"The Big Bang Theory" Season 10 adds Katy Sagal as Penny's (Kaley Cuoco) mom and brother (Jack McBrayer). The Kaley Cuoco family reveals with Katy Sagal and Jack McBrayer join new changes made to "The Big Bang Theory" series. These "TBBT" changes include normalizing Sheldon Cooper (Jim Parsons) and Amy Farrah Fowler (Mayim Bialik) as a couple, and pregnancy for Bernadette (Melissa Rauch) and Howard Wolowitz (Simon Helberg).
Although doubts cropped up for "The Big Bang Theory" Season 10 given "TBBT" S9 twists, as reported on Parent Herald, S10 seems steadily shaping up. Digital Spy highlights that Kaley Cuoco seeing a reveal of Penny's mum in "The Big Bang Theory" Season 10 is a big deal.
"The Big Bang Theory" series has never given a clear picture of what family background Kaley Cuoco was channeling for Penny. The media outlet points out that aside from short appearance by Keith Carradine as Penny's dad, Kaley Cuoco has never had to work with family history on "The Big Bang Theory" series.
Interestingly, this changes in a big way for Kaley Cuoco in "The Big Bang Theory" Season 10 as Digital Spy reports. Not only does Penny get a family in "TBBT" S10, but Kaley Cuoco will also see her character dealing with all the issues that come with family when Katy Sagal (as Susan) and Jack McBrayer (as Penny's brother Randall) crash "The Big Bang Theory" Season 10.
Mainly Kaley Cuoco will be dealing with drug issues in "The Big Bang Theory" Season 10. This is because Jack Mcbrayer plays a drug dealer, who's pushing mom Susan over the edge who turns to Penny in desperation.
Meanwhile, everyone is getting paired up in "The Big Bang Theory" series - even Leonard Hofstadter's (Johnny Galecki) dad Alfred (Judd Hirsch) and Sheldon Cooper's (Jim Parsons) mom Mary (Laurie Metcalf). Is Raj Raj Koothrappali (Kunal Nayyar) then up for a big romance in "The Big Bang Theory" Season 10?
