“The Big Bang Theory” Season 10, episode 4 will see Amy (Mayim Bialik) moving into Sheldon’s (Jim Parsons) apartment.

According to the show’s official spoiler site, Amy’s apartment gets flooded, so she asks Sheldon if she could move in with him temporarily. In “The Cohabitation Experimentation,” Sheldon agrees to live together with Amy, but it is expected that their new living arrangement won’t be a peaceful experience for both of them. 

While speaking with Entertainment Weekly, executive producer Steve Molaro said that Sheldon and Amy will attempt to adapt to the changes by supporting each other through the ordeal. “Everyone will have all the apprehensions of whatever they’re gonna feel and they’ll work their way through it like they have for the past six years,” he said. Amy and Sheldon’s problems will continue in episode 5, titled “The Hot Tub Contamination.” The installment will air on CBS on Monday, Oct. 17.

Meanwhile, “The Big Bang Theory” Season 10, episode 4 is about Howard (Simon Helberg) and Bernadette (Melissa Rauch) talking about the sex of their baby. The couple become curious about it, so they contemplate if it’s the right time to know their baby’s sex. By the looks of it, this big revelation will not take place this early on in the season. After all, Molaro told The Hollywood Reporter earlier this year that they still haven’t decided if Howard and Bernadette’s baby is a boy or a girl.

Howard and Bernadette will also also spend some quality time together in Palm Springs in “The Hot Tub Contamination.” However, details about their rendezvous are still being kept under wraps. The trip will also be Bernadette and Howard’s first time being alone together since announcing that they are expecting.

“The Big Bang Theory” Season 10 airs Mondays at 8 p.m. ET on CBS.
