'The Big Bang Theory' season 10 episode 6 spoilers: Bernadette and Howard feel their first baby kick; Penny attends comic convention

Penny (Kaley Cuoco) joins a comic convention, and the Wolowitzes get their first baby kick in the upcoming episode of CBS' top-rating comedy series "The Big Bang Theory" season 10.
Titled "The Fetal Kick Catalyst," the next episode marks the show's move to Thursday night. According to spoiler reports, the characters are about to experience a bunch of firsts. Penny goes to a comic convention for the first time as a guest, while Sheldon (Jim Parsons) and Amy (Mayim Bialik) engage in a brunch session and invite their friends over. Meanwhile, excited new parents Howard (Simon Helberg) and Bernadette (Melissa Rauch) finally feel their first baby kick.
Sheldon and Amy are currently in their temporary five-week "experiment" of living together as a couple, while Amy's apartment is being fixed after it got flooded. Speaking with The Hollywood Reporter, showrunner Steve Molaro shared his thoughts on the possibility of the pair's cohabitation experiment having a longer tail.
"We are open to anything. That's what's fun about the experiment," he said. "They could stay together, they could try going back to the way it was, they could end up anywhere. It's exciting." Molaro added that Sheldon and Amy's new living arrangement "also functions as a creative experiment" that lets the creators and writers explore more angles in the characters' unique relationship.
In the recently-released promo from CBS, the show announced its move to Thursday night airing. For the uninitiated, the switching of time slots happens every year due to the Thursday night football schedule. Once the game is over, CBS moves "The Big Bang Theory" into that Thursday night time slot. "The Fetal Kick Catalyst" is slated to be the first episode to air in the said time slot starting on Oct. 27.
Catch all-new episodes of "The Big Bang Theory" season 10 airing every Thursday night at 8 p.m. ET on CBS.
