‘Big Bang Theory’
Will Leonard (Johnny Galecki) be able to make it up to Penny (Kaley Cuoco) in "Big Bang Theory" Season 10, episode 13? CBS

The “Big Bang Theory” will once again go on a short hiatus this week before CBS releases Season 10, episode 13 on Jan. 19.

After “The Romance Recalibration,” Penny (Kaley Cuoco), Leonard (Johnny Galecki), Sheldon (Jim Parsons), Amy (Mayim Bialik), Bernadette (Melissa Rauch), Howard (Simon Helberg) and Raj (Kunal Nayyar) will next be seen in the hit sitcom in February. As of late, it is still unknown why the show will be going on another hiatus.

In episode 13, Penny and Leonard will have petty misunderstanding. The former thinks that he is taking her for granted, so instead of inviting her husband on a spa weekend, Penny asks Amy to accompany her. This will make Leonard realize that he might have done something wrong. Leonard could seek the help of his friends in making Penny understand that he isn’t really setting her aside.

Meanwhile, CBS entertainment president Glenn Geller recently told The Hollywood Reporter that Cuoco's, Parsons' and Galecki’s contracts are still up for negotiations. Even though Cuoco and Parsons previously told TV Line that they are both on board to reprise their roles, CBS still has to finalize their new contracts. The fate of “Big Bang Theory” Season 11 still remains unknown because without the three leads, it’s impossible for the show to continue.

“Contract talks are continuing. It is tough but kind of normal negotiations. We are guardedly optimistic about it. It’s normal negotiations,” he said.

But if “Big Bang Theory” will no longer be renewed after Season 10, executive producer Steve Molaro has already planned an endgame for the sitcom. Unfortunately, he didn’t share his ideas. Instead, he just hopes that the show will be picked up by CBS for Seasons 11, 12, 13 and more.

“Big Bang Theory” Season 10 airs Thursdays at 8 p.m. EST on CBS.
