When "The Big Bang Theory" Season 10 returns for its 14^th episode next month, Sheldon (Jim Parsons) will showcase a new invention and Raj (Kunal Nayyar) will deal with one of his personal issues. Episode 14 is titled "The Emotion Detection Automation" and details about it have already surfaced online.

In the upcoming "The Big Bang Theory" episode, Sheldon "beta-tests an MIT invention after hearing it can help him read people's emotions," SpoilerTV reported. Leonard (Johnny Galecki), meanwhile, will have a hard time hiding his true feelings when Penny's (Kaley Cuoco) brother, Randall (Jack McBrayer) visits them.

Randall is a drug dealer and ex-con, and Leonard will not be pleased when Penny decides to help her sibling get a job in the pharmaceutical company she works in. A "Big Bang Theory" forum (written by fans who attended the show's taping) revealed that Randall will live with the couple if he gets the job and since Leonard doesn't want anything to do with him, this will escalate to a fight between him and Penny.

In "The Emotion Detection Automation," Raj willingly puts himself in a tight spot when he invites all of his ex-girlfriends over in a focus group. He wants to determine where his relationships went wrong and he's hoping that Claire (Alessandra Torresani), Emily (Laura Spencer), Lucy (Kate Micucci) and Emily (Katie Leclerc) can help him solve his dilemma.

The 14^th episode of "The Big Bang Theory" Season 10 will air on Thursday, Feb. 2 at 8 p.m. ET/PT on CBS. You can watch the promo for the episode in the end of this report.

Raj has dated and pursued relationships with several women since he learned to overcome his shortcomings. In earlier "The Big Bang Theory" seasons, the guy was incapable of talking to girls without drinking alcohol first. But getting past this means entering another problem; his relationships didn't last long and he has been jumping from one girlfriend to the next.

Hopefully, "The Emotion Detection Automation" will change that. Plot leaks from the upcoming "The Big Bang Theory" episode revealed that Raj's ex-girlfriends think of him as a mama's boy, a pushy and a needy man and someone who's too conscious of his physical appearance.

Do you think there's hope for Raj's case? Is Leonard's dislike of Randall reasonable? Sound off in the comments section below!
