- Raj meets a girl at the Planetarium, but soon after finds out she is married. Sheldon rents out his old room to use for his work.
- Raj is finishing up his planetarium show to an audience that includes a bored Leonard and Howard. A beautiful blonde woman Nell (Beth Behrs) comes up to take a selfie with Raj. He kids around with her telling her that he always does that with beautiful women. He then asks the guys if the handsome gentlemen enjoyed the show. Leonard tells him to turn off the charm, but Raj says that he can't.
At the cafeteria, Howard shows a cute picture of Halley in the bathtub. Sheldon has pictures of the new equations he has been working on. Raj has a picture of him and Nell, the girl he met at his show, at 2:30 in the morning. He has another date with her tonight. Sheldon announces that he has a date ... with string theory.
Amy arrives home and finds Sheldon taking more pictures with his string theory baby. She is happy to see him so excited. Also see can't find a place to sit since Sheldon has his papers scattered all about. She is about to head to the bedroom until Sheldon tells her that he'll quit for the evening to be respectful of her feelings. She asks him if he is trying empathy, which makes him disappointed because he didn't first think of it.
Morning at Nell's apartment, Raj is making omelets. She finds breakfast delicious and says that husband never cooked for her. She has been separated from her husband for about two weeks. Raj is worried especially since her husband is a fireman who knows how to use an ax. Nell says not to worry about it because he moved out and she moved on.
Leonard is testing Penny on the side effects of the drugs she is selling. Sheldon comes in, says "Hello" and disappears down the hallway. The couple hopes that Sheldon remembers that he doesn't live there anymore. Sheldon returns and wants to use his old room in the evenings to do his work without disturbing Amy. Leonard and Penny tell him no to every comment Sheldon makes until they can't deny that they're not going to put a gym in there.
Raj is talking to Howard and a bedridden Bernadette as to whether he should date someone who has only been separated for 13 days. He wants to know if he's the good guy in his movie or the bad guy in their movie. Bernadette thinks that he's the weird guy in their movie. Raj wonders how long they would wait to date if they broke up. Howard doesn't know, but Bernie is sure that it's eight days, two crying and six at the gym.
Leonard is on the phone with Sheldon still saying no about him renting the room. Sheldon insists that they wouldn't even know he was there. Then he proves it because he was in his old room all night. Penny then asks him about his office at work, but Sheldon doesn't want to use because it is not safe at night because of all the raccoon and grad students walking around like they own the place. Sheldon presents a small agreement for him to use the room and not eat, sleep or even use the toilet there. And they will get paid.
At the planetarium, Raj is trying out various pauses to finish his talk with Howard. (...a walk with me...pause...through the stars.) A man enters looking for Rajesh and it turns out to be Nell's husband Oliver (Walton Goggins). Raj says that he is sorry which doesn't make Oliver feel any better. He wants Raj to stop seeing her. Raj says "Fine" and gets ready to leave, when Oliver starts crying. Raj tries to explain that things will get better. He sits down and they start to talk.
Back in apartment 4A, the Hofstadters haven't heard a peep from Sheldon. The fact that he isn't annoying worries Leonard because he lived with Sheldon for ten years. Penny wonders why not driving Leonard crazy is driving him crazy. He compares it to Godzilla having Arby's instead of Tokyo. He goes to talk to Sheldon who hopes he wasn't being too loud. Then Sheldon wants to know if Leonard wants him to be a less considerate tenant. Yes. No. What? Leonard goes back to Penny who did find an Arby's in Okinawa.
Back in Bernadette's bedroom, Raj is telling them Oliver's life story and how he met Nell at the DMV. It was love at first sight. Raj had taken him to the House of Pies for dessert. Bernadette suggests that he stop seeing her. Howard is annoyed that Raj went to House of Pies and shared half a pie with another man other than himself.
Leonard goes over to talk to Amy who was expecting Sheldon. Leonard can't deal with Sheldon as a calm rational person. Amy says that he can send him back because she misses him. Unfortunately she can't ask him to return because he is being so respectful of her.
Raj and Nell are making out when he starts to see an image of Oliver talking to him. He can't keep kissing her with Oliver in his head. Raj mentions that he met her husband. First she thinks that he tried to track him down, but Oliver did the tracking down. She found Oliver possessive and jealous, but Raj found him very comfortable. Raj tells Nell that she wasn't being fair to him and that he said he would go to counseling with her. What? Nell calls him crazier than Oliver. Raj then adds, if it doesn't work out, he would still be up to sleeping with her. Either way she gets herself a fellow. Nell looks disgusted and walks away.
Leonard presents Sheldon with his rental agreement and using the three day trial period, he wants Sheldon out. Unfortunately the time period has elapsed and Sheldon now has the option to continue and presents Leonard with an even longer new rental agreement. Even though the agreement is blank, he challenges Leonard to get a lawyer. And Leonard has to supply him with lemon flavored sparkling water. "Go get some. Chop, chop." Leonard tells Penny that Sheldon is not leaving and that he has to go get him a drink. Penny wants to know why Leonard is smiling. He feels much better at being annoyed by Sheldon than not.
Finally Oliver shows up at Raj's show and calls him, "Buddy." He visited Nell and she is giving him another chance. Raj thinks that that is great and wants to go to House of Pies to celebrate. Oliver wonders if he should call Nell and Raj doesn't want to.
Title reference: A double Entendre that refers to both the love triangle between Raj, Nell, and Oliver, who is upset at his separation from Nell, and the roommate triangle that has reformed between Sheldon, Leonard, and Penny, a distinct callback to the show's initial seasons.
