Are Penny (Kaley Cuoco) and Leonard (Johnny Galecki) already experiencing marital problems? The leaked spoiler reveals that pair will be seeing a psychiatrist when the hit series "The Big Bang Theory" returns for the second half of season 9.

In episode 12 titled "The Sales Call Sublimation," Wikia reports that the newly married couple will be discovering some martial issues after talking to Dr. Sarita Gallo (Jane Kaczmarek). Penny will meet her when she makes a sales call to her office and the latter refused to entertain her. Because of this, she will reportedly ask her husband to pretend to be a client so that they can get her to buy the drugs Penny are selling. Leonard's wife is currently working as a pharmaceutical sales representative, which she started doing in season 8.

Although Leonard is supposed to be the one who will attend the sessions with Dr. Gallo, Penny will also find herself having sit ins with her. The psychiatrist will even tell her she has anxiety issues and that she is serving as a mother figure to Leonard and not his wife. Dr. Gallo will also suggest to Penny that she should ingest the drugs she is selling, but the latter says no, as her company's product may give her "fits of homicidal rage."

Meanwhile, Amy (Mayim Bialik) is away attending a neurobiology conference and Sheldon (Jim Parsons) is missing her. The pair finally took their relationship to the next level after having coitus in episode 11. Viewers will see them talking through Skype in the upcoming episode. To kill time while Amy is away, Sheldon will work with Raj (Kunal Nayyar) to discover a new planet. They will end up discovering a small asteroid, which they will name "Amy."

"The Big Bang Theory" season 9 will return with new episodes on Jan. 7, 2016 at 8 p.m. EST on CBS.
