The Season 10 premiere of "The Big Bang Theory" will see the return of recurring characters as well as the introduction of new ones. Latest set photos from the premiere showcased Leonard and Penny's family coming together as witnesses of the couple's renewal of their wedding vows.
The respective families of Leonard (Johnny Galecki) and Penny (Kaley Cuoco) will bring their drama to the wedding. One of the cliffhangers left behind by Season 9 of "The Big Bang Theory" is Leonard's dad (Judd Hirsch) may have had sex with Sheldon's (Jim Parsons) mom (Laurie Metcalf), Entertainment Weekly reported.
Penny's family, on the other hand, will be at odds as her mother (Katey Sagal) and her drug addict brother (Jack McBrayer) get introduced to the long-running comedy series. Penny's mom and brother have tension between them due to the latter's involvement with drugs and trips in-and-out of jail.
Penny and her dad (Keith Carradine), who she's extremely close with, are always caught in the middle of this crossfire, "The Big Bang Theory" executive producer Steve Molaro told EW. Check out new set photos from the "The Big Bang Theory's" tenth season on TVLine.
Molaro shared that every guest star will have something "great to do" in the premiere episode of Season 10, TVLine reported. He added that all of the characters' screen time "got nicely distributed," though they are hoping that McBrayer and Sagal will appear again in an episode that's less crowded.
Another new face on "The Big Bang Theory" is Dean Norris, who will portray a no-nonsense Air Force representative who's interested in using the boys' quantum gyroscope project for military applications. Norris' Captain Williams character will appear in the first three episodes of Season 10, according to a separate report from EW.
Sheldon and Amy (Mayim Bialik), meanwhile, will likely move in together given that they finally consummated their relationship in Season 9. Molaro told EW that the couple's relationship will face "some big experiments," with Sheldon understanding "what this move means" despite not being able to decipher social cues.
Molaro said Sheldon and Amy will "work their way through" the next step of their relationship "like they have for the last six years." Sheldon and Amy living together full-time also means that Leonard and Penny can finally move in together as well after tying the knot in Season 9. "The Big Bang Theory" Season 10 premieres on Monday, Sept. 19 at 8 PM ET on CBS.
