Beca comes to apologize, and Jesse initially rebuffs her, telling her to "figure it out." At the finals, Jesse becomes the leader of the Treblemakers, retaining his position as lead singer, along with Benji Applebaum. As the Bellas sing Beca's set list, they sing the theme song to The Breakfast Club, and Beca and Jesse reconcile their differences with a kiss.
He is now a senior student and currently still in a relationship with Beca also the leader of the Treblemakers.
