- Not to be confused with the deaf Emily who also dated Raj in the season 5 episode The Wiggly Finger Catalyst.
Dr. Emily Sweeney, M.D., is a dermatologist who found Raj through his dating site and contacted him. Raj replied through Amy. Emily is a redhead with a quirky sense of humor and likes horror movies and other gory things. She has three tattoos including a Sally rag doll from the Disney movie "The Nightmare before Christmas". As of Sept. 2015, Emily has been on more episodes than Wil Wheaton or Raj's parents, is tied with Priya and is behind Barry Kripke, Mrs. Wolowitz and Stuart. In October 2015, she was added to opening credits when she appears in the episode like Kevin Sussman.
In "The Friendship Turbulence", after Amy has Raj check his dating site, he finds a message from a woman named Emily who wants to meet him. The reluctant Raj has Amy contact her as his wing-man. Amy and Emily exchange emails and find they have a lot in common. They both went to Harvard University, are doctors, and like crocheting and Chaucer. Unfortunately Emily doesn't like Raj's inability to correspond with her directly. Amy and Emily meet to have coffee and Raj barges in to show that he is not a passive guy. Emily calls him a weird guy with no boundaries and leaves. She also ditches Amy for their next get together. Raj appeared to ruin any chance for friendship for either of them.
In "The Indecision Amalgamation", Raj meets Emily again in the coffee shop and apologizes. She gives him another chance and agrees to go out to dinner with him. Then Raj finds out that Lucy wants to see him again and he finds himself dating two women. Emily is fine with that, unlike Lucy. Raj and Emily seem to be getting along together. She also has a creepy sense of humor that Raj likes.
In "The Relationship Diremption", Raj and Emily have dinner with Howard and Bernadette. Howard figures they should do it quickly because Raj is bound to mess up his relationship very quickly. Upon meeting Emily, Howard recognizes her because he had a blind date with Emily sometime near 2009 before he met Bernadette. He had a sick stomach, had to use the bathroom and clogged the toilet. Since he was too embarrassed to tell her, he escaped through the bathroom window just like Lucy. They meet again at dinner where she is now dating Raj. Emily reveals she's okay with it and her friends love the story. They call him "Clogzilla".
In "The Anything Can Happen Recurrence", Raj and Howard watch the gore-fest "House of 1000 Corpses" because Emily wants to watch it with Raj. They are both turned off and wonder about someone who likes this type of movie. On their date, Raj tells Emily how he feels about it and she also wonders about someone who likes this film. She also admits that it turns her on, so Raj immediately starts it so they can watch it.
In "The Gorilla Dissolution", Raj and Sheldon find Emily at the movies with another guy. Later she visits him to talk. The guy was her tattoo artist who had been asking her out for weeks and she did so just to end the obligation. She mentions one tattoo on her shoulder, one that is not on her shoulder and one that is REALLY not on her shoulder. It has been a long time since Raj has seen something REALLY not on some woman's shoulder. Emily suggests that if he'll show her his pierced belly button, he can see all her tattoos. They start to kiss and she then spends the night.
In the next episode, "The Status Quo Combustion", the gang was happy about how serious his relationship with Emily has gotten, though she did not appear in the episode.
In "The Hook-up Reverberation", Penny and Leonard meet Emily for the first time and she treats Penny rather coldly. At Bernadette's suggestion, Penny stops by Emily's office to do her sales pitch in front of a real doctor. Penny does her pitch enthusiastically; however, Emily ignores her. It's then revealed that she doesn't like that Penny had crawled into bed with Raj. Though Penny is mad at Raj for telling Emily about their "one-night stand", he gets them together and they apologize to each other. After they part, both women say how much they hate the other one.
In "The Prom Equivalency", Emily is Raj's date to the prom-themed dance put together by Amy and Bernadette. She travels to the dance in the couples' limo. Bernadette likes her Sally (From "The Nightmare before Christmas") tattoo. She likes Sally because she has lots of scars and her limbs had to be sewn back on. She also tells Bernadette that in the original Cinderella story, (Bernadette's favorite fairy tale) that the evil step-sisters cut off their toes to fit in Cinderella's glass slipper. Also while Stuart and Howard are fighting, she tells Raj that she is having a great time. Emily has two other tattoos.
In "The Anxiety Optimization", Howard starts a game called "Emily or Cinnamon" where people have to guess whether statements Raj has made are for the woman he loves or the dog he loves. Emily thinks Raj's sensitive nature is very sexy.
In "The Intimacy Acceleration", Emily gets Raj, Leonard, and Amy to go to an event escape room where puzzles have to be solved to exit the room. Unfortunately, the puzzles don't prove to be very challenging to the four, who all have advanced degrees, and they get out in only six minutes. The four of them later give Sheldon a make-shift surprise party after Penny tells them it's his birthday.
In "The Colonization Application", Raj snoops around Emily's apartment place when he is alone and breaks her bedside drawer. Emily is not happy, but forgives him. When she gets back she tells him it's good that he didn't look in her closet causing Raj to wonder what was in it.
In "The Commitment Determination", Raj confides in Howard and Bernadette how different he is from Emily and that he is considering breakup with her though he has a fear of being alone. Howard doesn't believe that he will break up with a girl that has sex with him. At a grave yard picnic, Emily picks up on these vibes and tells Raj that he has to break them up and not make her do it. Instead, Raj tells her that he was just trying to say that he loves her and kisses her, not knowing what her reaction would be.
In "The 2003 Approximation", Raj played Emily the song that he and Howard wrote for their band. She thought it was cute, but would rather hear something she could dance to. Raj relays this opinion to Howard and it almost breaks up their band. Emily is later seen with the rest of the gang (minus Amy) at the comic book store hearing Howard and Raj perform their song.
In "The Platonic Permutation", she joined Raj in serving Thanksgiving dinner to the homeless in a soup kitchen. Bernadette acknowledged that they were close enough that she could call her husband creepy.
In "The Empathy Optimization", Emily is infuriated by a sick Sheldon like everyone else. She is angered when Sheldon tells her to remove the "irrtating patch of brown skin" standing next to her. When Sheldon tries to apologize, she does NOT accept his apology due to him inadvertently insulting her and he later makes her cry attempting to apologize again. Eventually, Sheldon makes a heartwarming apology to Emily, and she finally forgives him, allowing Sheldon to join all of them on their party weekend.
In "The Valentino Submergence", Raj breaks up with her because he wants to pursue Claire. Emily is thoroughly disgusted with him. After Claire turns him down, he asks to get back together with her. Emily slams the door in his face.
In "The Application Deterioration", Emily sends Raj a belated Valentine's Day gift: a sextant (which she got for him before the breakup), also calling to say that she still wants to be friends. Later on, Raj gets calls from both Emily and Claire. Emily just wants to talk. Claire advises him that she is just manipulating him. He ends up at Emily's to just talk because she is so upset, but they end up in bed. Raj remarks, "Good talk."
In "The Hot Tub Contamination", Raj admits that he has broken up with both girls at the ladies' insistence.
Nothing really has been talked about Emily's family members. It's unknown if she has any siblings or not and where her parents are; however, in "The Commitment Determination" (S8E24), Howard hints that Emily's father has died when he says "Well, if it’s her father’s grave and they didn’t get along, then you know she holds a grudge." when Raj talks to him and Bernadette about his relationship with Emily. Whether this was just an example from Howard and is not exactly dead, but alive or if he really knows that Emily's father is dead and found out off-screen is unconfirmed and unknown.
