Amy: Outstanding. Amy: What's that like? And not in the sink. Barry and Zack are doing backing vocals. Bernadette: Pick out the hottest guy in the room, take him home, do unspeakable things to him, then kick him to the curb with a smile on his face and teeth marks on his heinie? He'll be back. Hi, Amy. Howard: Yeah. I think it's time to face the fact that Leonard is the nucleus of your social group. Just because Leonard has a new girlfriend does not mean I need to go out and hook up with some guy. LeVar Burton's coming here? Leonard: He kind of does. Leonard: I'm having dinner with Priya at Raj's. Next thing I know, this beautiful chick shows up, drunk out of her skull, wants to get in with me. Now, what exactly are toes? Penny: Okay, I'm not upset about Leonard and Priya. Penny: So, where do you guys want to go dancing? She is staying with Raj. Sheldon: But change is a part of life. Sheldon: But what if he does? Sheldon: Leonard the nucleus? Sheldon: Of course. Sheldon: That's very nice, Stuart. Sheldon: When he finished, he shouted Eureka! Stuart from the comic bookstore, Barry Kripke from the university, Penny's ex-boyfriend Zack and TV's LeVar Burton. That means you're all probably gonna be hanging out there more. When last we spoke, you were going to take a taxi home from Raj's, but according to Facebook, you just checked in at the Cheesecake Factory. You realize that's the first time we've ever done that without having to listen to Sheldon tell us why it's called a toast? Zack: Anyway, after we get done snowboarding, I go back to the lodge and get in the Jacuzzi.

Summary: Now Leonard and Priya are dating and since she lives with Raj, Leonard and Howard decide to have dinner there instead of the normal venue which disturbs Sheldon. Sheldon stops by the Cheesecake Factory where Penny tells him he has to accept that the gang will be hanging out at Raj's place more often. Amy tells him that Leonard is the nucleus of their social group and not Sheldon. As a result, he sets up a new group consisting of Kripke, Stuart, Zack and LeVar Burton (whom he tweeted) with him as the nucleus. Sheldon's plans are dismissed by the others in favor of Zack's dating stories and getting drunk and singing karaoke. Naturally, Sheldon does not like that very much, so he decides to go back to his old friends, who, in the meantime, realized that they actually missed Sheldon. In the end, LeVar Burton finally does show up at Sheldon's place, but when he sees Kripke, Stuart and Zack singing karaoke together, he leaves immediately. Meanwhile, Bernadette and Amy want to take Penny out dancing to get her mind off of Leonard and Priya. As she changes clothes, she tells the girls that it is the first time in her life she is satisfied with being single and does not want to have sex with a random guy to make up for it, however when Amy finds the encased snowflake that Leonard gave to her after his expedition, she changes her mind as her feelings for Leonard come back to the surface again.
