The Big Bang Theory” Season 10, episode 7 was a crucial one for Sheldon (Jim Parsons) and Amy (Mayim Bialik), who have been having some issues since they started living together.

In “The Veracity Elasticity,” Sheldon tells his friends that he feels Amy has been hiding something from him, and he’s right. Not only has her apartment been fixed, but she purposely didn’t want to tell Sheldon the truth because she enjoys living with him. To make things worse, Bernadette (Melissa Rauch) already knows the truth about Amy’s apartment and shares the information with Leonard (Johnny Galecki) and Penny (Kaley Cuoco).

At one point, Sheldon decides to confront Amy, but she once again avoids the conversation. Penny also lies to Sheldon about visiting Amy’s apartment, and this left Leonard very confused because they already know that Amy lied in the first place. During their hilarious confrontation, Bernadette walks into the apartment, and an enraged Amy asks her why she had to reveal her secret.

After learning that her apartment has already been fixed up, Amy and her boyfriend discuss if they should continue to live together. Sheldon says that he’s happy to be with Amy, so they decide to stick to their current living arrangement.

Sheldon also has a nightmare in Season 10, episode 7. Since he’s been thinking about his old room, Sheldon dreams that Penny and Leonard transformed it into a sex dungeon. When he woke up, Amy was right there to comfort him.

Leonard and Penny also had a slight issue on Thursday night’s episode. The former discovers that she has been removing his things from their apartment. Luckily, they were able to sort out their problem.

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