‘The Big Bang Theory’ Season 10 Episode 6 Spoilers & Promo: Stardom For Penny? Wolowitz’s Baby Woes, New Milestone For Shamy

Episode six of "The Big Bang Theory" Season 10 will highlight Penny's (Kaley Cuoco) days of being an actress. Wolowitz (Simon Helberg), meanwhile, will feel the stress of becoming a first-time dad.

The new "The Big Bang Theory" episode titled "The Fetal Kick Catalyst" will feature Leonard (Johnny Galecki) convincing Penny to attend the Van Nuys Comic Con, where she meets people who were fans of her performance in "Serial Ape-ist," Spoiler TV reported. "Serial Ape-ist" is a low-budget horror film that Penny did when she first arrived in Los Angeles.

Amy (Mayim Bialik) and Sheldon (Jim Parsons), on the other hand, will host a brunch at Penny's apartment in episode six of "The Big Bang Theory." Wolowitz will make an impulsive purchase while freaking out over the impending arrival of his and Bernadette's (Melissa Rauch) baby.

Kevin Sussman and Brian Posehn are reprising their respective roles as Stuart and Bert in the upcoming "The Big Bang Theory" episode. Check out photos from episode six on Spoiler TV. Watch the promo below.

Future "The Big Bang Theory" episodes will highlight Sheldon and Amy's temporary cohabitation or five-week experiment in Penny's apartment. It was fun seeing Amy standing up to Sheldon after the first night of their cohabitation -- a feat that Leonard can't really accomplish in the past. This raised questions about whether Amy is the one person who can finally tame Sheldon's frustrating quirks.

In an interview with The Hollywood Reporter, "The Big Bang Theory" showrunner Steve Molaro said that Amy doesn't necessarily want to "tame" Sheldon because those quirks are a huge part of his identity and she loves him for it. Molaro said that Amy would probably "settle for just helping him rein them in from time to time," adding that she is "good at knowing when to pick her battles."

For Molaro, exploring Sheldon and Amy's relationship on "The Big Bang Theory" is great because "so much is new to them." Even something as small and simple as brunch and inviting people over can be an adventure and a milestone for the couple.

Leonard and Penny will have a hand in Sheldon and Amy's new arrangement in "The Big Bang Theory." The couple will help out in their friends' cohabitation experiment and they will "have great motivation, because if it fails they get Sheldon back," Molaro jokingly added.

"The Big Bang Theory" Season 10 returns for its sixth episode on Thursday, Oct. 27 (8:00-8:31 PM, ET/PT) on CBS. What are your thoughts on Sheldon and Amy's new living arrangement? Tell us below.
