Katey Sagal is set to play Penny’s mother, Susan. She will appear in the first episode of Season 10 when the show comes back this fall. It is unknown if she will appear in a single episode or multiple episodes. This isn’t the first time Sagal has been seen onscreen with Kaley Cuoco. She also played Cuoco’s mother in 8 Simple Rules for Dating My Teenage Daughter. 

Jack McBrayer will play Penny’s brother. What little we know about his character from previous seasons of the show is that he is a drug dealer and has been to prison for his drug dealing ways. He will also appear in the first episode of Season 10, and it is unclear if the episode will be his only appearance.

The Big Bang Theory left off last season with Leonard and Penny set to renew their wedding vows. Season 10 premiere will air on September 19th on CBS!
