Kurt joins the football team and turns out to be a pretty good shooter. By teaching his teammates how to dance Single Ladies (with help from Will Schuester and Finn), he leads to team to their first victory in… forever.
This gives him the courage to come out to his father. Quinn gets pregnant after having an affair with Puck, but lies to Finn telling him it’s his. Puck, Mike Chang and Mark Rutherford (who were all on the football team) join the New Directions.
