Sheldon (Jim Parsons) will preside over his girlfriend's brunch party in the upcoming episode of "The Big Bang Theory."

In the episode titled "The Fetal Kick Catalyst," the synopsis (as per CarterMatt) reveals that Amy (Mayim Bialik) will be hosting a small party at Leonard (Johnny Galecki) and Penny's (Kaley Cuoco) apartment. Sheldon's participation is a must, considering how they fought last episode. Amy was disappointed that her boyfriend kept on insisting he was uncomfortable with their living arrangements. She suggested living together when her apartment had to be fixed. Sheldon was okay at first, but when she started changing his usual schedule in the bathroom, he complained.

In the end, Sheldon said sorry to Amy, especially after he had suggested they find other people to date. As per the promo, he will try everything to welcome the guests. Sheldon will even attempt to open a bottle of wine. As expected, he will have a hard time doing so, but the visitors are entertained by his comical actions. Meanwhile, Penny will learn that she has fans while attending the Van Nuys Comic Con with her husband. Will this push her to return to acting? She has always claimed being an actress was her dream.

Elsewhere, Howard (Simon Helberg) and Bernadette (Melissa Rauch) are getting excited to see their baby. As per the synopsis, he will buy something spontaneously after thinking that they are not yet prepared for the baby's arrival. Last episode, the couple was supposed to go on a vacation. Bernadette's morning sickness, however, prevented them from doing so. It was a peaceful day at home until Stuart (Kevin Sussman) and Raj (Kunal Nayyar) barged in. Stuart even took some time off to use the Wolowitz family's brand new hot tub.

"The Big Bang Theory" season 10 episode 6 airs on a new timeslot, Thursday, Oct. 27 at 8 p.m. EST on CBS.
