Lucy is a plain and awkward young woman whom Raj meets at a singles-only Valentine's Day party held in the comic book store. She always feels socially anxious around people she does not know, but tries to force herself into situations that she feels uncomfortable with ("The Love Spell Potential"). She finds it very hard to say no to people, to the extent that she would lie to agree with others. She develops a romance with Raj in season 6, but breaks up with him at the end of the season when he becomes too overbearing for her.
In "The Tangible Affection Proof", at the comic book store's Valentine's Day party specially held for those without a date, Raj makes a speech about how everyone there may not have someone, yet are all a community. Lucy approaches him and compliments him on the speech, and they go off to get coffee together.
In the next episode "The Monster Isolation", Lucy and Raj are having their coffee date at a cafe and seem to be getting along. Lucy excuses herself to use the women's washroom, and ditches Raj and sneaks away from the coffee shop via the bathroom window. The gang soon finds a disheveled and unkempt Raj moping over Lucy's departure, and adamantly refusing to leave his apartment. Later Lucy goes back to the comic book store and gives Stuart a note which contains her phone number. Howard intercepts her and delivers the note to Raj himself. Lucy shows up at Raj's apartment, apologizing for walking out on him and explaining that she has a lot of social problems. Raj says he has some serious psychological problems too, and talks Lucy into having another date with him.
In "The Contractual Obligation Implementation", Raj and Lucy are having a date in a library as they both have social anxiety. While they are face to face with each other, they communicate by texting through their cell phones. Lucy sends a message saying that she works as a web designer. Raj is amazed to read that she designs porn websites, but is reassured that she in fact designs for proms instead, the confusion stemmed from the auto-correct on her phone. Lucy expresses she enjoyed their date, and wonders if she could kiss Raj. She has a panic attack nevertheless and backs out, yet Raj counts that as foreplay.
In "The Closure Alternative", Raj finds Lucy's blog in the Internet where she refers to Raj as "Roger". Her blog also says Raj seemed a little feminine. Howard encourages him to use the blog's content to his advantage. Raj decides to act macho in his next date with Lucy, and she finds him acting weird. Raj tells her he's read her blog and stops his act when she explains that she meant "feminine" in a positive way about him.
In "The Love Spell Potential", Howard comments on Raj's relationship with Lucy as awkward, and Raj says that they have a rule that if no one talks for three minutes, either one can simply hang up. Later they have a date at a restaurant. Lucy tells Raj that she's trying to force herself to do things that scare her, and she is afraid to say no to people. When Lucy finds her food funky, Raj urges her to send the food back. She fails at that and escapes to the bathroom. Then she proceeds to climb out of the bathroom window to get away again, but finds herself trapped inside wire fencing. She calls Raj for help. Raj comes and tells her he finds her very attractive because she has bigger emotional problems than he does. Then they kiss through the space of the wire fencing.
Lucy breaks things off with Raj in season 6's finale "The Bon Voyage Reaction" after Raj tries to convince her to meet his friends, but ends up pushing her too far. She texts him during the going-away party for Leonard, saying that it's too much for her and thinks that they shouldn't see each other anymore. Ironically, she has done him a favor, as the break-up appears to have been the catalyst for a heartbroken Raj to finally overcome his selective mutism towards women.
In season 7's premiere "The Hofstadter Insufficiency", Raj tells his friends wherever he goes, he sees things that look like Lucy's face. To help him snap out of it, Howard helps him meet some new women at a university mixer.
In "The Itchy Brain Simulation", Penny meets Lucy at The Cheesecake Factory and asks her why she broke up with Raj by text message. Penny also tells her that Raj was devastated by her dumping him and that she is a bad person, which makes Lucy cry and leave the restaurant. Later Lucy has coffee with Raj and apologizes for how she broke up with him. Raj hopes that they can get back together, but she tells him that she is seeing somebody else.
However, in "The Indecision Amalgamation", Lucy texts Raj telling him that she misses him. As he is going to have a date with Emily, he wonders if he should see Lucy too. Penny talks him into seeing both women. On his date with Emily, he tells her he is going to see his ex-girlfriend Lucy, and also reveals to Emily that he and Lucy "only went on four dates, hugged twice, kissed once, and there was a handshake loaded with sexual innuendo." Emily is cool with Raj seeing another girl.
In the following episode "The Relationship Diremption", Leonard asks Raj about his dating with two women. Raj says telling Emily seeing another went great, so he tried telling Lucy that too. But Lucy had mixed feelings. Then he told her "Emily was cool with it. Emily's the best. Why can't you be more like Emily?" And Lucy apparently was offended and stopped seeing Raj.
She reappears in "The Emotion Detection Automation", along with Emily (season 5), Emily and Claire to talk about why she ended things with Raj. She is also the only one who's actually sympathetic to Raj about his failed love life. After three years, she has obviously not gotten over her social anxiety, but does have a boyfriend.
