Amy Farrah Fowler

Dr. Amy Farrah Fowler, Ph.D., is a neurobiologist, whom Raj and Howard discovered as a possible match for Sheldon through an Online dating service (without Sheldon's knowledge). Amy is from Glendale, California, as revealed by Sheldon in "The Weekend Vortex". She studied at Harvard University (revealed in "The Scavenger Vortex", S7E03), and had a semester in Norway. She also has a doctorate degree in neurobiology ("The Roommate Transmogrification", S4E24). By Sheldon's own admission, she is most like him by any standard. Like him, she has previously avoided relationships (whether romantic or otherwise is entirely unclear), and only participated in online dating herself to fulfill an agreement with her mother that she dates someone at least once a year so she can continue to have access to her mother's George Foreman grill. She has her own apartment in Glendale, California. She also has a five-year plan to become Mrs. Cooper which appears to be working through the eighth season due to them discussing a future and having children together. By the ninth season, Amy wants to take a breather from their relationship and naive Sheldon pushes her so she breaks up with him. Later on in the season, however, the two reconcile and resume their relationship.

History/Early life (Before the show)
Amy was born to Mr. and Mrs. Fowler on December 17th (as proven by Sheldon having a ticket to the premiere on THURSDAY, that being the 17th), possibly between 1979 and 1982. What happened to her father and whether she has siblings are unknown. She has a strained relationship with her mother. She was very lonely and had no friends from nursery school through to graduate school. The closest thing she had to a friend in high school was the janitor whom she regularly had lunch with until his wife found out, called Amy a "puta" (Portuguese for "whore") and made her stop. Only her mother signed her high school yearbook. Mrs. Fowler also paid Amy's cousin to take her to the prom, but he used the money to buy drugs. She did attend the prom, but was only on the clean-up crew and danced with her mop. After high school, Amy went to Harvard and received a Ph.D. in neurobiology.

Personality


Though Amy and Sheldon are very similar, they have some notable differences. She does not, for example, share his love of Star Trek, Star Wars, Indiana Jones, Comic Books or Trains. At first, she does not participate in wearing costumes on a whim like the guys do, though she is excited to wear a couples' costume for Halloween one year and, another time, dresses up as a Star Fleet medical officer in order to increase Sheldon's feelings for her. Amy is more willing to socialize with others than Sheldon. While Sheldon generally refuses to accept the need for intimacy, Amy appears to desire the kinds of friendship she was denied as a child. She is capable of acknowledging that she is part of a group, as shown in "The Zazzy Substitution" when she uses the phrase "my colleagues and I." She also finds people of the opposite sex attractive, although she is initially unable to understand her physical desire for Penny's ex-boyfriend Zack Johnson until it is examined by Sheldon and her.

Additionally, she has less of a problem with physical human contact than Sheldon, as seen in "The 21-Second Excitation" when she, without hesitation, attempted to engage in "harmless experimentation with " with Penny, in "The Love Car Displacement" when she offered Penny to share a room with her and in "The Cohabitation Formulation" when she hugged Penny to comfort her, when Penny got upset over Leonard finding a new girlfriend (Priya). In "The Agreement Dissection", she, albeit under the influence of alcohol, kissed Penny on the mouth and later did the same to Sheldon the same night.

Amy and Sheldon know how each other thinks because when it comes to the game Counterfactuals, only they know the correct answers whose logic is very obvious to both of them. Other people like Leonard do not see how they obtain their answers.

Amy is very blunt and says things that make others feel awkward, though she has developed into a very loyal friend to the girls and a devoted girlfriend to Sheldon. She has low self-esteem, the main reason why she always put up with Sheldon no one else wants to date her. She is also a virgin and so is Sheldon. Sheldon is not in a hurry to lose his virginity, but Amy is considering it. She is also allergic to avocados and likes Chaucer, other medieval poetry, old French movies and writes Little House on the Prairie fan fiction.



Physical Appearance
Amy is 5' 4" (1.63 m), brunette and with greenish-blue eye color. Her wardrobe includes red-frame glasses, cardigans worn over plaid shirts, denim skirts, tights and orthopedic shoes and sometimes jumpers or floral dresses on special occaisions. She also has modest taste in evening attire. Her hair is usually untied. Sheldon describes her by Amy in her hypothetical alternate-reality story as "a cute bespectacled neurobiologist with hair the color of mud" in "The Cooper Extraction".

Penny


In her early appearances, Amy is ambivalent and often condescending towards Penny. After inviting herself to a with Penny and Bernadette, Amy grew closer to them and was less awkward. Amy is no longer condescending to Penny and things eventually got to the point where she considers Penny to be her best friend (or "bestie" as she took to naming her). Penny is the person mainly responsible for Amy's improving social skills, introducing her to drinking and other normal activities such as dancing, shopping, hanging out with friends, gossiping and trash-talking.



Amy values her relationship with Penny very highly. In "The Infestation Hypothesis", after Penny found out that Sheldon had manipulated Amy to influence her to get rid of her chair and got mad at Amy, she desperately tried to take it all back by sitting in the chair and was promptly bitten by a an unknown creature living in it. Penny is nice to Amy because she feels some mixture of pity and sympathy, and does what she can to help her socially. Amy likes the arrangement and sometimes would rather hang out with the girls than Sheldon himself. Amy admits that her whole female social life revolves around Penny and that even if she gets mad at her, it wouldn't last. On one occasion, when Penny accidentally offends Amy by hiding a gargantuan and rather unflattering painting of hers, Penny rushes over to Amy's apartment to rescue their friendship and rehangs the painting in her apartment.

In "The Speckerman Recurrence", Amy expressed her delight at being best friends with a bully, namely Penny, when the latter was revealed to have been a bully during her high school days. Penny decided to make amends by apologizing to the girl she once bullied, but was unsuccessful in gaining the apology. In the end, it was Amy who suggested a way for Penny to make amends, by showing altruism in the form of donating her clothes to the needy. In "The Weekend Vortex", after Sheldon upset Amy by choosing an intensive weekend of gaming over accompanying her to her aunt's birthday party, despite already giving his word that he would, Amy confided in Penny and Penny gave her advice on confronting Sheldon. When Amy proved to lack the necessary self-esteem with which to confront him, Penny stood up for Amy and confronted Sheldon for being a bad boyfriend.

Amy occasionally displays signs of a bisexual infatuation or curiosity with Penny, often making inappropriate comments. For instance, when Penny, in an effort to persuade Sheldon to let her cut his hair in "The Werewolf Transformation", asked Amy for her opinion, Amy's response was "There is not a hair on my body that I wouldn't let this woman trim," resulting in discomfort on Penny's part. On another occasion, after kissing Penny on the lips (Amy was drunk), she sings from Katy Perry's song, "I kissed a girl, and I liked it." In "The Pulled Groin Extrapolation", when Amy and Penny were discussing Amy's theory that Leonard had fallen in love with her, Amy told Penny that Leonard did not get her "motors running" and that Penny had a better shot than Leonard. She does recognize Penny's shortcomings and tries to avoid discussing them so they can remain on good terms. In "The Anything Can Happen Thursday Recurrence", Amy did admit to Leonard that she is jealous of the close personal friendship between Sheldon and Penny and how comfortable he is around her.

In "The Hook-up Reverberation ", Penny wonders how she could get Raj's new girlfriend Emily to like her. Amy says that she could hang around her pretending to be her friend and then before you know it you're in her apartment drinking her wine and eating her food. Penny says that that won't work even though Amy's suggestion mirrors her own relationship with Penny.

Bernadette


Amy is also close to Bernadette, though not as close as she is with Penny (of the three, Amy considers Bernadette to be 'the least cool'). Amy and Bernadette are both biologists and possess doctorates, making them able to converse intellectually. Amy had once called Bernadette a wildebeest, but quickly adds "with hair that smells of strawberries" after Bernadette's reaction showing that Amy cares enough about her to try and compliment a positive quality after insulting her, and is very excited to be a bridesmaid at Bernadette's wedding. Bernadette, though she at times feels that Amy is creepy, values her enough and to make up with her for not asking Amy to join her bridesmaid dress shopping session with Penny, to make Amy her maid of honor. Bernadette is more uncomfortable with Amy's "outside of the box" comments, while Penny is more used to them having been friends with Sheldon.

In "The Speckerman Recurrence", Amy and Bernadette shared the stories of how they were bullied during their school years, with Bernadette's involving a case of having her clothes taken away by Tammy Bockneck and replaced with an elf costume that turned out to be too big for her, and Amy's with having hairy knuckles due to applying hand lotion that had secretly been tampered with Rogaine by her bullies. They were not surprised when they found out that out of the three girls, Penny was the only one who left high school unscathed, as she was the one doing the bullying. Bernadette also acts as a kind of translator, translating Amy's words such as "assuage" and "altruism" to versions that are much simpler that Penny can understand. There are often times where her closeness with Penny overshadows Bernadette.

In "The Hofstadter Insufficiency", Bernadette spends time with just Amy at a medical convention. They like getting able to talk shop without Penny around who prefers to talk about boys. While at the bar, two guys send drinks over to their table which excites both of them. Then Bernadette remarks that no one would blame her for following up because her boyfriend is so "Sheldon" making Amy mad. That night they make up and bond over having been hit on. Ironically, when asked which guy they would have liked, each of them chooses a guy more like their other friend's better half.

In "The Focus Attenuation", Bernadette and Amy go out partying in Las Vegas while Penny stays in her room studying for her job. They return quite drunk urging Penny to join them at a male strip club. Amy steals Penny's laptop and Bernadette wants to get cozy with the male dancers.

After Amy and Bernadette become better friends from bonding over their mutual love of science, Amy develops a little girl crush on Bernadette and sometimes her curvaceous figure.

After Amy breaks up with Sheldon, Bernadette helps her through it since Penny has been busy as a newlywed. In "The 2003 Approximation", Sheldon asks Amy to become his roommate to replace Leonard who moved in with his wife. She declines; however, she does defend Sheldon when Bernadette calls him a weirdo. Amy finds him brilliant and insightful.

Leonard
Amy and Leonard did not have good first impressions of each other. Amy always seemed to look down on Leonard and Leonard called her judgmental, sanctimonious, and just plain obnoxious. However, their relationship improves gradually. Finally, in "The Pulled Groin Extrapolation", Amy asked Leonard to be her date to a wedding instead of Sheldon. They ended up enjoying each other at the wedding and Leonard commented that Amy really knows how to make a guy loosen up and have a good time. When Amy called Sheldon while drunk in "The Isolation Permutation", Leonard and Sheldon went to see her at the parking lot in front of the liquor store at Leonard's insistence. Leonard ended up being the person helping Amy up and walked with her as they made their way to send her back to her apartment. Amy giggled when she said that he had found "second base". In "The Flaming Spittoon Acquisition", Stuart asked Leonard to be the guy who checks in with Sheldon regarding his response to him asking Amy out. In "The Status Quo Combustion", Leonard let Sheldon go on his train trip and Amy explodes hitting him with a pillow for letting him go.

Howard
Amy's relationship with Howard is somewhat complicated exactly the same way as it is with Sheldon. She, like Sheldon and Dr. Gablehauser, makes fun of Howard for lacking a doctorate and for his other idiosyncrasies; however, in "The Scavenger Vortex," she and Howard spend time alone together for the first time and bond over a mutual love for music, planning concert trips and ending the episode with karaoke. She appears to have more normal fun with Howard than with Sheldon.

Raj
Amy's relationship with Raj is kind of complicated, but they remain friends. Her relationship with him can be described the same way it is with Sheldon. In "The Santa Simulation", the guys choose to play a game of Dungeons and Dragons over plans with their girls, prompting Amy, Penny, and Bernadette go to a club for a ladies night. Raj tags along with them after his D&D character dies within the first five minutes. At the club while the girls are trying to help Raj find a girl, Raj reveals to them that he had a thing for Penny and Bernadette, but always tries to like a friend's girlfriend one at a time. Amy then says that Raj must have had a thing for her, but he responds with a no. Hurt by the comment, Amy reveals past sad experiences about guys, like how one time she passed out at a frat mixer and woke up with more clothes on her, Raj then empathizes with her about his troubles with girls and they smile a little at each other with Amy commenting on her current relationship with Sheldon and how it could happen with Raj and a girl. When they all are about to leave, Amy says that she's good now that she knows Raj likes her and Raj follows out with Penny saying that he kind of likes her now that he knows she's not into him. Improving on the relationship between Amy and Raj now that they both know they are together in the overlooked department of the opposite gender. In "The Friendship Turbulence", Raj asks Amy to respond to a girl that answered Raj's dating site. Though the girl thinks that Raj is too shy and passive, she does strike up a friendship with Amy. After Raj charges in on their coffee get-together, he ruins a possible friendship with Emily for both of them. Amy is the only member of the group that regularly calls him "Rajesh".

Main Article: Sheldon and Amy
Amy first met Sheldon in the final episode of Season 3, "The Lunar Excitation", when they were both matched from an on-line dating site, though the event triggered as a result of Howard and Raj's prank of using Sheldon's profile for the dating site. Though Sheldon disapproved of the reliability of dating sites, he changed his mind upon meeting Amy and the two have been close ever since. Amy can be seen smiling to herself at the counter standing next to Sheldon. It was revealed at the beginning of season 4 that Amy and Sheldon have been communicating daily with each other for about four months, yet they have not met yet, other than the first encounter at the end of season 3. Amy and Sheldon regularly interact via the many different technological portals such as Facebook, Twitter, text messaging, and video chatting. Their relationship grew stronger throughout the entire season 4. For example, they met each other's mothers, they had meals together, she got him engaged in experiments which involved them spreading a gossip that they have slept together, that never happened. Amy and Sheldon are still virgins. He was even there when she had to buy feminine hygiene supplies once. Sheldon described Amy as his friend who is a girl, but not his girlfriend, and Amy similarly described their relationship as boy/friend/girl/friend ("boy slash friend slash girl slash friend"). Their relationship earned them the title "Shamy" from their friends. As the series progresses however, it is implied that their relationship has evolved into non-platonic yet non-romantic in seasons four and five.

In "The Zazzy Substitution", Sheldon revealed that Amy had licked her thumb to remove raspberry jelly from the corner of his mouth. Later, when they terminated their relationship over a dispute about whose area of expertise is superior, Sheldon started collecting cats. He even commented that cats make great companions since they do not argue or question his intellectual authority. His mother uses reverse psychology to help them make up, so Sheldon negotiates reconciliation with Amy.

In "The Alien Parasite Hypothesis", Amy became attracted to Penny's friend Zack. She could not figure that out initially, so she and Sheldon analyzed the symptoms she had when encountering Zack. One of the conclusions was sexual arousal, but based on her personality, Sheldon doubted that and first believed in other illogical answers such as menopause or an alien parasite. When Amy pointed out that Sheldon could have been jealous, he refused to clarify his feelings and decided to finish his lunch at home.

In "The Agreement Dissection", a drunken Amy kissed Sheldon, and although the kiss was short, Sheldon commented on her actions as fascinating. She also gave him good advice on how to handle the problems he was having with Priya regarding her meddling in his Roommate Agreement with Leonard.

In season 5, their relationship seems to have grown even stronger. While in season 4's "The Desperation Emanation", Sheldon gave his blessings to Leonard to date Amy, in season 5's "The Pulled Groin Extrapolation", when Leonard unknowingly insinuated that he and Amy had had sex, Sheldon karate-chopped him and said, "She is not for you!"

In "The Isolation Permutation", Sheldon grew extremely worried when he could not reach Amy and discovered that she was upset at being left out by Penny and Bernadette on their bridesmaid dress shopping expedition. Sheldon, however unwillingly, ended up cuddling on the couch with Amy after an exchange of counter-offers which included sex, a pat on the head,, and neck massage.

In "The Ornithophobia Diffusion", Amy hinted jealousy at the sight of Sheldon being all sweet and infatuated with a bird he called his "little Lovey-Dovey". Amy also suggested early on that in order for Sheldon to get over his fear of birds, he needed to interact with it, just like how he did with the mailman, showing how familiar she is with his personal life.

The turning point in their relationship is in "The Flaming Spittoon Acquisition." When Stuart asks her out for coffee, Amy agrees since she finds Stuart nice and funny. She was also influenced by both Penny and Bernadette; Penny advised her that after over a year being with Sheldon and with nothing really going on, it is fine for her to look around, and Bernadette agreed since Amy and Sheldon are not engaged. Her date prompted suppressed jealousy from Sheldon, and after talking with Penny, Sheldon ended up interrupting their date at the movies. Amy told Sheldon that given their relationship status, she is free to do whatever she wants, even if her actions get Sheldon's disapproval. Sheldon responds that he is willing to change their relationship status, with the stipulation that nothing changes physical or otherwise. He indirectly then directly asks Amy whether she is willing to be his girlfriend, and she agrees. Sheldon leaves immediately afterwards. Later, outside her apartment, Amy had a nice conversation with Stuart. Sheldon knocks from inside and tells them to wrap things up. Sheldon then introduces the Relationship Agreement to her and though she thought it was romantic, she did find the terms restrictive, to which Sheldon told her to get a lawyer if she wants to. Amy agreed to the terms and as of that point, they are officially a couple.

In "The Shiny Trinket Maneuver", Sheldon and Amy revealed that their date night is once a month on every second Thursday or the third one, in a one with five Thursdays, as per The Relationship Agreement. They had their first "couple's fight" when Sheldon did not show any interest in Amy's big news, that her article was to be featured in a distinguished journal. Instead, Sheldon was more invested in the fact that he just reached 100 followers on Twitter. Upset, Amy left the date. Sheldon was oblivious to what happened until Penny told him that as Amy's boyfriend, he needs to be excited by the things she is excited by, even if he is not.

Leonard tells Sheldon that he can buy Amy's affection, and he agrees. He gets Penny to help him pick the perfect gift at a jewelry store. Once they buy it, Sheldon has Penny call Amy over to her apartment so he can talk to her. When Amy arrived, she was still upset and voiced out that she does not want to talk to him. However, upon opening her gift, which turned out to be a tiara, Amy became giddy and excited and asked Penny to put it on her. She ecstatically kissed and hugged Sheldon, signaling she was no longer upset. Sheldon hugged her back, but acknowledged that a tiara was a bit too much.



In "The Beta Test Initiation", Sheldon decided to create his own podcast show on vexillology, the study of flags and related paraphernalia. Amy volunteered to be his assistant on the show, acting alongside him, providing ideas to better the show, and dressing up as a pretzel when Sheldon was explaining the Bavarian flag. There was a part during the recording of the first episode of Sheldon's show that Amy patiently acted her part over and over again, since Sheldon mentioned Take 47 at one point. When Amy made a suggestion to put a face on her "surrender" flag to attract younger viewers, Sheldon called her idea brilliant, showing that they are on the same wavelength.

In "The Vacation Solution", Sheldon decided to spend his forced vacation working with Amy at her laboratory. Despite his intelligence, and her excitement at being able to work with him, calling it romantic, Amy remained professional and gave Sheldon simple tasks that could be done by an average person, simply because Sheldon had no previous exposure to biology, and is not used to working in a laboratory like hers. Sheldon however, failed to perform any of the tasks satisfactorily, despite complaining that those tasks were below his ability. He even, at one point, accused Amy of purposely giving him menial tasks for fear that he could easily be better than her, since he is smarter. The two got into a heated argument, with Sheldon being his usual condescending self. Annoyed, Amy let Sheldon attempt the work she was doing, which is slicing the. Sheldon accidentally cut his finger and passed out. He was kicked out of the laboratory. Later, after talking to Penny, Sheldon came back to the laboratory and apologized for his behavior, though he attempted it several times since Amy wanted a real apology and he refused to do so. He finally gave in and she allowed him to work in the laboratory, asking him to continue washing the beakers since they were still dirty. Sheldon will compromise more with Amy than with anyone else even to the point of apologizing.

In "The Weekend Vortex", Sheldon promised to go to Amy's Aunt Flora's 93rd birthday party; however, when the guys announced that they will be having a 48-hour Star Wars online gaming marathon; Sheldon had a change of heart. Amy demanded he keep his word as she followed all the protocols stipulated in The Relationship Agreement regarding traveling. After some arguing and failing to find a loophole, Sheldon agreed to join Amy. The next morning, Amy told Sheldon how grateful she was that he decided to honor his commitment to her. The only reason he was going, however, was because he planned to join the online gaming while at the party. Upset, Amy said that if gaming was more important to him than accompanying her to avoid the embarrassment she would face, he could stay. Sheldon did not get her sarcasm and used it as an out to stay, even telling her to bring back a slice of cake for him. Amy went ahead and as expected, had an awful time with her family regarding her absent boyfriend. She sought Penny's advice on the matter and they barged into Sheldon and Leonard's apartment while they were gaming, to create a scene. Amy wasn't good enough at lying to cause much ruckus, so Penny told him that how he stood her up had hurt her. Sheldon thought he understood why she was upset, but of course his reasoning came from an egotistical place. He offered her Cooper Coupons to make it up to her. Amy accepted the concession and was actually excited by some of the offers in the coupon book.

In "The Launch Acceleration", Amy, inspired by the progress of the relationships of her friends, decided to make Sheldon develop feelings for her. She used her skills in neurobiology and knowledge of humans' emotional attachments, as well as her knowledge of Sheldon's likes and dislikes, in an experiment to achieve her goal. She started off by holding their monthly date night at her apartment. When Amy voiced out her desire to progress their relationship, Sheldon was quick to refuse it, since he thought they were already moving quickly. He was skeptical she could change his mind, but humored her because he might find her experiment amusing. Amy anticipated his reaction and wasn't deterred. She turned on some "romantic" music: the Super Mario Bros' theme song, Sheldon's favorite from his childhood. He told her it was not going to work, but could not help himself from humming along to the tune. For dinner, they had a few more of his childhood favorites: and spaghetti with sliced hot dogs. He was excited and happy against his will. Sheldon confided in Leonard that Amy's efforts to get him to increase his feelings for her were working, and it was distracting him. He wondered if such thoughts could be stopped. At the end of the episode, Leonard caught Sheldon and Amy playing doctor, Star Trek-style. Amy even dressed up in a Star Trek medical uniform despite her previous rule against dressing up in costumes.

In "The Countdown Reflection", Amy told Bernadette that she thinks Sheldon's eidetic memory is sexy and even made him recite the ingredients in a can of Pringles. Later when Howard and Bernadette tried to get married at the City Hall, Amy asked Sheldon if being there made him think, but it went over his head. She was disappointed when Sheldon was addressing the bride and groom and told them he hopes that they will find happiness together just as he has found happiness alone. Later however, to her surprise, Sheldon grabbed her hand as Howard was launched into space.

At the beginning of season six, Amy and Sheldon are shown regularly dating each other. In "The Date Night Variable", Sheldon invites Raj along for their second anniversary dinner much to Amy's annoyance. After Raj leaves, Amy demands from Sheldon a statement from the heart or she was leaving him. Sheldon paraphrased romantic dialogue from the, and Amy accepts it.

In "The Decoupling Fluctuation", Amy confides to her girlfriends that she plans to marry Sheldon in four years, but still believes him a flight risk. At the movies, Amy requires Sheldon to hold her hand though Sheldon thinks the idea is silly and unhygienic. In "The Habitation Configuration", Amy is directing an episode of Fun with Flags guest starring Wil Wheaton. While not liking his acting, the two get into an argument and Amy leaves. Sheldon is first caught in the middle and then naively thinks that Amy is solving the problem by leaving. He eventually learns that he should support Amy in disagreements.



In "The Parking Spot Escalation", Amy backs up Sheldon in his fight for Howard's parking space, helping him put his name back on the space and leaving her car parked in it.

In "The Fish Guts Displacement", Sheldon finds Amy has the flu and she asks him to take care of her per The Relationship Agreement. First Sheldon says that that is meant for her to take care of him and then leaves. Moments later, Sheldon says that he cares about her well-being so he will take care of her, though he wants to get through it quickly. His plan for her treatment includes putting a rag on her forehead, singing to her (probably "Soft Kitty"), and rubbing Vick's vapor rub on her chest. Sick Amy sits up surprised and wants to start with the Vicks. Sheldon, of course, does not realize the sexual implications. Amy milks the situation for a few days after she is healed, but she is found out when takes a throat culture from her which says that she is no longer sick. Amy apologizes. Sheldon is disappointed because he thought their relationship was based on trust and mutual respect. He says that she needs to be punished so that that it doesn't happen again. He decides to spank her, which she seems to enjoy. Someday, Amy hopes to have a full relationship with Sheldon including physical intimacy.

In "The Bakersfield Expedition", she develops an interest in and debates the physical properties of Thor's hammer with the other girls. Her, Bernadette's, and Penny's interest in comic books excites the boys.



In "The Cooper/Kripke Inversion", he and Kripke exchange papers concerning a theory they are both researching. Sheldon is distraught to find that Kripke's paper is much better than his and allows Amy to hug him. When Kripke explains that the reason his paper is better than Sheldon's is because Sheldon is having sex with Amy and, therefore, has less time to work on the research, Sheldon doesn't correct him. He continues to use his "sexual exploits" as an excuse, though later admits to Penny and Leonard that he does not rule out the idea that he might engage in coitus with Amy sometime in the future.

In "The Spoiler Alert Segmentation", Leonard moves out and Amy tries to convince him that she would be his ideal new roommate. She is familiar with all his habits and his personality quirks that others find rage inducing. Sheldon is uncomfortable with increased intimacy with Amy and also learns from Penny that she doesn't want Leonard to move in with her. Sheldon finally tells Amy that she can't move in and that it's Penny's fault. Amy confronts Penny who tells Sheldon why he didn't tell Amy that he didn't want her to move in instead of blaming it on her. Amy calls Sheldon a coward, which he agrees with. In "The Tangible Affection Proof", Sheldon has Alex buy Amy a Valentine's Day gift and she does such a great job with the third option, the signed brain cell print that Sheldon keeps it. Amy shows up after canceling their romantic dinner and tells him that they'll eat pizza and watch one of his Star Trek/War movies since that is what he really loves. Sheldon shows Amy that she is now his emergency point of contact at the university which sends Amy into tears. He really trusts her.



In "The Love Spell Potential", after Amy was upset about the notion that their characters should have sex, as it was not going to happen in real life, Sheldon was sent to comfort her. Although initially unwilling, he listened to her complain about how the others thought their relationship was a joke. Sheldon doesn't think that. Amy asked him if they would ever have an intimate relationship. Sheldon told her before he met her; he wasn't interested in being intimate with anyone. Amy prompted him to see if he felt any differently now, and he admitted it was a possibility between them. This confession didn't really cheer her up, so he explained to her, that although it didn't feel like it to her, to him it did feel really intimate. Amy knew how he felt, but always wishes they could have more. Sheldon managed to cheer her up by pointing out that they had only known each other for three years and they were already in bed with each other (technically sitting on Sheldon's bed). Amy said they should go back to the others, but Sheldon stopped her, and very calmly pointed out that as they had had a love spell put on their characters in the game, it would only be right to carry it on. And so alone in his room, away from all others, he allowed her to experience a form of virtual intimacy, using a dice to decide what to do next. Upon getting a throw she didn't like, he was willing to break the rules and throw again (which for him is quite impressive).

In "The Raiders Minimization", Sheldon shares with Amy one of his favorite movies, "Raiders of the Lost Ark". She enjoys it, but points out a major error in the movie. Since she spoiled the movie for him, and ultimately the group, Sheldon tries to spoil something that she likes. They start watching her childhood favorite show, "Little House on the Prairie", and he keeps pointing out inaccuracies. She quickly picks up on what he is doing and tells him that since they are in a relationship, he should tell her when he is angry with her instead of seek revenge. They both apologize, though he still tells her what is wrong with the comic strip Garfield, showing that while he's changed a lot with her, he can still be childish.

In "The Workplace Proximity", Amy starts working on an experiment at Caltech which does not bother Sheldon at first. After Howard's comments how he would not want to work all day near Bernadette, Sheldon withdraws his approval though Amy still plans to work there. Embarrassing Amy in front of her co-workers at lunch with inappropriate ethnic comments and talking about the status of their relationship, Amy is extremely unhappy with him. Late at night he comes to her apartment to apologize. He calls her something of a weirdo. They do manage to say that they like each other quirks and all. Sheldon then ruins the moment by adding that she should like him since he doesn't see anyone else knocking at her door.

The two had a friendly conversation, which ended well. Stuart then proceeded to ask Leonard whether Amy and Sheldon are an "item" (couple), prompting a surprise reaction from Leonard, Howard, and Raj. Howard asked whether he is interested in Amy and Stuart revealed that he is, since Amy did not look at him with hatred and contempt, which he finds likable in a woman.
