Quinn is introduced as the captain of the cheerleading squad (The Cheerios) at William McKinley High School, coached by Sue Sylvester (Jane Lynch). She comes from a conservative Christian family, and is president of the celibacy club. When her boyfriend Finn Hudson (Cory Monteith) joins the glee club, New Directions, Quinn worries about his interaction with the group's star, Rachel Berry (Lea Michele), and joins New Directions herself along with her fellow Cheerios Santana Lopez (Naya Rivera) and Brittany Pierce (Heather Morris). Sue then enlists the three of them to help her destroy the glee club from the inside.
Upon discovering that she is pregnant, Quinn convinces Finn that he is the father, despite the fact that they never actually had sex. Quinn claims that Finn had prematurely ejaculated into her while they were making out in a hot tub. The real father is Finn's best friend Noah "Puck" Puckerman (Mark Salling); he offers to support Quinn and the baby, but she rejects him, saying he is too irresponsible to care for a child. Quinn decides to put the baby up for adoption, and agrees to give it to Terri Schuester (Jessalyn Gilsig), the wife of glee club director Will Schuester (Matthew Morrison), who is faking a pregnancy. When news of her pregnancy is revealed to the school, Quinn is cut from the cheerleading squad and her popularity declines. Her parents kick her out of their house, and she moves in with Finn and his mother. She begins to reconsider giving up the baby, and gives Puck a chance to prove himself, but he is not reliable so she returns to her plan of giving the baby to Terri. Quinn blackmails Sue into letting her rejoin the Cheerios, but ultimately decides against it, preferring to remain with the glee club, where she feels accepted.
Finn learns the truth about the baby's paternity from Rachel, and breaks up with Quinn. Puck again offers to support her, but she turns him down and tells him that she wants to handle the pregnancy by herself. She moves in with Puck's family, but after forming a friendship with fellow New Directions member Mercedes Jones (Amber Riley), Quinn lives with her family instead. She gives birth to a daughter, named Beth by Puck, who is adopted by Shelby Corcoran (Idina Menzel), coach of rival glee club Vocal Adrenaline and Rachel's biological mother.
Having a main character on a popular show with a teen pregnancy storyline turned the phenomenon into a trend in 2010, with other programs and products following.
At the beginning of the new school year, Quinn is reinstated as head cheerleader. She begins dating new glee club member Sam Evans (Chord Overstreet), and later accepts a promise ring from him. When Sue forces Quinn, Santana and Brittany to choose between cheerleading and the glee club, all three initially go with the Cheerios to retain their popularity, but are later convinced by Finn to defect to New Directions. Quinn cheats on Sam with Finn, and Sam dumps Quinn after she lies to him about her time with Finn. She and Finn reunite, and Quinn starts campaigning for junior prom king and queen elections. Lauren Zizes (Ashley Fink), Puck's new girlfriend and one of Quinn's rivals for prom queen, discovers that before transferring to McKinley High, Quinn was known by her first name, Lucy. She was overweight and unpopular, and after slimming down and having rhinoplasty, reinvented herself as Quinn, using her middle name. At prom, Finn is thrown out for fighting with Rachel's date Jesse St. James (Jonathan Groff). Quinn is not named prom queen, and blames Rachel for her loss. She slaps her, but immediately regrets it and apologizes. Finn later breaks up with Quinn when he realizes he has a deeper connection with Rachel.
At the start of her senior year, Quinn has completely reinvented herself and refuses to rejoin either the Cheerios or New Directions, although when New Directions performs "You Can't Stop The Beat" in the auditorium Quinn can be seen watching them with a conflicted look on her face. Shelby lets Puck see Beth, but rejects Quinn's desire to do likewise due to Quinn's bad-girl attitude, appearance and behavior. After seeing a picture of a happy Beth and Puck, Quinn resumes her normal appearance, and Will and the New Directions welcome her back into the club, but Quinn reveals to Puck she is only pretending to behave in order to take Beth back from Shelby, and intends to pursue full custody. After Puck tells Shelby of Quinn's true intentions, Shelby informs Quinn that she does not want her in Beth's life. Quinn later reveals a desire to have a second baby with Puck. Puck refuses, and tries to comfort her; he offers to share an important secret if she promises not to tell anyone, which ultimately results in Quinn planning to get Shelby fired for sleeping with a student, Puck. Quinn decides not to reveal Shelby's secret for Beth's sake.
Quinn advises Rachel to refuse Finn's marriage proposal and leave her past behind. Quinn has done so, and she has been accepted at Yale. Quinn asks Sue to allow her to rejoin the Cheerios, but Sue refuses. However, following Regionals, she changes her mind. Quinn also changes her mind about Finn and Rachel's marriage and supports it. Rachel is reluctant to start the subsequent wedding without Quinn, and texts Quinn. Quinn is responding to Rachel's text when a truck crashes into the driver's side of her car.
Quinn's car accident has left her in a wheelchair, suffering from a severely compressed spine. By "Prom-asaurus" she is able to stand and to walk a few steps in the sessions. When Quinn is nominated for prom queen, Finn agrees to campaign with her, but is outraged when he discovers that she has been hiding the fact that she can now stand for the sympathy vote. When Quinn and Santana count the votes, they discover that Finn has won and so has Quinn. Quinn realizes that the victory means nothing. She and Santana falsely report the prom queen results as a write-in victory for Rachel. Her recovery is rapid enough to allow her to dance in the "Nationals" competition episode, which New Directions wins. Quinn helps Puck study for the test he needs to pass in order to graduate. She tells him that with all they went through, they are bonded for life, and she kisses him. Emboldened, Puck passes his test. Later, Quinn returns her cheerleading uniform to Sue, and the two have a tearful farewell.
Quinn's role as head cheerleader is central to understanding her character. Agron said that she had never had any prior cheer experience before the Pilot. "If I had been [a cheerleader], I would've ended up on crutches," she told Emmy magazine. In an interview with HitFix she said, "I have new respect for the craft, because I slightly hurt myself during the pilot, coming down from one of the stunts. It's better now. I didn't tear something in my knee, but I strained it. Knees are very sensitive, I've learned. It's crazy, because I've been dancing since I was three on my toes and all these things. And you should never say this, but I've never injured myself ever. I'd seen gnarly injuries with dance and all these things. You shouldn't say that, though, because every day is an opportunity to fall, hurt yourself, so that was my experience."
The character's accidental pregnancy storyline received mixed reviews from critics. Tim Stack for Entertainment Weekly deemed it "a good dramatic twist", but hoped that it would not be a long-lasting storyline. Reviews of her storyline became increasingly negative, though Agron was praised for her dramatic acting during the confrontation scene with Quinn's parents in "Ballad". Gerrick D. Kennedy, writing for the Los Angeles Times, was critical of the ongoing pregnancy plot in the episode "Hairography", and noted that he cringed whenever Quinn appeared on screen. Conversely, Bobby Hankinson of the Houston Chronicle enjoyed Quinn in the episode, and wrote: "I love that she can keep her Mean Girls edge while being heartbreakingly sad or as joyful as she was singing "Papa Don't Preach". Reviewing the episode "Journey to Regionals", Entertainment Weekly's Darren Franich called Quinn's birthing scenes—interspersed with Vocal Adrenaline performing Queen's "Bohemian Rhapsody"—both "brilliant" and "terrible". He wrote, "If nothing else, it was definitely the most visually arresting way to represent the birthing process I've ever seen outside of The Miracle of Life. But I kind of liked it. Somewhere, Freddie Mercury is nodding proudly, and saying, 'World, I forgive you for We Will Rock You.'"
Several songs performed by Agron as Quinn have been released as singles, available for digital download, also featured on the show's soundtrack albums. Agron made her musical debut at the end of the episode "Showmance" where she performed Dionne Warwick's "I Say a Little Prayer". Quinn's next solo was in the episode "Throwdown", where she performed The Supremes' "You Keep Me Hangin' On". The song was released on Glee: The Music, Volume 1. Flandez deemed the cover of "Keep Holding On", the ensemble performance on the episode, an "emotionally satisfying showstopper", however was critical of Quinn's cover of "You Keep Me Hangin' On", which he called "thin and jarring". Aly Semigran of MTV observed that Quinn spontaneously bursting into song brought Glee "dangerously close to High School Musical territory". Agron later performed a solo in the episode "Hairography" singing Madonna's "Papa Don't Preach" after her father learns she is pregnant. This performance by Agron was released as a single. She performed a rendition of James Brown's "It's a Man's Man's Man's World" in the episode "Funk". CNN's Lisa Respers France was "slightly disturbed" by Quinn's "weird" performance of "It's a Man's Man's Man's World" using pregnant teenagers as backing dancers.
