 Karofsky is featured in the first eleven episodes of the second season continuing his bullying ways ; in the sixth , " Never Been Kissed " , he especially targets Kurt , who is gay . After he slams Kurt into a locker , Kurt chases after and confronts him , and an increasingly agitated Karofsky abruptly grabs Kurt and kisses him . Before Karofsky can initiate a second kiss , a stunned Kurt shoves him away , and Karofsky leaves . Kurt and his new gay friend Blaine Anderson ( Darren Criss ) later try to talk to him about being gay and closeted , but he denies that the kiss happened and soon resumes his bullying . He even threatens to kill Kurt if he tells anyone else about the kiss . Kurt 's father Burt ( Mike O 'Malley ) finds out about the threat , but not the kiss , and Karofsky is soon expelled , but is allowed to return by the school board because no physical violence to Kurt had been witnessed ; Kurt transfers to Dalton Academy to get away from him .
