‘Big Bang Theory’
Penny (Kaley Cuoco) and Leonard (Johnny Galecki) won't stay mad at each other for long in “Big Bang Theory” Season 10, episode 13. CBS

CBS has released a series of photos teasing “Big Bang Theory” Season 10, episode 13. Based on the “The Romance Recalibration” pics, there will be trouble in paradise for Penny (Kaley Cuoco) and Leonard (Johnny Galecki). In order to fix their issues, Leonard will seek Sheldon’s (Jim Parsons) help in coming up with a relationship agreement for him and Penny.

In one of the photos (via TV Fanatic), Penny and Leonard appear to be furious as they argue about something seemingly petty. Another photo shows Leonard seeking comfort from Sheldon by engaging in a game of chess with his best friend.

Meanwhile, another teaser photo shows Sheldon talking to his girlfriend, Amy (Mayim Bialik). One snap reveals that they are in the room with Penny and Leonard. In their attempt to encourage the husband and wife to address their issues, Sheldon and Amy share a sweet kiss. Unfortunately, the couple doesn’t think that kissing will resolve their marital woes.

Meanwhile, since Penny and Leonard are feuding, the former will ask Amy to accompany her on a spa weekend. One image shows Amy looking uncomfortable while sitting on the bed. Penny doesn’t look very happy either since going on spa dates is what she usually does with her husband. Penny and Amy’s spa date will be interrupted by Leonard and Sheldon’s arrival. Towards the end of the episode, Penny and Leonard finally get the chance to talk over a glass of wine.

Elsewhere, Howard (Simon Helberg), Bernadette (Melissa Rauch), Raj (Kunal Nayyar) and Stuart (Kevin Sussman) are all busy organizing Hallie’s bedroom. After finishing the nursery, Raj and Howard will have a heart to heart talk in episode 13.

“Big Bang Theory” Season 10, episode 13 will air on CBS on Jan. 19 at 8 p.m. EST.
