Extended plot
Penny brings in a box for Sheldon from his mother and he tips her a dollar. Sheldon had his s and research he wrote as a child sent to him. Since the verification of the existence of the, the scientist that postulated its existence a half a century ago, , could be heading to a. Sheldon wants to check his earlier work to see if he already hit upon an idea to get his. He needs someone to read through these notebooks since he thinks his time is too important to do the task himself. First he asks Leonard, who declines. Penny volunteers, however she couldn't even understand the title of a paper he wrote at the age of five: "A Proof That Algebraic Topology Can Never Have a Non-Self-Contradictory Set of Abelian Groups". At Leonard's suggestion, he hires a, an attractive student named Alex Jensen. She does flatter him during the interview and thinks it's an honor to work for him. Sheldon makes sure that she doesn't do drugs including, has no hearing loss due an ear infection she experienced years ago, and that she has paid all her s. She is willing to do everything he asks her to do. Leonard felt that she seemed nice and tells her, "May God have mercy on your soul" for working with Sheldon. Raj is attracted to her, but since Raj wouldn't speak to Sheldon and Leonard in front of Alex, Alex wondered what was the matter with Raj.

Penny is giving Amy a which she wants to show Sheldon. Amy tells Penny that if it leads to, Penny will have to leave the room. When Alex answers Amy's to Sheldon, Amy is shocked when she learns that Alex is a girl. Alex tells Amy that Sheldon left a message not to be disturbed unless it's Stephen Hawking, his mother or himself from the future. Alex did take a message. Amy is upset and confides to Penny that while Sheldon told her that he had a new assistant named Alex, he did not tell Amy that Alex was a girl, to which Penny wondered if he even noticed. Amy replies that she is more worried about Alex than she is about Sheldon, especially  when a woman hangs around that wonderful face of his (Sheldon's) for eight hours a day, how could she not fall in love with it. Amy gets Penny to go to Caltech to meet Sheldon's new assistant. Amy bursts into Sheldon's office, but doesn't find him there. Amy leaves her scent to keep Sheldon interested and admits that she's done the same thing in Penny's apartment before they became best friends.

In the cafeteria, Alex brings Sheldon his to his usual exact specifications, but she can't remember if she had taken the stem off the cherry on the bottom. Leonard invites her to sit with them, but Sheldon doesn't want her to, after seeing how servants are treated on a British series (referring to the show ). Leonard still tells her to sit down and impishly tries to get her to talk to Raj about her about s. Leonard continues to kid Raj and Sheldon and she starts getting  (though Leonard ignores it). Amy observes this and tells Penny that she doesn't have to worry about Sheldon, though Penny has to deal with Alex. Penny seems surprised. In her car on the way home, Amy tells Penny that Alex was definitely courting Leonard. Penny says that she isn't worried about her flirting. Amy explains that that is her of her brain talking while her  is telling her that the flirting is happening because he is desirable. Penny again confesses to Amy that she isn't sure how she feels about Leonard. She denies that Alex bothers her, until Amy finally gets her to admit it.

That night while having wine and, Penny keeps asking about his day, however Leonard never mentions Sheldon's new female assistant. Sheldon shows up with Alex, announcing that she may have found what he was looking for in a grade school science project report, A Rederivation of Regarding , that contains a possible new approach for calculating  and could be his ticket to a Nobel Prize. Penny introduces herself. Alex mistakes Penny for his assistant. Penny replies that they were working on a five-year project which confuses Leonard and Sheldon. Alex replies that she is sure that a lot of people would want to work with someone as talented as Leonard. Penny quips that a lot of people can't, and then she takes Leonard to her apartment because her limbic system wants to take his pants off. As Penny is leaving with Leonard, Alex remarks that she seems nice sounding like she has no ulterior motives outside of working with Sheldon.

Meanwhile, Howard tells Bernadette that being cooped up in "this old tin can" for weeks on end is getting to him. He asks her to drop something so he can watch it fall. In another video chat, Howard tells her that due to the delay of the that is supposed to pick up the s, he will have to stay in space for an additional 7-10 days. He is suffering bad s, starts sounding, and gives her crazy ideas on how she can rescue him. He also starts talking to her in code. Eventually, he is given a by the other astronauts, which makes him feel better, though he begins acting strangely afterwards, such as taking off his pants and wind milling in the capsule. Bernadette then tells him to put his pants back on.

Critics
"As I always maintain, the show is at its best when new characters interact with the established eccentricities of the cast. Sure enough Alex's arrival prompts several fun moments...The writers are certainly committed to Howard's space travel and I guess you won’t see anything like it on another sit com. His misery at being kept up there for a long period of time makes perfect sense and I did laugh at his fearful statement that the  “left dogs up here in the 60s!”...This was pretty good. Not funny throughout but by far the best of the season so far." The TV Critic's Review
