 The football team has clinched a spot in the championship game , but animosity is running high between glee and non @-@ glee members and harming the team 's performance ; in " The Sue Sylvester Shuffle " , Coach Beiste ( Dot @-@ Marie Jones ) and glee club director Will Schuester ( Matthew Morrison ) force the entire football team to join the glee club for a week to settle their differences and dispel their prejudices . Karofsky is praised by Will as a good performer and dancer , but when the hockey team attacks the football team for their low @-@ status glee club activities , Karofsky leads a walkout from the joint rehearsals by all the non @-@ glee members , and Beiste kicks them off the team . On championship night , the team members — except for Karofsky — relent just before the half @-@ time show , which the team and glee club perform together . Karofsky joins in when he sees the crowd 's positive reaction to the start of the half @-@ time show , a mashup of " Thriller " and " Heads Will Roll " ; the full team ultimately wins the game . Later , in school , Finn approaches Karofsky about joining the glee club and apologizing to Kurt , but Karofsky rejects his suggestion out of hand , since the championship victory has him back on top of the social ladder .
