The upcoming season of "The Big Bang Theory" will bring some big changes, including Stephen Hawking's return, a possible "Shamy" engagement, and another baby along the way! Check out some of the things you can expect from "The Big Bang Theory" Season 11 Episode 1.

"The Big Bang Theory" Season 11 will pick up after Sheldon went on a long flight from his apartment to see Amy in New Jersey. In the last episode, Sheldon (Jim Parsons) asked for Amy's (Mayim Bialik) hand in marriage.

The promo opens with the main characters asking about speaking Klingon, eating Kale, and other random things, but Leonard (Johnny Galecki) was the only one who sounds sane among all of them.

Amy's final answer

The promo also showed the partial aftermath of Sheldon's proposal, but they were interrupted by Leonard's call. Because Sheldon is a rule-abiding guy, he decided to end that precious moment and answer his BFF's call.

Sheldon revealed Ramona (Riki Lindhome) kissed him. According to him, it was a funny story but Leonard, Amy, and Penny (Kaley Cuoco) were shocked upon hearing it. However, Ramona's kiss made Sheldon realize that Amy is the only woman for him.

The show's head Steve Holland, who assumed the role after Steve Molaro left for the "Young Sheldon," told Variety that it might bring up some issues between Sheldon and Amy, especially since Ramona will also appear in Season 11.

As far as Amy is concerned, Holland and the team worked on the plot which they think is the most "real and natural" reaction they can get from Bialik's character. We can only hope that "Shamy" will push through the engagement despite the kiss

Stephen Hawking returns to 'The Big Bang Theory'

Holland also said another appearance of a huge character besides Lindhome.

The new showrunner teased that "The Proposal Proposal" episode will include a cut scene from the Season 10 finale. According to him, Sheldon will ask someone "genius" for his approval before proposing to Amy.

Steve Holland revealed to TV Guide, "So we do a little bit of a flashback and see that when he left the kiss and Caltech but before he gets to Princeton to propose, he did make a stop to talk to somebody.

"

"The Big Bang Theory" has not delved on the identity of this character but recent spoilers might have some clues. According to the outlet, Stephen Hawking will appear for the third time. This is after he portrayed himself in episodes which aired in 2012 and 2016.

Hawking and Sheldon did have a huge connection as seen in the previous episodes. Leonard and the others are big fans of the famed theoretical physicist but it was Sheldon who "worships" him since childhood. Is Stephen Hawking the mysterious guest star in the Season 11 premiere episode?

Baby No. 2 and a possible romance?

Howard (Simon Helberg) and Bernadette (Melissa Rauch) might be expanding their family soon. The synopsis says that the two will have another offspring aside from Halley.

In real life, Rauch and husband Winston Beigel are expecting their first child this year.

The promotional photos, on the other hand, featured other characters as well. Raj (Kunal Nayyar) will yet again see Ramona (Lindhome). We can assume that he is likely to hit on her again because Ramona really liked Sheldon. Since his friend has proposed, things might go well between Raj and Ramona now.

Are you excited for "The Big Bang Theory" Season 11? Episode 1, called "The Proposal Proposal," will air on Monday, Sept. 24, 2017, at 8 p.m. on CBS. Stay tuned for more updates.
