The Big Bang Theory returns next Monday and there’s lots of surprises in store.
In the season 10 premiere, Leonard (Johnny Galecki) and Penny (Kaley Cuoco) plan to renew their vows, but not without some drama. We meet Leonard’s dad (Judd Hirsch), who may have slept with Sheldon’s (Jim Parsons) mom (Laurie Metcalf), and Penny’s mother (Katey Sagal) and drug addict brother (Jack McBrayer) make their own debut.
“Penny’s close with her dad [Keith Carradine],” Executive Producer Steve Molaro says of the episode. “As we know, her brother Randall has been a bit of trouble over the years, selling drugs and being in and out of jail, and that’s put a lot of stress on her mom. You will pick up on the tensions between her mother and her brother very quickly, and you get a glimpse of Penny and her dad being caught in the middle of that.”
Check out a few photos from the episode.
The Big Bang Theory returns Monday, Sept. 19 at 8 p.m. ET on CBS.
