‘Big Bang Theory’ Season 10 Spoilers: Why Did Penny, Leonard Fight Again In Episode 14? [RECAP]

Penny (Kaley Cuoco) and Leonard (Johnny Galecki) had another fight in the latest episode of “Big Bang Theory.”

In “Big Bang Theory” Season 10, episode 14, titled “The Emotion Detection Automation,” the couple once again had a major fight. But this time around, their argument revolved around Penny’s brother, Randall (Jack McBrayer). Leonard found out that Penny was helping her brother find a job. The former was hesitant about the idea because Randall used to be a drug dealer. When Penny told Leonard that Randall may stay with them indefinitely when he gets hired, Leonard got even more upset because it seemed as though Penny has already made a decision without talking about it with him first. When Leonard told Penny his real feelings, the latter got upset and retorted that he doesn’t tell her everything either.

But in true “Big Bang Theory” fashion, everything ended well for the couple. After patching up their issues, they apologized to Sheldon (Jim Parsons) for hurting his feelings. Sheldon used an emotion detection machine to help him understand how other people are feeling, but he and Amy (Mayim Bialik) went overboard when they made fun of Penny and Leonard during their fight. While using the machine, Sheldon found out that Leonard was angry over Penny’s decision to help Randall. When Penny discovered the truth, she got upset with Leonard for not supporting his brother-in-law.

Elsewhere, Raj (Kunal Nayyar) finally learned the real reason why his relationships keep failing. As it turned out, Emily (Laura Spencer), Emily (Katie Leclerc), Lucy (Katie Micucci) and Claire (Alessandra Torresani) all had the same sentiments about him. Toward the end, Raj felt bad about himself, but his best friend Howard (Simon Helberg) reminded him that he loves and cares for him deeply.

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