bernadette starts going to Haley for some alone time and is soon joined by Penny. Anu finally has sex with Raj after a failed attempt while Sheldon bonds with his mother-in-law as a means of spiting his father-in-law who prefers Howard and his magic to him.

Furthermore, Leonard’s finding of a paper which disproves Sheldon and Amy’s work on super asymmetry leads them into depression until an old VHS tape gives them hope again. Subsequent episodes of The Big Bang Theory Season 12 promises more interesting drama even as the sitcom winds to an end.

Somehow, she fell in love with Leonard following so much drama and the duo got married in season 9. She is a major part of the story and it’s only natural for her to be a member of The Big Bang Theory Season 12 cast.

Unlike his friends and wife, he doesn’t have a Ph.D. and isn’t a Physicist.
