"The Big Bang Theory" season 10, episode 1 will premiere sometime at the end of this month, and details from the first installment have already been leaked online.
The show's official spoiler site confirmed that the title for episode 1 is "The Conjugal Conjecture" and it will revolve around the events that will take place before, during and after Penny (Kaley Cuoco) and Leonard's (Johnny Galecki) wedding.
According to the site, the first scene in the episode will feature Penny, Leonard and Sheldon (Jim Parsons). The latter will be calling Leonard while he's in the middle of his sleep to say that he could be brothers. After all, there are rumors that his mom Mary and Leonard's dad Alfred hooked up before Penny and Leonard's wedding day.
"Leonard, you and I could be brothers," Sheldon said.
Leonard will shut Sheldon's thoughts down by saying that he is ridiculous since they can't and won't ever be brothers or step brothers.
"Good because a grown man living with his brother and his wife would be kind of weird," Sheldon replies.
Meanwhile, the episode will also see an awkward encounter between Sheldon, Mary, Beverly, Leonard, Alfred and Penny.
While at their apartment, Sheldon will confront Leonard's dad to ask if he had sex with his mother.
"So, did you defile my mother?" Sheldon asked Alfred.
"I can assure you we only had drinks and pleasant conversation," Alfred replied.
"So did anyone say your genitals are a sight to behold?" Sheldon continued to ask Leonard's father.
"That was absolutely not said, and no one would ever say something like that!" Alfred replied.
At this point, Sheldon said that he was once told that his genitals looked good.
In other news, "The Conjugal Conjecture" will also feature the arrival of Penny's family members. Penny's mom Susan (Katey Sagal) and Randall (Jack McBryer) will attend the former's wedding to Leonard.
Since Penny doesn't really have a good relationship with the two of them, she will struggle to make sure that Susan and Randall won't make a scene. After all, Susan is divorced from Penny's dad Wyatt, and Randall was once involved in using drugs.
"The Big Bang Theory" season 10, episode 1 will air on CBS on Sept. 22 at 8 p.m. ET.
