‘Big Bang Theory’
Amy (Mayim Bialik) finally gave Sheldon (Jim Parsons) a resounding yes in “Big Bang Theory” Season 11, episode 1. CBS

“Big Bang Theory” Season 11 just premiered on Monday and already there is another big problem concerning Amy (Mayim Bialik) and Sheldon (Jim Parsons).

In “The Proposal,” the major cliffhanger from Season 10 was addressed. Amy says “yes” to Sheldon’s question, and the two begin preparing for their big day. But during an interview with TV Line, “Big Bang Theory” showrunner Steve Holland hinted on the possibility of Amy and Sheldon’s wedding not happening this season.

“Sheldon and Amy planning their wedding will certainly be an arc throughout the season. I can’t promise that we’ll see a wedding at the end of the season, but we’ll certainly be building towards a wedding,” he explained.

Holland added that they are also interested in writing a bachelor and bachelorette party storyline for the couple. “We’ve written about eight episodes so far this season, and… Sheldon is actually trying to make this wedding perfect but in his own Sheldon way: being super-controlling and having opinions about everything. It’s been fun watching the two of them compromise,” he said.

Meanwhile, there’s another shocker in “Big Bang Theory” Season 11, episode 1. Bernadette (Melissa Rauch) and Howard (Simon Helberg) are expecting another baby. In the installment, Hallie’s parents appeared to be thrown off by the news. “I think we tried to play that moment very real. This was not something they were planning, so it’s a bit of a punch. It’s going to take some time for them to come to terms with this,” Holland said.

Last season, the couple also struggled with Bernadette’s pregnancy. Howard was worried that he won’t be a good dad to Hallie since he didn’t grow up with a father figure. But a second pregnancy doesn’t mean that they are more prepared to raise a child.

But in the end, the people behind “Big Bang Theory” wanted to write Rauch’s real-life pregnancy into the series because it could bring exciting storylines into the mix. “We thought a surprise second baby could be a really interesting curveball to throw at Howard and Bernadette,” he said.

“Big Bang Theory” Season 11 airs Mondays at 8 p.m. EDT on CBS.
