<P> Salling found it challenging to make the character "more than two - dimensional so he can be likable at the same time", which necessitated "find (ing) the balance between arrogance and cocky and sensible and likable". He recalled that "in the breakdown for the show, when they were describing his character in the very beginning, it's like Puck: a man - child ." Salling explained that Puck has "stars in his eyes, he's hoping to get out of this small town ." Salling gained 20 pounds (9.1 kg) before filming the pilot episode in order to better embody his football playing character . He then lost 30 pounds (14 kg) for a scene in the third episode that required him to be toned, which he described as "an extreme experience". </P> <P> Puck's main basis for relationships at the beginning is sexual rather than romantic . He has sexual encounters with his female pool - cleaning clients and fellow students, including a recurrent relationship with cheerleader Santana Lopez (Naya Rivera) that seems to be casual, though Santana confronts both Mercedes Jones (Amber Riley) and Lauren Zizes (Ashley Fink) when Puck starts pursuing them in the first and second seasons respectively . He falls in love with Quinn Fabray (Dianna Agron) after he takes her virginity and impregnates her despite the fact that she's dating his best friend Finn Hudson (Cory Monteith) at the time, but he can't give up flirting with and seducing others even when Quinn contemplates raising the baby - to - be with him as he wants rather than giving it up for adoption, since she refuses to have sex with him again . The brief pairing of Puck with Rachel Berry (Lea Michele) in the episode "Mash - Up", spurred by his mother urging him to find a Jewish girlfriend, dissolves because he wants Quinn and she wants Finn . Series creator Ryan Murphy was surprised by the positive fan response to their pairing, which he described as "strange and bizarre", explaining that he had believed fans would prefer Rachel to be with Finn . As a result of the response, Murphy planned to revisit their romance later in the season, though nothing much came of it . </P> <P> In the second season, Puck recruits Lauren to join the glee club when the club needs a twelfth member in order to participate in the Sectionals competition . Within a couple of months, he has fallen in love with her, but she doesn't succumb to his blandishments, and he's forced to woo her over a long period of time, starting as friends . He supports her in her first solo for glee club and runs her campaign for prom queen . They are still a couple at the end of the school year . In the fourth episode of the third season, Puck and the adoptive mother of his child Shelby Corcoran kiss . He ends the series dating Quinn . </P> <P> Puck is introduced as a football player and bully at William McKinley High School; he is frequently seen throwing fellow students into dumpsters, or tossing slushies in their faces . It is later revealed that he is Jewish . He is the best friend of Finn, the quarterback, and has a summer pool - cleaning business that leads to sexual encounters with his adult female clients . Despite that, he sleeps with fellow students, including in an on - again, off - again relationship with Santana Lopez (Naya Rivera), a cheerleader, which does not completely end forever until the middle of the second season . Puck initially acts homophobic and mocks Finn for joining the school glee club, New Directions, but later becomes a part of glee club director Will Schuester's (Matthew Morrison) all - male a cappella group, the Acafellas, hoping to impress the mothers at a performance for the school's PTA meeting . He subsequently joins New Directions along with two other members of the football team . When Finn's girlfriend Quinn is impregnated and tells Finn the baby is his, Puck realizes that he is the actual father, and offers to support Quinn . She rejects his proposal, calling him a "Lima loser". Puck begins dating Rachel Berry (Lea Michele), the glee club lead vocalist, after his mother urges him to find a Jewish girlfriend; Rachel is initially resistant, but agrees after Puck sings "Sweet Caroline" for her in front of the glee club . However, Rachel later breaks up with him after a brief romance . </P>
